Two new of N’-benzylidenebenzohydrazide (NBB) derivatives were successfully synthesized and yielded 50–58%. FTIR, ESI-MS, 1H-NMR and 13C-NMR were used to investigate the characteristic of NBB derivates. The structure and relationship of NBB derivatives into α-glucosidase and α-amylase as good targets for diabetes treatment were evaluated using in silico screening. Molecular Mechanics-Poisson Boltzmann/Generalized Born Surface Area (MM-PB/GBSA) was used to calculate the free binding energy (ΔGbind (MM-GBSA)) of NBB to α-glucosidase and α-amylase receptors showed that the results of −0.45 and −20.79 kcal/mol respectively. In the ortho position, NBB derivatives exhibited electron donating groups (EDG like -OCH3, -OH and -Cl with binding free energies of −21.94, −6.71 and 21.94, respectively, and acarbose, a native ligand energy of 32.62 kcal/mol. In addition, the binding free energy of N-2-(-OCH3, -OH and -Cl)-NBB to the α-amylase receptor showed the number of −39.33, −43.96, −42.81, respectively and −46.51 kcal/mol in comparing with a native ligand. As a result, it was found that all the NBB derivatives were able to interact with several amino acids in the α-glucosidase cavity as well as the native ones, including Ala281, Asp282, and Asp616. NBB and native ligand showed similar interaction between α-amylase with Gly110 amino acid residue.

Sargassum is a brown seaweed rich in fucoidan which is a sulfated polysaccharide. This study aims to examine the conventional and microwave-assisted extraction (MAE) methods to optimize fucoidan extraction from Sargassum plagiophyllum with 0.1 M HCl and water solvents. The extraction of fucoidan was conducted in two different methods, conventional (C) and MAE (M) methods. Microwave-assisted extraction was performed at 450, 600, and 700 W microwave power for five minutes, then the extracted fucoidan was determined for its sulfate and fucose contents, as well as antioxidant activities. In both the conventional (CAwe) and MAE methods (MAfa7), the maximum yields of fucoidan crude extract produced in 0.1 M HCl solvent were 19.10 and 19.20%, respectively. The highest sulfate (MAfa7; 6.14%), and fucose content (MAaf7; 5.95 mg/100g) were found in the HCl solvent using the MAE method. Based on the results, the MAE approach with HCl solvent was a more efficient technology for extracting fucoidan from S. plagiophyllum than the conventional method.

Background and Objective: Fucoidan extract from the Sargassum plagiophyllum brown seaweed are renowned for its anticancer and antibacterial activities. Fucoidan is one of the ingredients of S. plagiophyllum that can be extracted by conventional methods and new methods, one of which is microwave assisted extraction (MAE). Research on the extraction of fucoidan from S. plagiophyllum was still limited. Thus, an advanced experiment on how microwave assisted extraction (MAE) of fucoidan was conducted in this study and its activities against Escherichia coli bacteria and HeLa cancer cells were studied. Materials and Methods: Sargassum plagiophyllum was collected from the Gunung Kidul Coast in Yogyakarta, Indonesia. Fucoidan extract of S. plagiophyllum was acquired by applying the MAE method at 600 W for 5 min and using hydrochloric acid as a solvent. The cytotoxicity and antibacterial assays were performed using the MTT assay and the agar plate diffusion methods, respectively. Results: The yield of the fucoidan extract examined was 9.90% (w/w), which consisted of 2.60% sulfate and 2.33 mg 100 g1 fucose. The finding indicated that fucoidan extract exhibits no antibacterial action and the cytotoxicity against the HeLa cell line was 27.82 mg mL1. Conclusion: The MAE technique was proven to support the fucoidan extraction from S. plagiophyllum successfully. Therefore, the fucoidan extract has proven to have promise beneficial in anticancer activity.

This research aimed to determine the topical administration effect of the combination of Sargassum duplicatum and Garcinia mangostana extracts to ameliorate diabetic open wound healing. The study used 24 adult males of Mus musculus (BALB/c strain, 3–4 months, 30–40 g). They were divided into normal control groups (KN) and diabetic groups. The diabetic group was streptozotocin-induced and divided further into three treatment groups: the diabetic control group (KD), the S. duplicatum treatment group (PA), and the combination of S. duplicatum and G. mangostana treatment group (PAM). The dose of treatment was 50 mg/kg of body weight. Each group was divided into three treatment durations, which were 3 days, 7 days, and 14 days. The wound healing process was determined by wound width, the number of neutrophils, macrophages, fibroblasts, fibrocytes, and collagen density. Histological observation showed that the topical administration of combination extracts increased the re-epithelialization of the wounded area, fibroblasts, fibrocytes, and collagen synthesis. The topical administration of combination extracts also decreased the number of neutrophils and macrophages. This study concluded that the topical administration of the combination of S. duplicatum and G. mangostana extracts improved the open wound healing process in diabetic mice.

Intense efforts to develop alternative materials for gelatine as a drug-delivery system are progressing at a high rate. Some of the materials developed are hard capsules made from alginate, carrageenan, hypromellose and cellulose. However, there are still some disadvantages that must be minimised or eliminated for future use in drug-delivery systems. This review attempts to review the preparation and potential of seaweed-based, specifically carrageenan, hard capsules, summarise their properties and highlight their potential as an optional main component of hard capsules in a drug-delivery system. The characterisation methods reviewed were dimensional analysis, water and ash content, microbial activity, viscosity analysis, mechanical analysis, scanning electron microscopy, swelling degree analysis, gel permeation chromatography, Fourier-transform infrared spectroscopy and thermal analysis. The release kinetics of the capsule is highlighted as well. This review is expected to provide insights for new researchers developing innovative products from carrageenan-based hard capsules, which will support the development goals of the industry.

A diabetic foot ulcer is an open wound that can become sore and frequently occurs in diabetic patients. Alginate has the ability to form a hydrophilic gel when in contact with a wound surface in diabetic patients. Xanthones are the main compounds of mangosteen rind and have antibacterial and anti-inflammatory properties. The purpose of this research was to evaluate the wound healing and antioxidants assay with a combination of alginate from S. ilicifolium and mangosteen rind combination extracts on a diabetic mice model. The characterization of alginate was carried out by size exclusion chromatography with multiple angle laser light scattering (SEC-MALLS) and thermogravimetric analysis (TGA). The M/G ratio of alginate was calculated by using proton nuclear magnetic resonance (1H NMR). The antioxidant activity of mangosteen rind and the combination extracts was determined using the DPPH method. The observed parameters were wound width, number of neutrophils, macrophages, fibrocytes, fibroblasts, and collagen densities. The 36 male mice were divided into 12 groups including non-diabetic control (NC), diabetes alginate (DA), alginate–mangosteen (DAM), and diabetes control (DC) groups in three different groups by a histopathology test on skin tissue. The treatment was carried out for 14 days and mice were evaluated on Days 3, 7, and 14. The SEC-MALLS results showed that the molecular weight and dispersity index (Ð) of alginate were 2.77 × 104 Dalton and 1.73, respectively. The M/G ratio of alginate was 0.77 and described as single-stage decomposition based on TGA. Alginate, mangosteen rind extract, and their combination were divided into weak, medium, and strong antioxidant, respectively. The treatment of the DA and DAM groups showed a decrease in wound width and an increase in the number of fibrocytes, fibroblasts, and macrophages. The number of neutrophils decreased while the percentage of collagen densities increased for all the considered groups.

In drug release kinetics, the drug-matrix interaction is one of the important mechanisms to be dictated. Unfortunately, there is still minimum information discussing the effect of interaction between a drug and its matrix to the release profile of the drug. Therefore, there is an urgent need to conduct research related to the study of drug-matrix interaction. This paper reports the preparation of a drug delivery system (DDS) in the form of hard-shell capsules containing salicylamide (SCA) and analyses its drug-matrix interaction via dissolution test at different pH media and various release kinetics models. The matrix of hard-shell capsules was prepared from κ-carrageenan (CRG), crosslinked with maltodextrin (MD), and plasticized by sorbitol (SOR). The chemical properties of SCA were compared with paracetamol (PCT) using computational analysis to help to depict its drug-matrix interaction. The statistical analyses showed that SCA and PCT at pH 1.2, 4.5, and 6.8 had all different release profiles. Based on the goodness of fit evaluation, the diffusion mechanism of SCA at pH 1.2 and 4.5 could be best described by the Peppas-Sahlin model while the zeroth-order model fitted the dissolution profile at pH 6.8. In summary, it was proven that a different drug-matrix interaction produced a different dissolution profile.

A field experiment Porang (Amorphophallus mueleri Blume) has the potential to be developed as a functional food ingredient because it contains high levels of glucomannan. Research on the acute toxicity test of macerated porang flour has been carried out. The results of research showed a toxic effect which was characterized by high SGOT and sodium levels. The purpose of this study was to find out the safety level of consuming porang flour with lowered calcium oxalate content. This research was an experimental study designed in one directional-pattern Completely Randomized Design using 5 treatments of porang flour administration with doses of 0; 5; 50; 500; 5000 and 15000 mg/kgbw and 6 repetitions for 60 days using Wistar-strain white rats (Rattus norvegicus) as laboratory animals. The results showed that during the treatment, the administration up to a dose of 500 mg/kgbw did not give a significant difference to all observed variables. The administration of 5000 and 15000 mg/kgbw gave a significant difference on the changes in body weight, the addition of the amount of water drunk, the levels of Calcium, Potassium and Sodium in the blood, SGOT and SGPT values, and observation on necrotic cells in the kidneys. The administration of the highest porang flour dosage, namely 15000 mg/kgbw did not cause any rat mortality and did not cause any real cell damage to the liver, but caused hyperactive behavior in female rats.

Introduction: Diabetes mellitus (DM) is a chronic disease with diverse and complex metabolic disorders. DM can be identified with hyperglycemic conditions. In 2017, Indonesia ranked sixth in the world for the highest number of diabetic patients after China, India, United States, Brazil, and Mexico.
Objective: This study aims to determine the combined effect of alginate extract from Sargassum duplicatum and Sargassum ilicifolium with okra (Abelmoschus esculentus) and mangosteen (Garcinia mangostana) pericarp extracts to ameliorate the wound width process, the number of neutrophil cells, macrophages, fibroblasts, fibrocytes, and collagen density in streptozotocin-induced diabetic mice.
Methods: This study used male mice (strain BALB/C, weighting 30±5 g each) which were grouped into four groups; normal control with water only; diabetic control group; combination treatment group with S. duplicatum extract, A. esculentus extract, and G. mangostana extract; and combination treatment group with S. ilicifolium extract, A. esculentus extract, and G. mangostana extract. The diabetic control group and combination treatment groups were injected with multiple low doses of streptozotocin (STZ) at 30 mg/kg BW intraperitoneally. The combination extract dose given in treatment groups was 50 mg/kg BW. Measurement of fasting blood sugar levels was done before and after the STZ injection. The mices skin was cut in the gluteal section as long as 1 cm, then treated topically in three different time periods namely 3, 7, and 14 days. Histological preparation and analysis were conducted on the 15th day.
Results: The administration of A. esculentus extract and G. mangostana extract combined with S. duplicatum and S. ilicifolium increased wound healing indicator rate, decreased neutrophile cell count (NCC) and fibrocyte cell count (FCCC), and increased collagen synthesis as an extracellular matrix (ECM). The treatments could restore the open wound healing process of diabetic mice to their normal state. There were no significant differences in macrophage cell count (MCC) and fibroblast cell count (FBCC). The histopathology showed that the combination treatment groups also could accelerate the wound healing process in mice skin.
Conclusion: In summary, this study addressed that the administration of A. esculentus extract and G. mangostana extract combined with S. duplicatum and S. silicifolium extracts could ameliorate open wound healing in diabetic mice.

Diabetes mellitus is a group of metabolic disorders characterized by high blood-glucose levels over a prolonged period that causes complications when an open wound is present. Alginate is an antioxidant and a good absorbent of exudates. Okra fruit contains flavonoids that can act as antioxidants. The antioxidant properties of extracts combination reduce blood-glucose levels significantly to accelerate the activities of wound-healing processes on diabetic mice. Alginate was characterized by Size Exclusion Chromatography-Multiple Angle Laser Light Scattering (SEC-MALLS), thermal stability and Proton Nuclear Magnetic Resonance (1H-NMR). The evaluation of wound healing on 36 male mice were divided into 12 groups including normal control (NC), diabetics control (DC), alginate (DA) and alginate–okra (DAO) groups in three different times by histopathology test on skin tissue. The results of SEC-MALLS analysis showed that alginate as single and homogeneous polysaccharide. The 1H-NMR spectrum showed that the mannuronate/guluronate ratio of the used alginate was 0.91. Alginate, okra fruit extract and their combination were classified as moderate and strong antioxidants. The numbers of fibrocytes, fibroblasts, collagen densities had significantly increased from three to seven days. In contrast, wound width, neutrophil, macrophages had significantly decreased at 14 days. The administration of extracts combination increased the re-epithelization of the wound area and wound-healing process on diabetic mice.

This study aims to evaluate the effects of alginate extract from Sargassum ilicifolium and okra (Abelmoschus esculentus) pods extract on the re-epithelialization rate of the wound area and the number of neutrophils, macrophages, fibroblasts, fibrocytes, and collagen density in streptozotocin-induced diabetic mice. This study was done in vivo using male mice (strain BALB/C, 3 to 4 months old, 30 to 40g). The normal control group (KN) and the diabetic groups (induced by streptozotocin). The diabetic group was divided into 9 groups: three diabetic control groups (KD), three alginate treatment groups (KAI), and three treatment groups of alginate-okra (Abelmoschus esculentus) pods extract (KAIO). The treatment dose was 50 mg/kg body weight. Measurement of fasting blood sugar levels was done before and after streptozotocin injection. The treatment was carried out in three different time periods: 3 days, 7 days, and 14 days. Then, mice skin was cut and proceed for histopathological analysis. Interestingly, we indicated that the administration of okra (Abelmoschus esculentus) pods extract combined with alginate from Sargassum ilicifolium could increase the rate of re-epithelialization of the wound area, increase the number of neutrophils, macrophages, fibroblasts, fibrocytes, as well as increase synthesized collagen. The combined extract was able to improve the healing process of open wounds in diabetic mice. Therefore, it can be concluded that the administration of alginate from Sargassum ilicifolium and okra (Abelmoschus esculentus) pods extract was able to improve open wounds healing in diabetic mice due to the role of antioxidant from polysaccharides and quercetin which acted as anti-hyperglycemic to anti-inflammatory properties.

AbstractThe release of drugs from solid drug delivery materials has been studied intently in recent years. Quantitative analyses achieved from in vitro dissolution becomes easier if a zero-order mathematical model is used. Non-gelatin nutraceutical hard-shell capsules of zero size (approximately 0.7-0.8 cm) were produced from carrageenan-based natural polymers, namely carrageenan-alginate (CA) and carrageenan-starch (CS). Disintegration, dissolution and zero-order drug release kinetics of hard-shell capsules containing 100 mg of salicylamide were studied. The disintegration time of CA and CS were observed to be less than 30 min for both CA and CS. In vitro dissolution profile showed that the percentage dissolution of CA capsules was better at pH 4.5, while that of CS was poor at pH 1.2, 4.5 and 6.8. Determination of drug release kinetics profiles of carrageenan-based hardshell capsules utilized the Noyes-Whitney and Peppas-Sahlin modification rules for zero-order. The drug release from carrageenan-based capsules followed zero-order kinetics, especially at pH 6.8, and was compared to the Higuchi model. Salicylamide in CA hard-shell capsules at a pH 6.8 had a release rate constant (kH) of 2.91 %(ppm/ ppm) min-1/2, while the release rate constant of CS was 0.36 %(ppm/ppm) min-1.

Hard-shell capsules commonly consist of gelatin which is not a universal material considering it is extracted from animal parts. Moreover, the mad cow disease triggered the scrutinization of the use of gelatin in pharmaceutical products. Hence, an alternative to conventional hard-shell capsules is needed. Carrageenan- (CRG-) based hard-shell capsules were successfully prepared by cross-linking CRG with maltodextrin (MD) and plasticizing with sorbitol (SOR). These CRG-MD/SOR hard-shell capsules were produced as an alternative to conventional hard-shell capsules in the oral drug delivery system (DDS). The physical properties of CRG-MD/SOR capsules were characterized using the degree of swelling, FTIR, and SEM analyses. The disintegration and dissolution profile release of paracetamol from CRG-MD/SOR hard-shell capsules was performed in an aqueous medium with three different pH levels. The degree of swelling of CRG-MD/SOR was 529.23±128.10%. The main peaks in the FTIR spectrum of CRG-MD/SOR were at 1248, 930, 847, and 805 cm−1 for ester sulfate groups, 3,6-anhydrogalactose, galactose-4-sulfate, and 3,6-anhydrogalactose-2-sulfate, respectively. The SEM analysis exhibited minuscule pores on the surface of CRG and CRG-MD/SOR at 5000 times of magnification. The CRG-MD/SOR capsules required 18.47±0.11 min on average to disintegrate. The CRG-MD/SOR dissolution was better in a weakly acidic medium (pH 4.5) than in a strongly acidic (pH 1.2) and neutral (pH 6.8) media. Based on the aforementioned results, CRG-MD/SOR capsules are the potential candidate to replace conventional hard-shell capsules.

Drug delivery material is one of popular topics of research in this era because the developmet of medicines require a good carrier of the drugs produced and synthesized. However, recent produced capsules were made from animal’s extract such as bone or skin that could not be suitable for everyone, especially the ones with animal’s meat intolerant. Hard shell capsules were produced from κ-carrageenan-alginate (CA) and κ-carrageenan-starch (CS) of cassava. First order kinetics of salicylamide released from hard shell capsules of CA and CS were determined using the Noyes-Whitney modification equations. The optimum k1 of gelatin capsules calculated was 0.0108 ppm/min at pH 6.8, CA was 0.0.0493 ppm/min, and CS was 0.0237 ppm/min. This means that CA and CS could be recommended. Further development is needed to produce the best CA and CS capsules as drug delivery material.
