    Context: Medicinal plants are considered the bases for chemical compounds that could be used therapeutically. Euphorbia paralias belongs to the family Euphorbiaceae. Some species of this family have demonstrated anticancer and antioxidant activities. However, the chemical compounds responsible for the anticancer and antioxidant activities of E. paralias have not been extensively studied. Aims: To identify chemical compounds of E. paralias that possess anticancer and antioxidant properties. Methods: Liquid chromatography/mass spectrometry (LC/MS) was employed to characterise the chemical compounds E. paralias methanolic extract. Using the MTT assay, anticancer activity was investigated. DPPH, ABTS, and FRAP tests were applied to assess the antioxidant action. Results: Several polyphenolic compounds, including phenolic acids, flavonoids, flavanols, fatty acids, terpenoids, and sterols, were identified in the extract. These compounds possess various biological activities. The cancer cell lines most affected by the E. paralias extract were PANC-1 with an IC50 of 60.1 ± 10.1 µg /mL, DLD-1 with an IC50 of 64.3 ± 17.5 µg/mL, and A549 with IC50 of 71.9 ± 9.8 µg/mL. The values of IC50 for the MCF-7 and U87 cancer cell lines were 74.6 ± 15.6 µg/mL and 121.3 ± 17.2 µg/mL, respectively. The cell line of normal HDF had an IC50 of 128.9 ± 11.7 µg/mL. ABTS and DPPH showed that the methanol extract scavenged the free radicals by 89.57% and 92.65%, respectively, compared to ascorbic acid and Trolox positive controls. The FRAP test showed that 1 mg of methanol extract was equivalent to 387.41 μM of Trolox. Conclusions: E. paralias contained various phytochemicals that may have anticancer and antioxidant activities. E. paralias may possess anticancer activity against pancreatic, colon and lung cancers, and it may also have antioxidant activity. Future research is recommended to investigate the isolated phytochemicals from E. paralias.

    The study aims to assess the interaction between fluconazole and sulfonatocalix[4]naphthalene towards enhancing its dissolution performance and antimycotic activity. A solubility study was carried out at different pH conditions, and the results revealed the formation of a 1:1 molar ratio fluconazole-sulfonatocalix[4]naphthalene inclusion complex with an AL type phase solubility diagrams. The solid powder systems of fluconazole-sulfonatocalix[4]naphthalene were prepared using kneaded and co-evaporation techniques and physical mixtures. DCS, PXRD, TGA-DTG, FT-IR, and in vitro dissolution performance characterize the prepared systems. According to physicochemical characterization, the co-evaporation approach produces an amorphous inclusion complex of the drug inside the cavity of sulfonatocalix[4]naphthalene. The co-evaporate product significantly increased the drug dissolution rate up to 93 ± 1.77% within 10 min, unlike other prepared solid powders. The antimycotic activity showed an increase substantially (p ≤ 0.05, t-test) antimycotic activity of fluconazole co-evaporate mixture with sulfonatocalix[4]naphthalene compared with fluconazole alone against clinical strains of Candida albicans and Candida glabrata. In conclusion, sulfonatocalix[4]naphthalene could be considered an efficient complexing agent for fluconazole to enhance its aqueous solubility, dissolution performance, and antimycotic activity.

    Azo dyes account for 70% of dye chemistry, and their importance may grow in the future. Empagliflozin is a sodium-glucose co-transporter-2 (SGLT2) inhibitor. SGLT2 transporters are primarily responsible for glucose reabsorption in the kidney. In 2014, empagliflozin was approved for medical use in the United States and the European Union. With over 4 million prescriptions in 2019, it was the 146th most commonly prescribed medication in the United States in 2019. The spectrophotometric determination of empagliflozin is described using coupling agents such as 3-chloro-4-nitroaniline or sulfanilamide. These methods are straightforward and are based on the reaction of empagliflozin with diazotized products of 3-chloro-4-nitroaniline or sulfanilamide to produce colored azo dyes with absorption maxima at 470 and 480 nm. Empagliflozin was linear from 1.2 to 26.6 µgml −1 or 0.8 to 20.4 µgml −1 when combined with diazotized 3-chloro-4-nitroaniline or sulfanilamide, respectively. Empagliflozin’s molar absorptivity and Sandell’s sensitivity to 3-chloro-4-nitroaniline or sulfanilamide azo dyes were 3.179 × 10 4 l mol −1 cm −1 or 4.367 × 10 4 l mol −1 cm −1 and 1.149 × 10 −2 µgcm −2 or 8.368 × 10 −3 µgcm −2 , respectively. The formed colored azo dyes are stable for more than 12 hours. The optimal reaction conditions and other analytical parameters are assessed. Foreign organic compound interference has been studied. The method has been successfully used to determine empagliflozin in pharmaceutical samples.

    The interaction between meloxicam and sulfonatocalix[4]naphthalene was investigated to improve the meloxicam solubility and its dissolution performance. Solubility behavior was investigated in distilled water (DW) and at different pH conditions. Besides, solid systems were prepared in a 1:1 molar ratio using coevaporate, kneading, and simple physical mixture techniques. Further, they were characterized by PXRD, FT-IR, DCS, and TGA. In vitro dissolution rate for coevaporate, kneaded, and physical mixture powders were also investigated. Solubility study revealed that meloxicam solubility significantly increased about 23.99 folds at phosphate buffer of pH 7.4 in the presence of sulfonatocalix[4]naphthalene. The solubility phase diagram was classified as AL type, indicating the formation of 1:1 stoichiometric inclusion complex. PXRD, FT-IR, DCS, and TGA pointed out the formation of an inclusion complex between meloxicam and sulfonatocalix[4]naphthalene solid powders prepared using coevaporate technique. In addition, in vitro meloxicam dissolution studies revealed an improvement of the drug dissolution rate. Furthermore, a significantly higher drug release (p ≤ 0.05) and a complete dissolution was achieved during the first 10 min compared with the other solid powders and commercial meloxicam product. The coevaporate product has the highest increasing dissolution fold and RDR10 in the investigated media, with average values ranging from 5.4–65.28 folds and 7.3–90.7, respectively. In conclusion, sulfonatocalix[4]naphthalene is a promising host carrier for enhancing the solubility and dissolution performance of meloxicam with an anticipated enhanced bioavailability and fast action for acute and chronic pain disorders.

    Urinary calculi are stones (urolithiasis) that can form anywhere in urinary tract outside of the kidneys and mostly composed of calcium oxalate and phosphate, additionally with elevated throughout the last two decades in the world. Chemical composition plays a major part in nephrolithiasis. Therefore, the high concentrations of lithogenic substances in urine enhance the crystallization method in urine tract system. The most kidney stones form from calcium oxalate, the present study was inspected the effect of the crude aqueous extract as well as the fractionated methanol extract (ethyl acetate, isopropanol, acetone and methanol residue) of paronychia argentea on the crystallization of calcium oxalate salts. The effect of aqueous extract and fractionated methanol extract on the size, number, type of calcium oxalate crystals. Paronychia argentea both the crude aqueous and the fractionated extract, especially ethyl acetate fraction have antiurolithic activity via reducing crystal size as well as activate the formation of calcium oxalate dihydrate (COD) crystals out from calcium oxalate monohydrate (COM) with increasing concentration of extract. The shifting of crystallization process to producing calcium oxalate dihydrate (COD) rather than oxalate monohydrate (COM) and the reducing the crystal size and calcium ion concentration, in addition to the diuretic action of extract plays an important role in controlling urolithiasis.
