  • OH + HCl Reaction on the Surface of Ice: An Ab Initio Molecular Dynamics Study
    Amit Kumar and Pradeep Kumar

    Journal of Physical Chemistry A, ISSN: 10895639, eISSN: 15205215, Volume: 126, Pages: 1504-1510, Published: 10 March 2022 American Chemical Society (ACS)
    We have investigated the OH + HCl reaction on the surface of ice using Born-Oppenheimer molecular dynamics (BOMD) simulation. The present work revealed that the OH + HCl reaction becomes ∼1 order of magnitude faster on the ice surface compared to the bare reaction. The BOMD simulation also indicates that the Cl radical formed on the ice surface through the title reaction can form two hydrogen bonds at a time with the water molecules present on the ice surface; hence, the Cl radical cannot escape from the ice surface easily.

    Toxins, eISSN: 20726651, Published: February 2022 MDPI AG
    Citrinin (CIT) is a mycotoxin produced by different species of Aspergillus, Penicillium, and Monascus. CIT can contaminate a wide range of foods and feeds at any time during the pre-harvest, harvest, and post-harvest stages. CIT can be usually found in beans, fruits, fruit and vegetable juices, herbs and spices, and dairy products, as well as red mold rice. CIT exerts nephrotoxic and genotoxic effects in both humans and animals, thereby raising concerns regarding the consumption of CIT-contaminated food and feed. Hence, to minimize the risk of CIT contamination in food and feed, understanding the incidence of CIT occurrence, its sources, and biosynthetic pathways could assist in the effective implementation of detection and mitigation measures. Therefore, this review aims to shed light on sources of CIT, its prevalence in food and feed, biosynthetic pathways, and genes involved, with a major focus on detection and management strategies to ensure the safety and security of food and feed.

    Current Drug Delivery, ISSN: 15672018, eISSN: 18755704, Pages: 1494-1504, Published: December2021 Bentham Science Publishers Ltd.
    Background: As per the World Health Organization survey, it has been found that dermatophyte infections are affecting around one-fourth of the world population. The dermatophytes are commonly keratinophilic in nature which can multiply and invade the keratinized tissues and affect various parts of the human body like nails, skin, and hair. The luliconazole is an antifungal drug utilized against dermatophytes which causes athlete's foot and ringworm etc. fungal infections of the skin or nails caused by Candida albicans (C.P. Robin) Berkhout and Trichophyton mentagrophytes (Robin) Blanchard. Objective: The study aimed to develop the luliconazole topical cream with turmeric oil and penetration enhancer to improve permeability and enhance antifungal activity. Methods: To prepare the luliconazole topical cream, various compositions of formulation were melted and mixed with varying concentrations of turmeric oil. The oil, drug, and aqueous phases were prepared separately and mixed stepwise in a vessel under continuous stirring at control conditions. Result: The optimized LC2 cream was showed pH 6.45±0.12, which is considered suitable to avoid irritation upon topical application. The LC2 cream formulation also showed significantly (p<0.05) more permeability with a permeation flux (0.347 mg/cm2/h) against an aqueous suspension of the drug (0.215 mg/cm2/h). The LC2 cream was followed the Higuchi model and showed the drug release from cream via a diffusion mechanism with super case II transport mechanism. Furthermore, the antifungal activity of optimized cream was found good than marketed cream. Conclusion: It is concluded that the prepared luliconazole cream can be an effective anti-fungal treatment with enhanced drug delivery into the skin to treat athlete's foot and ringworm etc. caused by dermatophytes namely C. albicans and Trichophyton spp.

  • Corrosion inhibitive properties of 5-(4-aminophenyl)-1,3,4-oxadiazole-2-thiol and 5-(4-methylphenyl)-1,3,4-oxadiazole-2-thiol on mild steel in 1.0 M HCl Solution

    Asian Journal of Chemistry, ISSN: 09707077, Pages: 2953-2964, Published: December 2021 Asian Journal of Chemistry
    The corrosion inhibition consequence of 5-(4-aminophenyl)-1,3,4-oxadiazole-2-thiol (APOT) and 5-(4-methylphenyl)-1,3,4-oxadiazole-2-thiol (MPOT) were accomplished by employing weight loss measurement, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization measurement and scanning electron microscope (SEM). An impact of immersion time 12.0 h and different temperatures (298, 308 and 318 K) with solution of 1.0 M HCl, which include various concentration of inhibitor at the corrosion of mild steel were designed. Weight loss measurement showed that with enhancing the concentration of these studied inhibitors the percentage inhibition efficiency (IE%) enhances, but corrosion rate (CR) diminishes while reverse condition in case of temperatures change. The electrochemical impedance spectroscopy examine pointed out that the charge transfer resistance (Rct) values enhances and consequently the double layer capacitance (Cdl) values diminishes with rising each inhibitor concentration in 1.0 M HCl and also there is a formation of adsorption coating at the metal surface. Polarization measurement showed that both APOT and MPOT perform as mixed type corrosion inhibitors. Furthermore, the adsorption behaviour on surface of mild steel for each studied inhibitor results the Langmuir adsorption isotherm. Surface conduct of mild steel also designed through the SEM and energy dispersive X-ray (EDX) analysis and concludes that there is evolution of inhibitive film of APOT and MPOT on the surface of mild steel.

    Recently, supramolecular self-assembled core–shell nanostructures have emerged as advanced and notable drug delivery vehicles in biomedical arena for human health. Here, we have modified curcumin via Michael addition reaction with 3-mercaptopropionic acid followed by preparation of an amphiphatic conjugate employing hydrophilic polyethylene glycol monomethyl ether (mPEG). The synthesized compounds, curcumin-S-propionic acid (Cur-S) and curcumin-S-propionoyl-mPEG (Cur-S-mPEG), were spectroscopically characterized. Self-assembly of Cur-S-mPEG into micellar nanostructures was monitored by dynamic light scattering, which revealed the size of these nanostructures in the range of ~ 104 nm. Transmission electron microscopic analysis showed the size of these nanostructures ~ 26 nm. These micelles with hydrophobic pockets were then demonstrated to entrap hydrophobic therapeutics, ornidazole (Oz) and sulfasalazine (Sz), successfully with high efficiency. Drug-loaded formulations, Cur-S-mPEG(Oz) and Cur-S-mPEG(Sz), showed sustained release of drugs over a longer duration, particularly, a higher release at neutral pH 7.2 displaying the usefulness of the nanocarrier for colonic delivery. MTT assay performed on HEK 293 and Hep G2 cells displayed the non-toxic nature of the nanocarrier on normal cells (HEK 293 cells) while toxic on cancer cells (Hep G2 cells).

  • Disaccharide-polyethylenimine organic nanoparticles as non-toxic in vitro gene transporters and their anticancer potential
    Reena Singh and Pradeep Kumar

    Bioorganic Chemistry, ISSN: 00452068, eISSN: 10902120, Volume: 112, Published: July 2021 Elsevier BV
    Polyethylenimines (PEIs) have been shown as efficient gene delivery vectors due to their unique properties, however, toxicity as well as non-specific interactions with the tissues/cells because of high charge density have hampered their use in clinical applications. To counter these concerns, here, we have prepared disachharide-PEI organic nanoparticles by mixing PEIs with non-reducing disaccharides, i.e. trehalose (TPONs) and sucrose (SPONs), under mild conditions. The fabricated nanoparticles were complexed with pDNA and size of these complexes was found in the range of ~130-162 nm with zeta potential ~ +8-25 mV. Further evaluation of these nanoparticles revealed that substitution of disaccharides on PEIs successfully augmented cell viability. Transfection efficiency exhibited by these complexes was significantly higher than the unmodified polymer and the standard, Lipofectamine, complexes. Fabrication of organic nanoparticles did not alter the buffering capacity considerably which was found to be instrumental during endosomal escape of the complexes. Among both the series of nanoparticles, trehalose-PEI organic nanoparticles (TPONs) exhibited greater pDNA transportation potential than sucrose-PEI organic nanoparticles (SPONs) which was also established by flow cytometric data, wherein percent cells expressing GFP was higher in case of TP/pDNA complexes as compared to SP/pDNA complexes. Interestingly, TPONs also showed promising anticancer activity on cancer cell lines i.e. Mg63, MCF-7 and HepG2. Overall, the results advocate promising potential of disaccharide-PEI organic nanoparticles as efficient gene delivery agents which can be used effectively in future gene therapy applications along with anti-cancer competence of TPONs.

  • Tight Binding of Plasmid DNA With Self-Assembled Tetramethylguanidinium Conjugated Polyethylenimine Suppresses Transfection Efficiency
    Santosh Yadav, Ashwani Kumar Sharma, and Pradeep Kumar

    Frontiers in Nanotechnology, eISSN: 26733013, Published: 25 June 2021 Frontiers Media SA
    Here, we have demonstrated that on modification of linear polyethylenimine (lPEI, LP) with amphiphilic 3-bromopropyltetramethylguanidinium (PTMG) linker, the transfection efficiency exhibited by the modified polymers decreased while cell viability improved. A series of LP-PTMG polymers was synthesized by the reaction of varying amounts of 3-bromopropyl tetramethylguanidinium linker with lPEI (25 kDa). These modified polymers interacted efficiently with pDNA and formed nanosized complexes as shown by dynamic light scattering analysis. The size of the complexes in the series LP-PTMG/pDNA was observed in the range of ∼178–205 nm. The interaction of modified polymers with plasmid DNA was stronger than linear PEI as evidenced by heparin release assay which showed ∼83% pDNA release from LP-PTMG-3/pDNA complexes in comparison to ∼95% in lPEI/pDNA complexes on treatment with same amount of heparin suggesting the formation of self-assembled structures in modified polymers. The transfection studies in HeLa and Chinese hamster ovary cells showed a decrease in transfection efficiency of LP-PTMG polymers, the reason for this may be strong binding of modified polymers with pDNA due to accumulation of charge on the surface. This finding showed the significance of optimum binding of polymer and DNA to form polyplexes as well as release of DNA from the polyplexes.
