sodium-acetate--anhydrous and HIV-Infections

The necessity for newer anti-HIV and anti-tubercular medications has arisen as a result of the prevalence of opportunistic infections caused by HIV (human immunodeficiency virus).. A series of ten new hydrazono 1,3-thiazolidin-4-one derivatives were synthesized in one-pot and evaluated for anti-HIV and anti-tubercular activities. Molecular Docking was accomplished with HIV-1 reverse transcriptase protein (PDB ID: 1REV) and Mycobacterium Tuberculosis (M. tuberculosis) H37Rv protein (PDB ID: 2YES) receptors along with drug-likeness and ADMET properties.. One-pot synthesis of hydrazono 1,3-thiazolidin-4-one derivatives was carried out by ketones, thiosemicarbazide and ethylchloroacetate with the catalyst of anhydrous sodium acetate. All the synthesized compounds were characterized and evaluated for their in-vitro anti-HIV and also evaluated for their in-vitro anti-tubercular activity against M. tuberculosis H. From the novel synthesized molecules, none of the molecule is as effective as standards for anti-HIV and anti-tubercular drugs and hence can be further explored for its potential activities. Furthermore, derivatization was made to achieve more potent compounds for anti-HIV and anti-tubercular drugs.

The use of polymeric devices for controlled sustained delivery of drugs is a promising approach for the prevention of HIV-1 infection. Unfortunately, certain microbicides, when topically applied vaginally, may be cytotoxic to vaginal epithelial cells and the protective microflora present within the female genital tract. In this study, we evaluated the impact of hydroxychloroquine (HCQ)-loaded, reservoir-type, polyurethane intravaginal rings (IVRs) on the growth of Lactobacillus crispatus and Lactobacillus jensenii and on the viability of vaginal and ectocervical epithelial cells. The IVRs were fabricated using hot-melt injection molding and were capable of providing controlled release of HCQ for 24 days, with mean daily release rates of 17.01 ± 3.6 μg/ml in sodium acetate buffer (pH 4) and 29.45 ± 4.84 μg/ml in MRS broth (pH 6.2). Drug-free IVRs and the released HCQ had no significant effects on bacterial growth or the viability of vaginal or ectocervical epithelial cells. Furthermore, there was no significant impact on the integrity of vaginal epithelial cell monolayers, in comparison with controls, as measured by transepithelial electrical resistance. Overall, this is the first study to evaluate the effects of HCQ-loaded IVRs on the growth of vaginal flora and the integrity of vaginal epithelial cell monolayers.
