Thiosemicarbazones possessing electron‐donating and electron‐withdrawing groups were prepared, their spectral characteristics determined. In all cases, the spectra showed that one isomer was formed, allowing further functionalization to molecules of biological interest. We provide NMR data for some thiosemicarbazones semicarbazones. also evidence 2‐pyridyl thiosemicarbazone, syn slowly converts into anti in dimethyl sulfoxide solvent with first‐order kinetics.

There remain several key challenges to existing therapeutic systems for cancer therapy, such as quantitatively determining the true, tissue-specific drug release profile <italic>in vivo</italic>, well reducing side-effects an increased standard of care.
Sexually active women represent the fastest growing human immunodeficiency virus (HIV)/acquired syndrome risk group. In an effort to develop a vaginal microbicidal contraceptive potentially capable of preventing HIV transmission as well providing fertility control, we previously reported synthesis novel nonnucleoside inhibitors (NNIs) HIV-1 reverse transcriptase with sperm-immobilizing activity (SIA). To gain further insight into structure-function relationship controlling these two...

Abstract A detailed NMR investigation of the chemical shifts hydrogen and carbon atoms associated with structure naturally occurring alkaloid colchicine was conducted using high field NMR. Initially, experimental for in chloroform DMSO were compared to values calculated density functional theory (DFT). There significant deviations observed solvent, but these only slight solution. Dilution solution changed improved agreement DFT calculations, suggesting self-aggregation at higher...
Detergent-based vaginal microbicides, in addition to their high contraceptive failure rates, cause mucosal erosion and local inflammation that might increase the risk of heterosexual human immunodeficiency virus (HIV) transmission. In a systematic effort identify microbicide potentially capable preventing sexual transmission HIV as well providing fertility control, series novel aryl phosphate derivatives 5-bromo-6-methoxy-3'-azido-3'-deoxythymidine (AZT; zidovudine) were synthesized examined...
ABSTRACT Two highly potent dihydroalkoxybenzyloxopyrimidine (DABO) derivatives targeting the nonnucleoside inhibitor (NNI) binding site of human immunodeficiency virus (HIV) reverse transcriptase (RT) have been designed based on structure NNI pocket and tested for anti-HIV activity. Our lead DABO derivative, 5-isopropyl-2-[(methylthiomethyl)thio]-6-(benzyl)-pyrimidin-4-(1 H )-one, elicited inhibitory activity against purified recombinant HIV RT abrogated replication in peripheral blood...
