Obtaining and Determining Antiviral and Antibacterial Activity of S-Esters of 4-R-Aminobenzenethiosulfonic Acid

A number of S-esters of 4-R-aminobenzene¬thiosulfonic acids were synthesized via alkylation of the sodium salt of 4-acetylaminobenzenethiosulfonic acid with various alkylating agents and acylation of the corresponding esters of 4-aminobenzenethiosulfonic acid with metha-cryloyl chloride. For obtaining S-methyl 4-(acetyla-mino)benzenesulfonothioate, it was developed a synthetic technique corresponding to the basic principles of "green chemistry". The degree of compound cytotox-icity was measured by determining A-549 cell growth using colorimetric method.

Physico-Chemical Characterization of Bioactive Mixed Ligand Complexes of Antimony with 3,5-Diarylsubstituted Pyrazolinates and O,O’-Alkylene Dithiophosphates

Antimony(III) complexes of 3(2’-hydroxyphenyl)-5-(4’-substituted phenyl) pyrazolinates and O,O’-alkylene dithiophosphate of the type [Sb(C15H12N2OX)(GO2PS2)]Cl and [Sb(C15H12N2OX)2(GO2PS2)] (where GO2PS2 – deprotonated O,O’-alkylene dithiophosphate; C15H12N2OX – deprotonated 3(2'-hydroxyphenyl)-5-(4’-subsitutedphenyl) pyrazolinates; X = –H,–CH3, –OCH3 and –Cl; G = –C(CH3)2CH2CH(CH3)–) have been synthesized and characterized by elemental analysis (C, H, N, Cl and Sb), molecular weight study by FAB mass, electronic spectral studies, far and mid IR, multinuclear NMR (1H,13C and 31P).
