The reaction of 2-(α-chlorobenzyl)pyridines with thioacetamide gave 3-methyl-1-arylthiazolopyridinium salts, which form cyanines.It was established that the thiazolopyridinium ring in the dyes has high electron-donor character and a great effective

A series of pyrazolo[3,4-d]pyrimidines were synthesized and their antiviral activity was evaluated in a plaque reduction assay. It is very interesting that this class of compounds provide remarkable evidence that they are very specific for human enteroviruses, in particular, coxsackieviruses. Some derivatives proved to be highly effective in inhibiting enterovirus replication at nanomolar concentrations. SAR studies revealed that the phenyl group at the N-1 position and the hydrophobic diarylmethyl group at the piperazine largely influenced the in vitro antienteroviral activity of this new class of potent antiviral agents. It was found that the pyrazolo[3,4-d]pyrimidines with a thiophene substituent, such as compounds 20-24, in general exhibited high activity against coxsackievirus B3 (IC50=0.063-0.089μM) and moderate activity against enterovirus 71 (IC50=0.32-0.65μM) with no apparent cytotoxic effect toward RD (rhabdomyosarcoma) cell lines (CC5025μ M).

A series of piperazines was synthesized and their effect of reducing serum cholesterol and triglyceride levels in the rat was evaluated.A systematic exploration of the structure-activity relationships led to the synthesis of (R,S)-(3,5-dimethylisoxazol-4-yl)(4-methylpiperazin-1-yl)methane dihydrochloride (M and B 31426), which had potent activity in lowering serum lipid levels at a daily oral dose of 2 mg/kg and was 100 times more potent than clofibrate.
Studies on 1,3-Benzoxazines. II. New Rearrangement Modes in the Reaction of 4-Chloro-2,2-dimethyl-2H-1,3-benzoxazine with Substituted Pyridine N-Oxides
