New bis-aromatic and heterocyclic trisulfide derivatives 5, 7-10 were synthesized by optimizing lead dibenzyl trisulfide natural product (4) to evaluate their anti-tumor activities. Five compounds 5-7, 9, and 10 exhibited potent anti-tumor activities against eight different tumor cell lines with low cytotoxicity against HepG2. Initial SAR was discussed, and MOA of these anti-microtubule agents was
Reactivities of mono and difunctional thiosulfonates toward several nucleophilic compounds, such as thiols, amines and the related compounds, were examined. In the result, some chemical behaviors unexpected were found in addition to the reactivity anticipated. Namely, in the reaction with piperazine, aralkyl thiosulfonate afforded aralkyltrisulfide in about 20% yield, without any formation of sulfenamide. Moreover, aromatic thiosulfonate gave a comparable good yield of 1-phenyl-2-arylsulfonylhydrazine in the reaction with phenylhydrazine, in addition to the formation of phenylhydrazinium salt of aromatic sulfinic acid.
