The colchicine site inhibitors (CSIs) displayed both antimitotic and vascular disrupting activities, therefore are promising potential antitumor agents. In this study, a series 1-phenyl-4,5-dihydro-2H-benzo[e]indazoles were found as new CSIs of which the bioactive configuration was locked. Among them, compounds C1 and C2 displayed the best activity, with tubulin polymerization IC50 of 3.4 and 1.5 μM, and growth IC50 of low nanomolar concentrations against human colon cancer cell lines. In addition, compound C1 showed excellent broad-spectrum antitumor activity in the NCI-60 Human Tumor Cell Lines Screen, encouraging further study of this antitumor compound.
Synthesis of 2-tetralones via a novel 1,2-carbonyl transposition of 1-tetralones
Pryde, David C. Henry, Steven S. Meyers
Simple acidic hydrolysis of epoxyamides 4, derived from 1-tetralones, furnishes the corresponding 2-tetralones in good yield.
