Abstract

The lab made an effort to prepare some biological active cantharidinimines by heating the reactant 1 and 2a-g, 5h-i and 7j-r amines to suitable temperature with ethanol to provide 18 N- thiazolyl-, sulfanyl-, aminopyridyl-, bromopyridyl-, alkylpyridyl- and hydroxypyridylcantharidinimines 3a-g, 4a-c, 6h-i and 8j-r in yield of 4-77% (Chart 1). These cantharidinimine derivatives were tested for their capabilities to suppress growth of the human carcinoma cell lines, HL-60, MCF7, Neuro-2a and A549, because the incidence rate is more prominent in Asian countries than western countries. Compounds 3c-d and 6h-i were found to have some antitumor activity in HL-60 but less activity in MCF cell and compounds 8j-l displayed some inhibition effects to A549 cell line, but less effect to Neuro-2a cell line. Compounds 8m-r had no cytotoxic effect against both cell lines. The cytotoxic effects of these cantharidinimine compounds seemed to be better than the cantharidinimide compounds which we had mentioned several years ago.
