Abstract
Interaction of (Z)-N-(5-tert-butyl)-2-oxofuran-3(2H)-yliden-2-phenylaminobenzohydrazide (I) with cyanoacetic ester in the presence of triethylamine was used to synthesize the novel derivative (E)-ethyl-2-amino-5-(3,3-dimethyl-4-oxobutyliden)-4-oxo-1-(2-phenylaminobenzamido)-4,5-dihydro-1H-py rrole-3-carboxylate (II). The acute toxicity of this compound was studied, along with its cytotoxic activity against gastrointestinal stromal tumor (GIST) cell line T-1. Compound II showed a concentration- and time-dependent effect comparable with the antitumor compounds imatinib, paclitaxel, etoposide, and hydroxyurea.
