Cytotoxic effects of 4-{3-[5-(n-tolyl)isoxazol-3-yl)ureido)butanoic acid, cisplatin and their combination in vitro and in vivo

Abstract

In experiments on Ehrlich's ascitic carcinoma cell culture in mice tumor-bearers, the cytotoxic action of heterocyclic compound PS 1603 (4-{3-[5-(n-tolyl)isoxazol-3-yl)ureido)butanoic acid, cisplatin and their combination on the mitogenic activity, the cell death (in vitro), the tumor mass, and the animals' lifetime (in vivo) has been studied. It has been established that PS 1603 has a minor (in vitro) and mild (in vivo) antitumoral effect. The combination of a heterocyclic compound and a chemo-therapeutic agent in a ten-fold reduced dose decreases the expressed effects of a cytostatic agent in concentrations close to clinical ones but does not intensify them.
