Synthesis and evaluation of substituted naphthalimide nitrogen mustards as rationally designed anticancer compounds.
Bromonapmustine 4a and chloronapmustine 4b, two new nitrogen mustards of substituted naphthalimides, have been synthesized as mixed-function anticancer compounds from 4-bromo- and 4-chloro-N-(2-hydroxyethyl)-naphthalimide respectively following a three-step process. Their chemical alkylating activity exceeded that of nor-HN2. Their antitumour efficacy were assessed in vivo in two murine ascites tumours, namely Ehrlich ascites carcinoma (EAC) and Sarcoma-180 (S-180) by measuring the increase in median survival times (MST) of drug treated (T) over untreated control (C) mice. Two standard clinical drugs, namely endoxan (cyclophosphamide) and 5-fluorouracil (5-FU) were used as positive controls for comparison. Both of them have displayed substantial and reproducible antitumoural activity in these tumours comparable with 5-FU. These compounds inhibit the synthesis of DNA and RNA in S-180 tumour cells. These were further screened in vitro in 3 different human tumour cell lines but no significant activity was observed in those lines.
