Neocryptolepine (5-methyl-5H-indolo[2,3-b] quinoline) analogs were synthesized and evaluated in vitro and in vivo for their effect versus Ehrlich ascites carcinoma (EAC). The analogs showed stronger cytotoxic activity against EAC cells than the reference drug. The in vivo evaluation of the target compounds against EAC-induced solid tumor in the female albino Swiss mice revealed a remarkable decrease in the tumor volume (TV) and hepatic lipid peroxidation. A noticeable increase of both superoxide dismutase (SOD) and catalase (CAT) levels was reported (p p < 0.001) with the elevation of the responsiveness of lymphocytes to phytohemagglutinin (PHA). These results indicate that these naturally-based neocryptolepine alkaloids exhibit marked antitumor activity in vivo and represent an important lead in the development of natural-based anticancer drugs.
