Abstract
The activities of the pyrrolizines, compounds 1 and 2, and the pyrroles, compounds 4 and 5, are reported in nude mouse-grown HT-29 human adenocarcinoma of the colon, DO 1 human oat carcinoma of the lung, and CL 1 human duct cell carcinoma of the breast (coded as CX-1, LX-1 and MX-1, respectively, by the National Cancer Institute [USA]). Compounds 2 and 4 were active against all 3 experimental tumors. Both compounds produced significant tumor regression in the human breast tumor xenograft and compound 4 caused tumor regression in the human lung tumor xenograft.
