In an extension of our prior studies in murine tumor models, we examined two new folate analogs in the 10-deaza-aminopterin series for antitumor activity against a group of human tumor xenografts in nude mice. In all three xenograft models studied, MX-1 mammary carcinoma, LX-1 lung carcinoma, and CX-1 colon carcinoma, 10-deaza-aminopterin was minimally active, while methotrexate was inactive. In contrast, against the MX-1 and LX-1 tumors, 10-ethyl, 10-deaza-aminopterin at or near the LD10 dose… CONTINUE READING
