Edatrexate

Edatrexate (CGP 30694), as known as 10-Ethyl-10-deazaaminopterin, is Methotrexate (HY-14519) analog, exhibits antitumor activity against MTX-resistant tumors. Edatrexate is an antifolate antimetabolite, can be used for reasearch of non-small-cell lung cancer, breast cancer, non-Hodgkin's lymphoma, and cancer of the head and neck[1][2].

Edatrexate (0.14 g/kg and 0.21 g/kg; i.p.; twice weekly×3 or weekly×3) exerts potent efficacy against advanced metastatic disease in tumor-bearing mice, better than MTX[1]. Animal Model: Murine models of advanced metastatic disease (including E0771 mammary adenocarcinoma, T241 fibrosarcoma, Lewis lung carcinoma, B16 melanoma, or C38 colon carcinoma)[2] Dosage: 0.14 g/kg and 0.21 g/kg Administration: Intraperitoneal injection; 0.14 g/kg twice weekly for 3 weeks and 0.21 g/kg weekly for 3 weeks; added Ca leucovorin (LCV) 16, 20, 24 h after Edatrexate treatment Result: Increased survival of tumor-bearing mice. Showed markedly therapeutic effectiveness against advanced metastatic disease in high-dose regimen with delayed LCV rescue.
