Introduction of 113857-87-7 :

Talotrexin (PT523), an analog of Aminopterin (HY-14518), is a nonpolyglutamatable classic antifolate. Talotrexin is a RFC (reduced folate carrier) specific inhibitor and selectively inhibits RFC transport. Talotrexin shows antitumor activity by targeting DHFR to inhibit tumor growth[1][2]. In Vitro: Talotrexin shows no significant PCFT or FRα inhibitory activity[1].
Talotrexin (1-1000 nM) inhibits proliferation of R1-11/Tet-on-RFC HeLa cells[2]. In Vivo: Talotrexin (0-35 mg/kg, IV injection, once weekly for 4 weeks) alone or combined with Paclitaxel (HY-B0015, 7.5 mg/kg) inhibits A549 tumor growth in mice[2].
