Chemical Structure
Talotrexin
Synonym(s): PT523
- CAS No.: 113857-87-7
- Formula:C27H27N9O6
- Molecular Weight:573.56
IUPAC Name: (S)-2-((4-carboxy-4-(4-(((2,4-diaminopteridin-6-yl)methyl)amino)benzamido)butyl)carbamoyl)benzoic acid
InChIKey: NYQPLPNEESYGNO-IBGZPJMESA-N
SMILES: NC1=NC(N)=NC2=C1N=C(CNC3=CC=C(C=C3)C(N[C@H](C(O)=O)CCCNC(C4=C(C=CC=C4)C(O)=O)=O)=O)C=N2
Biological Activity: 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].
