Pralatrexate, (S)- is a folate analog dihydrofolate reductase (DHFR) inhibitor exhibiting high affinity for reduced folate carrier-1 (RFC-1) with antineoplastic and immunosuppressive activities. Pralatrexate selectively enters cells expressing RFC-1; intr
Pralatrexate, (R)- is a folate analog dihydrofolate reductase (DHFR) inhibitor exhibiting high affinity for reduced folate carrier-1 (RFC-1) with antineoplastic and immunosuppressive activities. Pralatrexate selectively enters cells expressing RFC-1; intr
Antifolate C1 is an inhibitor of de novo purine biosynthesis. Antifolate C1 has selectivity for cellular uptake by high affinity folate receptors and the proton-coupled folate transporter (PCFT) over the reduced folate carrier (RFC).
