ONX 0801 trisodium  (Synonyms: BGC 945 trisodium; Idetrexed trisodium; CB 300945 trisodium)

ONX 0801 (BGC 945) trisodium is a thymidylate synthase (TS) inhibitor, targeted to α-folate receptor–overexpressing tumors^[1][2].

ONX 0801 (BGC 945) is designed to further reduce toxicity by more effectively targeting cancer cells that overexpress the α-FR^[1].
ONX 0801 (BGC 945) exhibits IC₅₀ values of of 6.6 μM, 1.1 nM, 3.3 nM, 90 nM and 0.32 μM in A431, A431-FBP, KB, IGROV-1 and JEG-3 cells^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

BGC 945 (100 mg/kg, ip/iv injection) in the tumor had a longer half-life (28 hours) compared with other tissues^[2].
BGC 945 (100 mg/kg daily for 16 days) does not lead to body weight loss, macroscopic signs of toxicity to the major organs, or a change in renal function^[2].
BGC 945 at 100mg/kg induces a 5-20-fold increase in tumor dUrd at 4-72h without increases in the plasma, consistent with tumor targeting^[2].
