生物活性:
ONX 0801 (BGC 945) trisodium is a thymidylate synthase (TS) inhibitor, targeted to α-folate receptor–overexpressing tumors.

体内研究:
BGC 945 (100 mg/kg, ip/iv injection) in the tumor had a longer half-life (28 hours) compared with other tissues.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.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.Animal Model:Mice (on the folate-free diet for 5 days were transplanted with tumor and the implants).
Dosage:100 mg/kg (Pharmacokinetic Analysis).
Administration:Single i.p. or iv injection.
Result:After i.p. injection, the compound was well absorbed from the peritoneal cavity. The plasma AUC was 50% higher for i.p. compared with i.v. administration and was also higher in spleen, kidney, and liver by this route. Tumor AUC was similar via either route.

体外研究:
ONX 0801 (BGC 945) is designed to further reduce toxicity by more effectively targeting cancer cells that overexpress the α-FR.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.
