PACMA 31 is an irreversible, orally active protein disulfide isomerase (PDI) inhibitor with an IC50 of 10 μM. PACMA 31 forms a covalent bond with the active site cysteines of PDI. PACMA 31 shows tumor targeting ability and significantly suppresses ovarian tumor growth without causing toxicity to normal tissues.
IC50&Target
IC50: 10 μM (protein disulfide isomerase)
体外研究
PACMA 31 (0-10 μM; 24 hours) significantly inhibits colony formation in OVCAR-8 cells in a dose-dependent manner.
体内研究
PACMA 31 (20-200 mg/kg; i.p.; daily for 62 days) suppresses tumor growth in human ovarian cancer mouse xenografts .
Animal Model:
Athymic mice (bearing OVCAR-8 cells)
Dosage:
20-200 mg/kg
Administration:
I.p., per day for the first 3 wk with 5-d on and 2-d off treatment cycles, and dose was escalated to 40 mg/kg per day for the next 7 d; p.o., the initial dose of 20 mg/kg per day was gradually increased by 20 mg/kg per day with each dose for 3 d before it was orally dosed at 200 mg/kg per day for an additional 32 d, increasing the dose from 20 to 200 mg/kg
Result:
Compared with the control group, i.p. or per os administration of PACMA 31 significantly inhibited tumor growth by 85% and 65% at day 62, respectively.
