Summary
PACMA 31 is an irreversible, orally active protein disulfide isomerase (PDI) inhibitor with an IC 50 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 [1] .
IC50 & Target
IC50: 10 μM (protein disulfide isomerase) [1]
In Vitro
PACMA 31 (0-10 μM; 24 hours) significantly inhibits colony formation in OVCAR-8 cells in a dose-dependent manner [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
PACMA 31 (20-200 mg/kg; i.p.; daily for 62 days) suppresses tumor growth in human ovarian cancer mouse xenografts [1] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
| Animal Model: | Athymic mice (bearing OVCAR-8 cells) [1] |
| 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. |
