PACMA 31 是一种不可逆的口服活性蛋白二硫化物异构酶(PDI)抑制剂,IC50为 10μM,PACMA 31 与 PDI 的活性部位半胱氨酸形成共价键。PACMA 31 具有肿瘤靶向性,能显著抑制卵巢肿瘤生长,对正常组织无毒性。
生物活性 | PACMA 31 is an irreversible, orally activeprotein disulfide isomerase (PDI)inhibitor with anIC50of 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] |
体外研究 (In Vitro) | PACMA 31 (0-10 μM; 24 hours) significantly inhibits colony formation in OVCAR-8 cells in a dose-dependent manner[1].
|
体内研究 (In Vivo) | PACMA 31 (20-200 mg/kg; i.p.; daily for 62 days) suppresses tumor growth in human ovarian cancer mouse xenografts[1].
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. |
