E64FC26 是蛋白质二硫键异构酶(PDI)家族的一种有效的泛抑制剂,对 PDIA1、PDIA3、PDIA4、TXNDC5 和 PDIA6 的IC50分别为 1.9、20.9、25.9、16.3 和 25.4 μM。E64FC26 显示抗骨髓瘤活性。
生物活性 | E64FC26 is a potent pan-inhibitor of theprotein disulfide isomerase (PDI)family, withIC50s of 1.9, 20.9, 25.9, 16.3, and 25.4 μM against PDIA1, PDIA3, PDIA4, TXNDC5, and PDIA6, respectively. E64FC26 shows anti-myeloma activity[1]. |
体外研究 (In Vitro) | E64FC26 (0.01-100 μM; 24 hours) shows anti-MM activity , with an EC50of 0.59 μM[1].
E64FC26 is more cytotoxic against a genetically diverse panel of multiple myeloma (MM) cell lines (KMS11, OPM2, MM.1S BzR, MM.1S, SA-13, U266 BzR, ANBL6, KMS12PE, U266, 8226 DxR, 8226 BzR, KMS12BM, H929,8226 cells) when compared to non-malignant cells[1].
Cell Viability Assay[1] Cell Line: | MM.1S BzR cells | Concentration: | 0.01, 0.1, 1, 10, 100 μM | Incubation Time: | 24 hours | Result: | Showed anti-MM activity , with an EC50of 0.59 μM. |

体内研究 (In Vivo) | E64FC26 (2 mg/ kg; i.p.; three days a week for 7days) shows anti-MM effect in NSG mice model, and increases median survival by 2 weeks[1]. The combination of E64FC26 and Bortezomib produced the greatest improvement in survival, extending the median survival by 20 days[1]. Pharmacokinetic of E64FC26 was measured in CD-1 mice. E64FC26 was administered i.v. (2 mg/kg; gray tracing) or p.o. (5 mg/ kg; blue tracing) and plasma drug concentrations were measured over a 24 h period. In CD-1 mice demonstrated adequate oral bioavailabilty of 34% with systemic exposure approaching a maximum concentration (Cmax) of 400 nM after a single oral dose of 5 mg/kg with a terminal half-life of 9.5 h[1]. Vk*MYC transgenic mice are treated with E64FC26 (2 mg/kg, i.p., 3 days/week) for two consecutive weeks. E64FC26 treatment induces an immediate anti-MM response, decreasing serum M-protein in all mice by an average of 33 ± 7.9%[1].
Animal Model: | NOD-SCID IL2Rγ-/- (NSG) mice (bearing MM.1S cells)[1] | Dosage: | 2 mg/ kg | Administration: | i.p.; three days a week for 7days | Result: | Showed a clear anti-MM effect in this model also, increasing median survival by 2 weeks. |
