PROTAC IDO1 Degrader-1 是第一个强效的IDO1(indoleamine 2,3-dioxygenase 1) 降解剂,它将IDO1劫持到CereblonE3连接酶上,最终实现泛素化和降解 (DC50=2.84 μM)。PROTAC-IDO1降解剂-1适度提高H-ER2-CAR-T细胞的杀伤活性。
生物活性 | PROTACIDO1 Degrader-1 is the first potentIDO1(indoleamine 2,3-dioxygenase1) degrader that hijacksIDO1toCereblonE3 ligase to introduceIDO1into UPS and eventually achieve ubiquitination and degradation (DC50=2.84 μM).PROTACIDO1 Degrader-1 moderately improves the tumor-killing activity of H ER2 CAR-T cells[1]. |

体外研究 (In Vitro) | PROTAC IDO1 Degrader-1 (compound 2c) (10 μM; 24 hours) notably decreases IDO1 level induced by IFN-γ[1]. PROTAC IDO1 Degrader-1 and IFN-γ (5 ng/mL) are incubated with HeLa cells for 24 h, and a significant dose-dependent degradation is observed. PROTAC IDO1 Degrader-1 combined with chimeric antigen receptor-modified T (CAR-T) cells can improve the tumor-killing activity of HER-2 CAR-T cells[1]. PROTAC IDO1 Degrader-1 induces significant and persistent degradation of IDO1 with maximum degradation (dmax) of 93% in HeLa cells[1].
