JQAD1 is a CRBN-dependent PROTAC that selectively targets EP300 for degradation. JQAD1 suppresses EP300 expression and the H3K27ac modification. JQAD1 induces apoptosis. JQAD1 can be used in research of cancer.

Solid
体外研究(In Vitro)
JQAD1在对照组 Kelly NB 细胞而不是 CRBN 敲除细胞中抑制 EP300 的表达,抑制 H3K27ac 修饰,并诱导凋亡。JQAD1 (0.5 or 1 μM; 6-96 h) 处理导致早期时间依赖性诱导亚 G1 峰,表明 Kelly 和 NGP细胞凋亡死亡。JQAD1 (1 μM; 12-36 h) 诱导 Kelly NB 细胞凋亡。JQAD1 (0.5 μM; 24 h) 处理的细胞表现出促凋亡的 BH3 效应物 BIM、BID 和 PUMA 以及促凋亡介质 BAX 及其抑制剂 BCL2 和 MCL1 的上调。JQAD1 (0.5 and 1 μM; 24 h) 破坏 MYCN 表达。JQAD1 (0.5 μM; 24 h) 导致染色质上 H3K27ac 缺失。JQAD1 (1.2 nM-20 μM; 5 days) 具有广泛的 CRBN 依赖的跨癌细胞系抗肿瘤活性。JQAD1 以时间依赖的方式诱导 EP300 降解,最早在 16 小时。 has not independently confirmed the accuracy of these methods.
