reversible thiourea inhibitors of ABHD12 that culminated in the identification of DO264 as a potent, selective, and in vivo active ABHD12 inhibitor. We also show that DO264, but not a structurally related inactive control probe (S)-DO271, augments inflammatory cytokine production from human THP-1 macrophage cells. The in vitro and in vivo properties of DO264 designate this compound as a suitable chemical probe
ABHD12是一种膜结合水解酶,作用于免疫调节脂质的溶血磷脂酰丝氨酸(lyso-PS)和溶血磷脂酰肌醇(lyso-PI)类。人类和小鼠的遗传研究指出,ABHD12-(lyso)-PS / PI途径在调节中枢神经系统和周围神经的(神经)免疫功能中起着关键作用。ABHD12的选择性抑制剂将提供有价值的药理探针,以补充ABHD12调控的(溶血)-PS / PI代谢和信号传导的遗传模型。在这里,我们提供了对发现和基于活性的蛋白质谱分析(ABPP)指导的ABHD12可逆硫脲抑制剂优化的详细描述,该抑制剂最终将DO264鉴定为有效,选择性和体内活性ABHD12抑制剂。我们还证明了DO264,但不是结构相关的失活对照探针(S)-DO271,却增加了人THP-1巨噬细胞的炎性细胞因子产生。DO264的体外和体内特性将该化合物指定为研究ABHD12-(lyso)-PS / PI途径生物学功能的合适化学探针。
