鞘氨醇激酶(SphK1,SphK2)是鞘氨醇-1-磷酸酯(S1P)的主要调节剂,鞘氨醇-1-磷酸酯是一种参与多种生理和病理生理功能的多效脂质介体。SphK是新型抗癌和抗炎剂的靶标,这些抗癌剂和抗炎剂可促进细胞凋亡并调节自身免疫性疾病。本文中,我们描述了氨基噻唑类SphK抑制剂的设计,合成和评估。通过使用已知的SKI-II支架进行一系列修饰来定义结构-活性关系,已经发现了有效的抑制剂。我们确定了N-(4-甲基噻唑-2-基)-(2,4'-bithiazol)-2'-胺(24,ST-1803 ; IC 50 值:7.3μM(SphK1),6.5μM(SphK2))有望成为进一步体内研究和结构开发的有希望的候选者。

Biological evaluation of N‐aryl‐4‐aryl‐1,3‐thiazole‐2‐amine derivatives was examined for anti‐inflammatory activity in in vitro and in vivo assays. The thiazole compounds showed direct inhibition of 5‐lipoxygenase (LOX) that is a key enzyme of leukotrienes synthesis and involved in the inflammation‐related diseases, including asthma and rheumatoid arthritis. To optimize biological activity, we synthesized 1

Valosin-containing protein (VCP; also known as p97) is a member of the AAA ATPase family with a central role in the ubiquitin-degradation of misfolded proteins. VCP also exhibits antiapoptotic function and metastasis via activation of nuclear factor kappa-B signaling pathway. We have discovered that 2-anilino-4-aryl-1,3-thiazoles are potent drug-like inhibitors of this enzyme. The identified compounds show low nanomolar VCP potency, demonstrate SAR trends, and show activity in a mechanism based cellular assay. This series of compounds represents the first steps towards a novel, small molecule VCP inhibitor as a cancer therapeutic. (C) 2010 Elsevier Ltd. All rights reserved.
