Sphingosinekinases (SphK1, SphK2) are main regulators of sphingosine-1-phosphate (S1P), which is a pleiotropic lipid mediator involved in numerous physiological and pathophysiological functions. SphKs are targets for novel anti-cancer and anti-inflammatory agents that can promote cell apoptosis and modulate autoimmune diseases. Herein, we describe the design, synthesis and evaluation of an aminothiazole
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。

Provided herein are novel heteroaryl compounds, compositions comprising the compounds, and methods of treatment or prevention comprising administration of the compounds. The compounds are effective in the targeting of cells defective in the von Hippel-Lindau gene and in inducing autophagic cell death. The methods are directed to treating or preventing diseases such as cancer, and in particular cancers resulting from von Hippel-Lindau disease. The compounds of the invention may be administered in combination with another therapeutic agent.

N,N,N″-Trisubstituted guanidines (most of them N″-aryl-N-azacycloalkanecarboximidamides) are prepared in generally good yields by S-methylation of monosubstituted thioureas with methyl iodide in methanol or acetone and reaction of the resultant methyl carbamimidothioate hydroiodides with secondary amines in boiling tert-butyl alcohol or acetonitrile.

The synthesis of a series of (R)-3-[2-(2-amino)phenethyl]-1-(2,6-difluorobenzyl)-6-methyluracils containing a substituted thiophene or thiazole at C-5 is described. SAR around C-5 of the uracil led to the discovery that a 2-thienyl or (2-phenyl)thiazol-4-yl group is required for optimal receptor binding. The best compound from the series had a binding affinity of 2 nM (K(i)) for the human GnRH receptor
