has been found to be a potentinhibitor of both the human constitutive and inducible isoforms of nitricoxidesynthase. A series of substituted N-phenylisothiourea analogues was synthesized to investigate the structure-activity relationship of this class of inhibitor. Each analogue was evaluated for human isoform selectivity. One analogue, S-ethyl N-[4-(trifluoromethyl)phenyl]isothiourea (39), exhibited

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。

An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N′-benzoylthioureas with 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.
A series of fused bicyclic 2-aminothiazolyl compounds were synthesized and evaluated for their synergistic effects with polymyxin B (PB) against Klebsiella pneumoniae (SIPI-KPN-1712).

chlorine and t-Bu group at the para-position in benzene ring plays an important role in the antitubercular activity of Series A. These substituents were fixed at this position in benzene ring and other groups such as Cl, Br, NO2 and OMe were introduced in the benzoyl ring, leading to the derivatives of Series B. In general, Series B was less cytotoxic than Series A, which indicates that the presence
