A series of arylthioureas (1), aromatic aldehyde thiosemicarbazones (2) and 5-aryl-2-furfuraldehyde thiosemicarbazones (3) were condensed with 2,4-dichloro-5-fluorophenacyl bromide to yield respective arylaminothiazoles, arylidene/5-aryl-2-furfurylidene hydrazinothiazoles (4). The newly synthesized compounds were characterized by IR, 1H-NMR and mass spectral studies. These compounds were also screened

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。
Synthesis of Thiazolone Derivatives as Novel Soybean 15-LOX Inhibitors
Background: Thiazole derivatives are known as important sulfur containing heterocycles
which are present in a wide range of biologically active natural products.
Methods: A series of thiazolone derivatives were synthesized and evaluated for their soybean 15-LOX
inhibitory activity. The title compounds were prepared by the reaction of 2-arylthiazol-4(5H)-ones and
different aromatic aldehydes. All compounds were characterized and evaluated against soybean 15-LOX.
Results: Among the synthesized thiazolone derivatives, 5-(4-methoxybenzylidene)-2-((2-methoxyphenyl)
amino)thiazol-4(5H)-one (3l) was found to be the most active compound comparing with quercetin as the
reference drug.
Conclusion: It seems that prepared thiazolones having methoxy groups both on aryl and aminoaryl
moieties can be considered for further drug discovery research.
