  Synthesis of N-benzyl- and N-phenyl-2-amino-4,5-dihydrothiazoles and thioureas and evaluation as modulators of the isoforms of nitric oxide synthase

  摘要：

  Inhibition of the isoforms of nitric oxide synthase (NOS) has important applications in therapy of several diseases, including cancer. Using 1400W [N-(3-aminomethylbenzyl)acetamidme], thiocitrulline and N-delta-(4,5-dihydrothiazol-2-yl)ornithine as lead compounds, series of N-benzyl- and N-phenyl-2-amino-4,5-dihydrothiazoles and thioureas were designed as inhibitors of NOS. Ring-substituted benzyl and phenyl isothiocyanates were synthesised by condensation of the corresponding amines with thiophosgene and addition of ammonia gave the corresponding thioureas in high yields. The substituted 2-amino-4,5-dihydrothiazoles were approached by two routes. Treatment of simple benzylamines with 2-methylthio-4,5-dihydrothiazole at 180degreesC afforded the corresponding 2-benzylamino-4,5-dihydrothiazoles. For less nucleophilic amines and those carrying more thermally labile substituents, the 4,5-dihydrothiazoles were approached by acid-catalysed cyclisation of N-(2-hydroxyethyl)thioureas. This cyclisation was shown to proceed by an S(N)2-like process. Modest inhibitory activity was shown by most of the thioureas and 4,5-dihydrothiazoles, with N-(3-aminomethylphenyl)thiourea (IC50 = 13 muM vs rat neuronal NOS and IC50 = 23 muM vs rat inducible NOS) and 2-(3-aminomethylphenylamino)-4,5-dihydrothiazole (IC50 - 13 muM vs rat neuronal NOS and IC50 = 19 muM vs human inducible NOS) being the most potent. Several thioureas and 4,5-dihydrothiazoles were found to stimulate the activity of human inducible NOS in a time-dependent manner. (C) 2003 Elsevier Ltd. All rights reserved.

  报道了一种以分子多样性为导向的方法，用于制备定义明确的聚阳离子两亲环糊精（paCD）作为基因传递系统。合成策略利用CD圆环上伯羟基和仲羟基的不同反应性，分别用阳离子元素和亲脂性尾区区域选择性地修饰每个边缘。电荷密度和疏水-亲水平衡都可以在高度对称的结构中进行微调，这使人联想到两种最突出的非病毒基因载体阳离子脂质和阳离子聚合物。paCD的单分散性质和合成方案的模块性特别适合于结构-活性关系研究。凝胶电泳显示，在存在质粒DNA（pDNA）的情况下，paCD能够自组装，从而提供70-150 nm的均匀，稳定的纳米颗粒（CDplex），可以完全保护pDNA免受环境污染。在没有血清和存在血清的情况下，已在BNL-CL2和COS-7细胞系上体外研究了所得CDplex的转染效率，发现其与体系结构特征密切相关。面部两亲性以及聚阴离子DNA链协同和可逆络合的阳离子和氢键中心簇的存在对于获得高转基因表达水平和

  In order to study supramolecular architectures built from unnatural oligomeric and polymeric structures, one must first have an efficient synthetic strategy to produce them. Oligomers built from thiourea groups should form complex secondary and tertiary structures due to the hydrogen-bonding capabilities of the thioureas. Herein, both solution and solid phase synthetic procedures that yield oligomeric thioureas are described. They rely on the coupling of an isothiocyanate with an amine to produce the thiourea linkage. The monomers are derived from simple diamines. Higher yields are achieved using the solid phase method due to the ability to easily monitor the extent of reaction, to use a large excess of reagent, and to perform purification after cleavage from the solid support. A variety of oligomers are given as examples. The procedure is quite general, should be easily extended to complex monomers, and will allow the investigation of intramolecular and intermolecular interactions.
• Effect of spacer geometry on oxoanion binding by bis- and tetrakis-thiourea hosts

  日期：2008.3

  Hosts with thiourea groups bind anions by formation of multiple hydrogen bonds. This contribution discusses how spacers linking two or four thiourea groups affect the host affinity and selectivity. While most of the bis-thioureas bind H2PO4- preferentially, the extent of selectivity over chloride, acetate, and H2AsO4- is determined by the size of the binding cavity. A tetrakis-thiourea is shown to exhibit a unique H2AsO4- selectivity, and the discrimination of chloride is enhanced by specific solvation in dimethyl sulfoxide. (c) 2008 Elsevier Ltd.
