Core exploration in optimization of chemokine receptor CCR4 antagonists
摘要:
The design, synthesis, and SAR studies of 'core' variations led to identification of novel, selective, and potent small molecule antagonist (22) of the CC chemokine receptor-4 (CCR4) with improved in vitro activity and liability profile. Compound 22 was efficacious in a murine allergic inflammation model (ED50 similar to 10 mg/kg). (c) 2006 Elsevier Ltd. All rights reserved.

An efficient oxidative functionalization of purine-like substrates with (thio)ethers or methylarenes under mild conditions is described. Using I2 as the catalyst, and TBHP as the oxidant, this protocol provides a valuable synthetic tool for the assembly of a wide range of 9-alkyl(benzyl)purin-8-one derivatives with high atom- and step-economy and exceptional functional group tolerance.

The Length and Flexibility of the 2-Substituent of 9-Ethyladenine Derivatives Modulate Affinity and Selectivity for the Human A<sub>2A</sub>Adenosine Receptor
that the insertion of substituents at various positions on adenine leads to A2A AR antagonists with affinity in the micromolar to nanomolar range. In this work, a series of 9‐ethyladenine derivatives bearing phenylalkylamino, phenylakyloxy or phenylakylthio groups of different lengths at the 2‐position were synthesised and tested against the human adenosine receptors. The derivatives showed sub‐micromolar
A 2A腺苷受体(A 2A AR)是开发用于治疗中枢神经系统疾病的药理学工具的关键目标。先前的研究表明,在腺嘌呤的不同位置插入取代基会导致A 2A具有在微摩尔至纳摩尔范围内的亲和力的AR拮抗剂。在这项工作中,合成了一系列在2位带有不同长度的苯基烷基氨基,苯基烷基氧基或苯基烷基硫基的9-乙基腺嘌呤衍生物,并针对人腺苷受体进行了测试。衍生物对这些膜蛋白表现出亚微摩尔的亲和力。在8位上进一步引入溴原子的作用是提高对所有AR的亲和力和选择性,并导致能够以低纳摩尔水平与A 2A AR亚型结合的化合物。功能研究证实,新的腺嘌呤衍生物具有A 2A的作用具有最大抑制浓度值在纳摩尔范围内的AR拮抗剂。分子建模研究提供了这些化合物在A 2A AR上可能的结合模式的描述,并解释了该AR亚型的亲和力数据。
