GPR84 is a putative medium-chain fatty acid receptor that is implicated in regulation of inflammation and fibrogenesis. Studies have indicated that GPR84 agonists may have therapeutic potential in diseases such as Alzheimer’s disease, atherosclerosis, and cancer, but there is a lack of quality tool compounds to explore this potential. The fatty acid analogue LY237 (4a) is the most potent GPR84 agonist
GPR84 是一种假定的中链脂肪酸受体,与炎症和纤维形成的调节有关。研究表明,GPR84 激动剂可能对阿尔茨海默病、动脉粥样硬化和癌症等疾病具有治疗潜力,但缺乏优质的工具化合物来探索这种潜力。脂肪酸类似物 LY237 ( 4a ) 是迄今为止公开的最有效的 GPR84 激动剂,但具有不利的理化性质。我们在此介绍4a的 SAR 研究。鉴定出几种高效激动剂,EC 50低至 28 pM,SAR 通常与基于结构的建模非常一致。环和极性基团的正确掺入导致 TUG-2099 ( 4s ) 和 TUG-2208 ( 42a ) 的鉴定,这两种高效 GPR84 激动剂具有降低的亲脂性以及良好至优异的溶解度、体外渗透性和微粒体稳定性,这将成为探索 GPR84 药理学和治疗前景的有价值的工具。
