The hematopoietic prostaglandin D2 synthase has a proinflammatory effect in a range of diseases, including allergic asthma, where its product prostaglandin D2 (PGD2) has a role in regulating many of the hallmark disease characteristics. Here we describe the development and characterization of a novel series of hematopoietic prostaglandin D2 synthase inhibitors with potency similar to that of known
造血前列腺素D 2合酶在包括过敏性哮喘在内的多种疾病中具有促炎作用,其中其产物前列腺素D 2(PGD 2)在调节许多标志性疾病特征中起作用。在这里,我们描述了一系列新型造血前列腺素D 2合酶抑制剂的开发和表征,其功效与已知抑制剂相似。化合物N-苯甲酰基-5-(3-羟苯基)噻吩-2-羧酰胺(化合物8)和N-(1-氨基-1-氧代-3-苯基丙-2-基)-6-(噻吩-2-基烟酰胺(化合物34)在抑制纯化的酶方面表现出较低的微摩尔效价,而在小鼠原代骨髓来源的巨噬细胞和人巨核细胞系MEG-01S中,只有34种减少的Toll样受体(TLR)诱导的PGD 2产生。重要的是,34证实了抑制PGD的更大的选择性2合成与该位于PGH的下游的其它类花生酸2(PGE 2和前列腺环素(6-酮基PGF的标志物1α)和血栓素(TXB 2))相比,已知的抑制剂HQL -79(化合物1)和2-苯基-5-(1 H-吡唑-3-基
