  摘要：

  据报道一系列含有硝酸盐（ONO（2））作为一氧化氮（NO）-供体官能团的新型吡唑的合成。分析了它们在人全血中对COX-1和COX-2的抑制活性。我们的数据表明，吡唑环取代基在COX-2选择性抑制中起重要作用，因此发现环烷基吡唑（6b）是一种有效且选择性的COX-2抑制剂。在中心吡唑环（17b，23b，26b-1）的3位上的其他修饰增强了COX-2抑制能力。在合成的吡唑中，肟（23b）被确定为最有效的COX-2选择性抑制剂。因此，口服给药后在大鼠中进行了药理学分析，结果表明23b在角叉菜胶诱导的气袋模型中具有有效的抗炎活性，并且与背景阿司匹林一起给药时，胃毒性比标准COX-2抑制剂低。我们建议，NO供体COX-2选择性抑制剂的胃耐受性增强，有可能增加该药物类别的临床表现。

  Identification of potent pyrazole based APELIN receptor (APJ) agonists

  摘要：

  The apelinergic system comprises the apelin receptor and its cognate apelin and elabela peptide ligands of various lengths. This system has become an increasingly attractive target for pulmonary and cardiometabolic diseases. Small molecule regulators of this receptor with good drug-like properties are needed. Recently, we discovered a novel pyrazole based small molecule agonist 8 of the apelin receptor (EC50 = 21.5 mu M, K-i = 5.2 mu M) through focused screening which was further optimized to initial lead 9 (EC50 = 0.800 mu M, K-i = 1.3 mu M). In our efforts to synthesize more potent agonists and to explore the structural features important for apelin receptor agonism, we carried out structural modifications at N1 of the pyrazole core as well as the amino acid side-chain of 9. Systematic modifications at these two positions provided potent small molecule agonists exhibiting EC50 values of < 100 nM. Recruitment of beta-arrestin as a measure of desensitization potential of select compounds was also investigated. Functional selectivity was a feature of several compounds with a bias towards calcium mobilization over beta-arrestin recruitment. These compounds may be suitable as tools for in vivo studies of apelin receptor function.

  The synthesis of a series of novel pyrazoles containing a nitrate (ONO(2)) moiety as a nitric oxide (NO)-donor functionality is reported. Their COX-1 and COX-2 inhibitory activities in human whole blood are profiled. Our data demonstrate that pyrazole ring substituents play an important role in COX-2 selective inhibition, such that a cycloalkyl pyrazole (6b) was found to be a potent and selective COX-2
