Plasmodium demands identification of new drugs with novel chemotypes and mechanisms of action. As a follow up to our evaluation of 4-aryl-N-benzylpyrrolidine-3-carboxamides as novel pyrrolidine-based antimalarial agents, we describe herein the structure–activity relationships of the reversed amide homologues 2-aryl-N-(4-arylpyrrolidin-3-yl)acetamides. Unlike their carboxamide homologues, acetamide pyrrolidines
疟疾是由疟原虫寄生虫感染引起的,每年造成数十万人死亡。疟原虫的新抗药性菌株的出现要求鉴定具有新化学型和作用机理的新药物。作为我们对4-芳基-N-苄基吡咯烷-3-羧酰胺作为新型吡咯烷基抗疟剂的评估的后续措施,我们在此描述了反向酰胺同系物2-芳基-N-(4-芳基吡咯烷酮)的结构-活性关系-3-基)乙酰胺。不同于其酰胺酰胺同系物,乙酰胺吡咯烷不需要第三手性中心即可成为P的有效抑制剂。恶性疟并且在疟疾的小鼠模型中具有良好的药代动力学特性和改善的口服功效。化合物(-)-32a(CWHM-1552)在恶性疟原虫3D7分析中的体外IC 50为51 nM ,体内ED 90 <10 mg / kg / day和ED 99为30 mg / kg /鼠P. chabaudi模型中的一天。值得注意的是,此乙酰胺系列(3 S,4 R)与同源羧酰胺系列测定的结果相反。此类先导化合物对hERG通道具有适度的亲和力,并抑制CYP
Novel Benzoxazole 2,4-Thiazolidinediones as Potent Hypoglycemic Agents. Synthesis and Structure-Activity Relationships.
benzoxazole 2,4-thiazolidinediones was synthesized and evaluated for hypoglycemicactivity in genetically obese and diabetic yellow KK mice. 2-Arylmethyl- and 2-(heteroarylmethyl)benzoxazole derivatives showed far more potent activity than known 2,4-thiazolidinedione derivatives such as ciglitazone, troglitazone and pioglitazone. A facile synthesis of benzoxazole 2,4-thiazolidinediones was also established using

The invention relates to naphthalene derivatives as well as their pharmaceutically acceptable salts. The invention further relates to a process for the preparation of such compounds. The compounds of the invention are glycine B antagonists and are therefore useful for the control and prevention of various disorders, including neurological disorders.
Discovery of orexin 2 receptor selective and dual orexin receptor agonists based on the tetralin structure: Switching of receptor selectivity by chirality on the tetralin ring
orientation of the amide side chain against the tetralin scaffold (S-configuration) would be selective for OX2R activation, and the downward orientation (R-configuration) would be significant for dual agonist activity. To our best knowledge, there have been no reports thus far that the stereochemistry of one carbon center on the agonist structure regulates the orexin receptor selectivity. Our results would
基于萘型食欲素受体激动剂5的推定结合模式设计和合成了一系列新型1-氨基四氢化萘衍生物,并评估了它们对食欲素受体的激动剂活性。在1-氨基-四氢化萘骨架上引入N-甲基-(3-甲氧基苯基)乙酰胺单元显着增强了激动剂的效力。6的不对称合成表明具有 ( S )-1-氨基-四氢化萘骨架的(–)- 6显示出 OX 2 R 选择性激动剂活性( OX 2 R、OX 1 R/OX 2 R的 EC 50 = 2.69 nM = 461) 但它的对映体 ( R)-(+)- 6显示出有效的 OX 1/2 R 双激动剂活性(OX 1 R 的 EC 50 = 13.5 nM,OX 2 R 的 0.579 nM ,OX 1 R/OX 2 R = 23.3)。这些结果表明,酰胺侧链对四氢化萘支架(S构型)的向上取向对 OX 2 R 激活具有选择性,而向下取向(R-配置)对于双重激动剂活性将是重要的。据我们所知,到目前为
