Evaluation of the cyclopentane-1,2-dione as a potential bio-isostere of the carboxylic acid functional group
摘要:
Cycloalkylpolyones hold promise in drug design as carboxylic acid bio-isosteres. To investigate cyclopentane-1,2-diones as potential surrogates of the carboxylic acid functional group, the acidity, tautomerism, and geometry of hydrogen bonding of representative compounds were evaluated. Prototypic derivatives of the known thromboxane Ay prostanoid (TP) receptor antagonist, 3-(3-(2-((4-chlorophenyl)-sulfon-amido)-ethyl)phenyl)propanoic acid, in which the carboxylic acid moiety is replaced by the cyclopentane-1,2-dione unit, were synthesized and evaluated as TP receptor antagonists. Cyclopentane-1,2-dione derivative 9 was found to be a potent TP receptor antagonist with an IC50 value comparable to that of the parent carboxylic acid. These results indicate that the cyclopentane-1,2-dione may be a potentially useful carbox ylic acid bio-isostere. (C) 2014 Elsevier Ltd. All rights reserved.

The invention relates to pyridinyl nicotinic acetylcholine receptor ligands, compositions comprising an effective amount of a pyridinyl nicotinic acetylcholine receptor ligand and methods to treat or prevent a condition, such as depression and nicotine dependence, comprising administering to an animal in need thereof an effective amount of a pyridinyl nicotinic acetylcholine receptor ligand.
this report, the combination of masked inorganic sulfur and dimethyl carbonate was designed to achieve thiomethylated cross coupling of aryl chlorides. Remarkably, this powerful strategy realized thiomethylation of nucleosides bearing unprotected ribose, chloride-containing pharmaceuticals with late-stage coupling, and herbicides possessing multiple heteroatoms and steric hindrance. Moreover, this protocol
