Synthesis and biological activities of novel aryl indole-2-carboxylic acid analogs as PPARγ partial agonists
摘要:
A series of novel aryl indole-2-carboxylic acids has been identified as potent selective PPAR gamma modulators. Their chemical synthesis and in vitro activities are discussed. Compound 5 was selected for in vivo testing in the db/db mouse model of type 2 diabetes and resulted in reduction of hyperglycemia at comparable plasma exposure when compared to rosiglitazone.

A series of new 10-methoxypyrazino[1,2-a]indoles has been prepared and shown to be 5HT(2C) receptor ligands. The studied compounds 10a-j were found to act as partial agonists at the 5HT(2C) receptor, binding with high affinity and moderate selectivity versus 5HT(1A) and 5HT(2A) receptors, but inducing only a submaximal increase in phosphoinositol formation. Compound 10j was demonstrated to be active in animal models of obsessive-compulsive disorder, depression and panic anxiety.

On the basis that meta-chlorophenylpiperazine (mCPP: 1) is a nonselective 5-HT2C agonist. that benz-fused tryptamines (e.g., 5) display enhanced 5-HT2 affinity, and that certain isotryptamines 3 reportedly bind with enhanced affinity and selectivity at 5-HT2C receptors, we prepared and examined a series of isotryptamine-related analogues as potentially selective 5-HT2C agonists. None of the compounds displayed selectivity for 5-HT2C versus 5-HT2A receptors. Detailed re-examination of a compound previously reported to display 100-fold 5-HT2C selectivity [i.e.. S(+)-5,6-aifluoro-alpha-methylisotryptamine] revealed that its selectivity versus 5-HT2A receptors was, at best. only 10-fold. (C) 2002 Elsevier Science Ltd. All rights reserved.
