Parallel synthesis of N-biaryl quinolone carboxylic acids as selective M1 positive allosteric modulators
摘要:
An iterative analog library synthesis approach was employed in the exploration of a quinolone carboxylic acid series of selective M-1 positive allosteric modulators, and strategies for improving potency and plasma free fraction were identified. (C) 2009 Elsevier Ltd. All rights reserved.
Replacement of a phenyl ring with N-linked heterocycles in a series of quinolone carboxylic acid M-1 positive allosteric modulators was investigated. In particular, a pyrazole derivative exhibited improvements in potency, free fraction, and CNS exposure. (C) 2010 Elsevier Ltd. All rights reserved.
