α1-Adrenoceptor Agonists: The Identification of Novel α1A Subtype Selective 2′-Heteroaryl-2-(phenoxymethyl)imidazolines
摘要:
Novel 2'-heteroaryl-2-(phenoxymethyl)imidazolines have been identified as potent agonists of the cloned human alpha(1)-adrenoceptors in vitro. The nature of the 2'-heteroaryl group can have significant effects on the potency, efficacy, and subtype selectivity in this series. alpha(1A) Subtype selective agonists have been identified.

Herein we describe the design and synthesis of a series of pyridopyrazine-1,6-dione gamma-secretase modulators (GSMs) for Alzheimer's disease (AD) that achieve good alignment of potency, metabolic stability, and low MDR efflux ratios, while also maintaining favorable physicochemical properties. Specifically, incorporation of fluorine enabled design of metabolically less liable lipophilic alkyl substituents to increase potency without compromising the sp(3)-character. The lead compound 21 (PF-06442609) displayed a favorable rodent pharmacokinetic profile, and robust reductions of brain A beta 42 and A beta 40 were observed in a guinea pig time-course experiment.
