Synthesis and Structure−Activity Relationships of a Novel Series of Tricyclic Dihydropyridine-Based KATP Openers That Potently Inhibit Bladder Contractions in Vitro
摘要:
Structure-activity relationships were investigated on a novel series of tricyclic dihydropyridine-containing K-ATP openers. This diverse group of analogues, comprising a variety of heterocyclic rings fused to the dihydropyridine nucleus, was designed to determine the influence on activity of hydrogen-bond-donating and -accepting groups and their stereochemical disposition. Compounds were evaluated for K-ATP activity in guinea pig bladder cells using a fluorescence-based membrane potential assay and in a pig bladder strip assay. The inhibition of spontaneous bladder contractions in vitro was also examined for a subset of compounds. All compounds studied showed greater potency to inhibit spontaneous bladder contractions relative to their potencies to inhibit contractions elicited by electrical stimulation.

A variety of 5-mono- and 5,6-disubstituted 1,4-dihydro-4-oxonicotinates were prepared by a novel pyridine synthesis which involves thermal cyclisation of enaminomethylenemalonates 9. The intermediates 9 were readily prepared through a few steps from commercially available starting materials.
