  Variation in the aromatic ring of cromakalim: antihypertensive activity of pyranopyridines and 6-alkyl-2H-1-benzopyrans

  摘要：

  The synthesis and antihypertensive activity in the spontaneously hypertensive rat of two new series of analogues related to cromakalim (1) are described. In the first series, where the benzopyran nucleus has been replaced by a pyranopyridine nucleus, the position of the nitrogen atom has been found to be critical for activity, and the most potent compounds are the pyrano[3,2-c]pyridines. In the second series, where the powerful electron-withdrawing cyano group of compound 1 has been replaced by alkyl and phenyl groups, the order of antihypertensive potency is ethyl, isopropyl, tert-butyl greater than propyl, cyclopentyl greater than methyl greater than phenyl.

  A series of 4-amido-3,4-dihydro-2H-1-benzopyran-3-ols and 4-amido-2H-1-benzopyrans related to the potassium channel activator cromakalim have been prepared and evaluated for their relaxant activity in guinea pig isolated tracheal spirals. Several analogues show enhanced relaxant activity relative to cromakalim in this preparation and the rank order of potency for those substituents investigated at C-6 was CF3 greater than CN greater than C2H5 greater than aza greater than or equal to CH3. One compound, trans-3,4-dihydro-2,2-dimethyl-4-(2-oxopiperidin-1-yl)-7-(trifluor omethyl)-2H- 1-benzopyran-3-ol (24), was resolved into its two enantiomers and the activity was shown to reside essentially in the (+)-isomer, adding further support to the suggestion that the smooth muscle receptor for these potassium channel activators is stereoselective.
