  Thiophene systems. 14. Synthesis and antihypertensive activity of novel 7-(cyclic amido)-6-hydroxythieno[3,2-b]pyrans and related compounds as new potassium channel activators

  摘要：

  The synthesis and antihypertensive activity of novel 7-(cyclic amido)-6-hydroxy-5,5-di-methylthieno[3,2-b]pyrans and related compounds are described. The compounds were tested for oral antihypertensive activity in spontaneously hypertensive rats (SHR) and selected compounds were evaluated in vitro for increases in Rb-86 efflux in rabbit isolated mesenteric arteries. The effects on activity in SHR of lactam ring size, the presence of heteroatoms in the lactam ring, the relative stereochemistry at C-6 and C-7, and the substituents on the thiophene ring are examined. The best racemic compound in this series is 32, trans-5,6-dihydro-6-hydroxy-5,5-di-methyl-2-nitro-7-(2-oxopiperidin-1-yl)-5H-thieno[3,2-b]pyran, which is 10-fold more potent than cromakalim with an ED30 = 0.015 mg/kg in SHR. Compound 32 could be resolved and the antihypertensive activity determined to reside primarily in the (6S,7S)-(-)-enantiomer 41. Surprisingly, the elimination of water to give the enamides 50-52, thiophene isosteres of bimakalim, diminishes activity significantly.

  A process for the preparation of enantiomerically pure thienopyran derivatives of the formula ##STR1## is described. The thienopyran derivatives are relaxants of smooth muscle tone and as such are useful in vascular tissue for the treatment of hypertension disease, angina and other vascular disorders characterized by poor regional perfusion.
