  Novel hybrids of natural isochroman-4-one bearing N-substituted isopropanolamine as potential antihypertensive candidates

  摘要：

  A series of novel hybrids of natural isochroman-4-one bearing isopropanolamine moiety were designed, synthesized and evaluated for their antihypertensive activity. It was found that compound IIId, prepared by hybridizing N-isopropyl substituted isopropanolamine functionality to a phenolic oxygen of isochroman-4-one, exhibited potent beta(1)-adrenoceptor blocking effect comparable to the well-known antihypertensive drug propranolol. Additionally, IIId significantly reduced the systolic and diastolic blood pressure in SHRs by over 40%, which was obviously stronger than the lead compounds 7,8-dihydroxy-3-methyl-isochroman-4-one (XJP) and its analogue XJP-B. Overall, IIId may be a promising antihypertensive candidate for further investigation. (C) 2013 Elsevier Ltd. All rights reserved.

  By coupling nitric oxide (NO)-donor moieties with a natural antihypertensive product (+/-)-7,8-dihydroxy3-methyl-isochroman-4-one [(+/-)-XJPI and its analogue (+/-)-XJP-B, a series of novel NO-releasing isochroman-4-one derivatives were designed and synthesized. The NO-releasing assay indicated that compounds Ia, Id, IIIb and IIIe released the maximum amount of NO. The maximum reductions of blood pressure of Ia, IIIb and IIIe in SHRs were nearly 40%, which was obviously superior to that of the lead compounds and comparable to that of reference drug captopril. These results suggested that NO-donor/natural product hybrids may provide a promising approach for the discovery of novel antihypertensive agents. (C) 2012 Elsevier Ltd. All rights reserved.
