CGRP, known as the most potent vasodilator substance, plays an important role in hypertension initiation and development. TRPV1 and TRPA1 are critical in promoting the synthesis and release of CGRP, thereby regulating the cardiovascular tone. Rutaecarpine exhibits potent vasodilator and hypertensive effects by stimulating CGRP synthesis and release via activation of TRPV1. And NO has been shown to react with H2S in vivo to form HNO, thereby activating HNO-TRPA1-CGRP pathway. Inspired by combination therapy, 11 rutaecarpine-furoxan hybrids were designed, synthesized and evaluated. The results d...
