| Abstract: | CGRP receptor (CLR) is a B class GPCR that functions only when combined with RAMPs. CLR/RAMP1 has been regarded as a promising target for migraine treatment, as its antagonists have been proved to be effective recently. In the present study we designed and synthesized small molecular antagonists against CLR/RAMP1, resulting in a novel type of structure with acceptable high potency. The molecules were designed via virtual screening. Afterwards, a series of modification were conducted on the hit compounds, resulting in compound 8 as the best scored compound in docking, which was further validated in vitro by cell-based functional assay. |
