Description

Deuterated piperidine amide CGRP inhibitor medicine and application thereof
Technical Field
The invention belongs to the field of biological medicine, and in particular relates to a deuterated piperidine amide CGRP inhibitor medicine and application thereof.
Background
Migraine (migrain) is a common neurological disorder that can cause severe pain on one or both sides of the head, and the associated symptoms include nausea, vomiting, sensitivity to light, sound or smell. If left untreated, a single episode may last from 4 to 72 hours and may repeatedly occur, severely affecting the patient's work and life. The pathogenesis of migraine is not well defined, but is affected by environmental and genetic factors and is closely related to family history. Over 10 million people worldwide have migraine, which is one of the most serious cases of medical disability by the world health organization.
One leading hypothesis currently regarding the pathogenic mechanisms of migraine is based on the activation of the trigeminal vascular system. Several neuropeptides are involved in this activation, with Calcitonin Gene Related Peptide (CGRP) playing a key role. CGRP exerts a variety of different biological effects through the peripheral and Central Nervous System (CNS). Functional CGRP-receptor (CGRP-R) complexes have been well characterized and new therapeutic approaches target CGRP itself and its receptor.
For the medicine for treating migraine with good treatment effect, the medicines which are selected in the market are not many, so that the clinical requirement is high, and the search for a novel CGRP inhibitor for treating migraine is also an urgent task.
