Problems solved by technology

A 2-helical calcium-binding motif domain is present at the N-terminus of TRPA1, but the domain's role is unclear
At present, there are few domestic studies, but foreign pharmaceutical companies have developed a series of pyrimidinedione TRPA1 inhibitors, and the TRPA1 channel has also become a research hotspot for new analgesics

Description

technical field [0001] The invention relates to the field of medicinal chemistry, more specifically to diphenylmethane drugs and their application in inhibiting the transient receptor potential channel protein TRPA1. Background technique [0002] Transient receptor potential channel (Transient receptor potential, TRP) is a kind of protein superfamily composed of important cation channels existing on the cell membrane. It was first discovered by Minke et al. when studying the visual transmission system of Drosophila. Subsequent studies have discovered a series of TRP family channel members. According to the sequence homology of about 30 TRP channels found in mammals, they are divided into six subfamilies, namely TRPC, TRPV, TRPM, TRPML, TRPA and TRPP. Both the C-terminal and N-terminal of the TRP channel are located in the cell membrane, and contain six transmembrane domains of S1-S6. The ligand-binding reaction sites on domains S1-S4 may be gated pores, but the S4 domain l...
