Dehydrocorydaline(DHC) not only inhibits antibody-mediated allergic reactions but also influences cell-mediated allergic reactions, and the inhibitory effect of Corydalis Tuber on allergic reactions may be partially attributed to DHC.

DAGLβ-IN-1 is a universal intermediate for designing DAGL tailored activity-based probes, and is an inhibitor of diacylglycerol lipase-β (DAGLβ).

Selective, high affinity, non-competitive α1A adrenoceptor antagonist (Ki = 0.35 nM). Exhibits no significant activity against a range of other GPCRs, including α2A, β1 and β2 adrenoceptors. Antagonizes effects of phenylephrine on isolated rabbit prostate muscle in vitro and on intra-urethral pressure in rats.
