Corin is a dual inhibitor of histone lysine specific demethylase (LSD1) and histone deacetylase (HDAC) , with a K i (inact) of 110 nM for LSD1 and an IC 50 of 147 nM for HDAC1 .
In Vitro
Corin is able to inhibit the deacetylation of semisynthetic, reconstituted nucleosomes by the CoREST ternary complex. Corin shows irreversible inhibition of HDAC1 activity. In Comparison to MS-275, corin appears to more potently (Corin EC 50 95 nM vs. MS-275 EC 50 420 nM) and efficaciously induce cellular H3K9 acetylation. Interestingly, Corin (1 μM) is non-toxic to primary human melanocytes in contrast to MS-275 (1 μM). MCE has not independently confirmed the accuracy of these methods. They are for reference only.
