5α-Dihydrocorticosterone

5α-Dihydrocorticosterone (5α-DHC, 5α-DHB), also known as 11β,21-dihydroxy-5α-pregnane-3,20-dione, is a naturally occurring, endogenous glucocorticoid steroid hormone and neurosteroid.[1][2][3] It is biosynthesized from corticosterone by the enzyme 5α-reductase.[4][5][6] DHC has central depressant effects and impairs long-term potentiation in animals.[7][8]
