dicentrine hydrochloride

Dicentrine HCl is the salt form of Dicentrine, an alpha 1-adrenoceptor antagonist effective against human hyperplastic prostates.

Dicentrine is an alkaloid-enriched fraction and the primary alkaloid of the leaves of Ocotea puberula (Lauraceae), a native Brazilian plant traditionally used by Indigenous populations for skin affections, and dicentrine further demonstrates pharmacological activity as an α1-adrenoceptor antagonist in human hyperplastic prostate tissue. Dicentrine has been evaluated using radioligand binding assays with [3H]prazosin and in vitro isometric tension experiments, confirming functional α1-adrenoceptor involvement and supporting therapeutic relevance in disorders associated with prostate hyperplasia.

Dicentrine, (-)- (NSC-251699) is an aporphinic alkaloid found in several plant species, which showed significant antinociceptive activity in an acute model of visceral pain in mice.
