α1-Adrenoceptor Agonists: The Identification of Novel α1A Subtype Selective 2′-Heteroaryl-2-(phenoxymethyl)imidazolines
摘要:
Novel 2'-heteroaryl-2-(phenoxymethyl)imidazolines have been identified as potent agonists of the cloned human alpha(1)-adrenoceptors in vitro. The nature of the 2'-heteroaryl group can have significant effects on the potency, efficacy, and subtype selectivity in this series. alpha(1A) Subtype selective agonists have been identified.

Provided is a cyclometalated transition metal complex represented by Formula 1, Formula 2 or Formula 3:
By including a new ancillary ligand, the cyclometalated transition metal complex can efficiently emit red light using a phosphor by intersystem crossing (ISC) of excitons to triplet states and then metal to ligand charge transfer (MLCT). An organic light emitting device prepared using the transition metal compound shows high luminous efficiency and high external quantum efficiency.
