Terazosin structure?

Terazosin Chemical Structure

Terazosin, a non-selective α1-adrenergic receptor antagonist used in the treatment of hypertension and benign prostatic hyperplasia, has a chemical structure consisting of a phenothiazine ring system.

Phenothiazine Ring System

[1] The phenothiazine ring system in terazosin is a planar, six-membered ring featuring a sulfur atom (S) and two nitrogen atoms (N). This ring system is responsible for the compound's α1-adrenergic blocking activity.

R-Group Substituents

[1] The terazosin molecule has a number of R-group substituents attached to the phenothiazine ring system, including a piperazine ring, a methyl (CH3) group, and an ethyl (C2H5) group.
