5-hydroxymethyl tolterodine

5-Hydroxymethyl tolterodine (formate) (PNU-200577 (formic)) is an active metabolite of the muscarinic acetylcholine receptor antagonists Tolterodine and Fesoterodine. It is synthesized by the cytochrome P450 (CYP) isoenzyme CYP2D6 and plasma esterases.

(Rac)-5-Hydroxymethyl Tolterodine hydrochloride, also known as (Rac)-Desfesoterodine hydrochloride, is an active metabolite of Tolterodine that functions as a mAChR antagonist. It exhibits significant affinity (K i values) for M1, M2, M3, M4, and M5 receptors, with values of 2.3 nM, 2 nM, 2.5 nM, 2.8 nM, and 2.9 nM, respectively. This compound is commonly employed in research related to overactive bladder conditions.

(Rac)-5-Hydroxymethyl Tolterodine is a useful organic compound for research related to life sciences. The catalog number is T66168 and the CAS number is 200801-70-3.

Desfesoterodine (5-HMT) is a new muscarinic receptor antagonist with Kb of 0.84 nM.

Fesoterodine fumarate (Toviaz) is the fumarate salt form of fesoterodine, a competitive muscarinic receptor antagonist with muscle relaxant and urinary antispasmodic properties. Fesoterodine is rapidly hydrolyzed in vivo into its active metabolite 5-hydroxymethyl tolterodine, which binds and inhibits muscarinic receptors on the bladder detrusor muscle, thereby preventing bladder contractions or spasms caused by acetylcholine.
