5-[5,6,7,8-TETRAHYDRO-3,5,5,8,8-PENTAMETHYL-2-NAPHTHALENYL-METHYL]-N-(2,4,6-TRIMETHOXYPHENYL)-2-FURANCARBOXAMIDE Usage And Synthesis

Uses

AG 045572 is a nonpeptidic GnRH antagonist and has the potential as an oral therapeutic treatement for sex hormone-dependent diseases and infertility.

Biological Activity

Selective gonadotropin-releasing hormone (GnRH) receptor antagonist (K i values are 2.2, 3.8 and 6.0 nM for mouse, rat and human receptors respectively). Suppresses testosterone and luteinising hormone (LH) levels in vivo .

in vivo

AG-045572 (10 mg/kg (i.v.) or 20 mg/kg (p.o.), one time) give to intact male rats, it showed medium T1/2, CL and Vss but oral bioavailability was low, in female rats the bioavailability was much higher (24%), in castrated male rats the pharmacokinetics was similar to that in female rats[1].
AG-045572 (40 mg/kg, i.m. twice a day for 3 days) pretreated of intact male rats resulted in a change of its pharmacokinetics, the parameters became similar to those in female and castrated male rats[1].
Pharmacokinetic Parameters of AG-045572 in Rats after Administration at 10 mg/kg i.v. and 20 mg/kg p.o.[1]

Animal Model:Male rats were surgically castrated via scrotal approach under halothane anesthesia and allowed 14 days post-operative recovery prior to study[1]
Dosage:10 mg/kg, 20 mg/kg; 40 mg/kg
Administration:administered acutely at 10 mg/kg (i.v.) or 20 mg/kg (p.o.), one time; For multiple-dose pretreatment, male rats at 40 mg/kg, i.m. twice a day for 3 days.
Result:Showed medium T1/2, CL and Vss but oral bioavailability was low, in female rats the bioavailability was much higher (24%)
Became similar to those in female and castrated male rats.
