Description:

WARNING: This product is for research use only, not for human or veterinary use.

BMY 7378 is an agonist at 5-HT1A receptors mediating hypotension and renal sympatho-inhibition in anaesthetised cats. BMY 7378 is also an alpha (2C)-adrenoceptor antagonist. BMY 7378 is a hypotensive agent in the rat, but that its actions are mediated, in part, by central 5-HT(1A) receptor stimulation in the adult and by a nonserotonergic mechanism in the young rat.

Biological target:

An α2C- and α1D-adrenoceptor antagonist and 5-HT1A partial agonist.

In vitro activity:

In ligand-binding studies, BMY 7378 showed 10-fold selectivity for alpha(2C)-adrenoceptors (pK(i) of 6.54) over other alpha(2)-adrenoceptors. It is concluded that BMY 7378, in addition to alpha(1D)-adrenoceptor selectivity in terms of alpha(1)-adrenoceptors, shows selectivity for alpha(2C)-adrenoceptors in terms of alpha(2)-adrenoceptors. Reference: Auton Autacoid Pharmacol. 2005 Oct;25(4):135-41. https://pubmed.ncbi.nlm.nih.gov/16176444/

In vivo activity:

By 30 weeks of age, SHR (spontaneously hypertensive rats) exhibited significant hypertension and cardiac hypertrophy. BMY 7378 and captopril decreased blood pressure and improved hemodynamic parameters and cardiac function in treated SHR vs. untreated SHR (P < 0.05). Histology showed increased cardiomyocyte size, fibrosis, and left ventricular hypertrophy in SHR hearts. BMY 7378 ameliorated fibrosis and cardiac hypertrophy, but had no effect on cardiomyocyte size in SHR. Effects of BMY 7378 were associated with increased α1D-AR protein expression in SHR.
