MCUF-651 (MCUF651) is a small molecule guanylyl cyclase A receptor (GC-A) positive allosteric modulator (PAM), potentiate ANP-mediated cGMP with EC50 of 0.45 uM (Emax=82%) in HEK293 GC-A cells.MCUF-651 enhanced ANP-mediated cGMP generation in human cardiac, renal, and fat cells and inhibited cardiomyocyte hypertrophy in vitro.MCUF-651 binds to GC-A (Kd=397 nM) and selectively enhances the binding of ANP to GC-A ( MCUF-651+ANP, Kd=0.06 nM).MCUF-651 is orally bioavailable in mice and enhances the ability of endogenous ANP and BNP to generate GC-A-mediated cGMP ex vivo.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
