The Uses of BRL 50481

A PDE7 inhibitor that has acceptable selectivity for in vivo studies

What are the applications of Application

BRL-50481 is a selective inhibitor of PDE 7

Definition

ChEBI: BRL-50481 is a C-nitro compound that is benzene substituted by N,N-dimethylaminosulfonyl, methyl and nitro groups at positions 1, 2 and 5, respectively. It is a phosphodiesterase inhibitor selective for the PDE7 subtype (Ki = 180 nM). It has a role as an EC 3.1.4.53 (3',5'-cyclic-AMP phosphodiesterase) inhibitor, a geroprotector and a bone density conservation agent. It is a sulfonamide, a C-nitro compound and a member of toluenes.

Biological Activity

Selective, substrate-competitive inhibitor of phosphodiesterase (PDE) 7 (K i = 180 nM). Displays > 200-fold selectivity over PDE1B, PDE1C, PDE2, PDE3, PDE4A4 and PDE5.

Biochem/physiol Actions

BRL 50481 is a potent and selective PDE7 inhibitor (IC50 = 260 nM).
