BRL-50481 is a selective inhibitor of phosphodiesterase 7 (PDE 7) that has acceptable selectivity for in vitro studies. Studies suggest that BRL-50481 is used to inhibit the activity of hrPDE7A1 which is usually expressed in baculovirus-infected Spodoptera frugiperda in a competitive manner. In osteoblasts, BRL-50481increases mineralization and bALP as a result of PDE7 silencing which upregulates several osteogenic genes. Further studies show that BRL-50481increases apoptosis in CLL cells via a mitochondrial-dependent process, and is associated with increased cAMP accumulation and down-regulation of the antiapoptotic protein survivin. BRL-50481 is a inhibitor of PDE7A.

Sample Use Guides

In Vivo Use Guide

Rats: accumbal injection of 4ug/0.3uL of BRL-50481 decreased rats' anxiety. The i.p. injection of 0.2mg/kg of BRL-50481 was able to increase the PVN TRH mRNA expression and to decrease feeding but did not change animals' anxiety levels; in contrast, 2mg/kg b.w BRL-50481 enhanced accumbal TRH mRNA, induced anxiolysis with no change in food intake.

Route of Administration: Intraperitoneal

In Vitro Use Guide

At substrate concentrations of 50 nM and 1 uM, BRL-50481 inhibited the hydrolysis of cAMP by hrPDE7A1 with IC50 values of 0.26 and 2.4 uM, respectively. BRL-50481 failed to significantly inhibit PDE1B, PDE1C, PDE2, and PDE5 at concentrations below 100 uM. BRL-50481 suppressed, in a concentration-dependent manner, LPS-induced TNF release in human monocytes in which PDE7A1 was induced (21.7 1.6% inhibition at 30 uM at the 12-h time point).
