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.
