    Rolipram
    		Inhibitor 99.87%
    Rolipram is a PDE4 inhibitor, with blood-brain barrier permeability, that reverses β-amyloid-induced learning and memory impairment in rats.

Rolipram promotes neuronal differentiation of human bone marrow mesenchymal stem cells and inhibits Methamphetamine- and morphine-induced hyperlocomotion in mice. Rolipram also reduces the viability of glioblastoma stem-like cells and enhances Bevacizumab (HY-P9906)-induced cell death. Rolipram inhibits the expression of proinflammatory cytokines and enhances central noradrenergic transmission. Rolipram is mainly used in studies related to various central nervous system diseases including Alzheimer's disease, major depressive disorder, glioblastoma multiforme, and multiple sclerosis.
