Replaces Prod. #: ALX-350-113

Mixture of ~65% (+)- and ~35% (-)-enantiomers. Male antifertility agent with antispermatogenic activity. Shows antitumor, antiviral and antioxidant actions. Small molecule inhibitor of Bcl-2/Bcl-XL. Induces apoptosis. Synergizes with radiation and chemotherapy in vitro. Reversible inhibitor of protein phosphatase 2B (PP2B; calcineurin). Protein kinase C (PKC) inhibitor. Inhibits activities of the mitotic kinesin Eg5 (IC50=10.8µM/L). Inhibits RBL-1, 5-lipoxygenase (IC50=0.3µM) and 12-lipoxygenase (IC50=0.7µM). Inhibits PAF and leukotriene-induced guinea pig parenchyma contractions. Novel direct-acting inhibitor of calcineurin.
