PX-13-17OH is an irreversible, isoform non-specific Wortmannin analog which potently inhibits PI3Ka/b/g/d (IC50 = 6.4 nM, 13 nM, 8 nM and 11 nM respectively). PX-13-17OH does not appreciably inhibit mTOR (IC50 = 2.92 mM). In a kinase panel PX-13-17OH did not show significan inhibition of other kinases (IC50 > 10 mM). In a cellular assay PX-13-17OH inhibited the LNCap cell line (IC50 = 0.39 mM). In a nude mouse xenograft model (U87MG glioma) PX-13-17OH showed potent inhibition of tumor growth aldeardy at 1.25 mg/Kg in iv dosing. See also our product PX-866-17OH (Cat# CD0323) and 17-b-Hydroxywortmannin (Cat# CD0278) with similar activity.
