OB 24 hydrochloride is a potent and selective heme oxygenase 1 (HO-1) inhibitor (IC50 values are 1.9 and >100 μM for HO-1 and HO-2 respectively), reduces protein carbonylation and reactive oxygen species formation in advanced prostate cancer cells (PCA). Inhibits cell proliferationin vitroand PCA tumor growth and lymph node/lung metastasesin vivo. Synergizes with Taxol.
pNPS-DHA is an arylamide derivative of docosahexaenoyl ethanolamide that has anti-allergic activity.1It inhibits degranulation of RBL-2H3 mast cells (IC50= 15 μM).pNPS-DHA (1,000 mg/kg) inhibits IgE-dependent passive cutaneous anaphylaxis (PCA) in mice.
