Alpha-naphthoflavone inhibits the metabolism of 3,4-benzopyrene and 7,12-dimethylbenz(a)anthracene in hamster enlbryo cell cultures and protects the cells against the inhibition of cell multiplication by these carcinogens. Alphla-nalphthoflavone also inhibits the aryl hydrocarbon hydroxylase activity in homogenates of induced hamster embryo cells and in liver microsomes from rats previously treated with polycyclic aromatic hydrocarbons, but not in microsomes from control rats.

The aim of this study was to systematically examine the inhibitory mechanisms of the flavonoid α-naphthoflavone (α-NF) in platelet activation. In this study, α-NF concentration dependently (5−20 μM) inhibited platelet aggregation stimulated by agonists. α-NF (5 and 10 μM) inhibited intracellular Ca
2+ mobilization, phosphoinositide breakdown, and thromboxane A2 formation stimulated by collagen (1 μg/mL) in human platelets. In addition, α-NF (5 and 10 μM) markedly increased levels of cyclic GMP and cyclic GMP-induced vasodilator-stimulated phosphoprotein (VASP) Ser157 phosphorylation. Rapid phosphorylation of a platelet protein of Mr 47 000 (P47), a marker of protein kinase C activation, was triggered by phorbol-12,13-dibutyrate (60 nM).
