HTHQ, which is a hydroquinone monoalkyl ether, is a potent anti-oxidative agent, even at low dose levels.HTHQ is found to be a potent anti-lipid-peroxidative compound and its antioxidation activity to be extremely elevated in biological systems, such as that of liver microsomes via the generation of stable free radicals. In vitro: HTHQ exhibits a similar anti-oxidative activity to that of D,L-alpha-tocopherol against lipid peroxidation in linolate micelles initiated by addition of Fe2+. HTHQ exhibits approximately 4.8-fold higher anti-lipid-peroxidation activity than that of D,L-alpha-tocopherol against the peroxidation in phosphatidylcholine liposomes initiated by addition of Fe2+. [1] up to 0.125% HTHQ significantly reduced the effects of 0.02% Glu-P-1 or 0.03% MeIQx on the number and area of foci. [2]In vivo: Treatment with HTHQ potently inhibits PhIP-induced mammary carcinogenesis in female rats without prior initiation treatment. . HTHQ administration shows reduced mRNA level of PDGF (Plateletderived growth factor) , α-SMA (α-smooth muscle actin) and TGF-β (transforming growth factor-β) than DMN-induced hepetic fibrosis animals in the liver tissue. In this study, we showed that HTHQ improves against DMN-induced liver fibrosis in male SD rats.[3]
