Inhibitory effects of honokiol on LPS and PMA-induced cellular responses of macrophages and monocytes.

28 Sep 2009 The regulatory effects of honokiol on the cellular responses of macrophages and monocytes were evaluated. Specifically, we investigated the effects of honokiol with respect to lipopolysaccharide (LPS)-induced cytotoxicity, LPS- or ... Read more...

Inhibition of 20-hydroxyeicosatetraenoic acid synthesis using specific plant lignans: in vitro and human studies.

26 Sep 2009 Sesamin, the major lignan found in sesame, has been shown to increase vitamin E levels by inhibiting its metabolism via the cytochrome P450 isozyme CYP4F2. CYP4F2 and CYP4A11 are the predominant human isoforms that synthesize ... Read more...

Combined administration of the mixture of honokiol and magnolol and ginger oil evokes antidepressant-like synergism in rats.

24 Sep 2009 Magnolia bark combined with ginger rhizome is a common drug pair in traditional Chinese prescriptions for the treatment of depression. In the present study, we examined antidepressant-like effects of the mixture of honokiol and magnolol (HMM) from ... Read more...
