Effect of Alpinia katsumadai Hayata on House Dust Mite-Induced Atopic Dermatitis in NC/Nga Mice
We evaluated the effects of Alpinia katsumadai Hayata (AKH, Zingiberaceae) extract on the production of nitric oxide (NO) and prostaglandin E(2) (PGE(2)) in RAW 264.7 cells, thymus- and-activation-regulated chemokine (TARC/CCL17) in HaCaT cells, and histamine level in HMC-1 cells. In an in vivo experiment, atopic dermatitis was induced by topical application of house dust mites for 4 weeks, and...
متن کاملInhibition of Cyclooxygenase Type 1 and 2 Enzyme by Aqueous Extract of Elaeagnus Angustifolia in Mice
Introduction: It has been shown that the extract of Elaeagnus angustifolia can inhibit inflammation and pain induced by formalin in mice and rats. The aim of the present study is to reach evaluations of possible cellular and molecular mechanisms of Elaeagnus angustifolia extract in reducing pain and inflammation through examining the extract ability for inhibition of cyclooxygenase (Cox) type ...
متن کاملHeat Shock Protein-Inducing Property of Diarylheptanoid Containing Chalcone Moiety from Alpinia katsumadai.
A new diarylheptanoid containing a chalcone moiety, katsumain H (1), was isolated from the seeds of Alpinia katsumadai. The structure was elucidated using a combination of 1D/2D NMR spectroscopy and mass spectrometry data analysis. The absolute configurations of C-3, C-5, and C-7 in 1 were assigned based on its optical rotation and after comparing its NMR chemical shifts with those of its diast...
متن کاملCyclooxygenase-2 (COX-2) Inhibition Constrains
Indoleamine 2,3-dioxygenase 1 (IDO1) metabolizes L-tryptophan to kynurenines (KYN), inducing T-cell suppression either directly or by altering antigen-presenting-cell function. Cyclooxygenase (COX)-2, the rate-limiting enzyme in the synthesis of prostaglandins, is over-expressed by several tumours. We aimed at determining whether COX-2 inhibitors down-regulate the IFN--induced expression of ID...
متن کاملAcyclic Triterpenoids from Alpinia katsumadai Inhibit IL-6-Induced STAT3 Activation.
The seeds of Alpinia katsumadai yielded two new acyclic triterpenoids, 2,3,6,22,23-pentahydroxy-2,6,11,15,19,23-hexamethyl-tetracosa-7,10,14,18-tetraene (3) and 2,3,6,22,23-pentahydroxy-2,10,15,19,23-hexamethyl-7-methylenetetracosa-10,14,18-triene (4), as well as two known compounds, 2,3,22,23-tertrahydroxy-2,6,10,15,19,23-hexamethyl-tetracosa-6,10,14,18-tetraene (1) and 2,3,5,22,23-pentahydrox...
