Antiplatelet Activity of α-Lipoic Acid was written by Lai, Yuan-Shu;Shih, Ching-Yu;Huang, Yu-Feng;Chou, Tz-Chong. And the article was included in Journal of Agricultural and Food Chemistry in 2010.Category: tetrahydrofurans This article mentions the following:
α-Lipoic acid (ALA) is often used as a dietary supplement to prevent and treat chronic diseases associated with excessive oxidative stress. The aim of this study was to investigate the mechanisms of the antiplatelet activity of ALA. ALA significantly inhibited collagen-induced platelet aggregation, thromboxane B2 (TXB2) formation, Ca2+ mobilization, and protein kinase Cα (PKCα) activation, but ALA itself increased cAMP formation in rabbit washed platelets. However, the effects of ALA on the above platelet responses were markedly reversed by the addition of 2’5′-ddAdo, an adenylate cyclase inhibitor. Addnl., increased reactive oxygen species (ROS) formation and cyclooxygenase-1 activity stimulated by arachidonic acid were inhibited by ALA. In conclusion, we demonstrated that ALA possesses an antiplatelet activity, which may be associated with an elevation of cAMP formation, involving subsequent inhibition of TXA2, Ca2+ mobilization, and PKCα-mediated pathways. Moreover, inhibition of ROS formation and increase of platelet membrane fluidity may also involve its actions. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6Category: tetrahydrofurans).
(2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-methyltetrahydrofuran-3-ol (cas: 6698-26-6) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF) is a Lewis base that bonds to a variety of Lewis acids such as I2, phenols, triethylaluminum and bis(hexafluoroacetylacetonato)copper(II). THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Category: tetrahydrofurans
