Delphinidin 3-(6"-acetylgalactoside) is a member of the class of compounds known as anthocyanidin-3-o-glycosides. Anthocyanidin-3-o-glycosides are phenolic compounds containing one anthocyanidin moiety which is O-glycosidically linked to a carbohydrate moiety at the C3-position. Delphinidin 3-(6"-acetylgalactoside) is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Delphinidin 3-(6"-acetylgalactoside) can be found in highbush blueberry and lowbush blueberry, which makes delphinidin 3-(6"-acetylgalactoside) a potential biomarker for the consumption of these food products.

C18H23N5NaO9P (507.11310380000003)


Dibutyryl-cGMP sodium (Bt2cGMP sodium) is a cell-permeable cGMP analogue. Dibutyryl-cGMP sodium preferentially activates cGMP-dependent protein kinase (PKG). Dibutyryl-cGMP sodium inhibits the release of [3H]-arachidonic acid from γ thrombin-stimulated human platelets. Dibutyryl-cGMP sodium induces peripheral antinociception via activation of ATP-sensitive K+ channels[1][2][3].
