标题 :Enzymatic synthesis of statins and intermediates thereof
权利人:LEK PHARMACEUTICALS
摘要:The present invention discloses a process for preparing an active pharmaceutical ingredient (API) or intermediates thereof, notably particular step in the synthesis of an intermdiate useful for example in the preparation of statins, by using an enzyme capable of catalyzing oxidation or dehydrogenation. The invention further provides an expression system effectively translating said enzyme. In addition, the invention relates to a specific use of such enzyme for preparing API or intermediate thereof, and in particular for preparing statin or interemediate thereof.

摘要:Nonanoyl vanillylamide succinate was synthesized from synthetic capsaicin (nonanoyl vanillylamide) and succinic anhydride. The antinociceptive and cardiovascular effects of nonanoyl vanillylamide and its derivatives were investigated. We found that nonanoyl vanillylamide and nonanoyl vanillylamide succinate strongly inhibited the writhing response, led to the vascular smooth muscle relaxation, produces bradycardia and a fall of blood pressure. The potency of nonanoyl vanillylamide succinate was found to be slight greater than that of nonanoyl vanillylamide, when compared with the same molar dose/kg of their administrations.
