Improved enzymatic procedure for the synthesis of anandamide and N-fatty acylalkanolamine analogues: A combination strategy to antitumor activity
Twenty N-fatty acylamines from linolenic and arachidonic acids, fifteen of them new compounds, were obtained through Candida antarctica B lipase-catalyzed esterification and aminolysis reactions in very good yields and with high chemoselectivity. The optimal reaction conditions were achieved by stud...
