Electroreductive cleavage of 2-methylene-9,10-anthraquinone (Maq) esters of carboxylic acids and N-substituted carbamic acids: protecting groups for carboxylic acids and primary amines
The chemical modification of the dual histamine H-2 and gastrin receptor antagonists described in our preceding paper, particularly the modification of spacers as well as the alteration of their connecting bonds at the gastrin receptor antagonist site (GA) from the amide bond to the carbamate bond, significantly improved not only their dual activity but also the GA versus CCK-A receptor selectivity.
