21053896-0	2010	Hydroxycoumarin derivatives: novel and potent alpha-glucosidase inhibitors.	3-hydroxycoumarin	0-15	sucrase-isomaltase	Homo sapiens	46-63	
21053896-1	2010	A novel class of hydroxycoumarin derivatives were found to be potent alpha-glucosidase inhibitors.	3-hydroxycoumarin	17-32	sucrase-isomaltase	Homo sapiens	69-86	
21053896-4	2010	Among all hydroxycoumarin derivatives studied, compounds 10 and 11 exhibited the highest activities, were specific inhibitors of alpha-glucosidase, and could be exploited as the lead compounds for the development of potent alpha-glucosidase inhibitors.	3-hydroxycoumarin	10-25	sucrase-isomaltase	Homo sapiens	129-146
