22731815-0	2012	Virtual screening identifies novel sulfonamide inhibitors of ecto-5"-nucleotidase.	Sulfonamides	35-46	5'-nucleotidase ecto	Homo sapiens	61-81	
24012379-3	2013	For example, a virtual screening study using a molecular model of the enzyme has led to the identification of a new series of sulfonamide-containing e5NT inhibitors.	Sulfonamides	126-137	5'-nucleotidase ecto	Homo sapiens	149-153	
24012379-8	2013	Taken together, the results rationalize the computer-aided discovery of sulfonamide inhibitors of e5NT and provide further support for the use of carefully built protein models for virtual screening.	Sulfonamides	72-83	5'-nucleotidase ecto	Homo sapiens	98-102
