Potent inhibition of Norwalk virus by cyclic sulfamide derivatives.

ABSTRACT

A new class of compounds that exhibit anti-norovirus activity in a cell-based system and embody in their structure a cyclosulfamide scaffold has been identified. The structure of the initial hit (compound 2a, ED(50) 4 µM, TD(50) 50 µM) has been prospected by exploiting multiple points of diversity and generating appropriate structure-activity relationships.
