Virstatin is a small molecule that inhibits the activity of the cholera protein, ToxT. [1]

Its activity in cholera was first published in 2005 in a paper that described the screening of a chemical library in a phenotypic screen and subsequent testing of one of the hits in infected mice. [1] [2]

The compound is an isoquinoline alkaloid [3] and can be synthesized by a simple two-step synthesis [4]
