ML395, formerly known as VU0468809, is a novel and potent PLD2 inhibitor. ML39 showed potent antiviral activity. ML395 (VU0468809), a potent, >80-fold PLD2 selective allosteric inhibitor (cellular PLD1, IC50 >30,000 nM; cellular PLD2, IC50 =360 nM). Moreover, ML395 possesses an attractive in vitro DMPK profile, improved physiochemical properties, ancillary pharmacology (Eurofins Panel) cleaner than any other reported PLD inhibitor, and has been found to possess interesting activity as an antiviral agent in cellular assays against a range of influenza strains (H1, H3, H5 and H7).
