FASN and infection: We first assayed the potency of IMP1088, DDD85646 and C75, a fatty acid synthase inhibitor (tenfold serial dilutions for concentrations ranging from 1 nM to 10 μM) in A549 cells infected with MOPV, LASV, MACV or YFV 17D (MOI 0.01) for inhibiting the production of infectious particles in a multi-cycle infection experiment.
