However, the higher affinity for the NADH co-factor over NAD(+) and its availability in the natural environment makes the NADH complex form of ENR an attractive target. Herein, we have examined a benzimidazole family of inhibitors which target the NADH form of Francisella ENR, but despite good efficacy against Toxoplasma gondii, the IC50 for T. gondii ENR is poor, with no inhibitory activity at 1muM. Moreover similar benzimidazole scaffolds are potent against fungi which lack the ENR enzyme and as such we believe that there may be significant off target effects for this family of inhibitors. The benzimidazole based drugs show good activity against T. gondii but poor activity against its proposed enoyl reductase enzyme target.,Wilkinson C, McPhillie MJ, Zhou Y, Woods S, Afanador GA, Rawson S, Khaliq F, Prigge ST, Roberts CW, Rice DW, McLeod R, Fishwick CW, Muench SP Bioorg Med Chem Lett. 2014 Feb 1;24(3):911-6. doi: 10.1016/j.bmcl.2013.12.066., Epub 2013 Dec 22.
