Comments:

The cited reference (10.1016/j.chembiol.2019.03.006) is an excellent comparative study of the 5 cmpds that have been used as NMT probes and shows clearly and conclusively that only IMP-1088 and IMP-366 ( DDD85646 ) are suitable to use as orthogonal probes in vitro and in cells for the human NMT1 and NMT2 targets. Of these two, IMP-1088 is clearly the more potent probe cmpd.

Comments:

Proteomic data suggest that this compound has high specificity for NMT1 and NMT2, but genetic evidence for target specificity is still awaited. There is no information on its usefulness in animal models.

Comments:

There is no selectivity data indicating that this compound inhibits the intended target(s) without inhibiting other acyltransferases. Looking at the chemical structure, I would anticipate activity on other target classes outside of the acyltransferases. In addition, there is no negative control compound that would raise the comfort level of using this compound as a chemical probe.
