SERP Comments:

This probe might be suitable for in vivo studies via non-standard dosing technologies (minipump or IP injection, twice daily with CYP inhibitor co-dosing) but not enough ADME data are provided to know which technology could work.

SERP Comments:

A thorough exploration of the cellular effects of the compound is presented, but the DMPK data are not sufficiently good to allow in vivo evaluation via standard oral or IV dosing.

SERP Comments:

The probe is a potent and selective ERK5 inhibitor. The data look convincing, and selectivity against other kinases is particularly strong (limited other selectivity data disclosed aside from key bromodomain targets). Importantly, data are presented for target engagement within the cell and cellular and isolated biochemical potencies are similar. Recommended for use in vitro and/or in cells. No data were ncluded to support use of this probe in model organisms.
