Abstract

MK2, MAP-activated protein kinase 2, plays an important role in the regulation of innate immune response as well as in cell survival upon DNA damage. Despite its potential in the treatment of inflammation and cancer, up to date no MK2 low molecular weight inhibitor reached the clinic, mainly because of inadequate ADME properties of the developed inhibitors. In this paper we describe an approach based on specifically placed fluorine within a recently described pyrrole-based MK2 inhibitor scaffold for manipulation of its physicochemical and ADME properties. While keeping the target potency, the novel fluoro-derivatives showed not only improved permeability but also enhanced solubility and reduced in vivo clearance leading to significantly increased oral exposure.
