Abstract
A series of structure based drug design hypotheses and sequential screening efforts drove improvements in the potency and lipophilic efficiency of tetrahydro-pyrazolopyridine based ERK2 inhibitors. Fragment growing efforts of an early fragment lead established a new lipophilic Ph-Tyr interaction. Subsequent cleavage of a lipophilic moiety introduced a polar contact between a newly liberated N-H and a vicinal Asp, resulting in substantial improvements in the lipophilic efficiency and in vitro clearance.
