To understand the phenol’s contribution to potency, the phenol (17) was removed which led to a 13-fold loss in biochemical potency (38 nM). Interestingly this change, rather than attempting to mimic the phenol’s hydrogen bonding, was ... WebIsosteres were initially defined as those compounds or groups of atoms that have the same number and arrangement of electrons. A further extension to this concept of isosteres came about in 1925 with Grimm's Hydride Displacement Law. "Atoms anywhere up to four places in the periodic system before an inert gas change
