title: Rapid optimization of an ICE inhibitor synthesis using multiple reaction conditions in a parallel array.
abstract: Optimization of a 2-step reaction sequence was accomplished in 3-4 days, with over 200 different reaction conditions evaluated. Combinatorial arrays were performed using the optimized conditions to synthesize 590 new compounds which were tested for inhibition against N-His (D381E) ICE. Thirty-five compounds showed at least a tenfold improvement in activity compared to an initial standard.
