identification of a small-molecule inhibitor (1) of the Trypanosoma cruzi cruzain enzyme, a validated drug target for Chagas disease. Subsequent comprehensive structure-based drug design and structure-activity relationship studies led to the discovery of carbamoyl imidazoles as potent, reversible, and competitive cruzain inhibitors. The most potent carbamoyl imidazole inhibitor (45) exhibited high affinity

The synthesis is described of a series of derivatives of 1-phenoxy-3-phenoxyalkylamino-2-propanols and 1-alkoxyalkylamino-3-phenoxy-2-propranols. The compounds were investigated for their beta-adrenoceptor blocking properties and many showed a surprising degree of cardioselectivity when tested in vivo in anesthetized cats for their effects on an isoproterenol-induced tachycardia and depressor response. The structure-activity relationship shown by this series of compounds is related to that of known cardioselective analogues and a possible reason for their cardioselectivity is discussed.

reductase (ENR) is a key enzyme of plasmodial typeIIfattyacidbiosynthesis (FASII). It has been shown to be essential for liver‐stage development of Plasmodium berghei and is therefore qualified as a target for true causal chemoprophylaxis. Using virtual screening based on two crystal structures of PfENR, we identified a structurally novel class of FASinhibitors. Subsequent chemical optimization yielded
