Two virtual screening strategies, "query by bagging" (QBag) and "query by bagging with descriptor-sampling" (QBagDS), based on active learning were devised. The QBag strategy generates multiple structure-activity relationship rules by bagging and selects compounds to improve the rules. To find many structurally diverse hits, the QBagDS strategy generates rules by bagging with descriptor sampling.

To improve water solubility and to study structure-activity relationships, we modified the structure of the pyrimidine nucleus of each of a series of potent ET(A) antagonists, 3a and 4a, at the 2-position. In a previous study, each of these antagonists showed an extremely high affinity for the ET(A) receptor in porcine aortic membrane (IC(50) 3a; < 0.001 nM, 4a; 0.
