Comparison of algorithms for dissimilarity-based compound selection.

Dissimilarity-based compound selection has been suggested as an effective method for selecting structurally diverse subsets of chemical databases. This article reports a comparison of several maximum-dissimilarity and sphere-exclusion algorithms for dissimilarity-based selection. The effectiveness of the algorithms is quantified by the numbers of biological activity classes identified in subsets selected from the World Drugs Index database, and by the numbers of active compounds identified in feedback searches of this database. The experiments demonstrate the general effectiveness and efficiency of the MaxMin algorithm.

Parallel-compound synthesis: methodology for accelerating drug discovery.

Parallel compound synthesis enables large numbers of individual compounds to be prepared simultaneously using semiautomated techniques. This fast and efficient methodology has an important role to play in accelerating lead optimisation and hence the whole drug discovery process. The potential of this strategy to rapidly optimise chemical leads and provide structure-activity relationship (SAR) information was demonstrated in two therapeutic areas, antiviral agents (herpes simplex virus), and neurokinin-2 receptor antagonists.

UK-69,578, a novel inhibitor of EC 3.4.24.11 which increases endogenous ANF levels and is natriuretic and diuretic.

A search for potent inhibitors of EC 3.4.24.11, an enzyme which is found most abundantly in the kidney and which degrades atrial natriuretic factor, has led to the identification of UK-69,578. Structure-activity studies starting from substituted N-carboxymethyl dipeptide inhibitors resulted in the introduction of a cyclo-alkane P1' residue and in the replacement of the aza-link between P1 and P1' residues by a methylene group, with a net ten-fold potency gain. UK-69,578 increases endogenous ANF levels and produces natriuretic and diuretic responses intravenously in mice.
