Abstract/OtherAbstract:
Recently a novel method termed compound set enrichment (CSE) has been described which uses the activity distribution of a structural class of compounds to identify hit series from primary screening data. This report describes how this method can be used to identify such hit series, even when no hits according to conventional hit-calling methods for a given structural class are present in the dataset. Such series, which were called latent hit series, were identified prospectively in a cell based screening campaign and also in a series of retrospective analysis of publically available datasets from PubChem. The assay used for the prospective case study was developed to identify compounds modulating protein translation directed from the Internal Ribosome Entry Site (IRES) of the Encephalomyocarditis Virus (EMCV) genomic RNA. The assay was designed with the ability to detect two assay readouts. The first assay readout monitors compound effects on IRES-directed translation and the second readout monitors the cell viability and general effect on protein expression. By applying CSE separately to both of them six validated latent hit series with apparently no effects on cell viability were identified. For each of these series, further testing of new compounds enabled identification of additional hits, also apparently with no effect on cell viability. These validated latent hit series would have been missed by a conventional cut-off based hit-calling approach. This prospective study further supports CSE as a method for the analysis of high throughput screening experiments.
