Abstract

Target-focused libraries can be rapidly selected by 2D virtual screening methods from multimillion compounds' databases if structures of active compounds are available. In the present study, a multi-step virtual and in vitro screening cascade is used to select melanin-concentrating hormone receptor-1 antagonists. The 2D similarity search combined with physico-chemical parameter filtering is suitable for selecting candidates from multimillion compounds' repository. The seeds of the first round of virtual screening were collected from literature commercial databases, whereas the seeds of the second round were the hits the first round of biological testing In vitro screening underlined the efficiency of our approach, as in the second screening round the hit rate (8.6 %) significantly improved compared to the first round (1.9 %), applying a strict requirement for hit selection, and also this cascade-like screening method was appropriate for selecting several compounds reaching efficacies even below 10 nM. © 2013 Springer Science+Business Media New York.
