Using Bioactivity Profiling to Support the Progression of Phenotypic Hits


Bioactivity profiling has been traditionally used to assess the selectivity of new drug candidates in the context of target based approaches, where pharmacological selectivity is a key requirement. Phenotypic screening provides hit molecules where the only initial constrain is activity in a functional assay, without placing any limitation on the starting selectivity. Subsequent progression of these hits requires bioactivity profiling tools to pin-point relevant and not relevant activities in order to support candidate optimisation.

What you will learn…

In this webinar, you will learn how to address the optimisation of hits derived from a target-agnostic phenotypic screen, using a strategy based on combining bioactivity profiling and reference compound characterisation. During this webinar, speaker Arsenio Nueda gave an example of a recent case study.

About this case study

In this case study a phenotypic screen was performed using poly I:C / IL-4 stimulated human bronchial epithelial cells interrogated with a 44,974 compound library. This resulted in the identification of 7 representative hits which down regulated TSLP protein and mRNA levels and provided chemistry and biology starting points for new drug discovery opportunities.
