What Do Molecules That Look LIke This Tend To Do?

In this post, we'll take a look at how we can use an Open Source Python library to search the ChEMBL database and investigate the biology associated with compounds similar to a screening hit. Introduction A question that invariably comes up when examing screening hits is "what do molecules that look like this tend to do?".

So that is a wide range of techniques to look at the protein-ligand interactions, all with the aim to guide the optimisation of our first screening hits to potent inhibitors that hopefully are cell-active at some point.

It’s not generally possible to design a drug from screening output alone and to attempt to do so would be the equivalent of taking a shot at goal from the centre spot. Just as the midfielders try move the ball closer to the opposition goal, the hit-to-lead team use the screening hits as starting points for design of higher affinity compounds.

First, structural alerts derived from analysis of screening hits (defined as responses that exceed a threshold when assayed at a particular concentration) are not necessarily useful for assessing higher affinity compounds for which concentration responses have been determined.

A) Progression of a Novartis HAT program from a screening hit to brain-penetrant leads. This program started from an HTS screen of 3M compounds, resulting in a singleton hit (Figure 17). Figure 18. B) Results from a computational model of brain-penetration correlated well with actual K p ’s across the series.

It is quite a bit more potent than the values one finds with screening hits, which typically have IC50s in the single to double-digit µM range. Molecules with IC50 values less than 200nM are considered active, and molecules with IC50 values greater than or equal to 200nM are considered inactive.

CO-ADD is an open-access, not-for-profit initiative whereby compounds provided by researchers and industry scientists are screened against a clinically relevant panel of bacteria and fungi. Since CO-ADD may re-screen hits against resistant bacterial strains or in cytotoxicity assays, more comprehensive data is available for some compounds.

The distinction between Type 1 and and Type 2 behaviors is an important and useful one to make from the perspective of drug discovery scientists who are making decisions as to which screening hits to take forward.

We translated this concept to the discovery and development of disulfide tethering screen hits into irreversible covalent modifiers of C185. Small molecule covalent modification of C185 would block any form of prenylation and subsequently inhibit attachment of KRAS4b to the cell membrane, blocking its biological activity.
