Chemical tractability

Figure 4.10 Hit progression scheme for compounds identified from high-throughput screening. Note that the specific sequence of activities may vary from one organization to another, or even from one project to another, depending on practical considerations. For example, the location within the sequence of the chemical tractability filter may come before or after confirmation of reproducibility.

Run the screen identify hits and assess chemical tractability. 

Chemically tractable scaffolds, not complex (amenable to analogue synthesis). 

Chemical tractability a more subjective flag that is based on a medicinal chemist s view on whether this is a good start for a medicinal chemistry program. 

Finally, lots of proposed binders will probably be uncovered in de novo design. A way to triage them is needed. But since the method relies on docking and scoring, the same problem that confronts virtual screening applies here too not even reliable rank ordering can be expected. Chemical tractability, not predicted binding affinity, will probably determine which compounds get made first or at all. 

The anionic polymerization of methacrylate esters is a versatile method for preparing polymers with well-defined compositions and a large variety of chemically tractable functional groups. The method provides the ability to prepare oligomers and polymers over a wide range of molecular weights. Thus, it provides materials for study of functional group...
