Area of Science:

Medicinal Chemistry
Computational Drug Discovery
Biochemistry

Background:

Protein kinases are critical regulators of cellular processes.
Dysregulation of kinases is implicated in diseases such as cancer and autoimmune disorders.
Kinases are vital drug targets, making kinase inhibitor development a key area of research.

Purpose of the Study:

To address the computational challenges in fragment-based drug discovery (FBDD) for kinase inhibitors.
To introduce CustomKinFragLib, a pipeline for curating and reducing fragment libraries.
To generate a smaller, more tractable, and synthesis-friendly fragment set for kinase inhibitor design.

Main Methods:

Developed CustomKinFragLib, a user-oriented pipeline building on the KinFragLib framework.
Implemented a systematic post hoc reduction and filtering strategy for fragment sets.
Integrated literature-derived drug-relevant filters, including synthetic accessibility and drug-likeness properties.

Main Results:

Reduced the KinFragLib library from 9131 to 837 fragments.
Retained diverse fragments with drug-like properties and high synthetic tractability.
Generated a practical fragment set suitable for downstream kinase inhibitor design workflows.

Conclusions:

CustomKinFragLib offers a practical and customizable solution for generating focused fragment libraries for kinase inhibitor discovery.
The pipeline enhances the efficiency of FBDD by providing curated, synthesis-friendly fragment sets.
This approach facilitates the design of novel kinase inhibitors for therapeutic applications.
