Area of Science:

  • Drug Discovery and Development
  • Structural Biology
  • Medicinal Chemistry

Background:

  • Traditional drug discovery involves sequential stages like target identification, lead identification, and optimization.
  • Current methods often require pre-identification and binding confirmation for structural data, delaying lead optimization.
  • A critical bottleneck is the selection of an appropriate lead compound to avoid later-stage complications.

Purpose of the Study:

  • To introduce a novel X-ray crystallography-driven screening technique.
  • To integrate lead identification, structural assessment, and optimization into a single, efficient process.
  • To demonstrate the method's utility in discovering and optimizing novel urokinase inhibitors for cancer treatment.

Main Methods:
