Area of Science:

  • Biochemistry
  • Molecular Biology
  • Drug Discovery

Background:

  • Apoptosis, or programmed cell death, is a critical biological process for development and maintaining organismal homeostasis.
  • Dysregulation of apoptosis is implicated in various diseases, making apoptosis regulators attractive therapeutic targets.

Purpose of the Study:

  • To identify novel inhibitors of Bcl-2 and Bcl-X(L) proteins using a computational drug discovery approach.
  • To explore the potential of identified compounds as therapeutic agents.

Main Methods:

  • Utilized computer-assisted screening of a large in-house database (>4 million molecules).
  • Employed BH3I-1 and BH3I-2 Bcl-2 inhibitors as lead compounds for virtual screening.
  • Conducted further investigations on promising identified compounds.

Main Results:

  • Successfully screened a vast chemical library to identify potential Bcl-2 and Bcl-X(L) inhibitors.
  • Identified specific compounds with inhibitory potential against key apoptosis regulators.
  • The identified molecules warrant further preclinical and clinical evaluation.

Conclusions:

  • Computer-assisted screening is an effective strategy for discovering novel apoptosis inhibitors.
  • The identified compounds represent promising leads for developing new drugs targeting Bcl-2 and Bcl-X(L).
  • Further research is necessary to validate the therapeutic potential of these drug candidates.
