Area of Science:

  • Computational biology
  • Pharmacology
  • Dermatology

Background:

  • Psoriasis (PSO) is a chronic inflammatory skin disease with significant physical and mental health impacts.
  • Current treatments for psoriasis face challenges with drug resistance and lack of specific therapies.

Purpose of the Study:

  • To screen for novel drug candidates for psoriasis using molecular dynamics (MD) simulations.
  • To identify potential therapeutic targets and compounds for psoriasis treatment.

Main Methods:

  • Differential gene expression analysis of psoriasis data from the Gene Expression Omnibus (GEO) database.
  • Prediction of target proteins and small molecules using the Connectivity Map (cMAP) database.
  • Molecular docking and MD simulations to assess protein-compound binding stability and interactions.

Main Results:

  • 1999 differentially expressed genes were identified in psoriasis.
  • Lymphocyte cell-specific protein-tyrosine kinase (LCK) was identified as a highly expressed target in psoriasis, with aminogenistein predicted as a targeting compound.
  • MD simulations confirmed stable binding of aminogenistein to LCK, with favorable binding energy and interactions.

Conclusions:

  • Aminogenistein exhibits strong protein-ligand interactions and stability with LCK.
  • Aminogenistein represents a novel and promising drug candidate for psoriasis treatment.
