Topological virtual screening: a way to find new compounds active in ulcerative colitis by inhibiting NF-κB

Area of Science:

• Pharmacology
• Computational Chemistry
• Immunology

Background:

• Ulcerative colitis and Crohn's disease are chronic gastrointestinal inflammatory conditions.
• Nuclear Factor Kappa B (NF-κB) is a key regulator of inflammatory and immune gene expression.

Purpose of the Study:

• To develop a predictive model for identifying novel compounds that inhibit NF-κB activity.
• To discover new therapeutic agents for ulcerative colitis by targeting NF-κB.

Main Methods:

• Topological Virtual Screening was employed using topological indices as structural descriptors.
• Linear discriminant analysis was used to build a model relating structural features to biological activity.
• A two-function discriminant model was constructed to differentiate NF-κB active/inactive and ulcerative colitis active/inactive compounds.

Main Results:

• A topological model was successfully developed with two discriminant functions.
• The model effectively discriminated between compounds based on NF-κB and ulcerative colitis activity.
• Twenty-eight novel compounds were predicted to be active and selected for experimental validation.

Conclusions:

• Topological Virtual Screening provides an effective computational approach for discovering new ulcerative colitis therapeutics.
• The developed model shows potential for identifying drug candidates that inhibit NF-κB.
• Further in vitro and in vivo studies are warranted for the 28 selected compounds.
