A robust classification-dependent multi-molecular modelling study on some biphenyl sulphonamide based MMP-8...

Area of Science:

• Biochemistry and Molecular Biology
• Medicinal Chemistry
• Structural Biology

Background:

• Matrix metalloproteinases (MMPs) are crucial enzymes involved in extracellular matrix remodeling.
• Matrix metalloproteinase-8 (MMP-8) is implicated in various diseases, including periodontal disease, cancer, and cardiovascular disorders.
• Targeted inhibition of MMP-8 is a therapeutic strategy for managing these conditions.

Purpose of the Study:

• To explore structural features influencing the activity of biphenyl sulphonamide (BPS)-based MMP-8 inhibitors.
• To identify key molecular determinants for potent MMP-8 inhibition.
• To guide the design of novel, highly effective MMP-8 inhibitors.

Main Methods:

• Classification-based molecular modeling techniques were employed.
• Structure-activity relationships of a series of BPS-derived MMP-8 inhibitors were analyzed.
• The influence of specific functional groups on inhibitory activity was evaluated.

Main Results:

• The study identified specific structural features, including tetrahydroisoquinoline and N-Boc pyridyl groups, that positively impact MMP-8 inhibition.
• The importance of zinc-binding groups (ZBGs) such as hydroxamate and phosphonate for achieving potent, sub-nanomolar inhibition was confirmed.
• Structural insights were gained into the molecular interactions driving MMP-8 inhibition.

Conclusions:

• Biphenyl sulphonamide (BPS) derivatives with specific structural motifs show promise as MMP-8 inhibitors.
• Tetrahydroisoquinoline and N-Boc pyridyl groups are critical for enhancing MMP-8 inhibitory potency.
• Optimizing zinc-binding groups is essential for developing sub-nanomolar MMP-8 inhibitors for therapeutic applications.
