Data-Driven Identification of Hydrogen Sulfide Scavengers

Area of Science:

• Biochemistry
• Chemical Biology
• Pharmacology

Background:

• Hydrogen sulfide (H₂ S) is a crucial signaling molecule with significant biological roles.
• While H₂ S up-regulation is well-studied, precise down-regulation remains a challenge due to a lack of specific inhibitors.
• Developing effective H₂ S scavengers offers a promising alternative strategy.

Purpose of the Study:

• To develop potent and specific scavengers for down-regulating hydrogen sulfide (H₂ S).
• To explore H₂ S scavengers as an alternative approach to enzyme inhibitors for controlling H₂ S levels.
• To identify novel H₂ S scavenging compounds using a data-driven strategy.

Main Methods:

• Construction of a comprehensive H₂ S sensor database to identify key compound parameters.
• Data-driven analysis of the database to select potential H₂ S scavenging compounds.
• Evaluation of selected compounds, particularly those based on the sulfonyl azide template, in in vitro and in vivo models.

Main Results:

• A database of H₂ S sensors was compiled, facilitating the selection of potential scavenging agents.
• Data analysis identified 30 promising compounds, with a subset based on the sulfonyl azide structure showing significant potential.
• The efficacy of the developed H₂ S scavengers was confirmed through rigorous in vitro and in vivo experimental validation.

Conclusions:

• Novel H₂ S scavengers, particularly sulfonyl azide derivatives, have been successfully developed.
• These scavengers provide a viable alternative for precise H₂ S down-regulation in biological systems.
• The findings pave the way for new therapeutic strategies targeting H₂ S-mediated biological processes.
