Chemical transformations that yield compounds with distinct activity profiles.

Area of Science:

• Medicinal Chemistry
• Computational Chemistry
• Drug Discovery

Background:

• Understanding chemical transformations is key to designing novel therapeutics.
• Biological activity profiles of compounds guide drug development efforts.

Purpose of the Study:

• To systematically identify chemical transformations that yield compounds with distinct biological activity profiles.
• To analyze matched molecular pairs (MMPs) for compounds active against human targets.

Main Methods:

• Generated activity profiles for approximately 42,000 compounds active against human targets.
• Identified all possible matched molecular pairs (MMPs) for compounds with unique, multi-target activity profiles.
• Isolated and cataloged over 300 nonredundant chemical transformations from ~37,500 MMPs.

Main Results:

• More than 300 nonredundant chemical transformations were identified that result in compounds with distinct biological activity profiles.
• These transformations were not found in compounds with overlapping activity profiles.
• Prioritized transformations often involved complex ring systems and covered multiple targets.

Conclusions:

• The study provides a ranked list of chemical transformations that can switch biological activity profiles.
• These findings aid in compound design by highlighting transformations that generate novel activity.
• The cataloged transformations are valuable resources for medicinal chemists and drug designers.
