Natural products significantly impact drug discovery, but high-throughput screening (HTS) challenges their use. A new lipophilicity-based strategy aims to make natural product leads compatible with modern drug discovery timelines.

Area of Science:

  • Medicinal Chemistry
  • Natural Product Chemistry
  • Drug Discovery

Background:

  • Natural products (NPs) and their analogues constitute approximately 34% of new chemical entities (NCEs) introduced between 1981 and 2010.
  • The popularity of high-throughput screening (HTS) of pure compound libraries has led to a decline in NP-based drug discovery over the past two decades.
  • A key challenge for NP drug discovery within the HTS paradigm is the lack of a strategy to ensure NP extracts or fractions are compliant with lead- and drug-like chemical properties.

Purpose of the Study:

  • To address the imbalance in drug discovery approaches by developing a strategy for natural product drug discovery.
  • To enable the front-loading of chemical constituents from natural product extracts or fractions to align with lead- and drug-like chemical space requirements.
  • To facilitate the identification of natural product leads within timelines compatible with current HTS methodologies.

Main Methods:

  • Development of a strategy based on lipophilicity, quantified by clog P.
  • Integration of advances in isolation and structural elucidation techniques.
  • Application of the lipophilicity-based approach to natural product extracts and fractions.

Main Results:

  • The developed strategy allows for the assessment and optimization of natural product constituents for drug-likeness.
  • The approach facilitates the identification of natural product leads.
  • Timelines for obtaining natural product leads are made compatible with those of pure compound screening.

Conclusions:

  • A novel lipophilicity-based strategy can overcome impediments in natural product drug discovery within the HTS framework.
  • This approach enhances the utility of natural products as starting points for drug development.
  • The strategy supports efficient and timely identification of drug-like natural product leads, revitalizing the role of NPs in pharmaceutical research.
