Objective:

The article presents industry contributors’ views on the continuing role of small molecules alongside newer drug modalities.

Approach:
  • Perspectives: The article presents comments from five contributors in biotechnology, drug discovery, and computational science.
  • Topics: Contributors discuss oral administration, tissue penetration, intracellular targets, advances in medicinal chemistry and computational methods, protein degraders and macrocycles, manufacturing, and health-system fit.
Key Findings:
  • Contributors describe small molecules as continuing to have roles alongside cell therapies, biologics, and RNA-based approaches, with modality choice depending on biological and patient needs.
  • Contributors cite oral administration as a potential convenience advantage, particularly for people receiving long-term treatment.
  • Contributors describe small molecules as useful for intracellular targets and cite tissue penetration, including access to the central nervous system, as an advantage.
  • Contributors discuss advances in medicinal chemistry, computational methods, protein degradation, and work beyond traditional rule-of-five limits as expanding small-molecule research.
  • Contributors cite relatively straightforward or scalable manufacturing and the fit of oral medicines with established health-care and reimbursement systems.
Interpretation:

The contributors present small molecules as one modality among several, with their suitability depending on the target and patient needs.

Limitations:
  • The supplied context consists of attributed perspectives from industry contributors; it does not provide independent comparative clinical evidence.
  • Claims about convenience, access, manufacturing, and modality advantages are presented by contributors and are not independently evaluated in the supplied context.
Conclusion:

The contributors describe small molecules as continuing to have a role and discuss advances they believe are expanding the scope of small-molecule research.
