New RORγt agonists were developed for cancer immunotherapy. These novel compounds show enhanced RORγt agonism, offering potential for small molecule therapeutics targeting Th17 cell responses.
Area of Science:
- Immunology
- Medicinal Chemistry
- Molecular Biology
Background:
- Retinoic acid receptor-related orphan receptor gamma-t (RORγt) is a key transcription factor for Th17 cell development.
- Th17 cells exhibit antitumor properties by activating CD8+ T cells.
- RORγt agonists are explored as potential cancer immunotherapies.
Purpose of the Study:
- To design and synthesize novel RORγt agonists.
- To improve chemical properties and biological responses of RORγt agonists.
- To identify potent small molecule therapeutics for cancer immunotherapy.
Main Methods:
- Structure-based drug design utilizing a known RORγt agonist and its co-crystal structure.
- Synthesis of a series of novel tertiary amines.
- Biological evaluation of synthesized compounds at target-based and cell-based levels.
Main Results:
- Identification of optimal moieties with enhanced chemical properties and biological activity.
- Discovery of novel RORγt agonists, exemplified by compound 8b.
- Compound 8b demonstrated significantly elevated RORγt agonism in assays.
Conclusions:
- Novel RORγt agonists with improved properties were successfully developed.
- Compound 8b represents a promising candidate for further development.
- This research provides valuable structural insights for optimizing RORγt agonists in cancer immunotherapy.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...
