Researchers developed new bryostatin analogues with C13 modifications. This diversification strategy allows for tuning biological activity, offering potential therapeutic applications.
Area of Science:
- Medicinal Chemistry
- Organic Synthesis
- Pharmacology
Background:
- Bryostatins are a class of natural products with significant biological activity.
- Developing synthetic analogues is crucial for understanding structure-activity relationships and therapeutic potential.
- Late-stage diversification strategies are valuable for rapidly generating compound libraries.
Purpose of the Study:
- To design and synthesize novel C13-diversified bryostatin analogues.
- To establish a general synthetic strategy for late-stage diversification of the bryostatin scaffold.
- To evaluate the biological activity of the synthesized analogues.
Main Methods:
- Utilized a Prins macrocyclization-nucleophilic trapping cascade for synthesis.
- Employed late-stage diversification at the C13 position.
- Conducted in vitro biological evaluation of selected library members.
Main Results:
- Successfully synthesized a novel class of C13-diversified bryostatin analogues.
- Demonstrated the utility of a Prins macrocyclization-nucleophilic trapping cascade for diversification.
- Identified that C13 modifications can modulate biological activity.
Conclusions:
- The C13 position serves as a key diversification handle in bryostatin analogues.
- The developed strategy enables the regulation of biological activity through scaffold modification.
- These findings contribute to the development of new bryostatin-based therapeutics.

Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn...
