Synthesis And Biological Evaluation

A new convergent chemoenzymatic synthesis strategy has been established to efficiently synthesize a mimetic of structurally well-defined heparan sulfate proteoglycan syndecan-1 glyco-polypeptide at a milligram scale to enable biological studies.

Synthesis And Biological Evaluation

The lipoxazolidinone family of marine natural products, with an unusual 4-oxazolidinone heterocycle at their core, represents a new scaffold for antimicrobial discovery; however, questions regarding their mechanism of action and high lipophilicity have likely slowed follow-up studies. Herein, we report the first synthesis of lipoxazolidinone A, 15 structural analogs to explore its active pharmacophore, and initial resistance and mechanism of action studies. These results suggest that 4-oxazolidinones are valuable scaffolds for antimicrobial development and reveal simplified lead compounds for further optimization.
