Design, Synthesis, and Identification of Silicon Incorporated Oxazolidinone Antibiotics with Improved Brain Exposure
摘要:
Therapeutic options for brain infections caused by pathogens with a reduced sensitivity to drugs are limited. Recent reports on the potential use of linezolid in treating brain infections prompted us to design novel compounds around this scaffold. Herein, we describe the design and synthesis of various oxazolidinone antibiotics with the incorporation of silicon. Our findings in preclinical species suggest that silicon incorporation is highly useful in improving brain exposures. Interestingly, three compounds from this series demonstrated up to a 30-fold higher brain/plasma ratio when compared to linezolid thereby indicating their therapeutic potential in brain associated disorders.

The intermolecularanti-Markovnikovhydroamination of vinylsilanes was achieved utilizing five silyl-substituted ortho-terphenoxide yttrium complexes. The highest activity was observed for the most sterically encumbered triphenylsilyl-substituted complex. Excellent activity and complete anti-Markonikov selectivity were obtained for a variety of benzylic and aliphatic primary and secondary amines. Interestingly
