  • Patent number: 11897915
    Abstract: Provided herein are novel sugar derivatives which are intermediates for preparing senolytic agents that selectively kill senescent cells associated with numerous pathologies and diseases, including age-related pathologies and diseases.
    Type: Grant
    Filed: September 13, 2022
    Date of Patent: February 13, 2024
    Assignee: Rubedo Life Sciences, Inc.

  • Publication number: 20230138729
    Abstract: Provided herein are coumarin derivatives of sugar analogs which are used to measure the rate of hydrolysis of these sugar analogs when contacted with a glycosidase. The reactivity of the coumarin derivatives serves as a convenient method for estimating for the rate of hydrolysis of sugar analogs when used a promoiety with cytotoxic drugs to generate senolytic agents with improved selectivity for killing senescent cells.
