  摘要：

  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.
