Drugs with Senolytic Activity: Prospects and Possible Limitations

The search for and testing of drugs with senolytic activity is a new direction in gerontology. The increasing number of “senescent” cells with age contributes to the development of age-related diseases and chronic non-infectious inflammation. Removing “senescent” cells or suppressing their influence on surrounding tissues seems like a logical step to improve quality of life and possibly prolong it. However, drugs with senolytic and senomorphic activity in model systems induce the development of a number of side effects in clinical trials. In this review, we discuss the main advances in senotherapy, the prospects for the use of senotherapeutics, and the limitations that researchers and clinicians may encounter.
