Senolytic

A senolytic (from the words senescence and -lytic, "destroying") is among a class of small molecules under basic research to determine if they can selectively induce death of senescent cells and improve health in humans.[1] A goal of this research is to discover or develop agents to delay, prevent, alleviate, or reverse age-related diseases.[2][3] A related concept is "senostatic", which means to suppress senescence.

Research

Possible senolytic agents are under preliminary research, including some which are in early-stage human trials.[4] The majority of candidate senolytic compounds are repurposed anti-cancer molecules, such as the chemotherapeutic drug dasatinib and the experimental small molecule navitoclax.[5][6]

Senolytic candidates
  • FOXO4-related peptides. FOXO4 can bind with p53 protein to induce cellular senescence.[7] A peptide competing with FOXO4 can act as a senolytic by excluding p53 from the nucleus.[7]
  • Inhibitors of USP7 (Ubiquitin-specific processing protease 7)[11]
gollark: Ah yes, of course, they would want to keep its evil 5G nature secret until the world was ready.
gollark: There's no iPhone 5G, only the 5, 5S and 5C because Apple can't be consistent.
gollark: Companies were invented by company companies to sell more companies!
gollark: Which would probably introduce its own problems.
gollark: Or have tiny holes in dies to run nonconductive liquid through or something.
