Sirtuin 6. Sirtuin 6 ( SIRT6 or Sirt6) is a stress responsive protein deacetylase and mono-ADP ribosyltransferase enzyme encoded by the SIRT6 gene. [5] [6] [7] In laboratory research, SIRT6 appears to function in multiple molecular pathways related to aging, including DNA repair, telomere maintenance, glycolysis and inflammation. [5] SIRT6 is ...
Sirtuin-activating compound. Sirtuin-activating compounds ( STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases. [1]
Sirtuin. Sirtuins are a family of signaling proteins involved in metabolic regulation. [2] [3] They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. [2] Chemically, sirtuins are a class of proteins that possess either mono- ADP-ribosyltransferase or deacylase activity, including ...
Calorie restriction mimetics (CRM), also known as energy restriction mimetics, are a hypothetical class of dietary supplements or drug candidates that would, in principle, mimic the substantial anti-aging effects that calorie restriction (CR) has on many laboratory animals and humans. CR is defined as a reduction in calorie intake of 20% (mild ...
SRT-1720. SRT-1720 is an experimental drug that was studied by Sirtris Pharmaceuticals intended as a small-molecule activator of the sirtuin subtype SIRT1. The compound has been studied in animals, but safety and efficacy in humans have not been established.
Bar Ilan University. Haim Cohen ( Hebrew: חיים כהן; born April 12, 1968) is an Israeli scientist. He is full professor at the Faculty of Life Sciences [1] at Bar Ilan University [2] who studies the molecular mechanisms that determine the rate of aging. Cohen researches longevity [3] and healthy aging. He is the founder and director of ...
CobB is a bacterial protein that belongs to the sirtuin family, a broadly conserved family of NAD+ -dependent protein deacetylases. [2] [3] To further this, CobB is found in the Sir2 Family protein deacetylase, which is in control of energy metabolism, chemotaxis, and DNA supercoiling in many bacteria. [4] CobB does contain a sequence length of ...
SRT-2104. SRT-2104 is an experimental drug that was studied by Sirtris Pharmaceuticals as a small-molecule activator of the sirtuin subtype SIRT1. The compound progressed to Phase II human trials for Type II diabetes before development was discontinued, however it continues to be widely used in animal research into the functions of SIRT1.
