SRT-2183 is a drug in development by Sirtris Pharmaceuticals intended as a small-molecule activator of the sirtuin subtype SIRT1. It has similar activity in animal studies to another SIRT1 activator SRT-1720, but is closer in potency to resveratrol. In animal studies it was found to improve insulin sensitivity and lower plasma glucose levels in fat, muscle and liver tissue, and increased mitochondrial and metabolic function. [1] However, the claim that SRT-2183 is a SIRT1 activator has been questioned [2] and further defended. [3]
Sirtuins are a family of signaling proteins involved in metabolic regulation. They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. Chemically, sirtuins are a class of proteins that possess either mono-ADP-ribosyltransferase or deacylase activity, including deacetylase, desuccinylase, demalonylase, demyristoylase and depalmitoylase activity. The name Sir2 comes from the yeast gene 'silent mating-type information regulation 2', the gene responsible for cellular regulation in yeast.
Signal transducer and activator of transcription 2 is a protein that in humans is encoded by the STAT2 gene. It is a member of the STAT protein family. This protein is critical to the biological response of type I interferons (IFNs). STAT2 sequence identity between mouse and human is only 68%.
IKK-β also known as inhibitor of nuclear factor kappa-B kinase subunit beta is a protein that in humans is encoded by the IKBKB gene.
Phospholipase D1 (PLD1) is an enzyme that in humans is encoded by the PLD1 gene, though analogues are found in plants, fungi, prokaryotes, and even viruses.
Phospholipase D2 is an enzyme that in humans is encoded by the PLD2 gene.
MAP kinase-activated protein kinase 2 is an enzyme that in humans is encoded by the MAPKAPK2 gene.
B-cell lymphoma 3-encoded protein is a protein that in humans is encoded by the BCL3 gene.
NK2 homeobox 1 (NKX2-1), also known as thyroid transcription factor 1 (TTF-1), is a protein which in humans is encoded by the NKX2-1 gene.
Sirtuin 1, also known as NAD-dependent deacetylase sirtuin-1, is a protein that in humans is encoded by the SIRT1 gene.
NAD-dependent deacetylase sirtuin 2 is an enzyme that in humans is encoded by the SIRT2 gene. SIRT2 is an NAD+ -dependent deacetylase. Studies of this protein have often been divergent, highlighting the dependence of pleiotropic effects of SIRT2 on cellular context. The natural polyphenol resveratrol is known to exert opposite actions on neural cells according to their normal or cancerous status. Similar to other sirtuin family members, SIRT2 displays a ubiquitous distribution. SIRT2 is expressed in a wide range of tissues and organs and has been detected particularly in metabolically relevant tissues, including the brain, muscle, liver, testes, pancreas, kidney, and adipose tissue of mice. Of note, SIRT2 expression is much higher in the brain than all other organs studied, particularly in the cortex, striatum, hippocampus, and spinal cord.
Sirtuin 6 is a stress responsive protein deacetylase and mono-ADP ribosyltransferase enzyme encoded by the SIRT6 gene. In laboratory research, SIRT6 appears to function in multiple molecular pathways related to aging, including DNA repair, telomere maintenance, glycolysis and inflammation. SIRT6 is member of the mammalian sirtuin family of proteins, which are homologs to the yeast Sir2 protein.
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.
Sirtris Pharmaceuticals, Inc. was a biotechnology company based in Cambridge, MA that developed therapies for type 2 diabetes, cancer, and other diseases. Conceived in 2004 by Harvard University biologist David Sinclair and serial entrepreneur Andrew Perlman, and founded that year by Sinclair and Perlman, along with Christoph Westphal, Richard Aldrich, Richard Pops, and Paul Schimmel, the company was focused on developing Sinclair's research into activators of sirtuins, work that began in the laboratory of Leonard P. Guarente where Sinclair worked as a post-doc before starting his own lab.
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.
SRT-1460 is a drug in development by Sirtris Pharmaceuticals intended as a small-molecule activator of the sirtuin subtype SIRT1. It has similar activity in animal studies to the known SIRT1 activator resveratrol, but is closer in potency to SRT-1720. In animal studies it was found to improve insulin sensitivity and lower plasma glucose levels in fat, muscle and liver tissue, and increased mitochondrial and metabolic function. However, the claim that SRT1460 is a SIRT1 activator has been questioned and further defended.
C16 is a drug which acts as a selective inhibitor of the enzyme double-stranded RNA-dependent protein kinase (PKR). It has been shown to effectively inhibit PKR function in vivo and has neuroprotective and nootropic effects in animal studies.
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.
SRT-3025 is an experimental drug that was studied by Sirtris Pharmaceuticals as a small-molecule activator of the sirtuin subtype SIRT1. It has been investigated as a potential treatment for osteoporosis, and anemia.
STAC-9 is an experimental drug that was developed by GlaxoSmithKline as a small-molecule activator of the sirtuin subtype SIRT1, with potential applications in the treatment of diabetes.
