SRT2104 (GSK2245840) Usage And Synthesis

Biological Activity

srt2104 (gsk2245840) is a selective sirt1 activator involved in the regulation of energy homeostasis. sirt1, also known as nad-dependent deacetylase sirtuin-1, is a member of the sirtuin family of proteins.

in vitro

in c2c12 myoblasts stably transfected with small hairpin rna to knock-down sirt1, srt2104 increased ap activity, a marker for osteogenic differentiation. this effect was totally dependent on sirt1 expression [1].

in vivo

in male c57bl/6j mice, administration of srt2104 (100 mg/kg, p.o.) extended both mean and maximal lifespan of mice fed a standard diet, and enhanced bone mineral density, motor coordination, and insulin sensitivity and decreased inflammation. short-term srt2104 administration preserved bone and muscle mass in an experimental model of atrophy [1]. in male n171-82q hd mice with huntington's disease, srt2104 (diet containing 0.5% srt2104) effectively penetrated the blood-brain barrier, attenuated brain atrophy, improved motor function, and extended survival [2].
