A Glycoconjugated SIRT2 Inhibitor with Aqueous Solubility Allows Structure-Based Design of SIRT2 Inhibitors

Small molecule inhibitors for SIRT2, part of the sirtuin group of nicotinamide adenine dinucleotide-dependent protein lysine deacylases, have proven promise for cancer and neurodegenerative illnesses. Developing SIRT2-selective inhibitors with better medicinal qualities is essential to help realize the therapeutic potential of targeting SIRT2. Among the best SIRT2-selective inhibitors reported is really a thiomyristoyl lysine compound known as TM, which demonstrated promising anticancer activity in mouse models with little toxicity to normalcy cells. The primary limitations of TM, however, would be the low aqueous solubility and insufficient X-ray very structures to assist future drug design. Here, we designed and synthesized a glucose-conjugated TM (glucose-TM) analog with superior aqueous solubility. Although glucose-TM isn’t cell permeable, the superb aqueous solubility permitted us to acquire a very structure of SIRT2 in complex by using it. The dwelling enabled us to create several new TM analogs, one of these, NH4-6, demonstrated superior water solubility and anticancer activity in cell culture. The outcomes of those studies provided important insights which will further fuel the long run growth and development of improved SIRT2 inhibitors as promising therapeutics for the treatment of cancer and neurodegeneration.
