Inhibitors of sirtuin-2 deacetylase (SIRT2) have been shown to be protective in various models of Huntington’s disease (HD) by decreasing polyglutamine aggregation, a hallmark of HD pathol. The present study was directed at optimizing the potency of SIRT2 inhibitors containing the neuroprotective sulfobenzoic acid scaffold and improving their pharmacol. To achieve that goal, 176 analogs were designed, synthesized, and tested in deacetylation assays against the activities of major human sirtuins SIRT1-3. This screen yielded 15 compounds with enhanced potency for SIRT2 inhibition and 11 compounds having SIRT2 inhibition equal to reference compound AK-1. The newly synthesized compounds also demonstrated higher SIRT2 selectivity over SIRT1 and SIRT3. These candidates were subjected to a dose-response bioactivity assay, measuring an increase in α-tubulin K40 acetylation in two neuronal cell lines, which yielded five compounds bioactive in both cell lines and eight compounds bioactive in at least one of the cell lines tested. These bioactive compounds were subsequently tested in a tertiary polyglutamine aggregation assay, which identified five inhibitors. ADME properties of the bioactive SIRT2 inhibitors (e.g., I) were assessed, which revealed a significant improvement of the pharmacol. properties of the new entities, reaching closer to the goal of a clin.-viable candidate. The experimental process involved the reaction of 5-Bromothiazol-2-amine(cas: 3034-22-8Application of 3034-22-8)
5-Bromothiazol-2-amine(cas: 3034-22-8) belongs to anime. Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral). With amines, there is extremely rapid inversion in which the two configurations are interconverted.Application of 3034-22-8
