New synthetic routes towards the natural product psammaplin A were developed with the particular view to preparing diverse analogues for biological assessment. These routes utilize cheap and commercially available starting materials, and allowed access to psammaplin A analogues not accessible via currently reported methods. Preliminary biological studies revealed these compounds to be the most potent non peptidic inhibitors of the enzyme histone deacetylase 1 (HDAC1, class I) discovered so far. Interestingly, psammaplin A and our synthetic analogues show class I selectivity in vitro, an important feature for the design and synthesis of future isoform selective inhibitors.
开发了新的合成路线以制备天然产物海绵抑素A(psammaplin A)及其多样化的类似物,这些类似物用于生物学评估。这些路线采用廉价且商业可获得的起始原料,并能合成目前报道方法难以获得的psammaplin A类似物。初步生物学研究表明,这些化合物是目前所发现的最强效的非肽类组蛋白去乙酰化酶1(HDAC1,I类)抑制剂。有趣的是,psammaplin A及其我们的合成类似物在体外显示出I类选择性,这对于设计和合成未来同工型选择性抑制剂具有重要意义。
