distinguishing examples, Largazole and Psammaplin A, which possess macrocyclic depsipeptide and simple linear amide scaffold respectively, we designed one novel molecular hybrid by replacing the alkene moiety in Largazole with a semirigid amide bond. This hybrid compound has been synthesized from l-malic acid in 10 steps with an overall yield of 7%. The preliminary biological assays suggest that the replacement
HDAC(组蛋白去乙酰化酶)抑制剂的重要一类是具有结构多样性的含硫海洋天然产物。受两个分别具有大环depsipeptide和简单线性酰胺骨架的结构上不同的实例Largazole和Psammaplin A的启发,我们通过用半刚性酰胺键取代Largazole中的烯烃部分,设计了一种新型分子杂合物。该杂合化合物已经由1-苹果酸分十步合成,总收率为7%。初步的生物学分析表明,用酰胺键取代反式烯烃部分将对HDAC的抑制作用产生不利影响。
