Understanding the Structural Complexity
At its core, FK228 is a bicyclic depsipeptide that stands apart from linear synthetic alternatives. The molecule features a complex 16-membered cyclic depsipeptide structure, which is integral to its biological behavior. When analyzing the depsipeptide HDAC landscape, it is important to recognize that this molecule acts as a natural prodrug. It requires intracellular reduc Total Synthesis of FK228, the Depsipeptide Histone tion to become active, a mechanism that highlights its high degree of specificity.
