Light-activatable ("caged") proteins have been used to correlate, with exquisite temporal and spatial control, intracellular biochemical action with global cellular behavior. However, the chemical or genetic construction of caged proteins is nontrivial, with subsequent laborious introduction into living cells, potentially problematic competition with natural endogenous counterparts, and challenging intracellular incorporation at levels equivalent to the natural enzymes. We describe the design, synthesis, and characterization of small molecular equivalents of a caged Src kinase. These compounds are easy to prepare and function by inhibiting the action of the natural unmodified enzyme.
光可激活(“笼化”)蛋白已被用于在精确的时间和空间控制下,将细胞内生化作用与整体细胞行为相关联。然而,笼化蛋白的化学或基因构建并非易事,随后将其费力地导入活细胞中,可能会与天然内源性对应物产生有问题的竞争,并且在与天然酶相当的水平上进行细胞内掺入也具有挑战性。我们描述了一种笼化Src激酶的小分子类似物的设计、合成和表征。这些化合物易于制备,并且通过抑制天然未修饰酶的作用来发挥功能。
