4'-carboxymethyloxy-3'-phosphonophenylalanine (Cpp) has been designed and incorporated into a series of nonpeptide inhibitors of the SH2 domain of pp60(c-Src) (Src) tyrosine kinase. A 2.2 A X-ray crystal structure of 1a bound to a mutant form of Lck SH2 domain provides insight regarding the structure-activity relationships and supports the design concept of this new pTyr mimetic.
已设计出新型的
磷酸酪氨酸(pTyr)模拟4'-羧甲氧基-3'-膦酰苯丙
氨酸(Cpp),并结合到了pp60(c-Src)(Src)
酪氨酸激酶SH2域的一系列非肽
抑制剂中。与突变形式的Lck SH2结构域结合的1a的2.2 X射线晶体结构提供了有关结构-活性关系的见解,并支持这种新的pTyr模拟物的设计概念。
