Molecular dynamics simulations based on the structure of the Grb7 SH2 domain in complex with the ErbB2 phosphorylated peptide pTyr1139 have suggested that β-[1-(4-malonyl)naphthyl]-L-alanine (L-mNal) may be accommodated in the pTyr binding pocket and offer additional beneficial interactions. Therefore, this compound and its analog β-[1-(4-malonylmethyl)naphthyl]-L-alanine (L-mmNal), which are newnon-hydrolysable
基于与 ErbB2 磷酸化肽 pTyr1139 复合的 Grb7 SH2 结构域结构的分子动力学模拟表明,β-[1-(4-丙二酰)萘基]-L-丙氨酸 (L-mNal) 可容纳在 pTyr 中绑定口袋并提供额外的有益相互作用。因此,该化合物及其类似物 β-[1-(4-丙二酰甲基)萘基]-L-丙氨酸 (L-mmNal) 是新型的不可水解磷酸酪氨酸模拟物,已通过相应的前手性烯酰胺的催化不对称氢化制备具有优异的对映选择性。这些化合物及其脱氢衍生物显示出有趣的荧光特性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
