the individual β,γ-CHF-ATP stereoisomers 12a and 12b is reported. Configurationally differing solely by the orientation of the C–F fluorine, 12a and 12b have discrete 31P (202 MHz, pH 10.9, ΔδPα 6 Hz, ΔδPβ 4 Hz) and 19F NMR (470 MHz, pH 9.8, ΔδF 25 Hz) spectral signatures and exhibit a 6-fold difference in IC50 values for c-Src kinase, attributed to a unique interaction of the (S)-fluorine of bound
报道了单个β,γ-CHF-ATP立体异构体12a和12b的首次制备。构型上由C-F氟,的取向完全不同12A和12B具有离散31 P(202兆赫,pH值10.9,Δδ Pα 6赫兹,Δδ Pβ 4赫兹)和19 F NMR(470兆赫,pH值9.8,Δδ ˚F 25 Hz)的光谱特征,并显示c-Src激酶的IC 50值有6倍的差异,这归因于结合位点12b的(S)氟与活性位点R388的独特相互作用。
