α-Azido Bisphosphonates: Synthesis and Nucleotide Analogues
摘要:
The first examples of alpha-azido bisphosphonates [(RO)(2) P(O)](2)CXN3 (1, R = i-Pr, X = Me; 2, R = i-Pr, X = H; 3, R = H, X = Me; 4, R = H, X = H) and corresponding beta,gamma-CXN3 dGTP (5-6) and alpha/beta-CXN3 dATP (7-8) analogues are described. The individual diastereomers of 7 (7a/b) were obtained by HPLC separation of the dADP synthetic precursor (14a/b).

adenine nucleotide translocase. Inhibition of the latter is due to formation in cells of analogs of ATP: the isopentenyl ester of ATP (ApppI) or an AppXp-type analog of ATP, such as AMP-clodronate (AppCCl2p). We screened both ApppI as well as AppCCl2p against a panel of 369 kinases finding potent inhibition of some tyrosine kinases by AppCCl2p, attributable to formation of a strong hydrogen bond between
双膦酸盐是一类主要用于治疗骨质疏松症、佩吉特病和癌症的药物。已经提出它们通过抑制一种或多种靶标起作用,包括蛋白质异戊二烯化、表皮生长因子受体或腺嘌呤核苷酸移位酶。后者的抑制是由于 ATP 类似物在细胞中的形成:ATP 的异戊烯酯 (ApppI) 或 ATP 的 AppXp 型类似物,例如 AMP-氯膦酸盐 (AppCCl2p)。我们针对一组 369 种激酶筛选了 ApppI 和 AppCCl2p,发现 AppCCl2p 能有效抑制某些酪氨酸激酶,这归因于酪氨酸和末端膦酸酯之间形成强氢键。然后我们合成了在细胞中转化为其他 ATP 类似物的双膦酸盐前体药物,发现了抑制细胞信号通路的低 nM 激酶抑制剂。
