Novel hydroxyphosphonate inhibitors of CD-45 tyrosine phosphatase
摘要:
CD-45 tyrosine phosphatase [E.C. 3.1.3.48] is an important player in the regulation of cell activation and proliferation in hematopoetic cells. As part of a program in immune response modulation, we prepared the first series of small organic molecule inhibitors of CD-45. The preparation and in vitro screening of these hydroxyphosphonates is described herein. (C) 1997 Elsevier Science Ltd.

We report a new environmentally-benign, convenient, and facile methodology for the synthesis of α-hydroxyphosphonates from an aromatic/heteroaromatic aldehyde with triethylphosphite in the presence of potassium dihydrogen phosphate (KH2PO4) under ultrasound-assisted solvent-free conditions. Furthermore, a series of compounds were synthesized and characterized by melting point, EI-MS, NMR, and IR tools
我们报告了在超声辅助无溶剂条件下,在磷酸二氢钾(KH 2 PO 4)存在下,由亚磷酸三乙酯从芳族/杂芳族醛与亚磷酸三乙酯合成α-羟基膦酸酯的新型环保,便捷,简便的方法。此外,合成了一系列化合物,并通过熔点,EI-MS,NMR和IR工具进行了表征。从经济的角度来看,利用容易的反应条件,分离和纯化使这种操作非常有趣。
