  Potent non-peptidyl inhibitors of protein tyrosine phosphatase 1B

  摘要：

  The development of inhibitors of protein tyrosine phosphatases (PTPs) has recently been the subject of intensive investigation due to their potential as chemotherapeutics and as tools for studying signal transduction pathways. Here we report the evaluation of a variety of small molecule, non-peptidyl inhibitors of protein tyrosine phosphatase 1B (PTP1B), bearing the alpha,alpha-difluoromethylenephosphonic acid (DFMP) group, a non-hydrolyzable phosphate mimetic. A series of phenyl derivatives bearing a single DFMP group were initially surveyed. In general, these were not significantly more potent inhibitors than the parent compound, alpha,alpha-difluorobenzylphosphonic acid, with the exception being the meta-phenyl substituted species which decreased the IC50 by approximately 17-fold relative to alpha,alpha-difluorobenzylphosphonic acid. However, certain compounds bearing two DFMP moieties were very potent inhibitors. Some of these are among the most potent small molecule inhibitors of any PTP reported to date with the best one exhibiting a K-i of 1.5 mu M. The structural basis for these results are discussed. One of the bis-DFMP inhibitors was examined in detail and it was found that the fluorines were essential for potent inhibition. Inhibition was independent of pH between pH 5.5-7.2 suggesting that both the mono and dianionic forms of the individual DFMP groups bind equally well. The trends observed in the inhibitory potency of these compounds with PTP1B were very similar to the trends observed by other workers on the K-m's of the analogous phenylphosphate substrates with rat PTP1. This indicates that studies of non-peptidyl substrates with rat PTP1 can be used as a guide for the development of human PTP1B inhibitors. (C) 1998 Elsevier Science Ltd. All rights reserved.

  用N-氟苯磺酰亚胺通过苄基膦酸酯的α-碳负离子的亲电氟化反应合成芳基（二氟亚甲基膦酸酯）

  摘要：

  已经研究了多种苄基膦酸酯与N-氟苯磺酰亚胺的亲电子氟化。在一系列官能团如硝基，溴，酮，酯，苯基和醚基的存在下，氟化反应进行得很好。也可以制备含有两个α，α-二氟亚甲基膦酸酯基的苯基和联苯衍生物。该方法与甲基或乙基膦酸酯相容，但是与叔丁基酯或在对位处含有另外的苄基部分的苄基膦酸酯不相容。

The procedure allows the conversion of aryl diazonium salts, as well as aryl, heteroaryl, vinyl and alkynyl iodonium salts, into the corresponding fluorinated molecules at room temperature. Mechanistic studies were performed to gain a better understanding of the reaction pathway. Under similar conditions, vinyl and aryl iodides, allyl halides, and benzyl bromides were also functionalised
