  New Type of Metalloproteinase Inhibitor:  Design and Synthesis of New Phosphonamide-Based Hydroxamic Acids

  摘要：

  A series of phosphonamide-based hydroxamate derivatives were synthesized, and the inhibitory activities were evaluated against various metalloproteinases in order to clarify its selectivity profile. Among the four diastereomeric isomers resulting from the chirality at the C-3 and P atoms, the compound with a (R,R)-configuration both at the C-3 position and the phosphorus atom was found to be potently active, while the other diastereomeric isomers were almost inactive. A number of (R,R)-compounds synthesized here exhibited broad spectrum activities with nanomolar K-i values against MMP-1, -3, -9, and TACE and also showed nanomolar IC50 values against HB-EGF shedding in a cell-based inhibition assay. The modeling study using X-ray structure of MMP-3 suggested the possible binding mode of the phosphonamide-based inhibitors.

  There is described a process for preparing an enamine of formula (IX): where R2 is a carboxylic acid protecting group and R3 is the residue of a carboxylic acid derived acyl group and where R5 and R6 are the same or different C1-4 alkyl or C7-10 aralkyl groups; or taken together with the adjacent nitrogen atom form a heterocyclic ring containing from 4 to 8 carbon atoms and optionally a further heteroatom selected from oxygen and nitrogen; by reacting a compound of formula (XII) : with an amine of formula HNR5R6, the reactant of formula (XII) being prepared by reaction of an appropriate enol derivative with a phosphorus reagent. The enamines of formula (IX) are useful in the preparation of 3-hydroxycephalosporins.

  本发明描述了一种制备式(IX)烯胺的工艺： 其中 R2 是羧酸保护基，R3 是羧酸衍生酰基的残基，R5 和 R6 是相同或不同的 C1-4 烷基或 C7-10 芳烷基；或与相邻的氮原子一起形成含有 4 至 8 个碳原子和任选地另一个选自氧和氮的杂原子的杂环；通过使式 (XII) ： 与式 HNR5R6 的胺反应，式 (XII) 的反应物通过适当的烯醇衍生物与磷试剂反应制备。式（IX）的烯胺可用于制备 3-羟基头孢菌素。
