  Selective inhibition of Trypanosoma brucei GAPDH by 1,3-bisphospho-d-glyceric acid (1,3-diPG) analogues

  摘要：

  Various phosphono-phosphates and diphosphonates were synthesized as 1,3-diphosphoglycerate (1,3-diPG) analogues by using a beta -ketophosphonate, an alpha -fluoro,beta -ketophosphonate or a beta -ketophosphoramidate to mimic the unstable carboxyphosphate part of the natural substrate. The inhibitory effect of these analogues on glyceraldehyde-3-phosphate dehydrogenases (GAPDH) from Trypanosoma brucei (Tb) and rabbit muscle were measured with respect to both substrates, glyceraldehyde-3-phosphate (GAP) and 1,3-diPG. Interestingly, all 1,5-diphosphono,2-oxopentanes without substitution at the C-3 position selectively inhibit the Tb GAPDH with respect to 1,3-diPG and are without effect on Rm GAPDH. All 1-phospho,3-oxo,4-phosphonobutanes show themselves to be non-selective inhibitors either with regard to substrates or organisms, but they will be of a great interest as 1,3-diPG stable models for structural studies of co-crystals with GAPDHs.

• A Convenient Synthesis of Dibenzyl α,α-Difluoromethyl-β-ketophosphonates

  The first synthesis of dibenzyl α,α-difluoro-β-ketophosphonates has been accomplished by an original fluorination reaction, namely addition of the F+ ion to the enolate form of the corresponding dibenzyl β-ketophosphonate. After an easy cleavage of the benzyloxy protecting groups on the phosphorus atom, α-fluoro-β-ketophosphonic acids were subsequently obtained as stable carboxyphosphate mimics. This

  α,α-二氟-β-酮膦酸二苄酯的首次合成是通过原始氟化反应完成的，即将 F+ 离子加成到相应的 β-酮膦酸二苄酯的烯醇化物形式中。在磷原子上的苄氧基保护基团容易裂解后，随后获得 α-氟-β-酮膦酸作为稳定的羧基磷酸酯模拟物。这种方法能够将 α,α-二氟-β-酮膦酸酯部分引入多官能化分子中，从而使之前描述的二乙基膦酸酯路线不再适用。此外，对它们在中性和碱性条件下的稳定性的研究表明，酮-烯醇平衡在这些分子的分解途径中的重要性。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
