  描述：

  2-(formyl)-6,7-dihydrothieno[3,2-c]-5(4H)-pyridine hydrochloride 在 乙醚 、 三乙胺 、 N,N-二异丙基乙胺 、 magnesium bromide 作用下， 以 四氢呋喃 、 N,N-二甲基甲酰胺 、 乙腈 为溶剂， 反应 47.0h， 生成 4-nitrobenzyl-6-[(acetyloxy)-(5-(4-methoxybenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridin-2-yl)methyl]-6-bromo-7-oxo-4-thia-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate

  Structure-Activity Relationship of 6-Methylidene Penems Bearing 6,5 Bicyclic Heterocycles as Broad-Spectrum β-Lactamase Inhibitors:  Evidence for 1,4-Thiazepine Intermediates with C7 R Stereochemistry by Computational Methods

  摘要：

  The design and synthesis of a series of 6-methylidene penems containing [6,5]-fused bicycles (thiophene, imidazole, or pyrazle-fused system) as novel class A, B, and C beta-lactamase inhibitors is described. These penems proved to be potent inhibitors of the TEM-1 (class A) and AmpC (class C) beta-lactamases and less so against the class B metallo-beta-lactamase CcrA. Their in vitro and in vivo activities in combination with piperacillin are discussed. On the basis of the crystallographic structures of a serine-bound reaction intermediate of 2 with SHV-1 (class A) and GC1 (class C) enzymes, compounds 14a-1 were designed and synthesized. Penems are proposed to form a seven-membered 1,4 thiazepine ring in both class A and C beta-lactamases. The interaction energy calculation for the enzyme-bound intermediates favor the formation of the C7 R enantiomer over the S enantiomer of the 1,4-thiazepine in both beta-lactamases, which is consistent with those obtained from the crystal structure of 2 with SHV-1 and GC1.

  This invention relates to certain bicyclic 6-alkylidene penems which act as a inhibitor of class-D enzymes. β-Lactamases hydrolyze β-lactam antibiotics, and as such serve as the primary cause of bacterial resistance. The compounds of the present invention when combined with β-lactam antibiotics will provide an effective treatment against life threatening bacterial infections. In accordance with the present invention there are provided compounds of general formula I or a pharmaceutically acceptable salt or in vivo hydrolyzable ester R 5 thereof: wherein: One of A and B denotes hydrogen and the other an optionally substituted fused bicyclic heteroaryl group; and X═O or S.
