  4-吡啶酮衍生物作为细菌烯酰-ACP还原酶FabI的新抑制剂。

  摘要：

  细菌FAS提供关键脂肪酸，用于关键细胞组分的组装。其中，FabI是一种烯酰ACP还原酶，可催化细菌FAS的最终和限速步骤。它是选择性抗菌作用的潜在靶标，因为它与哺乳动物酶的整体序列同源性较低。直到今天，已经报道了各种化合物作为细菌FabI抑制性化合物的抑制剂。为了发现新颖的小分子FabI抑制剂，我们首先筛选了化合物库对大肠杆菌FabI的抑制活性。并发现了4-吡啶酮衍生物作为先导化合物。结构优化研究产生了对金黄色葡萄球菌具有强FabI抑制和抗菌活性的4-吡啶酮衍生物7n。

  3-Hydroxy-4-pyrones as Precursors of 4-Methoxy-3-oxidopyridinium Ylides. An Expeditious Entry to Highly Substituted 8-Azabicyclo[3.2.1]octanes

  摘要：

  3-Hydroxy-4-pyridones, which are easily prepared from commercially available 3-hydroxy-4-pyrones, can be readily transformed into 4-methoxy-3-oxidopyridinium ylides by treatment with methyl trifluoromethanesulfonate and subsequent deprotonation with a non-nucleophilic base. These ylides are capable of undergoing cycloaddition to several electron-deficient alkenes, thus allowing the synthesis of highly functionalized azabicyclo[3.2,1]octane moieties. The rich substitution patterns of these frameworks might allow their divergent conversion to a variety of natural and non-natural tropane alkaloids.

  We have prepared a number of complexes of the type cis-MoO₂L₂ where L represents a hydroxypyronato or hydroxypyridinonato ligand. Both the maltol (3-hydroxy-2-methyl-4-pyrone, Hma) and kojic acid (5-hydroxy-2-hydroxymethyl-4-pyrone, Hka) complexes, cis-MoO₂(ma)₂ (1) and cis-MoO₂(ka)₂ (2), have been characterized by X-ray diffraction studies. The pyrone ligands are bound to molybdenum in a cis bidentate fashion via the deprotonated hydroxyl groups and the ketone moieties. Crystals of 1 are orthorhombic, a = 12.107 (1), b = 8.6169 (8), c = 16.472 (1) Å, Z = 4, space group Pca2₁, and those of 2 are monoclinic, a = 8.4591 (5), b = 16.3453 (10), c = 10.2954 (7) Å, β = 103.0320 (10)°, Z = 4, space group P2₁/c. Hydroxypyridinone molybdenum complexes have been prepared for both maltol and kojic acid derivatives with the substituents Me, n-Pr, CH₂Ph, Ph at the ring nitrogen. Crystals of the 3-hydroxy-2-methyl-1-phenyl-4-pyridinone (Hppp) derivative, MoO₂(ppp)₂ (9), are monoclinic, a = 10.9476 (6), b = 13.5353 (9), c = 17.4877 (10) Å, β = 93.465 (4)°, Z = 4, space group P2₁/n. Initial investigations into the effects molybdenum compounds have on diabetic hearts are presented. Both Na₂MoO₄ (used as a control) and 1 were effective in lowering blood glucose and free fatty acid levels. Diabetic rats treated with molybdate showed significant improvements in postischemic cardiac function.Key words: molybdenum, hydroxypyrones, hydroxypyridinones, heart function.
