  • Structural Basis for the Formation of Acylalkylpyrones from Two β-Ketoacyl Units by the Fungal Type III Polyketide Synthase CsyB

    The acylalkylpyrone synthase CsyB from Aspergillus oryzae catalyzes the one-pot formation of the 3-acyl-4-hydroxy-6-alkyl-alpha-pyrone scaffold from acetoacetyl-CoA, fatty acyl-CoA, and malonyl-CoA. This is the first type III polyketide synthase that performs not only the polyketide chain elongation but also the condensation of two beta-ketoacyl units. The crystal structures of wild-type CsyB and its
    米曲霉的酰基烷基吡喃酮合酶CsyB催化由乙酰乙酰辅酶A,脂肪酰基辅酶A和丙二酰辅酶A一锅形成3-酰基-4-羟基-6-烷基-α-吡喃酮支架。这是第一种III型聚酮化合物合酶,不仅可以进行聚酮化合物链的延伸,还可以使两个β-酮酰基单元缩合。野生型CsyB及其I375F和I375W突变体的晶体结构分别以1.7-,2.3-和2.0-A的分辨率解析。晶体结构揭示了一个独特的活性位点结构,该结构具有迄今无法识别的新颖口袋,可容纳乙酰乙酰辅酶A起始物,此外还具有带有Cys-His-Asn催化三联体的常规延伸/环化口袋和用于结合脂肪的长疏水通道酰基链。该结构还表明存在一个假定的亲核水分子,该分子被氢键网络激活,其活性位点中心处有His-377和Cys-155。此外,体外酶反应证实,H2(18)O分子的(18)O原子通过酶法结合到最终产物中。这些观察结果表明,酶反应是通过将乙酰乙酰辅酶A负载到Cys-155
  • Inhibition of human sputum elastase by substituted 2-pyrones. 2
    作者:Luisa Cook、Bela Ternai、Peter Ghosh
    DOI:10.1021/jm00389a010
    日期:1987.6
    Nineteen 4-hydroxy- and 4-methoxy-2-pyrones related to elasnin (I) have been assayed for in vitro inhibition of human sputum elastase (HSE), porcine pancreatic elastase, alpha-chymotrypsin, and trypsin. Inhibition is reported as Ki and Ki'; percentage inhibition was dependent on [S] in a number of cases, making it unsuitable as a measure of relative inhibition. The 3-(1-oxoalkyl)-4-hydroxy-6-alkyl-2-pyrones were found to be most effective, the octyl homologue 11 being the most potent inhibitor (Ki = 4.6 microM, 30 times better than the lead compound). A further reduction in inhibition was observed when the hitherto hydrophobic 6-substituent was substituted by a branched functionality of hydrophilic nature. Conversely, methylation of the 4-hydroxy group of the 6-alkyl-2-pyrones increased inhibitory activity. The mechanism of inhibition varied from pure noncompetitive to mixed type to uncompetitive and was found to be dependent on the pattern of substitution. We believe that the 4-hydroxy-2-pyrone binds to the S4 subsite, with the 6-substituent extending across the S4-S1 subsites and the 3-substituent occupying the S5 subsite. The length of the inhibitor binding region was calculated to be approximately 24 A. None of the hydrophobic compounds were found to have any appreciable inhibition (less than 10%) with porcine pancreatic elastase, bovine alpha-chymotrypsin, and bovine trypsin when tested at the limit of their solubility. The hydrophilic compounds were nonspecific, inhibiting all four enzymes. Dialysis was used to show that the interaction is fully reversible.

    (EN) A compound of formula (III) or physiologically acceptable salts thereof, wherein: Z is a bond, -O- or -NH-; R1 and R3 are independently selected from C5-12 substituted of unsubstituted hydrocarbon radicals; R2 is hydrogen or a C1-5 substituted or unsubstituted hydrocarbon radical; said substituted hydrocarbon radicals are substituted with physiologically innocuous substituents which do not interfere with the binding of said compound with elastase-type enzymes; provided that: when R1 is oxohexyl and R2 is hydrogen, then R3 cannot be pentyl; when R1 is oxoheptyl and R2 is hydrogen, then R3 cannot be hexyl; when R1 is oxononyl and R2 is hydrogen, then R3 cannot be octyl; when R1 is oxodecyl and R2 is hydrogen, then R3 cannot be nonyl; and when R1 is oxododecyl and R2 is hydrogen, then R3 cannot be undecyl. These compounds are potent and specific inhibitor compounds fo elastase-type enzymes, especially for human leucocytic elastase (HLE) and can be expected to be useful in the treatment of elastase-type implicated diseases such as arthritis, tumor growth and emphysema. Production, method of use and pharmaceutical compositions containing these compounds are disclosed.(FR) La présente invention se rapporte à un composé représenté par la formule (III) ou à des sels physiologiquement acceptables dudit composé, où: Z représente une liaison, -O- ou -NH-; R1 et R3 sont choisis séparément parmi des radicaux d'hydrocarbures substitués ou non substitués de 5 à 12 atomes de carbone; R2 représente un hydrogène ou un radical d'hydrocarbures substitués ou non substitués de 1 à 5 atomes de carbone; lesdits radicaux d'hydrocarbures substitués étant substitués par des substituants physiologiquement inoffensifs qui ne perturbent pas la liaison entre ledit composé et les enzymes du type élastase; à condition que: lorsque R1 représente un oxohexyle et R2 un hydrogène, alors R3 ne peut pas être un pentyle; lorsque R1 représente un oxoheptyle et R2 un hydrogène, alors R3 ne peut pas être un hexyle; lorsque R1 représente un oxononyle et R2 un hydrogène, alors R3 ne peut pas être un octyle; lorsque R1 un oxodécyle et R2 un hydrogène, alors R3 ne peut pas être un nonyle; et lorsque R1 représente un oxodécyle et R2 un hydrogène, alors R3 nepeut pas être un undécyle. Ces composés constituent des composés inhibiteurs puissants et spécifiques pour les enzymes du type élastase, tel que notamment l'élastase leucocytaire humaine, (HLE) et on peut prévoir que ces composés ont une utilité dans le traitement des maladies dans lesquelles sont impliquées des enzymes du type élastase, tel que l'arthrite, la croissance des tumeurs et les emphysèmes. La production et le procédé d'utilisation de ces composés ainsi que des compositions pharmaceutiques les contenant sont également décrits.
