Hydroxylation of various molecules including heterocyclic aromatics using recombinant Escherichia coli cells expressing modified biphenyl dioxygenase genes
摘要:
Various molecules, in which heterocyclic aromatics are linked with phenyl or benzyl groups, were converted to their corresponding cis-dihydrodiols by recombinant Escherichia coli cells expressing modified biphenyl dioxygenase genes. Heterocyclic aromatic compounds with substituted phenyl or aliphatic moieties were also biotransformed to the hydroxylated products by the cells. Many of the converted products were novel compounds. These compounds are potentially useful as versatile starting materials for the chemical synthesis of pharmaceuticals and biologically active organic molecules. (C) 2002 Elsevier Science Ltd.

Following the discovery of cell penetrant pyridine-4-carboxylate inhibitors of the KDM4 (JMJD2) and KDM5 (JARID1) families of histone lysine demethylases (e.g., 1), further optimization led to the identification of non-carboxylate inhibitors derived from pyrido[3,4-d]pyrimidin-4(3H)-one. A number of exemplars such as compound 41 possess interesting activity profiles in KDM4C and KDM5C biochemical and
继KDM4(JMJD2)和KDM5(JARID1)组蛋白赖氨酸脱甲基酶的家族的细胞渗透剂吡啶-4-羧酸乙酯抑制剂的发现(例如,1),导致从吡啶并[3衍生的非羧酸盐抑制剂的鉴定进一步优化,4 - d ]嘧啶-4(3 H)-一。许多示例(例如化合物41)在KDM4C和KDM5C生化和靶标特异性细胞机制分析中均具有有趣的活性。
