  Investigation of the requirements for efficient and selective cytochrome P450 monooxygenase catalysis across different reactions

  摘要：

  The cytochrome P450 metalloenzyme (CYP) CYP199A4 from Rhodopseudomonas palustris HaA2 catalyzes the highly efficient oxidation of para-substituted benzoic acids. Here we determined crystal structures of CYP199A4, and the binding and turnover parameters, with different meta-substituted benzoic acids in order to establish which criteria are important for efficient catalysis. When compared to the para isomers, the meta-substituted benzoic acids were less efficiently oxidized. For example, 3-formylbenzoic acid was oxidized with lower activity than the equivalent para isomer and 3-methoxybenzoic acid did not undergo O-demethylation by CYP199A4. The structural data highlighted that the meta-substituted benzoic acids bound in the enzyme active site in a modified position with incomplete loss of the distal water ligand of the heme moiety. However, for both sets of isomers the meta- or pars-substituent pointed towards, and was in close proximity, to the heme iron. The absence of oxidation activity with 3-methoxybenzoic acid was assigned to the observation that the C-H bonds of this molecule point away from the heme iron. In contrast, in the para isomer they are in an ideal location for abstraction. These findings were confirmed by using the bulkier 3-ethoxybenzoic acid as a substrate which removed the water ligand and reoriented the meta-substituent so that the methylene hydrogens pointed towards the heme, enabling more efficient oxidation. Overall we show relatively small changes in substrate structure and position in the active site can have a dramatic effect on the activity.

  An attempt was made to synthesize a series of non-cytotoxic low molecular weight compounds of varying substitutions and functionalities having pharmacophore activity like carbonyl compounds, carboxylic acid and bioisosteres like tetrazole and phenyl acrylic acid. The in vitro assay of these analogues for the inhibition of complement activity revealed significant inhibitory activity for varying substituents

  Farnesoid X receptor (FXR), a bile acid-activated nuclear receptor, regulates the metabolism of bile acid and lipids as well as maintains the stability of internal environment. FXR was considered as a therapeutic target of liver disorders, such as drug-induced liver injury, fatty liver and cholestasis. The previous reported FXR partial agonist 6 was a suitable lead compound in terms of its high potent

  法尼醇X受体（FXR）是胆汁酸激活的核受体，调节胆汁酸和脂质的代谢，并维持内部环境的稳定性。FXR被认为是肝脏疾病（如药物性肝损伤，脂肪肝和胆汁淤积症）的治疗目标。先前报道的FXR部分激动剂6就其高强度和低分子大小而言是一种合适的先导化合物，而化合物6的对接研究则显示了一个较大的未占据的疏水口袋，这可能为结构活性关系提供了更多可能性（SAR ）学习。在这项研究中，我们基于铅化合物6进行了全面的SAR和分子建模研究。所有这些努力导致鉴定出一系列新的FXR部分激动剂。在该系列中，化合物41表现出最佳的活性，并且与FXR的结合口袋有很强的相互作用。此外，化合物41通过调节FXR相关基因的表达并提高抗氧化能力，保护小鼠免受对乙酰氨基酚诱导的肝毒性。总之，这些结果表明化合物41是一种有前途的FXR部分激动剂，适合进一步研究。
• Correlation of carbon-13 substituent-induced chemical shifts:Meta- andpara-substituted methyl benzoates

  Carbon‐13 NMR spectra are reported for 69 substituted methyl benzoates in deuteriochloroform or in its mixture with dimethyl sulphoxide‐d6. The substituent‐induced chemical shifts (SCS) of the CO carbon correlate poorly with dual substituent parameters (DSP) in all possible modifications, and for meta derivatives in particular this correlation is both overpara meterized and imprecise. A much better
