  Structural Requirements for Factor Xa Inhibition by 3-Oxybenzamides with Neutral P1 Substituents:  Combining X-ray Crystallography, 3D-QSAR, and Tailored Scoring Functions

  摘要：

  The design, synthesis, and structure-activity relationship of 3-oxybenzamides as potent inhibitors of the coagulation protease factor Xa are described on the basis of X-ray structures, privileged structure motifs, and SAR information. A total of six X-ray structures of fXa/inhibitor complexes led us to identify the major protein-ligand interactions. The binding mode is characterized by a lipophilic dichlorophenyl substituent interacting with Tyr228 in the protease S1 pocket, while polar parts are accommodated in S4. This alignment in combination with docking allowed derivation of 3D-QSAR models and tailored scoring functions to rationalize biological affinity and provide guidelines for optimization. The resulting models showed good correlation coefficients and predictions of external test sets. Furthermore, they correspond to binding site topologies in terms of steric, electrostatic, and hydrophobic complementarity. Two approaches to derive tailored scoring functions combining binding site and ligand information led to predictive models with acceptable predictions of the external set. Good correlations to experimental affinities were obtained for both AFMoC (adaptation of fields for molecular comparison) and the novel TScore function. The SAR information from 3D-QSAR and tailored scoring functions agrees with all experimental data and provides guidelines and reasonable activity estimations for novel fXa inhibitors.

  New chemiluminescent compounds, stable in aqueous buffers, for use in biological assaying include acridanebased compounds and (1,2)-dioxetanes. Among the new acridanebased compounds are water-soluble acridanes, enhancer coupled acridanes, bis and trisacridanes as well as acridane-(1,2)-dioxetanes. Among the new (1,2)-dioxetanes are electron deficient group-containing dioxetanes and tethered bis-1,2-dioxetanes. The (1,2)-dioxetanes are useful as substrates for various enzymes. The acridanes can be admixed with an oxidizing agent. An aqueous buffer and, optionally, a stabilizer to form a substrate or reagent formulation useful for assaying, inter alia, HRP.

• Isolation of Bright Blue Fluorescent Substances from Sonochemical Hydroxylation of Methyl<i>p</i>-Cyanobenzoate

  DOI：10.1246/cl.1999.197

  日期：1999.3

  Sonochemical hydroxylation of methyl p-cyanobenzoate (1a) in water gave a bright blue fluorescence, which are mainly ascribed to three new fluorescent compounds, 3-hydroxy, 2,3-and 2,5-dihydroxy derivatives of 1a. Other benzenes substituted with electron-withdrawing groups also gave similar fluorescence from their hydroxylated derivatives. Among the fluorescence substances, methyl 2,5-dihydroxybenzoate was supposed to be applicable for a fluorescent chemosensor.

  对氰基苯甲酸甲酯（1a）在水中发生声化学羟基化反应后发出明亮的蓝色荧光，这主要归因于 1a 的 3-羟基、2,3 和 2,5- 二羟基衍生物这三种新的荧光化合物。其他被抽电子基团取代的苯也能从其羟基衍生物中发出类似的荧光。在这些荧光物质中，2,5-二羟基苯甲酸甲酯被认为适用于荧光化学传感器。
