  A Quantitative Structure−Activity Relationship Study of Herbicidal Analogues of α-Hydroxy-Substituted 3-Benzylidenepyrrolidene-2,4-diones

  摘要：

  A series of pyrrolidine-2,4-dione and piperidine-2,4-dione derivatives were prepared and evaluated for their herbicidal activities where some of these compounds exhibited good bioactivity against Echinochloa crus-galli in comparison with sulcotrione. Quantitative structure- activity relationship studies were performed on these compounds using physicochemical parameters ( hydrophobic, electronic, and Taft) as independent parameters and herbicidal activity as a dependent parameter, where herbicidal activity correlated best (r > 0.8) with hydrophobic (pi degrees + pi(p)), steric (Es), STERIMOL (B4), indicator (H-M), van der Waals volume (V), and electronic parameter (sigma(m) + sigma(p)) in this set of molecules; the optimum van der Waals volume for R-2 is about 41.8 A(3); when B4 is equal to 3, the target molecule possessed the lowest herbicidal activity.

  鉴定 CH2 连接的喹诺酮-氨基嘧啶杂合体作为有效的抗 MRSA 药物：耐药潜力低且与氟喹诺酮抗生素缺乏交叉耐药性

  摘要：

  我们之前获得的一种抗菌剂 的结构优化导致发现了一类新的 CH 连接的喹诺酮-氨基嘧啶杂合体，具有有效的抗 MRSA 活性。令人惊讶的是，在喹诺酮核上缺少 C-6 氟原子的杂合体表现出与相应的 6-氟对应物相同甚至更强的抗 MRSA 活性，尽管已建立的构效关系 (SAR) 表明 6-氟原子取代基增强了传统氟喹诺酮类抗生素的抗菌活性。此外，这些新的杂合体尽管在结构上与传统氟喹诺酮类药物相关，但与氟喹诺酮类药物不存在交叉耐药性。最活跃的化合物，对氟喹诺酮敏感菌株 USA500 和耐药 MRSA 分离株 Mu50 均表现出优异的活性，MIC 值为 0.39 μg/mL。进一步的耐药性发展研究表明 MRSA 不太可能获得针对 的耐药性。此外，还表现出良好的半衰期和安全性。这些发现为进一步进化具有高耐药性的喹诺酮类抗生素提供了理论依据。

  relationships of a novel series of N-phenyl-substituted pyrrole, 1,2-pyrazole and 1,2,3-triazole acid analogs as PPAR ligands are outlined. The triazole acid analogs 3f and 4f were identified as potent dual PPARα/γ agonists both in binding and functional assays in vitro. The 3-oxybenzyl triazole acetic acid analog 3f showed excellent glucose and triglyceride lowering in diabetic db/db mice.

  Novel 6-substituted-4-cycloalkyloxy-pyridin-2(1H)-ones were synthesized as non-nucleoside reverse transcriptase inhibitors (NNRTIs), and their biological activity was evaluated. Most of the compounds, especially 26 and 22, bearing a 3-isopropyl and 3-iodine group, respectively, exhibited highly potent activity against wild-type HIV-1 strains and those resistant to reverse transcriptase inhibitors (RTIs)

• New synthetic analogues of N-acyl homoserine lactones as agonists or antagonists of transcriptional regulators involved in bacterial quorum sensing

  A series of 22 novel synthetic N-acyl-homoserine lactone analogues has been evaluated for both their inducing activity and their ability to competitively inhibit the action of 3-oxo-hexanol-L-homoserine lactone. the natural inducer of bioluminescence in the bacterium Vibrio fischeri. In the newly synthesized analogues, the extremity of the acyl chain was modified by introducing ramified alkyl, cycloalkyl or aryl substituents at the C-4 position. Most of the analogues bearing either acyclic or cyclic alkyl substituents showed inducing activity. In contrast, the phenyl substituted analogues displayed significant antagonist activity. We hypothesized that the antagonist activity of the phenyl compounds may result from the interaction between the aryl group and aromatic amino acids of the Lux R receptor, preventing it from adopting the active dimeric form.
