  Synthesis and antimicrobial evaluation of amide derivatives of benzodifuran-2-carboxylic acid

  摘要：

  We have synthesized various amide derivatives of benzodifuran-2-carboxylic acid from resorcinol. Reaction of 7-hydroxy-4-methylcoumarin with chloroacetone in anhydrous K2CO3 and dry acetone gave ether derivative of 7-hydroxy-4-methylcoumarin 3 which on reaction with N-bromosuccinimide in chloroform gave corresponding 3-bromo derivative 4. Cyclization of bromo derivative in 10% ethanolic KOH gave benzodifuran-2-carboxylic acid 5. This acid was converted into acid chloride using oxalyl chloride and then substituted with different amines in presence of base, triethylamine to give amide derivatives of benzodifuran-2-carboxylic acid 6. All compounds were screened for antimicrobial activity against two Gram positive bacteria Staphylococus aureus and Bacillus subtilis, two Gram negative bacteria E. coli and P. aeruginosa and one fungus Candida albicans.

  Improved synthesis, X-ray structure, and antifungal activity of a sugar-psoralen conjugate: 4,4′-Dimethylxanthotoxol 2,3,4,6-tetra-O-Acetyl-β-D-glucoside

  摘要：

  An improved synthesis for 4,4 '-dimethylxanthotoxol 2,3,4,6-tetra-O-acetyl-beta-D-glucoside (1) starting from resorcinol was developed. Crystallographic analysis of glucoside 1 indicated that the dihedral angles between the mean planes of the tricyclic ring system of adjacent molecules was 54.820(22)degrees probably due to the steric hindrance caused by the bulky O-glucoside moiety, which prevents the molecules from packing via pi center dot center dot center dot pi stacking between the tricyclic cores. The antifungal screening data revealed that glucoside 1 had higher inhibition than its parent compound 4,4 '-dimethylxanthotoxol and azoxystrobin against Rhizoctonia solani, Pyricularia grisea, and Alternaria alternate Japanese pear pathotype, with the inhibitory rates of 75.4, 65.7 and 70.1%, respectively, at the 50 mu g/mL concentration.[GRAPHICS].

  A series of 7‐(2‐oxoalkoxy)coumarins have been synthesized by conjugating substituted 7‐hydroxycoumarins with different chloroketones. The anti‐inflammatory properties of 7‐(2‐oxoalkoxy)coumarins were studied in LPS‐induced inflammatory response in J774 macrophages. Western blot was used to determine the expression of iNOS and COX‐2, NO was determined by measuring its metabolite nitrite by Griess reaction

  通过将取代的7-羟基香豆素与不同的氯酮缀合，可以合成一系列7-（2-氧代烷氧基）香豆素。在L774诱导的J774巨噬细胞的炎症反应中研究了7-（2-氧代烷氧基）香豆素的抗炎特性。用Western印迹法测定iNOS和COX-2的表达，通过Griess反应测定其代谢产物亚硝酸盐测定NO，通过ELISA测定IL-6。在100μM的浓度下，有17种被研究的化合物抑制NO和IL-6的产生超过50％。最佳抑制剂的IC 50值对于化合物12为21μM/ 24μM（NO / IL-6），对于化合物20为30μM/ 10μM（NO / IL-6）。主要结果是，被7-（2-氧代烷氧基）取代可改善大多数研究的7-羟基香豆素的抗炎特性。

  New amino psoralen derivatives have been synthesized via bromination. Bromination of 3,5‐substituted psoralens has been studied. The second position of the furan ring is more susceptible to bromination than the α‐position of the chromen‐2‐one ring in psoralens. Hence, the target psoralenamines were synthesized starting with 3‐bromo‐7‐hydroxy‐4‐methyl‐chromen‐2‐one, which was condensed with different

  通过溴化合成了新的氨基补骨脂素衍生物。已经研究了3,5-取代的补骨脂素的溴化。呋喃环的第二个位置比补骨脂素中的chromen-2-one环的α-位置更容易被溴化。因此，目标补骨脂胺是从3-溴-7-羟基-4-甲基-铬烯-2-酮开始合成的，然后与不同的α-卤代酮缩合，然后在乙醇氢氧化钾中环化，得到所需的6-溴补骨脂素。 ，最终被转化为补骨脂素。J.杂环化​​学。（2010）。

  novel. The derivatives displayed anti‐inflammatory activity by suppressing iNOS and IL‐6 expression, but their mechanism of action seemed to be dependent on the substitution. Compound 6 with propyl side chain inhibited NF‐κB mediated transcription, while compound 10 with a phenyl substituent down‐regulated iNOS expression in a posttranscriptional manner. The results introduce psoralen derivatives as promising

  作为香豆素研究的一个连续过程，合成了12种补骨脂素并评估了它们的抗炎活性。补骨脂素分三步制备：首先，通过von Pechmann缩合反应合成7-羟基香豆素，然后转化为7-（2-氧代丙氧基）香豆素。在最后一步中，将稠合的呋喃环引入分子内的环形成反应中。根据SciFinder搜索，发现12种合成的补骨脂素衍生物中的两种（化合物9和12）是新颖的。这些衍生物通过抑制iNOS和IL-6的表达而具有抗炎活性，但其作用机理似乎取决于取代。化合物6带有丙基侧链的化合物抑制NF-κB介导的转录，而带有苯基取代基的化合物10以转录后方式下调iNOS的表达。结果介绍了补骨脂素衍生物作为有希望的抗炎化合物，有可能治疗涉及iNOS和/或IL-6介导的不良反应的疾病。

  In a search for new inhibitors of platelet aggregation, certain coumarin-bearing α-methylene-γ-butyrolactones were synthesized and evaluated for inhibitory activity against thrombin (Thr)-, arachidonic acid (AA)-, collagen (Col)-, and platelet-activating factor (PAF)-induced aggregation in washed rabbit platelets. These compounds were efficiently synthesized from commercially available 7-hydroxycoumarin or its derivative. Among them, 7-[(2, 3, 4, 5-tetrahydro-4-methylene-5-oxo-2-phenyl-2-furanyl)methoxy]-2H-1-benzopyran-2-one (3d) showed the most potent inhibition of AA- and PAF- induced aggregation, with IC50 values of 3.65 and 16.36μM respectively.
