  Design, synthesis and structure–activity relationships of 3,5-diaryl-1H-pyrazoles as inhibitors of arylamine N-acetyltransferase

  摘要：

  The synthesis and inhibitory potencies of a novel series of 3,5-diaryl-1H-pyrazoles as specific inhibitors of prokaryotic arylamine N-acetyltransferase enzymes is described. The series is based on hit compound 1 3,5-diaryl-1H-pyrazole identified from a high-throughout screen that has been carried out previously and found to inhibit the growth of Mycobacterium tuberculosis.

• Synthesis of Dibenzoylmethane Derivaives and Inhibition of Mutagenicity in Salmonella typhimurium.

  Twenty dibenzoylmethanes with methyl, methoxy, bromo, chloro, or fluoro substitution on either one or both benzene rings were synthesized and assayed for inhibition of the mutagenicity of 2-nitrofluorene in S. typhimurium TA98. 2, 2-Dimethoxy, 3, 3-dimethoxy and 3, 3, 4, 4-tetramethoxydibenzoylmethane was as active as dibenzoylmethane. None of the halogen-substituted dibenzoylmethanes were active. These results demonstrate that dibenzoylmethanes can inhibit the mutagenicity of 2-nitrofluorene, and that modifications made on the benzene rings of dibenzoylmethane cannot enhance the antimutagencity of this parent compound.

  合成了20种二苯甲酰甲烷，它们在一个或两个苯环上分别带有甲基、甲氧基、溴、氯或氟取代基，并测定了它们对S. typhimurium TA98株2-硝基芴致突变性的抑制作用。2,2-二甲氧基、3,3-二甲氧基和3,3,4,4-四甲氧基二苯甲酰甲烷与二苯甲酰甲烷同样有效。所有含卤素取代的二苯甲酰甲烷均无效。这些结果表明二苯甲酰甲烷能抑制2-硝基芴的致突变性，在二苯甲酰甲烷的苯环上作修饰并不能增强其母体化合物的抗致突变性。
• K₂CO₃-Catalyzed Synthesis of Chromones and 4-Quinolones through the Cleavage of Aromatic C–O Bonds

  Phenol-derived electrophiles are favorable substrates because phenols are naturally abundant or can be readily prepared from other aromatic compounds. However, the cleavage of aromatic C-O bonds Is a great challenge because of their high energy. K2CO3-catalyzed intramolecular cyclization of 1-(2-alkoxyphenyl)-3-akylpropane-1,3-dlone and 3-(alkylimino)-1-(2-methoxyphenyl)-2-methylpropan-1-one derivatives via the selective cleavage of aromatic C-O bonds Is reported. The corresponding chromone and 4-quinolone derivatives were obtained in reasonable yields.

  base‐mediated, green, microwave‐assisted efficient preparation of a diverse benzoxanthone library from variety of readily accessible γ‐alkynyl 1,3‐diketones is reported. The synthesis is based on tandem reactions involving intramolecular cyclization, propargyl‐allenyl isomerization, and electrocyclization in one pot. Some of the benzoxanthones are also synthesized by the one‐pot reaction of 1,3‐diketone and
