  摘要：

  In the present communication, a series based on 1-[2-(6-nitro-4-oxo-2-phenyl-4H-quinazolin-3-yl)-ethyl]-3- phenyl-urea have been synthesized by an efficient synthetic protocol. The synthesized compounds were characterized by IR, H-1 NMR, C-13 NMR spectroscopy, ESI Mass spectrometry, and elemental analysis. The antibacterial and antifungal activity of the compounds were studied against selected strains (Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Bacillus subtilis ATCC 11774, and Candida albicans ATCC 66027) by using Kirby Bauer disk diffusion technique and broth dilution technique. All the synthesized compounds showed good antifungal potency against strain C. albicans.

  Abstract A series of synthetically interesting 2-arylbenzoxazinones was prepared from 2-arylindoles by an efficient oxidative reaction mediated by (diacetoxyiodo)benzene [PhI(OAc)2] and assisted by water. PhI(OAc)2 was used as the sole oxidant and water was a crucial additive. Our preliminary mechanistic investigations suggest that a water-involved, iodine(III)-promoted sequential oxidation of 2-arylindoles

  An efficient protocol for the introduction of acetoxy and hydroxy functionalities on unactivated aryl sp2 carbons of oxobenzoxazine derivatives via an ortho-C–H activation reaction using a palladium catalyst has been developed for the first time. Interestingly, this intermolecular C–H functionalization reaction takes place in a facile and simple manner with high chemo- and site selectivity.

  Three series of sulfonamides incorporating long, bulky tails were obtained by applying synthetic strategies in which substituted anthranilic acids, quinazolines and aromatic sulfonamides have been used as starting materials. They incorporate long, bulky diamide-, 4-oxoquinazoline-3-yl-or quinazoline-4-yl moieties in their molecules, and were investigated for the inhibition of four physiologically relevant carbonic anhydrase (CA, EC 4.2.1.1) isoforms, the cytosolic human (h) hCA I and II, as well as the transmembrane hCA IX and XII. Most of the new sulfonamides showed excellent inhibitory effects against the four isoforms, with K(I)s of 7.6-322 nM against hCA I, of 0.06-85.4 nM against hCA II; of 6.7-152 nM against hCA IX and of 0.49-237 nM against hCA XII; respectively. However no relevant isoform-selective behavior has been observed for any of them, although hCA II and XII, isoforms involved in glaucoma-genesis were the most inhibited ones. The structure-activity relationship for inhibiting the four CAs with these derivatives is discussed in detail. (c) 2015 Elsevier Ltd. All rights reserved.
