demonstrate that microwave irradiation can dramatically accelerate reaction rates for spatially addressable librarysynthesis on planar membrane supports. The development of a robust support/linker system, microwave-assistedsynthesis of small molecule test libraries, and methods for solid-phase scale-up on cellulose are described.

our previous work, a series of novel benzothiazepine derivatives containing pyridine moiety were successfully synthesized through chalcone 1,3-dipolar cycloaddition and determined their antiviralactivity against tobacco mosaic virus (TMV). Bioassay results indicated that most of these target compounds exhibited improved curative, protection, and inactivation activity in vivo than the commercial agent
AbstractA series of chalconederivativescontaining quinoxaline moieties were synthesized, and their antibacterial activities were evaluated. Antibacterial bioassays indicated that some of the compounds exhibited significant antibacterial activity against Xanthomonas axonopodis pv. Citri (Xac), Xanthomonas oryzae pv. oryzae (Xoo), and Ralstonia solanacearum (Rs) at the concentrations of 50 or 100 μg/cm3
摘要合成了一系列包含喹喔啉部分的查尔酮衍生物,并评估了它们的抗菌活性。抗菌生物测定结果表明,某些化合物对轴生黄单胞菌pv表现出显着的抗菌活性。柑桔(Xac),黄单胞菌(Xanthomonas oryzae)PV。浓度为50或100μg/ cm 3的稻米(Xoo)和青枯雷尔氏菌(Rsstonia solanacearum)(Rs)。(E)-3-(吡啶-2-基)-1- [4-(喹喔啉-2-基氧基)苯基] prop-2-en-1-one对Xac的50%有效浓度(EC 50)值, Xoo和Rs分别为6.72、15.17和9.29μg / cm 3,比bismerthiazol(44.31、42.46和62.36μg / cm)更好。3)。使用扫描电子显微镜(SEM)分析该化合物对Xac的抗菌作用机理。 图形概要
Design, Synthesis, and Antifungal Activity of Novel Chalcone Derivatives Containing a Piperazine Fragment
In an attempt to find the biorational pesticides, 20 novel chalcone derivatives containing a piperazine fragment were designed and synthesized. Their fungicidal activities and preliminarily action mechanism against Rhizoctonia solani were evaluated. Strikingly, the biological activity of compound D2 was obtained by optimizing the structure of the system. Subsequently, the practical value of compound
