Open-cage fullerenes with carbonyl functional groups on the rim of the orifice are ideal precursors for the extension of fullerene π-*** isopropylphenylaniline,which reacts selectively with the lactone moiety on the rim of the orifice,phenylenediamine reacts with the adjacent carbonyl and imino groups on a pentagon to form a quinoxaline *** dehydroxylative aromatization connects the fullerene cage π-system with the quinoxaline π-*** the NMR and UV-Vis spectra revealed an evident effect after the extension of the fullerene cage π-system.

为了解花生中磷酸烯醇式丙酮酸羧化酶(phosphoenolpyruvate carboxylase,PEPC)的功能,对二倍体祖先种野生蔓花生(Arachis duranensis)基因组数据库进行分析,发现存在9个Ad PEPC基因家族成员,这些基因的序列长度为3 584~12 956 bp,开放阅读框(ORF)长度为702~3 168 bp,分布在3、5、7、8、9、10号染色体上。蔓花生Ad PEPC家族蛋白的氨基酸序列中均含有HCO3-结合位点和PEP结合位点等保守结构域,根据序列特征可分为植物型、细菌型和序列较短的PEPC等3类,同类蛋白序列的同源性较高,基因结构中的内含子与外显子的数目也较相似。基因表达分析表明,多数成员在花或茎中的表达量较高,Ad PEPC1;2和Ad PEPC4;2在茎中的表达量最高,其他家族成员尤其是Ad PEPC2、Ad PEPC1;5和Ad PEPC1;3在花中的表达量明显高于其他组织,Ad PEPC1;5基因在叶中不表达。Ad PEPC3在根、茎、叶和花中均不表达,推测该基因为假基因。这为深入研究Ad PEPC家族基因的功能奠定了基础。
