1巨峰和无核早红葡萄在越南谅山试种观察显示文摘[目的]观察巨峰、无核早红葡萄在越南谅山省的引种表现,为其在越南推广种植提供参考依据.[方法]2009年春从中国南宁引入巨峰、无核早红两个鲜食葡萄品种在越南谅山省试种,调查其枝蔓生长量、物候期、果实性状、产量等相关指标.[结果]至第1年抚育冬季,巨峰葡萄枝蔓总长234.5 cm,上架茎粗0.84 cm;无核早红葡萄枝蔓总长294.1 cm,上架茎粗0.86 cm.在物候期方面,巨峰葡萄从萌芽至果实成熟需141~151 d,表现中熟;无核早红从萌芽至果实成熟需142~151 d,未表现其应有的早熟特性.在果实性状方面,巨峰葡萄2010~2012年3年平均单果重8.9 g,种子数1.04粒,可溶性固形物(TSS)含量17.5%;无核早红葡萄2010~2012年3年平均单果重6.8 g,TSS含量13.9%.在产量方面,巨峰葡萄2010~2012年产量分别为13.69、17.50和16.24 t/ha;无核早红葡萄2010~2012年产量分别为10.81、16.02和20.92t/ha.[结论]巨峰葡萄在越南谅山省种植表现丰产稳产优质,具有较好的适栽性,可大面积推广种植;无核早红葡萄表现丰产稳产,但表现低糖低酸,极易裂果,着色困难,不宜在越南大面积发展.黄江流 PHAM Thi Thang 罗瑞鸿 NGUYN Thi Hà 吕荣华 LUONG Dǎng Ning CHU Vǎn DUòng NGUYN Manh Tòng 彭宏祥 Ly Ming Nguyet LU'O'NG i Thuy CHU Xun Tien VI Vǎn Dúc NGUYN Duy Dng Ly Dúc Khiêm 熊俏 2014南方农业学报2014,45,7:5

4Structure-activity relationship of pyrazol-4-ylpyridine derivatives and identification of a radiofluorinated probe for imaging the muscarinic acetylcholine receptor M4显示文摘There is an accumulating body of evidence implicating the muscarinic acetylcholine receptor4(M4)in schizophrenia and dementia with Lewy bodies,however,a clinically validated M4positron emission tomography(PET)radioligand is currently lacking.As such,the aim of this study was to develop a suitable M4PET ligand that allows the non-invasive visualization of M4in the brain.Structure-activity relationship studies of pyrazol-4-yl-pyridine derivates led to the discovery of target compound 12—a subtype-selective positive allosteric modulator(PAM).The radiofluorinated analogue,[18F]12,was synthesized in 28±10%radiochemical yield,>37 GBq/μmol and an excellent radiochemical purity>99%.Initial in vitro autoradiograms on rodent brain sections were performed in the absence of carbachol and showed moderate specificity as well as a low selectivity of[18F]12 for the M4-rich striatum.However,in the presence of carbachol,a significant increase in tracer binding was observed in the rat striatum,which was reduced by>60%under blocking conditions,thus indicating that orthosteric ligand interaction is required for efficient binding o f[18F]12 to the allosteric site.Remarkably,however,the presence of carbachol was not required for high specific binding in the non-human primate(NHP)and human striatum,and did not further improve the specificity and selectivity of[18F]12 in higher species.These results pointed towards significant species-differences and paved the way for a preliminary PET study in NHP,where peak brain uptake of[18F]12 was found in the putamen and temporal cortex.In conclusion,we report on the identification and preclinical development of the first radiofluorinated M4PET radioligand with promising attributes.The availability of a clinically validated M4PET radioligand harbors potential to facilitate drug development and provide a useful diagnostic tool for non-invasive imaging.Ahmed Haider Xiaoyun Deng Olivia Mastromihalis Stefanie K.Pfister Troels E.Jeppesen Zhiwei Xiao Vi Pham Shaofa Sun Jian Rong Chunyu Zhao Jiahui Chen Yinlong Li Theresa R.Connors April T.Davenport James B.Daunais Vahid Hosseini Wenqing Ran Arthur Christopoulos Lu Wang Celine Valant Steven H.Liang 2023Acta Pharmaceutica Sinica B2023,13,1:0
