1小柴胡汤对体外培养人肝癌细胞株HepG2增殖的影响显示文摘目的探讨小柴胡汤45%乙醇提取物对体外培养人肝癌细胞株HepG2增殖的影响及其可能的机理。方法采用ATP-Lite法测定不同浓度小柴胡汤对体外培养的HepG2增殖的作用,同时利用氧自由基清除能(ORAC)法测定样品的抗氧化活性;以LPS刺激小鼠巨噬细胞RAW264.7产生一氧化氮(NO),Griess法测定NO的终产物亚硝酸盐的含量,观察样品对NO生成的影响。结果小柴胡汤在62.5~500mg/L浓度范围内可以显著抑制HepG2增殖,抑制作用呈剂量相关性,计算半数抑制浓度(IC50)为(90.7±23.7)mg/L。小柴胡汤提取物具有一定的抗氧化活性,其抗氧化能力为阳性对照维生素C的1.3倍。小柴胡汤在3.125~50mg/L浓度范围内均可以显著抑制NO的生成(P<0.05,P<0.01)。结论小柴胡汤具有体外抑制人肝癌细胞株HepG2增殖的作用,其抑制作用可能与其抗氧化活性及抑制NO生成有关。廖晖 David J de Vries Linda K Banbury David N Leach 2010中国中医药信息杂志2010,17,11:7

3向在人的察觉到钙的受体的 allosteric 药的结构的理解显示文摘allosterically 指向人的察觉到钙的受体(CaSR ) 的药有实质的治疗学的潜力,但是当前被限制。给 CaSR 的高分辨率的结构的缺席,我们把 mutagenesis 与一条新奇分析途径并且开发 “ 的分子的建模相结合; enriched”为在 Ca 2+ 在 CaSRs 7 transmembrane (7TM ) 以内的 o 和 allosteric 调节的人领域。修改多重有约束力的地点以适应在结构上的一个扩大的洞多样的 ligands 被识别。Phenylalkylamines 绑在与通常认为的 Ca 2+ o -binding 地点并且向一个细胞外的门厅延长。相反,在结构上和 pharmacologically 不同的 AC-265347 在 7TM 领域以内更深绑。而且,不同氨基酸网络被发现调停由不同调节的人的 cooperativity。这些调查结果可以与不同、潜在地偏导小径的药理学效果便于 allosteric 调节的人的合理设计。Katie Leach Karen J Gregory Irina Kufareva Elham Khajehali Anna E Cook Ruben Abagyan Arthur D Conigrave Patrick M Sexton Arthur Christopoulos 2016Cell Research2016,26,5:2
