    由乙烯基腈温和合成硫醇腈及其环化反应†
    摘要:
    硫代乙酸A的硫醇-烯加成法广泛用于由乙烯基前体合成硫醇,但到目前为止,尚未在非共轭乙烯基腈上进行。使用乙烯基腈时,面临的挑战是选择性进行硫醇-烯加成,同时避免将A亲核加成至腈基。我们发现,只要存在化学引发剂量的A,乙烯基腈在光引发剂的存在下就能选择性地诱导UV诱导的硫醇-烯加成反应。乙烯基基团上可以使用乙烯基,并且使用空间上不受阻碍的乙烯基。相反,当使用位阻乙烯基时,腈的亲核加成是有利的。所制备的硫醇腈在碱性和酸性条件下以及在硅胶存在下均可轻松进行环化反应。这说明了腈对硫醇添加的高反应性。1,2-乙二硫醇B是A的替代试剂,因为它允许在温和的和非酸性的反应条件下将乙烯基腈直接转化为硫醇。

Furthermore, Dox-SS-[C(WR)4K] showed significantly higher cytotoxic activity in HEK-293, HT-1080, and SKOV-3 cells when compared with Dox after 72 h incubation.

    curcumin-doxorubicin conjugated cyclic peptide scaffold to improve the solubility of curcumin and create a conjugate containing two anticancer agents. A solid-phase Fmoc/tBu solid phase methodology was used to synthesize a cell-penetrating nuclear targeting peptide with free thiol and amine groups, which was coupled with the activated doxorubicin (Dox) and curcumin, affording Dox-peptide-curcumin conjugate (DPCC)
    姜黄素的疏水性为其在抗癌治疗中的应用创造了障碍。在这里,我们合成了姜黄素-阿霉素偶联的环状肽支架,以提高姜黄素的溶解度并创建包含两种抗癌剂的偶联物。使用固相Fmoc / tBu固相方法合成具有游离巯基和胺基的穿透细胞的核靶向肽,然后将其与活化的阿霉素(Dox)和姜黄素偶联,得到Dox-肽-姜黄素共轭物(DPCC) )(10)。在人白血病癌细胞(CCRF-CEM),人卵巢癌细胞(SKOV-3)和正常肾细胞系(LLCPK)中评估了缀合物的抗增殖活性。环肽-阿霉素结合物(7)和DPCC(10)孵育72小时后,没有抑制正常肾脏LLCPK细胞的增殖,但对CCRF-CEM(分别为73%和41%)和SKOV-3(分别为55%和30%)细胞具有细胞毒性,而Dox具有细胞毒性(60-79%)在所有三种细胞系中都处于相似的条件下,表明这些化合物对癌细胞具有选择性。
  • Preparation of a TK/GCV administration system mediated by transferrin modified pro-cationic liposomes
    作者:Zhong, Zhi-Rong、Zhang, Zhi-Rong、Deng, Yong、Liu, Ji、Song, Qing-Guo、Liu, Jie、He, Qin

    Transferrin modified pro-cationic liposomes were prepared and used to investigate the effect of targeting therapeutic genes to human hepatoma carcinoma cells in vitro. The main lipid CHETA, cholest-5-en-3β-yl[2-[[4-[(carboxymethyl)dithio]-1-iminobutyl]amino]ethyl] carbamate (C36H61N3O4S2), was synthesized and used to prepare pro-cationic liposomes. The thymidine kinase (TK) gene loaded pro-cationic liposomes were prepared by first mixing the plasmid DNA and protamine together, and then incubating the resulted polyplexes with blank pro-cationic liposomes preformed by the thin film dispersion-sonication method. Transferrin (Tf) was adsorbed on the surface of pro-cationic liposomes via electrostatic interactions to form transferrin modified pro-cationic liposomes. Cellular association was measured by fluorimetry at excitation and emission wavelengths of 490 and 520 nm, respectively. The viability of TK gene infected cells following administration of ganciclovir (GCV) was investigated by MTT assay. The transferrin modified TK gene pro-cationic liposomes had a mean diameter of 240 ± 12 nm and zeta potential of –24.10 ± 2.5 mV (n = 3). The transmission electron microscopy image indicated that most of the liposomes were relatively regular and spherical with a condensed core inside. Cell-associated fluorescence of Tf-liposomes and unmodified liposomes (without transferrin) was 7.8 × 106, and 3.2 × 106 per milligram protein, respectively. Compared to LipofectamineTM 2000 (Invitrogen, USA) the pro-cationic liposomes and transferrin modified pro-cationic liposomes had less cytotoxicity to cells. The transduced TK gene HepG2 cells were more sensitive to GCV than the un-transduced TK gene ones and the human normal Chang liver cells were not affected by the TK/GCV system mediated by procationic liposomes.
    转铁蛋白修饰的前阳离子脂质体被制备并用于研究靶向治疗基因对人肝肿瘤细胞的体外效果。主要脂质CHETA、胆固醇-5-烯-3β-基[2-[[4-[(羧甲基)二硫]-1-亚氨基丁基]氨基]乙基]氨基甲酸酯(C36H61N3O4S2)被合成并用于制备前阳离子脂质体。负载胸苷激酶(TK)基因的前阳离子脂质体是通过将质粒DNA与鱼精蛋白混合后,孵育得到的聚复合物与通过薄膜分散-超声法预先形成的空白前阳离子脂质体。转铁蛋白(Tf)通过静电相互作用被吸附在前阳离子脂质体的表面,从而形成转铁蛋白修饰的前阳离子脂质体。细胞结合量通过在490和520 nm的激发和发射波长下进行荧光测定来测量。通过MTT法研究了在施用更昔洛韦(GCV)后,TK基因感染细胞的存活率。转铁蛋白修饰的TK基因前阳离子脂质体的平均直径为240 ± 12 nm,zeta电位为–24.10 ± 2.5 mV(n = 3)。透射电子显微镜图像显示,大多数脂质体相对规则且呈球形,内部有致密的核心。Tf-脂质体和未修饰脂质体(未含转铁蛋白)的细胞结合荧光分别为7.8 × 106和3.2 × 106每毫克蛋白。与LipofectamineTM 2000(Invitrogen, USA)相比,前阳离子脂质体和转铁蛋白修饰的前阳离子脂质体对细胞的细胞毒性较低。转导的TK基因HepG2细胞对GCV的敏感性高于未转导的TK基因细胞,而人正常Chang肝细胞则未受到前阳离子脂质体介导的TK/GCV系统的影响。
