    Cytotoxic triterpenoid–safirinium conjugates target the endoplasmic reticulum
    摘要:
    Safirinium P and Q fluorescence labels were synthesized and conjugated with spacered triterpenoic acids to access hybrid structures. While the parent safirinium compounds were not cytotoxic at all, many triterpenoid safirinium P and Q conjugates showed moderate cytotoxicity. An exception, however, was safirinium P derived compound 30 holding low EC50 = 5.4 μM (for A375 cells) to EC50 = 7.5 μM (for FaDu cells) as well as EC50 = 6.6 μM for non-malignant fibroblasts NIH 3T3. Fluorescence imaging showed that the safirinium core structures cannot enter the cells (not even after a prolonged incubation time of 24 h), while the conjugates (as exemplified for 30) are accumulating in the endoplasmic reticulum but not in the mitochondria. The development of safirinium-hybrids targeting the endoplasmic reticulum can be regarded as a promising strategy in the development of cytotoxic agents.

    properties and very good water solubility allowed for the development of a simple method for the determination of exemplary amino acids by means of micellar electrokinetic chromatography. Moreover, a new class of fluorescent peptide building blocks comprising a spiro-conjugated Safirinium-proline system was obtained. Due to the presence of a permanent positive charge, Safirinium-amino acid dervatives are
    摘要 通过与 Safirinium 染料的 N-羟基琥珀酰亚胺酯的偶联反应衍生出蛋白氨基酸。所得化合物通过 1H 和 13C NMR、IR 和 ESI-MS 光谱技术进行了充分表征。进行了元素分析以及示例性化合物的晶体结构分析。已系统地研究了所得衍生物的吸收和荧光性质。光学特性和非常好的水溶性使得开发出一种通过胶束电动色谱法测定示例性氨基酸的简单方法成为可能。此外,获得了一类新的荧光肽构建块,包括螺偶联的 Safirinium-脯氨酸系统。由于存在永久性正电荷,Safirinium-氨基酸衍生物是 MS 蛋白质组学分析中信号增强剂的潜在候选物。证明了所检查的电离标签在信号增强和肽测序中的适用性。所得结果为开发利用吸收、荧光和质谱法检测痕量氨基酸、肽和蛋白质的新方法提供了实验基础。

    A series of novel fluoroquinolone-Safirinium dye hybrids was synthesized by means of tandem Mannich-electrophilic amination reactions from profluorophoric isoxazolones and antibiotics bearing a secondary amino group at position 7 of the quinoline ring. The obtained fluorescent spiro fused conjugates incorporating quaternary nitrogen atoms were characterized by 1H NMR, IR, MS, and elemental analysis
