    • The present invention relates generally to the detection and measurement of transmembrane potentials using an N,N,N′-trialkyl thiobarbituric acid-derived polymethine oxonol (shown below). In particular, the present invention is directed to compositions and optical methods for determining transmembrane potentials across the plasma membrane of biological cells using a slightly hydrophobic N,N,N′-trialkyl thiobarbituric acid-derived polymethine oxonols. The method comprises a slightly hydrophobic N,N,N′-trialkyl thiobarbituric acid-derived polymethine oxonol anion capable of redistributing from a first face of the membrane to a second face of the membrane in response to changes in the potential of the membrane. In one aspect the method is used to identify compounds which modulate membrane potentials in biological membranes. wherein R1, R2, and R3 are independently selected from the group consisting of hydrogen, alkyl, haloalkyl and heteroalkyl; n is an integer from 1 to 3; Z is Na, K, ammonium or other biologically acceptable salt.
    • 本发明一般涉及使用N,N,N'-三烷基硫代巴比妥酸衍生的聚甲基氧杂多酚(如下所示)检测和测量跨膜电位。 特别地,本发明涉及使用稍微疏水的N,N,N'-三烷基硫代巴比妥酸衍生的聚甲基氧杂多糖测定生物细胞质膜跨膜电位的组合物和光学方法。 该方法包括一种稍微疏水的N,N,N'-三烷基硫代巴比妥酸衍生的聚甲基氧杂氮杂阴离子,其能够响应膜的电位变化而从膜的第一面再分配到膜的第二面。 在一个方面,该方法用于鉴定调节生物膜中膜电位的化合物。 其中R1,R2和R3独立地选自氢,烷基,卤代烷基和杂烷基; n为1〜3的整数, Z是Na,K,铵或其他生物可接受的盐。
