and annexin V/propidium iodide staining. The effect of the three least toxic amiodarone analogs on the human ether-a-go-go-related gene (hERG) channel was compared with amiodarone. Amiodarone, B2-O-acetate, and B2-O-Et-N-dipropyl (each 10 microM) significantly reduced the hERG tail current amplitude, whereas 10 microM B2-O-Et displayed no detectable effect on hERG outward potassium currents. In conclusion
这项工作的目的是比较胺碘酮(2-正丁基-3- [3,5二碘-4--4-二乙基氨基乙氧基苯甲酰基]-苯并呋喃; B2-O-Et-N-二乙基)的肝细胞毒性和药理活性。胺碘酮衍生物。研究了三种胺碘酮代谢产物,即单-N-去乙基胺碘酮(B2-O-Et-NH-乙基),二-N-去乙基胺碘酮(B2-O-Et-NH(2))和(2-丁基-苯并呋喃带有乙醇侧链的(-3-基)-(4-羟基-3,5-二碘苯基)-甲酮(B2)[(2-丁基苯并呋喃-3-基)-[4-(2-羟基乙氧基)-3,5 -二碘苯基]-甲酮; B2-O-Et-OH]。另外,研究了五个胺碘酮类似物,即N-二甲基胺碘酮(B2-O-Et-N-二甲基),N-二丙基胺碘酮(B2-O-Et-N-二丙基),B2-O-携带乙酸酯侧链[[4-(2-丁基-苯并呋喃-3-羰基)-2,6-二碘代苯基]-乙酸; B2-O-乙酸盐],带有丙酰胺侧链的B2-O-Et(B2-O-E-丙酰胺)和带有乙基侧链的B2-O
