1R-cis,1'R-cis isomer of a 2',2'-(3,11-dioxo-4,10-dioxatridecylene)-bis(1,2,3,4-tetrahydro-6, 7-dimethoxy-2-methyl-1-veratrylisoquinolium) said, substantially free from other geometrical and optical isomers thereof. The 1R-cis,1'R-cis isomer has been found to have an advantageous combination of pharmacological properties, notably greater neuromuscular blocking potency, weaker histamine-releasing potency, and at equivalent levels of neuromuscular blockade, fewer potential adverse effects on the autonomic nervous system (sympathetic and parasympathetic blockage), in comparison with the known mixture of geometrical and optical isomers.
一种2',2'-(3,11-二氧化-4,10-二氧杂十二烷基)-双(1,2,3,4-四氢-6,7-二甲氧基-2-甲基-1-维拉特利异喹啉)的1R-cis,1'R-cis同分异构体,基本上不含其他几何和光学同分异构体。已发现1R-cis,1'R-cis同分异构体具有有利的药理特性,特别是更强的神经肌肉阻滞效力,较弱的组胺释放效力,并且在相同水平的神经肌肉阻滞下,对自主神经系统(交感神经和副交感神经阻滞)的潜在不良影响较少,与已知的几何和光学同分异构体混合物相比。
