The invention provides neuromuscular blockade agents of the non-depolarizing type with few if any circulatory effects. Compounds of the invention include bis(isoquinolylalkanol) diesters of fumaric, maleic, succinic, and acetylenedicarboxylic acids; compositions suitable for parenteral administration of these compounds as a surgical adjunct to anesthesia, and methods of preparation of the compounds. Compounds of the invention can produce neuromuscular blockade of short or intermediate duration, which for various compounds can be reversed by administration of a thiol compound such as L-cysteine, D-cysteine or glutathione. For various compounds of the invention, the neuromuscular blockade effect can be reversed quickly, efficiently, and without notable side-effects.
                            本发明提供了一种非去极化型肌肉松弛剂,具有很少或没有循环系统影响。本发明的化合物包括
富马酸、
马来酸、
琥珀酸和
乙炔二
羧酸的双(
异喹啉基)烷醇二酯;适用于这些化合物的静脉注射制剂,作为麻醉手术辅助剂;以及这些化合物的制备方法。本发明的化合物可以产生短或中等持续时间的神经肌肉阻滞,对于各种化合物可以通过给予巯基化合物(如
