Inclusion of the allylic functions presented an enhanced potential area of biotransformation, and thus alcuronium is observed to have a much shorter duration of neuromuscular blocking action than its parent C-toxiferine I.
Adding allylic groups to the molecule increased its ability to be transformed by biological processes, resulting in alcuronium having a quicker breakdown and shorter effect on muscle function compared to its precursor, C-toxiferine I.
