Development
Vecuronium's structure is derived from the same aminosteroid structure as pancuronium, but it is missing the methyl group on the piperidine nitrogen that is attached to the 'A' ring, making it monoquaternary, like D-tubocurarine. This means it is less potent than pancuronium as a neuromuscular blocking agent. It has the same configuration at all ten stereocentres as pancuronium, and is a single-isomer preparation.

Famous quotes containing the word development:
“America is a country that seems forever to be toddler or teenager, at those two stages of human development characterized by conflict between autonomy and security.”
—Anna Quindlen (b. 1952)
“On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.”
—Frances Ellen Watkins Harper (1825–1911)
“I can see ... only one safe rule for the historian: that he should recognize in the development of human destinies the play of the contingent and the unforeseen.”
—H.A.L. (Herbert Albert Laurens)
