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:
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“The highest form of development is to govern one’s self.”
—Zerelda G. Wallace (1817–1901)
“Theories of child development and guidelines for parents are not cast in stone. They are constantly changing and adapting to new information and new pressures. There is no “right” way, just as there are no magic incantations that will always painlessly resolve a child’s problems.”
—Lawrence Kutner (20th century)
