Description Tubocurarine is a non-depolarizing neuromuscular blocking agent and the first identified curare alkaloid.[A216008] Curare is one of the names used to describe plant-derived poisons used by indigenous South Americans to coat the tips of hunting arrows and darts, which were typically derived from plants of the genera _Chondrodendron_ and _Strychnos_.[A216008] Tubocurarine is a benzylisoquinoline derivative and shares this structural backbone with a number of plant-derived alkaloids, including [morphine] and [papaverine].[A216028] It was first isolated by Harold King in 1935 and was used clinically to induce neuromuscular blockade during surgeries, particularly those involving the abdomen.[A216038] Tubocurarine's clinical use was limited by its relatively long duration of action (30-60 minutes)[A216038] and a number of significant side effects.[A216048] Safer and more pharmacokinetically favorable non-depolarizing neuromuscular blockers, such as [rocuronium], have largely replaced the use of tubocurarine in the clinical setting.[A216048]
