Curare is a well-known nicotinic antagonist that acts at the neuromuscular junction, blocking the action of acetylcholine at nicotinic receptors, leading to muscle paralysis. Botox (Botulinum toxin) works by preventing the release of acetylcholine, thus indirectly affecting nicotinic receptor activity by reducing acetylcholine availability. Atropine, however, is a muscarinic antagonist and does not directly block nicotinic receptors.
