Nicotine et dérivés de nicotine
La nicotine et ses dérivés sont des alcaloïdes que l'on trouve couramment dans les plantes de tabac. Ces composés agissent comme des stimulants chez les mammifères, affectant la neurotransmission en agissant sur les récepteurs nicotiniques de l'acétylcholine. La nicotine et ses dérivés ont une large gamme d'effets biologiques, ce qui les rend importants pour la recherche en neurobiologie, en études sur l'addiction et en pharmacologie. CymitQuimica propose divers dérivés de la nicotine pour soutenir ce domaine de recherche.
