  Synthesis and preliminary pharmacological evaluation of some cytisine derivatives

  摘要：

  Thirty-one N-derivatives of cytisine were prepared in order to modify its pharmacological profile and to obtain compounds of potential therapeutic interest either at a peripheral or central level, particularly as nicotinic ligands with improved ability to cross the blood-brain barrier. Actually, with the introduction of different kinds of substituent on the basic nitrogen of cytisine a variety of activities were observed, both in vivo (analgesic, dopamine antagonism, antihypertensive, inhibition of stress-induced ulcers, antiinflammatory, protection from PAF-induced mortality, hypoglycemic) and in vitro (positive cardio-inotropic, beta-adrenergic antagonism, alpha(1)- and alpha(2)-antagonism, inhibition of PAF-induced platelet aggregation). Six randomly selected compounds were tested for the ability to recognize a central nicotinic receptor and four of them exhibited K-i values; In the range 30-163 nM. (C) 1999 Elsevier Science S.A.

  The reaction of cytisine with formalin in various solvents was studied. Methylene-bis-cytisine was produced in addition to the expected N-methylolcytisine in all solvents except acetone, in which N-(3-oxobutyl)cytisine was produced.

  研究了细胞素与福尔马林在各种溶剂中的反应。除了预期的N-羟甲基细胞素外，在所有溶剂中均产生了亚甲基双细胞素，但在丙酮中则产生了N-(3-氧代丁基)细胞素。
