Synthesis of new fenmetazole analogues with potential mixed α2-adrenergic antagonistic activity and noradrenaline-uptake inhibiting properties
摘要:
In the search for new antidepressants with a rapid onset of action, fenmetazole analogues, bearing a second phenyl ring in a position previously shown not to be detrimental to affinity and selectivity for the alpha-2-adrenoreceptors, were synthesized in an attempt to combine NA-uptake inhibition and blockade of the alpha-2-adrenoreceptors in the same molecule. Some of the new molecules showed enhanced affinity and selectivity for the alpha-2-adrenoreceptors compared to fenmetazole. Surprisingly, introduction of a phenyl ring in the structure of fenmetazole changed the agonistic action of the parent compound toward the alpha-1-adrenoreceptors into an antagonistic effect. However, none of the new derivatives showed in vitro NA-uptake inhibitory potency substantially different from the low activity of fenmetazole in this test.

of reactions with o-chloronitrobenzene by initial formation of σH adducts and slower formation of σCl adducts. Reversible formation of σH adducts followed by their fast transformation results in the formation of four different products with high selectivity. Slower addition in a position occupied by a chlorine atom to form σCl adducts results in a conventional SNAr reaction. These five reaction pathways
electrophilic nature of quinoxaline has been explored in the vicarious nucleophilic substitution (VNS) of hydrogen with various carbanions as nucleophiles in an attempt to develop a general method for functionalizing the heterocyclic ring. Only poorly stabilized nitrile carbanions were found to give the VNS products. 2-Chloroquinoxaline gave products of SNAr of chlorine preferentially. A variety of quinoxaline
