[Derivatives of lupinin and epilupinin as ligands of various cholinesterases].

ABSTRACT

Literature data have been summarized on interaction of cholinesterases of some mammals and arthropods with a group of isomer derivatives of alkaloid lupini and its epimer epilupinin. As substrates of cholinesterases of several mammals there are studied 8 acetates containing in their molecules the chinolysidin bicycle with different structure of N-alkyl radical, which showed certain elements of specificity of action. For 2 isomer esters that are derivatives of the protonated base of the lupinin and epilupinin structures, differences in their substrate characteristics were revealed. The polyenzyme analysis if anticholinesterase efficiency was performed for 30 organophosphorus inhibitors that are dialkoxyphosphorus derivatives of lupinin and epilupinin; as a result, quite a few peculiarities of their action depending on their structure were revealed. Several tested compounds turned out to act as specific inhibitors of cholinesterases of some mammals and arthropods.
