Water-soluble betaines and amines based on thiacalix[4]arene scaffold as new cholinesterase inhibitors.

ABSTRACT

Novel ammonium and betaine derivatives of p-tert-butylthiacalix[4]arene in cone and 1,3-alternate conformation were synthesized with high yields for the first time. The obtained compounds form in water spherical nanoparticles. It was shown by molecular docking calculations and in vitro experiments that amino and betaine derivatives can inhibit acetylcholinesterase and butyrylcholinesterase on the level of pyridostigmine while the toxicity of the obtained compounds is much lower than that of pyridostigmine.
