In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Search for anticholinergic compounds. XLV. Structure and pharmacological activity of some esters of alkylamino acids: piperidino-, morpholino-, dicyclohexylamino-, phenylcyclohexylamino-, diphenylamino-, benzylphenylamino-, and benzylcyclohexylaminoacetic acids, published in 1985, which mentions a compound: 3235-67-4, Name is 1-Piperidineacetic Acid, Molecular C7H13NO2, Product Details of 3235-67-4.
The anticholinergic activity of a number of esters of acetic and aminoacetic acid derivatives was assessed as a function of the Schild index value. The highest activity was observed when piperidine was part of the alc. moiety and the acid moiety contained a branched substituent. With branched substituents in both the acid and the alc. moiety, activity decreased markedly. Aminoacetate esters were more active than the analogous acetate esters, the presence of 2 -O-C-C-N- groups in the mol. apparently being the reason behind this observation. 2-(1-Piperidinyl)ethyl diphenylaminoacetate [102964-41-0] was more active than pipethanate [4546-39-8].
As far as I know, this compound(3235-67-4)Product Details of 3235-67-4 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
