alinidine alinidine alinidine (st567) is a negative chronotrope that was developed in the 1970s and 1980s. it causes bradycardia by inhibiting the pacemaker current by altering the maximal channel conductance and alter the voltage threshold. the development of alinidine was halted because it was not sufficiently specific for its target. it also has a blocking effect on calcium channels and potassium channels. it also causes elongation of re-polarisation after an action potential. alinidineclinical dataatc codenonelegal statuslegal status in general: uncontrolled identifiers iupac name n-(2,6-dichlorophenyl)-n-(prop-2-en-1-yl)-4,5-dihydro-1h-imidazol-2-amine cas number33178-86-8 npubchem cid36354chemspider33429 yuniie7idj8ds1dchemblchembl278581 ycomptox dashboard (epa)dtxsid4022571 echa infocard100.164.275 chemical and physical dataformulac12h13cl2n3molar mass270.16 g·mol−13d model (jsmol)interactive image smiles clc2cccc(cl)c2n(/c1=n/ccn1)c\c=c inchi inchi=1s/c12h13cl2n3/c1-2-8-17(12-15-6-7-16-12)11-9(13)4-3-5-10(11)14/h2-5h,1,6-8h2,(h,15,16) ykey:oxtyveuaqhppmv-uhfffaoysa-n y ny (what is this?)
