prothipendyl prothipendyl prothipendyl (brand names dominal, timovan, tolnate), also known as azapromazine or phrenotropin, is an anxiolytic, antiemetic, and antihistamine of the azaphenothiazine group which is marketed in europe and is used to treat anxiety and agitation in psychotic syndromes. it differs from promazine only by the replacement of one carbon atom with a nitrogen atom in the tricyclic ring system. prothipendyl is said to not possess antipsychotic effects, and in accordance, appears to be a weaker dopamine receptor antagonist than other phenothiazines. prothipendyl names preferred iupac name n,n-dimethyl-3-(10h-pyridobenzothiazin-10-yl)propan-1-amine identifiers cas number 303-69-5 y 3d model (jsmol) interactive image chemspider 14002 n echa infocard 100.132.989 ec number 214-958-4 pubchem cid 14670 unii 5o6vwa87va y comptox dashboard (epa) dtxsid50184389 inchi inchi=1s/c16h19n3s/c1-18(2)11-6-12-19-13-7-3-4-8-14(13)20-15-9-5-10-17-16(15)19/h3-5,7-10h,6,11-12h2,1-2h3 nkey: jttaupumolrvra-uhfffaoysa-n ninchi=1/c16h19n3s/c1-18(2)11-6-12-19-13-7-3-4-8-14(13)20-15-9-5-10-17-16(15)19/h3-5,7-10h,6,11-12h2,1-2h3key: jttaupumolrvra-uhfffaoyal smiles cn(c)cccn1c2=cc=cc=c2sc3=c1n=cc=c3 properties chemical formula c16h19n3s molar mass 285.40716 pharmacology atc code n05ax07 (who) except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references synthesis
