THE JOURNAL OF PHARMACOLOGY. 229 



The title of several members of this group consists in combining the 

 name of the acid, entire or in part, as a prefix or suffix with " pheneti- 

 din," "phenin," or "phen," for example. 



Class I. 



/%<?«acetin. Acet-p-phenetidin. 



PhenocoW. Glycocoll-p-phenetidin-hydrochlorid. 



Cxtrophen. Citric acid + p-phenetidin. 



Lactophenin. Lactyl phenetidin. 



Amygdophenin. Mandelate of p-phenetidin. 



Qlwcophenetidin. Condensation product of p-phenetidin and glucose. 



Class II. 



Kryofin (krvos = cold + phero = to catty). Title refers to its fever- 

 reducing properties. 



Malakin (malakos = soothing, mild), an analgesic. 



Scdatin. This title of valeryl phenetidin refers to its sedative proper- 

 ties. 



Malarin. Acetophenone-phenetidin citrate ; an anti-malarial. 



Class II. Pyrazolon Derivatives. 



Antipyrine (anti = against + puretos = fever) among the synonyms 

 we find 



Anodynin (an = negative + odynE = a pain). 

 Analgesine (an + ALGOS = a pain). 

 Parodyn (parodos = an animal). 



Tolypyrine—so called because of presence of tolyl (G 6 H 4 CH 3 ) groups 

 in place of the phenyl of antipyrine. 



Among the various derivatives of antipyrine, we have the following in 

 which the ending " pyrine" is retained, the prefix representing the com- 

 bining body. 



Sali-pyrine = antipyrine salicylate. 



Pheno-pyrine = compound of phenol and antipyrine. 



Reso-pyrine = compound of resorcin and antipyrine. 



Ferro-pyrine = compound of iron and antipyrine. 



Naphto-pyrine = compound of napthol and antipyrine. 



Iodo-pyrine = compound of iodin and antipyrine. 



Tussol (tussis = a cough) antipyrine mandelate employed in treatment 

 of whooping cough. 



Quinolin Derivatives. 



Owing to the complex nature of the various medicinal derivatives of 

 quinolin, the employment of chemical titles is entirely out of the question, 

 hence class two only is represented.
