Metabolite Identification
Common NameEnprofylline
DescriptionEnprofylline, also known as 3-propylxanthine or enprofilina, belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. Enprofylline is a drug which is used in the management of symptoms of asthma. also used in the treatment of peripheral vascular diseases and in the management of cerebrovascular insufficiency, sickle cell disease, and diabetic neuropathy. Enprofylline is an extremely weak basic (essentially neutral) compound (based on its pKa). Xanthine bearing a propyl substituent at position 3.
