Serotonin and its methylated derivatives in human urine.
Substances with pharmacological properties similar to those of serotonin (5-hydroxytryptamine) have been found in human and dog urine and in rat, rabbit, and dog brain by Twarog and Page (1). Eluates of chromatograms of urine showed greatest activity from areas having the same RF value as serotonin. Since then, these eluates have been rechromatographed and other positive indole spots have appea...
متن کاملSome studies on cytisine and its methylated derivatives.
1. In mice cytisine hydrochloride is less toxic intravenously than nicotine hydrogen tartrate, but more toxic by intraperitoneal or oral administration. Compared with cytisine, caulophylline hydrogen iodide is one-fifth to one-tenth as toxic and caulophylline methiodide is less than one-thirtieth as toxic.2. The surprising low oral toxicity of cytisine and nicotine may be ascribed to the method...
متن کامل13C-nuclear magnetic resonance investigations of xanthine and some of its N-methylated derivatives.
The 13C-Nuclear Magnetic Resonance spectra of xanthine, 1,3-dimethyl-xanthine (theophylline), 3,7-dimethyl xanthine (theobromine) and 1,3,7-trimethylxanthine (caffeine) were obtained and the lines assigned. Protonationand N-Methylation parameters are derived by comparison of the 13C-chemical shifts of the protonated cations with those of the neutral molecules and also with those of the xanthine...
متن کاملhydrochlorothiazide detection in urine samples by hplc-dad and experimental design dispersive l-l microextraction
hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...
A convenient method to generate methylated and un-methylated control DNA in methylation studies
Methylated and un-methylated control DNA is an important part of DNA methylation studies. Although human and mouse DNA methylation control sets are commercially available, in case of methylation studies on other species such as animals, plants, and bacteria, control sets need to be prepared. In this paper a simple method of generating methylated and un-methylated control DNA is described. Whole...
