Isolation of isoxanthopterin from human urine.
The pterins xanthopterin (2-amino-4:6-dihydroxypteridine) (Koschara, 1936) and biopterin (2amino 4 hydroxy-6-[1: 2-dihydroxypropyl (L-erythro)]-pteridine) (Patterson, Saltza & Stokstad, 1956) have been isolated from human urine. It has been suggested that the pterins 2-amino-4-hydroxypteridine-6-carboxylic acid, 2-amino-4-hydroxypteridine and isoxanthopterin (2-amino-4:7-dihydroxypteridine) are...
متن کاملIsolation of steroids from the urine of patients with adrenal cortical tumors and adrenal cortical hyperplasia; a new 17-ketosteroid, androstane-3 (alpha) 11-diol-17-one.
Information on the metabolism of the steroid hormones has been obtained largely by injection of known amount,s of the crystalline hormones and isolation of the steroids which subsequently appeared in the urine (1). Experiments of t’his type wit,h the adrenal hormones necessarily have been limited in scope by the limited available supply of crystalline adrenzl steroids. Some additional informati...
متن کاملTHE ISOLATION OF (r-DIHYDROTHEELIN FROM HUMAN PREGNANCY URINE
The quantitative determination of urinary estrogens is being applied widely as a research procedure in the study of normal and pathological conditions. Most investigators have limited their work to the estimation of total estrogenic potency, although it has been known for some time that the urine of pregnant women contains at least two estrogenic compounds, theelin and theelol. Experiments upon...
متن کاملThe isolation of crystalline erythritol from normal human urine.
With the finding that xylitol is an intermediate in the glucuronate-xylulose pathway (2, 3)) experiments were undertaken to determine whether this pentitol occurs in human urine. Instead of xylitol, the analyses led to the isolation of n-arabitol from pentosuric urine as well as nL-arabitol from normal urine (4). During the fractionation of urinary polyols on Dowex l-borate columns, eluates wer...
متن کاملSimple method for the isolation of 17-oxosteroid glucuronides from urine.
In order to study the hydrolysis, enzymatic or chemical, of the plasma and urinary steroid glucuronides, as well as the biosynthesis, the isolation of the individual 17-oxosteroids is an absolute necessity. Schneider and Lewbart (1959) employed counter-current distribution techniques to isolate several steroid glucuronides. Androsterone glucuronide was isolated by Edwards and Kellie (1956) and ...
