Zur Kenntnis des Actinomycins C

The contribution of wood to the flavor of alcoholic beverages

“…Brockmann (147) took the data reported in previous studies (143)(144)(145)(146) and plotted the increase in solids against the observed increases in acids and esters with aging, and concluded that they were linearly related. Thus he concluded that the formation of acids and esters during the aging of whiskey was dependent upon some precursor which is extracted from the wood at the same rate as wood solids.…”

Cancer chemotherapy--the first twenty-five years.

“…They are formed during the growth of various Streptomyces species and most are mixtures of closely related chemical substances. Actinomycin C (Sanamycin) formerly had some reputation in Hodgkin's disease (Brockman and Grubhofer, 1950). Only actinomycin D is now in use.…”

Extraction

“…The most striking contribution of countercurrent distribution during the past year has probably been made in the polypeptide field. It has been used by Brink et al in purifying subtilin (12), by Brockmann et al in purifying polypeptide antibiotics from Actinomycetes (13)(14)(15), by Payne et al in purification of ACTH (67), by du Vigneaud and collaborators on vasopressin (87) and oxytocin (63), by Felix et al on clupein (33), by Velick and Udenfriend in their isotope dilution method (88) for amino acid analysis, and by Kenner (54) in purifying synthetic peptide derivatives. Where isolation of amino acids from hydrolyzates is desired, it is a useful tool (25,27,33).…”
