    Notes: [Auszug] ATTEMPTS to prepare new analgesics have, for many years, been based almost exclusively on the morphine molecule, the peripheral groups of which may be modified considerably with relatively little effect on the biological activity. The synthetic drug ‘Pethidine’ (ethyl ...

    Notes: [Auszug] THE suggestion of Dewar1 that ring G of colchicine is 7-membered is interesting, and the arguments which he advances in favour of this merit consideration. I cannot, however, accept his statement that “Cohen, Cook and Hoe have now provided evidence that ring B must be ...

    Notes: [Auszug] WE have reported that we were unable to obtain any evidence of œstrogenic activity in rats with benzylidenepyruvic acid and furylidenepyruvic acid or their sodium salts1. These negative results were attributed by Friedmann2 to the use of insufficient doses (100 ...

    Notes: [Auszug] IN view of the results published by E. Friedmann in NATURE of April 20, we decided to investigate the effect upon ovariectomised rats of the two compounds specifically mentioned by him as œstrogenic, namely, sodium benzylidenepyruvate and sodium furylidene-pyruvate. These were prepared and ...

    Notes: [Auszug] SUGGESTIONS have sometimes been made that the biological action of carcinogenic hydrocarbons is preceded by conversion, probably by oxidation, into water-soluble derivatives which may more readily be conceived as able to exert a direct action on the cells which eventually become malignant than ...

    Notes: [Auszug] BY the following simple arrangement a single pile of glass plates may serve at once as polariser and analyser, and be used to study or to exhibit on a screen the interference colours with mica or crystal sections. It may not be new, but I have not seen it given anywhere. A beam of light is ...

    Notes: [Auszug] DEWAR1 has interpreted the chemistry of the mould metabolite, stipitatic acid, and of colchiceine (the methyl ether of which is the alkaloid colchicine) by postulating that they are derived from the hypothetical cycloheptatrienolone (I). This he termed ‘tropolone’, and he ...
