    The actinomycins, particularly actinomycin-C, -D, and -K are effective in inhibiting the growth of some experimental animal as well as human tumours in extremely small doses in comparison with other antitumour drugs so far known. In view of the fact that the chemical structures of these antitumourous antibiotics possess the same chromophore grouping but differ in the polypeptido-lactone-ring moiety with respect to the kinds and number of amino-acids and the sequence of their arrangement, it is suspected that...

    The actinomycins, particularly actinomycin-C, -D, and -K are effective in inhibiting the growth of some experimental animal as well as human tumours in extremely small doses in comparison with other antitumour drugs so far known. In view of the fact that the chemical structures of these antitumourous antibiotics possess the same chromophore grouping but differ in the polypeptido-lactone-ring moiety with respect to the kinds and number of amino-acids and the sequence of their arrangement, it is suspected that the antitumour action of these compounds may arise from the chromophore grouping in common, whereas the peptido moiety functions as the carrier of the active group. In this investigation, therefore, 19 compounds derived from 2-amino-phenoxazone-(3) (Ⅱ) (see Table 7 and the reaction scheme) have been prepared for the purpose of studying the relation between chemical structure and antitumour action and also of searehing for the new type of synthetic antitumour compounds. To obtain the products a 6-step synthesis starting from 2-nitro-3-hydroxy-4-substituted benzoic acids (Ⅴ) was carried out, the sequence of the reactions being sketched .in the Chinese text.

    The band width of the ionic crystals with small mobility is so narrow, that suppling some impurities in the crystals deviates the periodic potential and the concept of ideal crystals is not applicable. For such crystals we must take H-L approach. In this work we calculated the mobility of the carriers, and refined the method of colculating the transition probality due to the fluctuation of impurity potential.

    1. In the gas chromatography, a plot of the logarithm of the retention volumes vs. 1/T (where T is the absolute temperature) gives a straight line. It is found that these straight lines for compounds of the same homologous series intersect at the same point. This point, is independent of the nature of the stationary liquid, and is approximately the same as the point of intersection of straight lines of the straturated vapor pressure vs. 1/T plots of the same family.2. A new equation is suggested for the calculation of the retention volumes (V_g) at various temperatures:log V_g-log V_g~0=m(1/T_0)where T is the absolute temperature; log V_g~0 and 1/T_0 are constants, depending on the nature of the functional group of the family, while independent of the nature of the stationary liquid and of the carrier gas; and m is a constant, which depends on the compound and the stationary liquid considered, but independent of temperature.When the values of log V_g~0 and 1/T_0 are known, from the retention volume compound known at one temperature, the retention volumes at other temperatures on the same sationary liquid can be calculated, with an error of 5—10%.3. The values of log V_g~0 and 1/T_0 of saturated hydrocarbons, olefinic hydrocarbons, alcohols, cycloparffins, aromatic hydrocarbons, aldehydes, ketons, esters, and alkyl halides are found as follows:paraffins olefines cyclopa-raffins armatic hydrocarbons alcohols aldehves ketolles esters alkyl halideslog V_g~0 -1.18 -0.03 -0.30 -0.48 -0.50 -0.30 -0.521/T_0×10~3 0.67 1.62 1.20 1.14 1.30 1.50 1.50The values of log V_g~0 and 1/T_0 for paraffins, aromatic hydrocarbons and alcohols were derived from experimental data on different stationary liquids, but those for the other homologues are derived from data on a single stationary liquid only.
