バナデートは、摘出ラット脂肪組織の穎粒画分に存在するチロシンキナーゼ(PTK)、ミエリン塩基性蛋白質キナーゼ(MBPK)、cAMPホスホジエステラーゼ(PDE)の活性を促進した。部分精製PDE活性はPTKやMBPK画分の添加によって増強した。MBPK画分はウエスタンプロット解析によってMAPキナーゼ(MAPK)を含むことが確認された。これからの結果は、バナデートがバナデート感受性PTKによるMBPK、恐らくMAPK、の活性化を介してPDEの活性を増強することを示唆する。

The antitumor activities of 4, 5-bis(ethyleneimino)-1, 2-benzoquinone (OBE), 2, 5-bis(ethyleneimino)-1, 4-benzoquinone (PBE), and 4-ethyleneimino-1, 2-naphthoquinone (NQE) were investigated in Ehrlich carcinoma. OBE was effective not only in prolonging the life-span of mice bearing Ehrlich ascites carcinoma but also in retarding the growth of the solid form of the same tumor. This compound was proved to be effective even in a smaller dose than the minimum effective dose of PBE, with lower toxicity than the latter. With NQE, the mice bearing the same ascites tumor did not survive longer than the control.Ratio of the number of neutrophils to lymphocytes (N/L) in the peripheral blood was compared with the non-treated and the treated groups of animal bearing the tumor. Generally speaking, the more progressed the growth of the ascites tumor was, the greater the value of N/L, but such increase of N/L was eventually observed in case of leucopenia induced by these agents. It may therefore be said that the observation of change of N/L should be considered as an element for evaluation of the result of screening experiment.

Dimethanesulphonylthioalkanes and analogous compounds were synthesized by the reaction of corresponding sodium thiosulphonate and appropriate dibromide to test the carcinostatic activity compaed with Myleran. It was found that some of these compounds inhibited pronouncedly the growth of the solid tumor produced by Ehrlich ascites carcinoma cells.
