摘要:A new class of herbicidal compounds consisting of 3,6dialkylisoxazolo(3,4-d)pyrimidin-4-ones exhibits pre-emergence and post-emergence herbicidal activity, controlling effectively a wide spectrum of grassy and broad-leafed plant species at rates below one-half pound per acre. The synthesis of members of this class is described in detail, and the utility of representative compounds is exemplified.

摘要:Certain 3-oxo-prop-1-enyl purine and pyrimidine derivatives and the corresponding nucleosides have been prepared. These compounds exhibit interesting and valuable cytotoxic activity. This cytotoxicity is of special interest in that it appears to inhibit DNA reproduction without affecting RNA or protein synthesis.
