Sixty-one indole derivatives containing oxindole, spiro-oxindole, and condensed-ring indole were prepared and their antitumor activity was examined using a solid type of Ehrlich carcinoma. 1-Methyl-3-(1-methylthio-1-morpholinomethylene) oxindole was found to have some antitumor effect, but no other derivatives were found effective.
