1d inhibits the growth of tumors derived from H1299 cells.

<p>H1299 cells were injected into athymic BALB/c nu/nu mice to induce tumors, and the mice were then treated with <b>1d</b> or DMSO. (A) Representative mice at the end of the treatment are shown. (B) Tumor volume was measured every 3 days after the first injection. (C) Images of all the excised tumors are shown. (D) The averaged tumor weights of the control versus the <b>1d</b>-treated group are depicted graphically. Data are the means ± SEM (n = 7). ***, p<0.001, compared with the control.
