[Effect of BOF-A2 on experimental and spontaneous metastasis model of mouse colon 26].
We investigated the effects of BOF-A2 on the metastasis of colorectal cancer using artificial (experimental) and spontaneous metastasis of Colon 26 tumor cells. BOF-A2 suppressed pulmonary nodules in the artificial metastasis of Colon 26 tumor cells into the lung, and the T/C (%) was 53.1% at 20 mg/kg or 8.3% at 40 mg/kg. BOF-A2 also suppressed pulmonary nodules in the spontaneous metastasis of Colon 26 tumor cells into the lung, and the T/C (%) was 33.3% at 40 mg/kg in postoperative treatment, 33.3% at 10 mg/kg, or 16.7% at 20 mg/kg in preoperative treatment. These effects were accompanied by the prolongation of survival time at each dose. From these results, BOF-A2 showed antimetastatic activity and survival effect, and may be useful for adjuvant chemotherapy to prevent cancer from metastasis to the lung.
