Anti-tumor efficacy of C-1748 and C-1860, C-1872, C-1873 in human TSU xenografts in nude mice. Animals were randomized into treatment and control groups (six mice/group). Treatment was started when tumors were palpable (40 mm3) and continued once a week for six weeks. Tumor growth was measured using Vernier calipers and tumor volume calculated.
