A novel combretastatin A-4 derivative, AC7700, strongly stanches tumour blood flow and inhibits growth of tumours developing in various tissues and organs.
Bottom Line: In every tumour, tumour blood flow began to decrease immediately after AC7700 administration and reached a minimum at approximately 30 min after injection.These results demonstrate that AC7700 is effective for tumours growing in various tissues and organs and for metastases.We conclude that tumour blood flow stanching induced by AC7700 may become an effective therapeutic strategy for all cancers, including refractory cancers because the therapeutic effect is independent of tumour site and specific type of cancer.

Mentions: Inhibition of SLC tumour growth caused by AC7700 in the tumour developing in a transparent chamber. Tumour size at the start of observation was defined as 100%. During the 48 h after a single i.v. administration of 10 mg kg−1 AC7700, tumour size did not change at all (solid circle) (n=4). In contrast, tumours in the control group continued to grow (open circle) (n=4). Tumour area doubling time was 41.7±11.4 h.
