Outline of Final Research Achievements

Accelerating effects of oxime derivative (ONO-1301) on angiogenesis/wound healing and its toxicity were studied using cells and animals. The study demonstrated that ONO-1301 promoted the production of various angiogenic/tissue regenerative factors, including hepatocellular growth factor (HGF) at cell levels, as well as angiogenesis. Furthermore, it was shown that intramuscular injection of ONO-1301 sustained-release preparations contained in biodegradable polymer to animals with lower limb ischemia accelerated angiogenesis at ischemic sites and restored blood flow and motor ability. Also, the safety of the preparations was confirmed in a toxicity test. As described above, it was suggested that an ONO-1301 ointment can be a wound-healing accelerator by inducing the production of various angiogenic/tissue regenerative factors at wound sites in a sustained manner.
