Increase of nerve regeneration capacity by new neurotrophic pyrimidine derivative MS-430

1. We studied whether a new neurotrophic pyrimidine compound, MS-430, can increase the regeneration length of the transected sciatic nerve in a silicone chamber gap of 14 mm. 2. The average length of regenerated myelinated axons in ten cases was 9.0+/-0 mm in the control group, 2.8+/-1.9 mm in the 1 mg/kg/day of the MS-430 group and 5.0+/-5.1 mm in the 3 mg/kg/day of the MS-430 group, indicating that the average length was significantly larger in the 3-mg group than that in the control group (P<0.05). 3. The results clearly showed that the MS-430 has promoting effects on nerve regeneration.
