Morphological and functional evaluation of the effect of novel pyrimidine derivatives on regeneration of the sciatic nerve in rats

Neurosci Lett. 2019 Jul 27:706:110-113. doi: 10.1016/j.neulet.2019.05.008. Epub 2019 May 9.

Abstract

Two novel pyrimidine derivatives, RG2 and RG6, were studied using a rat's model of peripheral nerve injury. Toe-spreading reflex and skin sensitivity to pinch in the foot were monitored to follow recovery of motor and sensory functions in the treated animals. The remyelation rate in the distal segment of the damaged nerve was also studied using morphological analysis of cross-sections of the nerve stained with methylene blue. The obtained data demonstrate a high stimulating effect of RG2 and RG6 on the restoration of motor and sensory functions of the sciatic nerve, as well as on the post-traumatic regeneration of myelin fibers. Possible mechanisms of the observed effects are discussed.
