Diabetic peripheral neuropathy (DPN), saponin of Momordica cymbalaria (SMC), neuroblastoma cells, aldose reductase, sorbitol dehydrogenase, Na K -ATPase


Objective: The natural product Momordica cymbalaria Fenzl has been in use considerably because of its antidiabetic activity. In this work, we have investigated the protective action of one of its phytoconstituent, a saponin, in peripheral neuropathy–a diabetic complication.

Methods: The saponin was isolated and identified by preparative high-performance liquid chromatography (preparative HPLC) and thin layer chromatography TLC). High glucose (56 mM)-mediated neuropathy was induced in NB-41A3 mouse neuroblastoma cells and the neuroprotective activity of the saponin was assessed by evaluating its effect on the two polyol pathway enzymes–aldose reductase (AR) and sorbitol dehydrogenase (SDH). The accumulation of intracellular sorbitol, activity of Na+K+-ATPase and production of pro-inflammatory cytokines IL-6, IL-1β and TNF-α were also investigated.

Results: The results showed a significant reduction in AR activity and intracellular accumulation of sorbitol on saponin treatment. Improvement in Na+K+-ATPase activity was evident with a noteworthy reduction in IL-6, IL-1β and TNF-α production.

Conclusion: These results suggest that the saponin possesses neuroprotective activity in diabetic peripheral neuropathy.

Keywords: Diabetic peripheral neuropathy (DPN), Saponin of Momordica cymbalaria (SMC), Neuroblastoma cells, Aldose reductase, Sorbitol dehydrogenase, Na+K+-ATPase
