Anti-diabetic, diabetic neuropathy protective action and mechanism of action involving oxidative pathway of chlorogenic acid isolated from Selinum vaginatum roots in rats

Abstract

Phytopharmaceuticals have always reported vital roles in the field of medicine hence the need to investigate safe and efficient drugs for treating metabolic disorders is very significant. Roots of Selinum vaginatum have therapeutic benefits and are widely used by the people of the Rohtang region for treating diabetes and its associated complications. The present study focusses on the isolation of the bioactive from the S. vaginatum roots for estimating acute toxicity studies, anti-diabetic and diabetic neuropathy protective action along with the mechanism of action in STZ induced Wistar rats. The Selinum vaginatum roots were collected from the Rohtang region, Himalayas. Chlorogenic acid was isolated and underwent identification by UV, HPLC, 1 H NMR, C13 NMR, Mass, and FTIR spectroscopy methods. Chlorogenic acid was dosed at 10 and 20 mg/kg to observe the effects on experimentally induced diabetes and with time generated diabetic neuropathic complications. Biomarkers TNF-α, superoxide dismutase, nitrosative stress, lipid peroxide profile, and membrane-bound inorganic phosphate were analyzed. Histopathological evaluation of the liver and sciatic nerve was performed for all groups. Parameters like blood glucose levels, body weight, food intake, Thermal Hyperalgesia, Writhing, Cold Hyperalgesia Responses, Mechanical hyperalgesia, Grip Strength, Spontaneous Locomotor (Exploratory) Test, Neuromuscular Coordination tests, and lipid profile analysis showcased the anti-diabetic and diabetic neuropathy protective action of the drug. Inflammation, degradation, and necrosis were found to be reduced in the liver and sciatic nerve cells of treated groups. All the biomarkers used to analyze the oxidative pathway were significantly replenished indicates that chlorogenic acid produces these effects through this pathway.

Sphaeranthus indicus Linn ameliorates streptozotocin-induced experimental diabetic neuropathy by targeting oxidative stress-mediated alterations

“…Due to MESI and metformin therapy, typical signs of diabetes such as polyphagia, polydipsia, and polyuria were reduced, which in turn decreased excessive food and fluid consumption. MESI's effects on body weight, food and water ingestion, and urine production of diabetic rats are well matched with the past studies evaluating naringin [24], hesperidin [26], and chlorogenic acid [46]. During diabetes, the excess glucose present in the blood reacts with hemoglobin to form HbA1c, which is increased over a long period in diabetes mellitus [47].…”

“… 5 , 31 In line with earlier studies, diabetic rats showed amplified nociceptive responses in the acetic acid (abdominal stretching) and formalin tests (paw licking or biting behaviour). 30 , 32 The result obtained from this study demonstrated that ERB significantly attenuated acetic acid and formalin induced abdominal stretching and paw licking time, respectively in the treated diabetic rats.…”

“…Diabetic animals displayed significant hyperalgesia and increased sensitivity to pain stimulus in the hot plate, tail flick and von Frey test, which was consistent with previous studies. 5 , 28 , 30 Administration of EBR to diabetic rats markedly improved thermal, cold and mechanical hyperalgesia in the treated diabetic rats.…”
