Antihyperglycemic action of scopoletin needs to be validated before considering it for clinical trials. The present study explored antihyperglycemic action of scopoletin in high-fructose high-fat diet (HFHFD)–induced diabetes in rats. The animal study was performed using 48 rats, 6 in each group. HFHFD was administered for model induction for 74 days. Rats in Group I (normal control [NC]) and group II (experimental control [EC]) received normal saline and HFHFD, respectively, throughout the study. Groups III, IV, V, and VI received oral scopoletin (1 mg/kg [low dose, LD], 5 mg/kg [medium dose, MD], 10 mg/kg [high dose, HD]), and metformin (250 mg/kg; positive control [PC] for efficacy), respectively, once daily from day 60 to 74, in addition to HFHFD. Group VII (10 mg/kg oral scopoletin safety group) and VIII (0.1 mg/kg oral warfarin; PC for safety) were separately used for bleeding time-clotting time (BTCT) assessment on days 60, 68, and 74. Groups I, VII, and VIII rats were studied for safety assessment. Later, animals were sacrificed for histological examination. Scopoletin-treated groups showed a significant decline in glucose levels, especially in the MD (5.18 ± 0.12) and HD group (5.271 ± 0.11) in comparison to the EC (6.37 ± 0.05) on day 74 (P < .05). Two weeks after scopoletin treatment, β-cell function significantly improved (53.073 ± 4.67) in the MD group versus 29.323 ± 8.505 in the NC group (P < .05). A statistically significant difference was observed when the MD group (53.07 ± 4.67) was compared to the metformin-treated group (24.80 ± 3.24; P < .05). The safety assessment in the form of BTCT findings did not observe a difference among groups I, VII, and VIII (P > .05). The study showed that scopoletin dose-independently reversed insulin resistance. Consequently, scopoletin can be a potential candidate for antidiabetic drug development.

The putative hypolipidemic properties of scopoletin have not been fully confirmed due to a lack of validation in an irreversible chronic hyperlipidemia animal model. The druggability also needs to be studied in terms of bioavailability in the vascular compartment. Accordingly, we conducted a study to assess the hypolipidemic and pharmacokinetic behavior of scopoletin in the high-fructose high-fat diet (HFHFD)-induced dyslipidemia model in Wistar rats. A total of 42 rats were studied, with 6 in each of the 7 groups. A 60-day HFHFD opted for induction of dyslipidemia. Group I and groups II–VII received normal rat chow diet and HFHFD, respectively. Oral scopoletin (1, 5, 10 mg/kg) and atorvastatin 5 mg/kg were administered in groups III–VI, respectively, once daily for the next 15 days. A separate group, group VII, was used for the pharmacokinetic assessment comparing the scopoletin 10 mg/kg intraperitoneally (IP) in group VII versus the oral (group V). Pharmacokinetic blood sampling was performed on the 10th day of continuous once-daily therapy. Rats were sacrificed for the histological examination. All three scopoletin dosages significantly decreased the total cholesterol, low-density lipoproteins, and triglycerides (P < .05 for all), but not in a dose-dependent manner. Atherogenic Index of plasma, Castelli's risk indices, and histopathological findings confirmed the protective effect of scopoletin. The IP administration showed a 23.18% higher exposure than the oral route (P < .001 for area under the curve and P < .05 for concentration-maximum). This study confirms the hypolipidemic efficacy of scopoletin in a more robust irreversible model of dyslipidemia. Scopoletin's gut absorption in the disease state may also boost the initial phase exploratory clinical trial.
