Abstract
One of the key factors in the pathogenesis of diabetes and its complications is oxidative stress. To inhibit this process, antioxidants may be helpful. Herein, we focused on the protective properties of taxifolin spheroidal form (TS) in the streptozotocin rat model of diabetes mellitus. After 4 weeks of treatment with TS, the fasting blood glucose level of the diabetic animals decreased by 12% compared with the level right after the injection of streptozotocin. While the feed intake in the untreated diabetic rats increased by 5.3% compared with the healthy group, the TS-treated group showed a pronounced 15.3% decrease. Therapeutic administration of TS has a protective effect on the pancreas and the liver against the cytotoxic action of streptozotocin. The plasma antioxidant capacity of all diabetic groups appeared to be approximately 15% lower than in healthy rats with no significant difference between the TS-treated and untreated diabetic animals. Apparently, this can be attributed to taxifolin and plasma proteins binding. These data demonstrate the potential of TS in antidiabetic therapy.

Abstract
Diabetes mellitus (DM) is a chronic disease at all ages including childhood and puberty. Failure to treat DM can cause retinopathy, nephropathy and neuropathy. Endocrine and metabolic changes during the pubertal period complicate management of DM. Noopept is a cognitive enhancer that exhibits antidiabetic properties. We investigated the effect of noopept on the histopathology of the cornea, retina, kidney and pancreas in pubertal diabetic rats. We allocated 60 prepubertal male rats randomly into six groups of 10: untreated control (C), DM control (DC), noopept control (NC), DM + noopept (D + N), DM + insulin (D + I) and DM + insulin + noopept (D + I + N). DM was induced by streptozotocin in the DC, D + N, D + I and D + I + N groups. Noopept was administered to the NC, D + N and D + I + N groups; insulin was administered to the D + I and D + I + N groups for 14 days. On day 18 of the experiment, animals were sacrificed and eyes, kidneys and pancreata were excised for histological investigation. Renal tubule diameter and corneal and retinal thickness were increased significantly in DC groups compared to the control group. The D + I, D + N and D + I + N groups exhibited fewer DM induced pathological changes than the DC group. The D + I + N group exhibited no significant differences in renal tubule diameter and corneal and retinal thickness compared to the DC group. Our findings suggest that noopept is protective against DM end organ complications in streptozotocin induced diabetic pubertal rats.

Abstract
A low-molecular-weight nerve growth factor mimetic, compound GK-2 (bis-(N-monosuccinyl- L-glutamyl-L-lysine)hexamethylenediamide) that previously demonstrated antidiabetic activity in rats with streptozotocin-induced type 2 diabetes mellitus was studied on the model of diabetic neuropathy. It was found that in 8 weeks after diabetes mellitus development, untreated diabetic rats demonstrated impaired tactile sensitivity in von Frey test, while GK-2 therapy (7.5 mg/kg orally for 28 days) restored this parameter. The decrease of tactile sensitivity in diabetic neuropathy closely correlated with the severity of hyperglycemia (r=0.76). Our findings are consistent with the concept on the role of glucose toxicity and nerve growth factor deficiency in the pathogenesis of diabetic neuropathy and attest to feasibility of further studies of nerve growth factor mimetic GK-2 as a potential treatment for diabetes and diabetic neuropathy.

Abstract
BACKGROUND Growing evidences demonstrate a close relationship between type 2 diabetes (T2D) and neurodegenerative disorders such as Alzheimer's disease. The similarity of physiological and pathological processes, occurring in pancreatic β-cells and neurons over the course of these pathologies, allows to raise the question of the practicability of studying neuroprotective substances for their potential antidiabetic activity. OBJECTIVE This review analyzes studies of antidiabetic and cytoprotective action on pancreatic β-cells of the neuroprotective compounds that can attenuate the oxidative stress and enhance the expression of neurotrophins: low-molecular-weight NGF mimetic compound GK-2, selective anxiolytic afobazole, antidepressants lithium chloride and lithium carbonate on the rat streptozotocin model of T2D. RESULTS It was found that all above-listed neuroprotective substances have a pronounced antidiabetic activity. The decrease in the β-cells number, the average area of the pancreatic islets, as well as the violation of their morphological structure caused by the streptozotocin was significantly weakened by the therapy with the investigated neuroprotective substances. The extent of these morphological changes clearly correlates with the antihyperglycemic effect of these compounds. CONCLUSION The presented data indicate that the neuroprotective substances attenuating the damaging effect of oxidative stress and neurotrophins deficit cannot only protect neurons but also exert their cytoprotective effect towards pancreatic β-cells. These data may provide a theoretical basis for the further study of neuroprotective drugs as potential therapeutic options for T2D prevention and treatment.

Noopept Attenuates Diabetes-Mediated Neuropathic Pain and Oxidative Hippocampal Neurotoxicity via Inhibition of TRPV1 Channel in Rats. Mol Neurobiol 2021; 58:5031-5051.

Abstract
Neuropathic pain and oxidative neurotoxicity are two adverse main actions of diabetes mellitus (DM). The expression levels of calcium ion (Ca2+) permeable TRPV1 channels are high in the dorsal root ganglion (DRGs) and hippocampus (HIPPO). TRPV1 is activated by capsaicin and reactive free oxygen radicals (fROS) to mediate peripheral neuropathy and neurotoxicity. Noopept (NP) acted several protective antioxidant actions against oxidative neurotoxicity. As DM is known to increase the levels of fROS, the protective roles of antioxidant NP were evaluated on the DM-mediated neurotoxicity and neuropathic pain via the modulation of TRPV1 in rats. Thirty-six rats were equally divided into control, NP, DM (streptozotocin, STZ), and STZ + NP groups. A decrease on the STZ-mediated increase of neuropathic pain (via the analyses of Von Frey and hot plate) and blood glucose level was observed by the treatment of NP. A protective role of NP via downregulation of TRPV1 activity on the STZ-induced increase of apoptosis, mitochondrial fROS, lipid peroxidation, caspase -3 (CASP-3), caspase -9 (CASP-9), TRPV1 current density, glutathione (GSH), cytosolic free Zn2+, and Ca2+ concentrations in the DRGs and HIPPO was also observed. The STZ-mediated decrease of glutathione peroxidase, GSH, vitamin E, and β-carotene concentrations in the brain cortex, erythrocyte, liver, kidney, and plasma was also attenuated by the treatment of NP. The STZ-mediated increase of TRPV1, CASP-3, and CASP-9 expressions was decreased in the DRGs and HIPPO by the treatment of NP. In conclusion, the treatment of NP induced protective effects against STZ-induced adverse peripheral pain and HIPPO oxidative neurotoxicity. These effects might attribute to the potent antioxidant property of NP.

Abstract
There are largely unknown associations between changes in pain behavior responses during persistent peripheral inflammation and spinal cell alteration such as apoptosis. Some evidence suggests that microglia and microglia related mediators play notable roles in induction and maintenance of central nervous system pathologies and inflammatory pain. By considering those relationships and microglia related nootrophic factors, such as the Brain Derived Neurotrophic Factor (BDNF) in CNS, we attempted to assess the relationship between microglia dependent BDNF and its precursor with pain behavior through spinal cell apoptosis as well as the effect of Noopept on this relationship. Persistent peripheral inflammation was induced by a single subcutaneous injection of Complete Freund's Adjuvant (CFA) on day 0. Thermal hyperalgesia, paw edema, microglial activity, microglia dependent BDNF, pro-BDNF expression, and apoptosis were assessed in different experimental groups by confirmed behavioral and molecular methods on days 0, 7, and 21 of the study. Our findings revealed hyperalgesia and spinal cell apoptosis significantly increased during the acute phase of CFA-induced inflammation but was then followed by a decrement in the chronic phase of the study. Aligned with these variations in spinal microglial activity, microglia dependent BDNF significantly increased during the acute phase of CFA-induced inflammation. Our results also indicated that daily administration of Noopept (during 21 days of the study) not only caused a significant decrease in hyperalgesia and microglia dependent BDNF expression but also changed the apoptosis process in relation to microglia activity alteration. It appears that the administration of Noopept can decrease spinal cell apoptosis and hyperalgesia during CFA-induced inflammation due to its direct effects on microglial activity and microglia dependent BDNF and pro-BDNF expression.

Abstract
Previous in vitro and in vivo studies revealed the neuroprotective effect of anxiolytic Afobazole. Based on similarities in the regulation of functions of neurons and β cells, we studied the effect of Afobazole on streptozotocin (STZ) model of type 2 diabetes in Wistar rats. Immunohistochemical analysis showed that the decrease in the number of β cells and a violation of their morphological structure caused by STZ were significantly alleviated by Afobazole administration (10 mg/kg orally for 28 days) to diabetic animals. A correlation between morphometric data and blood glucose level was revealed. A possible role of σ1-receptors in the cytoprotective effects of Afobazole in respect to pancreatic β cells is discussed.

Abstract
In experiments on BALB/c mice, prediabetes was modeled by administration of streptozotocin in a dose of 130 mg/kg. DNA damage was assessed by the method of DNA comets. Noopept (0.5 mg/kg intraperitoneally) was administered for 14 days before and for 6, 13, or 14 days after streptozotocin administration. Despite moderate hyperglycemia and increased malondialdehyde level, the intensity of DNA damage in cells of the pancreas, liver, and kidneys significantly surpassed the control values. Noopept normalized these parameters due to its pronounced antigenotoxic effect. For both the damaging effect of streptozotocin and the normalizing effect of Noopept, DNA changes manifested mainly in terms of atypical DNA comets. Our findings confirm the role of DNA damage in the pathogenesis of diabetes. They indicate the possibility of pharmacological protection of pancreatic β cells with the neuroprotective drug and provide an important argument in favor of the hypothesis about the similarity of the mechanisms of formation of the resistance of neurons and β cells to the cytotoxic influences.

Abstract
AIM Type 1 diabetes (T1DM) is a common chronic disease in childhood. Increasing insulin resistance in puberty gives rise to higher doses of insulin usage in treatment. Of this reason new approaches in treatment are needed. Noopept researches suggest it to have anti-diabetic properties. We tried to determine the effects of noopept on pubertal diabetes. MAIN METHOD The research was made with 60 prepubertal, 28 day-old, male, Sprague Dawley rats. The rats were divided into randomised 6 groups (n = 10/group). i) Control, ii) Diabetes Control, iii) Noopept Control, iv) Diabetes + Noopept, v) Diabetes + Insulin, vi) Diabetes + Insulin + Noopept. T1DM model was induced by streptozotocin on postnatal 28th day. 0.5 mg/kg noopept and 1 IU insulin were administered intraperitoneally for 14 days. Blood glucose and body weight measurements, puberty follow-up and MWM tests were performed. Hippocampus, hypothalamus and testis were evaluated histologically. Hypothalamic GnRH and kisspeptin were studied immunohistochemically. Serum LH, FSH and insulin, hippocampal homogenate NGF and BDNF levels were determined by ELISA. KEY FINDINGS Delayed puberty was normalized by noopept (p < 0.05). Blood glucose levels were lower in noopept-administered diabetic groups (p < 0.05). Noopept decreased HOMA-IR in insulin administered diabetic group (p < 0.05). Number of degenerated cells in hippocampus and testis were higher in diabetes control group when compared with other groups (p < 0.05). GnRH immunoreactivity in Diabetes + Noopept group was increased when compared to insulin + noopept group (p = 0.018). There was no difference in kisspeptin, serum LH, FSH, hippocampal NGF-BDNF levels and spatial learning assessment among groups (p > 0.05). SIGNIFICANCE Noopept may have positive effect in treatment of pubertal diabetes.

Abstract
We studied antidiabetic effects and cytoprotective activity of two lithium salts (lithium chloride and lithium carbonate) on the model of streptozotocin-induced diabetes mellitus type 2 in Wistar rats. Using the method of β-cells detection with antibodies to insulin, we demonstrated that streptozotocin reduced the number of β-cells and impaired their morphological structure. Both lithium preparations administered to diabetic animals for 28 days in doses of 10 and 8.9 mg/kg, respectively, attenuated the damaging effect of streptozotocin. This cytoprotective effect of lithium salts manifested in weakening of hyperglycemia, polyphagia, polydipsia, and weight loss. A satisfactory correlation between the morphometric data and blood glucose levels was revealed. The mechanisms of the multitarget action of lithium salts are discussed.
