With all these studies on these interesting entities, new metallo-anticancer drugs to at least partially replace existing Pt-based anticancers are anticipated. This review covers a brief description of Ru-based anticancer complexes and perspectives.<br /><br /> To evaluate the safety of four different dosages of alpha lipoic acid (400, 600, 800, and 1200 mg) as food supplement on adverse events related to alpha lipoic acid consumption and efficacy on glycemic status and lipid profile in subjects with euglycemia or dysglycemia.<br /><br /> We conducted a retrospective, observational study enrolling 322 patients, 83 taking 400 mg/day, 78 taking 600 mg/day, 80 taking 800 mg/day, and 81 taking 1200 mg/day alpha lipoic acid, respectively.<br /><br /> In the groups treated with alpha lipoic acid 800 and 1200 mg/day, we registered a reduction of FPG, TC, LDL-C, and Tg compared to baseline (p &lt; 0.05 for all with alpha lipoic acid 800 mg/day, and p &lt; 0.01 for all with alpha lipoic acid 1200 mg/day). The values recorded in the group treated with alpha lipoic acid 1200 mg/day were significantly lower compared to the ones obtained with alpha lipoic acid 400 mg/day. Moreover, alpha lipoic acid 1200 mg/day reduced Hs-CRP levels compared to baseline and compared to 400 mg/day (p &lt; 0.05 for both). In the group treated with alpha lipoic acid at 800 mg/day, 5 subjects with IFG and 1 subject with IGT returned euglycemic. In the group treated with alpha lipoic acid at 1200 mg/day, 11 subjects with IFG and 3 subjects with IGT returned euglycemic.

Adverse events did not differ among the four groups.<br /><br /> The chronic use (4 years) of a food supplement containing alpha lipoic acid is well tolerated, without significant differences between lower and higher dosages and improves glycemic status and lipid profile but only if administered at high dosage.<br /><br />The chronic use (4 years) of a food supplement containing alpha lipoic acid is well tolerated, without significant differences between lower and higher dosages and improves glycemic status and lipid profile but only if administered at high dosage.<br /><br /> Chronic psychosocial stress impairs memory function and leads to a depression-like phenotype induced by a persistent status of oxidative stress. <br /><br /> L. (St. John's wort) is widely used to relieve symptoms of anxiety and depression; however, its long-term use is associated with adverse effects. <br /><br /> Turra is closely related to <br /><br /> . Both plants belong to <br /><br /> family and share many biologically active compounds. Previous work by our group showed that methanolic extracts of <br /><br /> have potent antioxidant activity as well as high hypericin content, a component that proved to have stress-relieving and antidepressant effects by other studies. Therefore, we hypothesized that <br /><br /> would reduce stress-induced cognitive impairment in a rat model of chronic stress.<br /><br /> To determine whether chronic treatment with <br /><br /> protects against stress-associated memory deficits and to investigate a possible mechanism.<br /><br /> The radial arm water maze (RAWM) was used to test learning and memory in rats exposed to daily stress using the resident-intrud hippocampus.<br /><br /> Cyclophosphamide (CP) causes redox imbalance and its use is associated with marked cardiotoxicity that limits its clinical applications. The present study investigated the protective effects of acetovanillone (AV) and edaravone (ED) against CP-induced oxidative stress and cardiac damage, emphasizing the role of PI3K/Akt/mTOR and Nrf2 signaling.<br /><br /> Rats received either AV (100 mg/kg) or ED (20 mg/kg) orally for 10 days and CP (200 mg/kg) on day 7. At day 11, the rats were sacrificed, and samples were collected for analysis.<br /><br /> AV and ED ameliorated serum troponin I, CK-MB, LDH, AST and ALP, and prevented cardiac histological alterations in CP-intoxicated rats. Both treatments decreased cardiac lipid peroxidation and enhanced GSH, SOD and cytoglobin in CP-induced rats. AV and ED downregulated Keap1, whereas increased the expression of PI3K, Akt, mTOR and Nrf2 in the heart of rats received CP. Additionally, the binding modes of AV and ED to Keap1 were pinpointed in silico using molecular docking simulations.<br /><br /> AV and ED prevent CP cardiotoxicity by attenuating oxidative stress and tissue injury, and modulating cytoglobin, and PI3K/Akt/mTOR and Keap1/Nrf2 signaling. Therefore, AV and ED may represent promising agents that can prevent cardiac injury in patients receiving CP.<br /><br />AV and ED prevent CP cardiotoxicity by attenuating oxidative stress and tissue injury, and modulating cytoglobin, and PI3K/Akt/mTOR and Keap1/Nrf2 signaling. Therefore, AV and ED may represent promising agents that can prevent cardiac injury in patients receiving CP.<br /><br /> Ensartinib (ESB) is a novel anaplastic lymphoma kinase inhibitor (ALK) with additional activity against Abelson murine leukemia (ABL), met proto-oncogene (MET), receptor tyrosine kinase (AXL), and v-ros UR2 sarcoma virus oncogene homolog 1 (ROS1) and is considered a safer alternative for other ALK inhibitors. ESB chemical structure contains a dichloro-fluorophenyl ring and cyclic tertiary amine rings (piperazine) that can be bioactivated generating reactive intermediates.<br /><br /> In vitro metabolic study of ESB with human liver microsomes (HLMs) was performed and the hypothesis of generating reactive intermediates during metabolism was tested utilizing trapping agents to capture and stabilize reactive intermediates to facilitate their LC-MS/MS detection. Reduced glutathione (GSH) and potassium cyanide (KCN) were utilized as trapping agents for quinone methide and iminium intermediates, respectively.<br /><br /> Four in vitro ESB phase I metabolites were characterized. Three reactive intermediates including one epoxide and one iminium intermediates were characterized. ESB bioactivation is proposed to occur through unexpected metabolic pathways. The piperazine ring was bioactivated through iminium ions intermediates generation, while the dichloro-phenyl group was bioactivated through a special mechanism that was revealed by LC-MS/MS.<br /><br /> These findings lay the foundations for additional work on ESB toxicity. Substituents to the bioactive centers (piperazine ring), either for blocking or isosteric replacement, would likely block or interrupt hydroxylation reaction that will end the bioactivation sequence.<br /><br />These findings lay the foundations for additional work on ESB toxicity.
