The number of diabetic patients has risen dramatically in recent decades, owing mostly to the rising incidence of type 2 diabetes mellitus (T2DM). Several oral antidiabetic medications are used for the treatment of T2DM including, α-glucosidases inhibitors, biguanides, sulfonylureas, meglitinides, GLP-1 receptor agonists, PPAR-γ agonists, DDP4 inhibitors, and SGLT2 inhibitors. In this review we focus on the possible effects of SGLT2 inhibitors on different body systems. Beyond the diabetic state, SGLT2 inhibitors have revealed a demonstrable ability to ameliorate cardiac remodeling, enhance myocardial function, and lower heart failure mortality. Additionally, SGLT2 inhibitors can modify adipocytes and their production of cytokines, such as adipokines and adiponectin, which enhances insulin sensitivity and delays diabetes onset. On the other hand, SGLT2 inhibitors have been linked to decreased total hip bone mineral deposition and increased hip bone resorption in T2DM patients. More data are needed to evaluate the role of SGLT2 inhibitors on cancer. Finally, the effects of SGLT2 inhibitors on neuroprotection appear to be both direct and indirect, according to scientific investigations utilizing various experimental models. SGLT2 inhibitors improve vascular tone, elasticity, and contractility by reducing oxidative stress, inflammation, insulin signaling pathways, and endothelial cell proliferation. They also improve brain function, synaptic plasticity, acetylcholinesterase activity, and reduce amyloid plaque formation, as well as regulation of the mTOR pathway in the brain, which reduces brain damage and cognitive decline.

Heat-shock proteins are upregulated in cancer and protect several client proteins from degradation. Therefore, they contribute to tumorigenesis and cancer metastasis by reducing apoptosis and enhancing cell survival and proliferation. These client proteins include the estrogen receptor (ER), epidermal growth factor receptor (EGFR), insulin-like growth factor-1 receptor (IGF-1R), human epidermal growth factor receptor 2 (HER-2), and cytokine receptors. The diminution of the degradation of these client proteins activates different signaling pathways, such as the PI3K/Akt/NF-κB, Raf/MEK/ERK, and JAK/STAT3 pathways. These pathways contribute to hallmarks of cancer, such as self-sufficiency in growth signaling, an insensitivity to anti-growth signals, the evasion of apoptosis, persistent angiogenesis, tissue invasion and metastasis, and an unbounded capacity for replication. However, the inhibition of HSP90 activity by ganetespib is believed to be a promising strategy in the treatment of cancer because of its low adverse effects compared to other HSP90 inhibitors. Ganetespib is a potential cancer therapy that has shown promise in preclinical tests against various cancers, including lung cancer, prostate cancer, and leukemia. It has also shown strong activity toward breast cancer, non-small cell lung cancer, gastric cancer, and acute myeloid leukemia. Ganetespib has been found to cause apoptosis and growth arrest in these cancer cells, and it is being tested in phase II clinical trials as a first-line therapy for metastatic breast cancer. In this review, we will highlight the mechanism of action of ganetespib and its role in treating cancer based on recent studies.

Ulcerative colitis is an idiopathic disease that is widely incident worldwide. Canagliflozin, antidiabetic agent, exhibited significant anti-inflammatory effects in a variety of animal models. Additionally, hyaluronic acid is considered one of the key players in the tissue regeneration process. It has been proven to modulate inflammation and cellular migration, which are the main phases of wound healing. The combination of hyaluronic acid with chitosan in microsphere fabrication was anticipated to reveal a synergistic muco-adhesiveness potential with additional advantage of the chitosan penetration enhancing effect. The current study aimed to explore the potential of canagliflozin-loaded chitosan-hyaluronic acid microspheres intrarectal administration to mitigate acetic acid-induced colitis in rats. Colon tissues were examined for macroscopic and microscopic pathological changes. ELISA and qRT-PCR techniques were applied for the detection of cytokines involved in the AMPK/NF-κB/NLRP3 axis. Intrarectal administration of this formula alleviated colitis severity, which was reflected by the reduced DAI, MES, colonic weight/length ratio and histopathological scoring values. Interestingly, canagliflozin-loaded chitosan-hyaluronic acid microspheres significantly enhanced AMPK phosphorylation and depressed NF-κB and NLRP3 expression leading to a subsequent reduction in caspase-1 cleavage and the inhibition of several inflammatory cytokines, including IL-1β, and IL-18. Overall, the current study revealed that the protective effects of the formula against acetic acid-induced colitis are primarily mediated via augmenting AMPK phosphorylation and its consequences of NF-κB inactivation. Since canagliflozin is not associated with hypoglycemic effects, clinical application of canagliflozin-loaded chitosan-hyaluronic acid microspheres represent a novel therapeutic option for the treatment of patients with ulcerative colitis.

Pulmonary fibrosis (PF) is a life-threatening disorder with a very poor prognosis. Because of the complexity of PF pathological mechanisms, filling such an unmet medical need is challenging. A number of pulmonary diseases have been linked to the activation of NF-κB and the NLRP3 inflammasome. Coomassie brilliant blue G-250 (CBBG) is proved to be a safe highly selective P2×7R antagonist with promising consequent inactivation of NLRP3 inflammasome. This is the first report to investigate the effect of CBBG on the bleomycin-induced lung fibrosis in rats. Our findings revealed that CBBG resulted in a significant improvement in histological features and oxidative status biomarkers of bleomycin-exposed lung tissue. Additionally, CBBG repressed collagen deposition as indicated after the analysis of hydroxyproline, TGF-β, PDGF-BB, TIMP-1, MMP-9, Col1a1, SMA and ICAM-1. It also exhibited anti-inflammatory potential as revealed by the determination of TNF-α, IL-1β, IL-18, MCP-1 in the lung tissue. In the bronchoalveolar lavage, the total protein and the LDH activity were substantially reduced. The lung protective effects of CBBG might be attributed on the one hand to the inhibition of NLRP3 inflammasome and on the other hand to the inactivation of NF-κB. Decreased levels of phospho-p65 and its DNA-binding activity as well as the analysis of TLR4 confirmed NF-κB inactivation. Caspase-1 activity is suppressed as a consequence of inhibiting NLRP3 inflammasome assembly. To conclude, CBBG may act as a primary or adjuvant therapy for the management of PF and therefore it may pose an opportunity for a novel approach to an unmet medical need.
