Preclinical, Journal: Omarigliptin/rosinidin combination ameliorates cyclophosphamide-induced lung toxicity in rats: The interaction between glucagon-like peptide-1, TXNIP/NLRP3 inflammasome signaling, and PI3K/Akt/FoxO1 axis. (Pubmed Central) - Jul 28, 2024 Both omarigliptin and rosinidin exhibited a synergistic ability to augment the tissue antioxidant defenses, mitigate the inflammatory pathways, restore glucagon-like peptide-1 levels, modulate high mobility group box 1 (HMGB1)/receptors of advanced glycation end products (RAGE)/nuclear factor kappa B (NF-?B) axis, downregulate the fibrogenic mediators, and create a balance between the pathways involved in apoptosis and the autophagy signals in the pulmonary tissues. In conclusion, omarigliptin/rosinidin combination may be introduced as a novel therapeutic modality that attenuates the different forms of lung toxicities induced by cyclophosphamide.

Journal: Omarigliptin inhibits brain cell ferroptosis after intracerebral hemorrhage. (Pubmed Central) - Sep 7, 2023 In addition, the elevation of iron content, lipid peroxidation and FACL4 after ICH; and reduction of GPX4 and AIFM2; were mitigated by MK3102 in vitro and in vivo. The neuroprotective effect of MK3102 may be related to anti-ferroptosis by regulating GLP-1R after ICH injury.

Review, Journal: Insight into Structure Activity Relationship of DPP-4 Inhibitors for Development of Antidiabetic Agents. (Pubmed Central) - Aug 16, 2023 Additionally, various synthesis schemes were developed to make several commercially available DPP4 inhibitors such as vildagliptin, sitagliptin and omarigliptin. In conclusion, the use of halogenated scaffolds for the development of DPP-4 inhibitors is likely to be an area of increasing interest in the future.

Preclinical, Journal: Omarigliptin Protects the Integrity of the Blood-Brain Barrier After Intracerebral Hemorrhage in Mice. (Pubmed Central) - Jun 21, 2023 Importantly, MK3102 protected the integrity of the BBB after ICH, associated with decreased expression of MMP-9, and preservation of the tight junction proteins ZO-1 and Occludin on endothelial cells through putative degradation of MMP-9, and inhibition of the expression of CX43 on astrocytes. Omarigliptin protects the integrity of the BBB in mice after ICH injury.

Preclinical, Journal: Antidiabetic Omarigliptin Dilates Rabbit Aorta by Activating Kv Channels and the SERCA Pump. (Pubmed Central) - Sep 14, 2022 Pretreatment with the sarco/endoplasmic reticulum Ca -ATPase (SERCA) pump inhibitors thapsigargin and cyclopiazonic acid significantly reduced the vasodilatory effect of omarigliptin...Furthermore, pretreatment with the nitric oxide synthase inhibitor L-NAME or small-conductance Ca -activated K channel inhibitor apamin, together with the intermediate-conductance Ca -activated K channel inhibitor TRAM-34, did not influence the vasodilatory effect of omarigliptin. In conclusion, omarigliptin induced vasodilation in rabbit aortic smooth muscle by activating voltage-dependent K channels and the SERCA pump independently of other K channels, cAMP/PKA- and cGMP/PKG-related signaling pathways, and the endothelium.

Journal: Anti-Quorum Sensing Activities of Gliptins against Pseudomonas aeruginosa and Staphylococcus aureus. (Pubmed Central) - May 30, 2022 To test the anti-QS activities of gliptins, a detailed molecular docking study was conducted to evaluate the gliptins' binding affinities to P. aeruginosa and S. aureus QS receptors, which helped explain the anti-QS activities of gliptins, particularly sitagliptin and omarigliptin. In conclusion, this study evaluates the possible antivirulence and anti-QS activities of gliptins that could be promising novel candidates for the treatment of aggressive Gram-negative or -positive bacterial infections either alone or as adjuvants to other antibiotics.

Specifically, trelagliptin raised the risk of fracture, whereas voglibose and albiglutide showed benefit with statistical difference...Some drugs (omarigliptin, sitagliptin, vildagliptin, saxagliptin, empagliflozin, ertugliflozin, rosiglitazone, pioglitazone, and nateglinide) may increase the risk of fracture, while others (such as dulaglutide, exenatide, liraglutide, semaglutide, lixisenatide, linagliptin, alogliptin, canagliflozin, dapagliflozin, glipizide, gliclazide, glibenclamide, glimepiride, metformin, and insulin) may show benefits...When developing individualized treatment strategies, the clinical efficacy of anti-diabetic drugs must be weighed against their benefits and risks brought about by individual differences of patients. This Systematic Review was prospectively registered on the PROSPERO (https://www.crd.york.ac.uk/PROSPERO/, registration number CRD42020189464).

Preclinical, Journal: Omarigliptin Prevents TNF-α-Induced Cellular Senescence in Rat Aorta Vascular Smooth Muscle Cells. (Pubmed Central) - Jan 4, 2022 Importantly, our experiments revealed that blockage of silent information-regulator 1 (SIRT1) abolished the inhibitory effects of OMG on p53 acetylation, SA-β-gal activity, and telomerase activity in VSMCs. These results suggest that OMG may have the potential to delay or prevent the progression of age-related cardiovascular diseases by modulating the activity of SIRT1.

(Pubmed Central) - Sep 28, 2021 The omarigliptin and 600 μg NPY combined treatment, but neither alone, was also sufficient at preventing depressive-like behavior on the FST. The results demonstrate that: (1) SPS elicits several behavioral manifestations of PTSD in females; (2) early intervention with a high dose of intranasal NPY has therapeutic potential also for females; and (3) NPY cleavage by DPP4 may play a role in the higher dose requirement for females.
