Nicorandil, a drug with both nitrate-like and ATP-sensitive potassium (KATP) channel-activating properties, has been well demonstrated in various aspects of myocardial infarction (MI), especially in inhibiting cell apoptosis and increasing coronary flow. However, the role of nicorandil in regulating inflammation and angiogenesis following myocardial infarction is still unrevealed. In the present study, we explored the effect of nicorandil on macrophage phenotype transition and inflammation regulation and the potential underlying mechanisms...

Congenital hyperinsulinism (CHI) is a rare genetic disorder characterized by excess insulin secretion, which results in hypoglycemia. Mutation of sulfonylurea receptor 1 (SUR1), encoded by the ABCC8 gene, is the main cause of CHI. Here, we captured the phenotype of excess insulin secretion through pancreatic differentiation of ABCC8-deficient stem cells generated by the CRISPR/Cas9 system. ABCC8-deficient insulin-producing cells secreted higher insulin than their wild-type counterparts, and the excess insulin secretion was rescued by nifedipine, octreotide and nicorandil...

Elevated intraocular pressure is the most prevalent and only treatable risk factor for glaucoma, a degenerative disease of the optic nerve. While treatment options to slow disease progression are available, all current therapeutic and surgical treatments have unwanted side effects or limited efficacy, resulting in the need to identify new options. Previous reports from our laboratory have established a novel ocular hypotensive effect of ATP-sensitive potassium channel (KATP) openers including diazoxide (DZ) and nicorandil (NCD)...

BACKGROUND: Effective treatments in heart failure (HF) patients with ischemic etiology have not been fully established. Nicorandil, combination of nitrate component and sarcolemmal adenosine triphosphate-sensitive potassium channel opener, is a potent vasodilator of coronary and peripheral vessels and has been used as an antianginal agent. Therefore, we examined impacts of nicorandil on cardiac mortality in ischemic HF patients. METHODS: Consecutive 334 HF patients with ischemic etiology were retrospectively registered and divided into 2 groups based on oral administration of nicorandil: nicorandil group (n = 116) and non-nicorandil group (n = 218)...

Evidences suggest that the presence of chronic kidney disease (CKD) is associated with cerebrovascular diseases related cognitive decline in dialysis patients. As mitochondrial dysfunction is implicated in neurodegenerative disorders, we hypothesized that changes in brain mitochondria occur due to vascular calcification induced by renal failure and the opening of the mitochondrial potassium channel using nicorandil may prevent its dysfunction. Brain tissues from rats with vascular calcification were studied...

Chronic angina pectoris is associated with considerable morbidity and mortality, especially if treated suboptimally. For many patients, aggressive pharmacologic intervention is necessary in order to alleviate anginal symptoms. The optimal treatment of stable ischemic heart disease (SIHD) should be the prevention of angina and ischemia, with the goal of maximizing both quality and quantity of life. In addition to effective risk factor modification with lifestyle changes, intensive pharmacologic secondary prevention is the therapeutic cornerstone in managing patients with SIHD...

Many scholars have studied the effect of nicorandil on perioperative myocardial protection in patients undergoing elective percutaneous coronary intervention (PCI), but results are inconsistent. Therefore, we performed this meta-analysis. Finally, 16 articles, including 1616 patients, were included into this meta-analysis. Meta-analysis results showed that: (1) Nicorandil can reduce the level of CK-MB after PCI, including at 6 hours, 12 hours, 18 hours and 24 hours. (2) Nicorandil can reduce the level of TnT after PCI, including at 6 hours, 12 hours, 18 hours and 24 hours...

The primary cardiotoxic action of doxorubicin when used as antitumor drug is attributed to the generation of reactive oxygen species (ROS) therefore effective cardioprotection therapies are needed. In this sense, the antianginal drug nicorandil has been shown to be effective in cardioprotection from ischemic conditions but the underlying molecular mechanism to cope with doxorubicin-induced ROS is unclear. Our in vitro study using the HL-1 cardiomyocyte cell line derived from mouse atria reveals that the endogenous nitric oxide (NO) production was stimulated by nicorandil and arrested by NO synthase inhibition...
