Biochem Pharmacol 2024; 222:116096. [PMID: 38423188 DOI: 10.1016/j.bcp.2024.116096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 01/29/2024] [Accepted: 02/26/2024] [Indexed: 03/02/2024]
Abstract
Calcium channel blockers (CCBs) are commonly used as antihypertensive agents. While certain L-type CCBs exhibit antiatherogenic effects, the impact of Cav3.1 T-type CCBs on antiatherogenesis and lipid metabolism remains unexplored. NNC 55-0396 (NNC) is a highly selective blocker of T-type calcium channels (Cav3.1 channels). We investigated the effects of NNC on relevant molecules and molecular mechanisms in human THP-1 macrophages. Cholesterol efflux, an indicator of reverse cholesterol transport (RCT) efficiency, was assessed using [3H]-labeled cholesterol. In vivo, high cholesterol diet (HCD)-fed LDL receptor knockout (Ldlr-/-) mice, an atherosclerosis-prone model, underwent histochemical staining to analyze plaque burden. Treatment of THP-1 macrophages with NNC facilitated cholesterol efflux and reduced intracellular cholesterol accumulation. Pharmacological and genetic interventions demonstrated that NNC treatment or Cav3.1 knockdown significantly enhanced the protein expression of scavenger receptor B1 (SR-B1), ATP-binding cassette transporter A1 (ABCA1), ATP-binding cassette transporter G1 (ABCG1), and liver X receptor alpha (LXRα) transcription factor. Mechanistic analysis revealed that NNC activates p38 and c-Jun N-terminal kinase (JNK) phosphorylation, leading to increased expression of ABCA1, ABCG1, and LXRα-without involving the microRNA pathway. LXRα isrequired for NNC-induced ABCA1 and ABCG1 expression. Administering NNC diminished atherosclerotic lesion area and lipid deposition in HCD-fed Ldlr-/- mice. NNC's anti-atherosclerotic effects, achieved through enhanced cholesterol efflux and inhibition of lipid accumulation, suggest a promising therapeutic approach for hypertensive patients with atherosclerosis. This research highlights the potential of Cav3.1 T-type CCBs in addressing cardiovascular complications associated with hypertension.

Blood Pressure Reducing Potential and Renoprotective Action of Cilnidipine Among Hypertensive Patients Suffering From Chronic Kidney Disease: A Meta-Analysis. Cureus 2023; 15:e37774. [PMID: 37213948 PMCID: PMC10194430 DOI: 10.7759/cureus.37774] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/18/2023] [Indexed: 05/23/2023] Open
Abstract
Hypertension is a risk factor for cardiovascular diseases which also causes progressive kidney damage leading to chronic kidney disease (CKD), so the rate of progression of CKD can be controlled by reducing blood pressure (BP). Many anti-hypertensive drugs are available. Cilnidipine is a new-generation calcium channel blocker (CCB). This meta-analysis is aimed to generate pooled evidence about the effectiveness of cilnidipine as an anti-hypertensive and to explore its reno-protective actions. Pubmed, Scopus, Cochrane Library, and Google Scholar were searched from January 2000 to December 2022 to include the studies. The pooled mean difference, along with 95% CI, was computed using Revman 5.4.1 software (Revman International, Inc., New York City, New York). The Cochrane risk-of-bias assessment tool was used for bias assessment. This meta-analysis was registered in PROSPERO with Reg. no. CRD42023395224. This meta-analysis included seven studies with 289 participants in the intervention group and 269 in the comparator group, and were selected from Japan, India, and Korea. Systolic blood pressure (SBP) was significantly reduced in cilnidipine treated group among hypertensives with CKD subjects weighted mean difference (WMD) was 4.33, and the 95% confidence interval (CI) was 1.26 to 7.31 as compared to the other group. Cilnidipine also shows a significant reduction in proteinuria with WMD 0.61 and 95% CI 0.42 to 0.80. Both groups were similar in adverse drug reactions (ADR). Cilnidipine is a more effective anti-hypertensive as compared to Amlodipine or other CCBs, mainly in reducing SBP. Besides this, cilnidipine also shows better reno-protective action because it also significantly reduces proteinuria in such patients.

[PMID: 36536953 PMCID: PMC9750845 DOI: 10.1007/s13410-022-01143-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 11/01/2022] [Indexed: 12/23/2022] Open
Abstract
Hypertension and diabetes mellitus (DM) are two of the leading lifestyle diseases in the Indian and South Asian populations that often co-exist due to overlapping pathophysiological factors. Obesity, insulin resistance, inflammation, and oxidative stress are thought to be some common pathways. Up to 50% of hypertensive cases in India are diagnosed with type 2 diabetes mellitus (T2DM), which defines the need for a comprehensive guideline for managing hypertension in diabetic patients. These RSSDI guidelines have been formulated based on consultation with expert endocrinologists in India and Southeast Asia, acknowledging the needs of the Indian population. Ambulatory blood pressure monitoring and office and home-based blood pressure (BP) monitoring are recommended for the early analysis of risks. Cardiovascular risks, end-organ damage, and renal disorders are the primary complications associated with diabetic hypertension that needs to be managed with the help of non-pharmacological and pharmacological interventions. The non-pharmacological interventions include the nutrition education of the patient to reduce the intake of salt, sodium, and trans fats and increase the consumption of nuts, fresh fruits, vegetables, and potassium-rich foods. It is also recommended to initiate 50 to 60 min of exercise three to four times a week since physical activity has shown to be more beneficial for hypertension control in Indian patients than dietary modulation. For the pharmacological management of hypertension in patients with T2DM, angiotensin II receptor blockers (ARBs) are recommended as the first line of therapy, demonstrating their superiority over other antihypertensive agents such as ACEi. However, most of the global hypertension guidelines recommend initiation with combination therapy to achieve better BP control in most patients and to reduce the risk of adverse events. For combination therapy, calcium channel blockers (CCBs) are recommended to be administered along with ARBs instead of beta-blockers or diuretics to avoid the risk of cardiovascular events and hyperglycaemia. Among the CCBs, novel molecules (e.g. cilnidipine) are recommended in combination with ARBs for better cardiovascular and reno-protection in diabetic hypertensive patients.

Cilnidipine and magnesium sulfate supplement ameliorates hyperglycemia, dyslipidemia and inhibits oxidative-stress in fructose-induced diabetic rats. Heliyon 2022; 8:e08671. [PMID: 35028456 PMCID: PMC8741449 DOI: 10.1016/j.heliyon.2021.e08671] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 07/23/2021] [Accepted: 12/21/2021] [Indexed: 11/18/2022] Open
Abstract
The study was designed to evaluate the safety and efficacy of cilnidipine (CLN) and Mg-supplementation in fructose-induced diabetic rats. Diabetes was induced into male Wister rats by feeding fructose (10% solution) in drinking water for 8 weeks. Diabetic rats were subjected for the oral administration of CLN1 (1 mg/kg/day) and CLN10 (10 mg/kg/day), and/or methyl cellulose (0.5%) as vehicle for 28 days. After 14 days of CLN treatment, MgSO4 (1%) was added to CLN1 and CLN10 groups for another 14 days. Age-matched healthy rats were used as normal control. After 28 days body weights were measured and organ weight to body ratio was calculated. Serum samples were analysed for fasting blood sugar (FBS), glycosylated hemoglobin (HbA1c), uric acid, lipid profiles, tri-iodothyronine (T3) and thyroid stimulating hormone (TSH), serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), creatine phosphokinase myocardial-band (CK-MB), creatinine, albumin, electrolytes. Oral glucose tolerance tests (OGTT), liver histopathology and in-vivo antioxidant activities were also performed. The survival rate in diabetic rats was 100% after the oral administration of CLN, Mg-supplement and/or vehicle. A significant reduction in FBS levels and improvement in OGTT were observed in CLN10, CLN1+Mg and CLN10 + Mg groups after 28 days. Further, the treatment ameliorated serum lipid profile, uric acid, and albumin levels. The groups CLN10 and CLN10 + Mg improved HbA1c, liver glycogen, creatinine, T3, TSH levels and electrolytes in diabetic rats. Moreover, liver from CLN10 and CLN10 + Mg groups showed preservation of cellular architecture as evidenced by attenuation of inflammatory markers SGPT, SGOT and CK-MB; and the levels of superoxide dismutase (SOD), catalase (CAT), glutathione, malondialdehyde (MDA), markers of oxidative stress were significantly improved. CLN exerted prominent effects in the amelioration of hyperglycemia, dyslipidemia and reduced hepatic inflammation; and Mg-supplementation might have some beneficial effects on diabetic complications and oxidative stress in fructose-induced diabetic rats.
