  • Dualism of Peroxisome Proliferator-Activated Receptor Α/Γ: a Potent Clincher in Insulin Resistance
    AEGAEUM JOURNAL ISSN NO: 0776-3808 Dualism of Peroxisome Proliferator-Activated Receptor α/γ: A Potent Clincher in Insulin Resistance Mr. Ravikumar R. Thakar1 and Dr. Nilesh J. Patel1* 1Faculty of Pharmacy, Shree S. K. Patel College of Pharmaceutical Education & Research, Ganpat University, Gujarat, India. [email protected] Abstract: Diabetes mellitus is clinical syndrome which is signalised by augmenting level of sugar in blood stream, which produced through lacking of insulin level and defective insulin activity or both. As per worldwide epidemiology data suggested that the numbers of people with T2DM living in developing countries is increasing with 80% of people with T2DM. Peroxisome proliferator-activated receptors are a family of ligand-activated transcription factors; modulate the expression of many genes. PPARs have three isoforms namely PPARα, PPARβ/δ and PPARγ that play a central role in regulating glucose, lipid and cholesterol metabolism where imbalance can lead to obesity, T2DM and CV ailments. It have pathogenic role in diabetes. PPARα is regulates the metabolism of lipids, carbohydrates, and amino acids, activated by ligands such as polyunsaturated fatty acids, and drugs used as Lipid lowering agents. PPAR β/δ could envision as a therapeutic option for the correction of diabetes and a variety of inflammatory conditions. PPARγ is well categorized, an element of the PPARs, also pharmacological effective as an insulin resistance lowering agents, are used as a remedy for insulin resistance integrated with type- 2 diabetes mellitus. There are mechanistic role of PPARα, PPARβ/δ and PPARγ in diabetes mellitus and insulin resistance. From mechanistic way, it revealed that dual PPAR-α/γ agonist play important role in regulating both lipids as well as glycemic levels with essential safety issues.

Received: 22 June 2018; Accepted: 24 July 2018; Published: 27 July 2018 Abstract: Peroxisome proliferator-activated receptors (PPARs) are a well-known pharmacological target for the treatment of multiple diseases, including diabetes mellitus, dyslipidemia, cardiovascular diseases and even primary biliary cholangitis, gout, cancer, Alzheimer’s disease and ulcerative colitis. The three PPAR isoforms (α, β/δ and γ) have emerged as integrators of glucose and lipid metabolic signaling networks. Typically, PPARα is activated by fibrates, which are commonly used therapeutic agents in the treatment of dyslipidemia. The pharmacological activators of PPARγ include thiazolidinediones (TZDs), which are insulin sensitizers used in the treatment of type 2 diabetes mellitus (T2DM), despite some drawbacks. In this review, we summarize 84 types of PPAR synthetic ligands introduced to date for the treatment of metabolic and other diseases and provide a comprehensive analysis of the current applications and problems of these ligands in clinical drug discovery and development.

  • Structural Basis for the Enhanced Anti-Diabetic Efficacy Of
    www.nature.com/scientificreports OPEN Structural Basis for the Enhanced Anti-Diabetic Efcacy of Lobeglitazone on PPARγ Received: 9 October 2017 Jun Young Jang 1, Hwan Bae2, Yong Jae Lee3, Young Il Choi3, Hyun-Jung Kim4, Accepted: 4 December 2017 Seung Bum Park 2, Se Won Suh2, Sang Wan Kim 5 & Byung Woo Han 1 Published: xx xx xxxx Peroxisome proliferator-activated receptor γ (PPARγ) is a member of the nuclear receptor superfamily. It functions as a ligand-activated transcription factor and plays important roles in the regulation of adipocyte diferentiation, insulin resistance, and infammation. Here, we report the crystal structures of PPARγ in complex with lobeglitazone, a novel PPARγ agonist, and with rosiglitazone for comparison. The thiazolidinedione (TZD) moiety of lobeglitazone occupies the canonical ligand-binding pocket near the activation function-2 (AF-2) helix (i.e., helix H12) in ligand-binding domain as the TZD moiety of rosiglitazone does. However, the elongated p-methoxyphenol moiety of lobeglitazone interacts with the hydrophobic pocket near the alternate binding site of PPARγ. The extended interaction of lobeglitazone with the hydrophobic pocket enhances its binding afnity and could afect the cyclin- dependent kinase 5 (Cdk5)-mediated phosphorylation of PPARγ at Ser245 (in PPARγ1 numbering; Ser273 in PPARγ2 numbering). Lobeglitazone inhibited the phosphorylation of PPARγ at Ser245 in a dose-dependent manner and exhibited a better inhibitory efect on Ser245 phosphorylation than rosiglitazone did. Our study provides new structural insights into the PPARγ regulation by TZD drugs and could be useful for the discovery of new PPARγ ligands as an anti-diabetic drug, minimizing known side efects.

Received: 30 September 2019; Accepted: 10 October 2019; Published: 11 October 2019 Abstract: Peroxisome proliferator-activated receptors (PPARs) are nuclear receptors that govern the expression of genes responsible for energy metabolism, cellular development, and differentiation. Their crucial biological roles dictate the significance of PPAR-targeting synthetic ligands in medical research and drug discovery. Clinical implications of PPAR agonists span across a wide range of health conditions, including metabolic diseases, chronic inflammatory diseases, infections, autoimmune diseases, neurological and psychiatric disorders, and malignancies. In this review we aim to consolidate existing clinical evidence of PPAR modulators, highlighting their clinical prospects and challenges. Findings from clinical trials revealed that different agonists of the same PPAR subtype could present different safety profiles and clinical outcomes in a disease-dependent manner.
