Molecular Basis of Blood Glucose Regulation Asma Ahmed and Noman Khalique
Chapter Molecular Basis of Blood Glucose Regulation Asma Ahmed and Noman Khalique Abstract Blood glucose level is regulated by multiple pancreatic hormones, which regulate it by different pathways in normal and abnormal conditions by expressing or suppressing multiple genes or molecular or cellular targets. Multiple synthetic drugs and therapies are used to cure glucose regulatory problems, while many of them are used to cure other health issues, which arise due to disturbance in blood glucose regulations. Many new approaches are used for the development of phytochemical- based drugs to cure blood glucose regulation problems, and many of the compounds have been isolated and identified to cure insulin resistance or regulate beta cell function or glucose absorption in the guts or GLP-1 homoeostasis or two/more pathways (e.g., either cure hyperglycemia or raise insulin resistance or cure pan- creatic beta cell regeneration or augmentation of GLP-1, production of islet cell, production and increased insulin receptor signaling and insulin secretion or decreased insulin tolerance or gluconeogenesis and insulin-mimetic action or pro- duction of α-glucosidase and α-amylase inhibitor or conserve islet mass or activate protein kinase A (PKA) and extracellular signal regulated kinases (ERK) or activate AMPK and reduce insulin sensitivity or suppress α-glucosidase activity and activate AMPK and downstream molecules or prevents cell death of pancreatic β-cell and activates SIRT1 or lower blood glucose due to their insulin-like chemical structures or decrease lipid peroxidation. Keywords: genes, molecular and cellular targets, hormones, pathways 1. Introduction Blood glucose is regulated by the pancreatic hormones alone or in combination with other endocrine glands and all this is controlled by one or more gene or cellular or molecular targets. -
LANTUS® (Insulin Glargine [Rdna Origin] Injection)
Rev. March 2007 Rx Only LANTUS® (insulin glargine [rDNA origin] injection) LANTUS® must NOT be diluted or mixed with any other insulin or solution. DESCRIPTION LANTUS® (insulin glargine [rDNA origin] injection) is a sterile solution of insulin glargine for use as an injection. Insulin glargine is a recombinant human insulin analog that is a long-acting (up to 24-hour duration of action), parenteral blood-glucose-lowering agent. (See CLINICAL PHARMACOLOGY). LANTUS is produced by recombinant DNA technology utilizing a non- pathogenic laboratory strain of Escherichia coli (K12) as the production organism. Insulin glargine differs from human insulin in that the amino acid asparagine at position A21 is replaced by glycine and two arginines are added to the C-terminus of the B-chain. Chemically, it is 21A- B B Gly-30 a-L-Arg-30 b-L-Arg-human insulin and has the empirical formula C267H404N72O78S6 and a molecular weight of 6063. It has the following structural formula: LANTUS consists of insulin glargine dissolved in a clear aqueous fluid. Each milliliter of LANTUS (insulin glargine injection) contains 100 IU (3.6378 mg) insulin glargine. Inactive ingredients for the 10 mL vial are 30 mcg zinc, 2.7 mg m-cresol, 20 mg glycerol 85%, 20 mcg polysorbate 20, and water for injection. Inactive ingredients for the 3 mL cartridge are 30 mcg zinc, 2.7 mg m-cresol, 20 mg glycerol 85%, and water for injection. The pH is adjusted by addition of aqueous solutions of hydrochloric acid and sodium hydroxide. LANTUS has a pH of approximately 4. CLINICAL PHARMACOLOGY Mechanism of Action: The primary activity of insulin, including insulin glargine, is regulation of glucose metabolism. -

Department of Biochemistry and Molecular Medicine, University of California Davis, Davis, California, United States of America ABSTRACT: The Type 2 Diabetes Mellitus (T2DM) epidemic undoubtedly creates a need for the development of new phar- maceuticals. With the goal of generating new therapeutics for this disease, computational studies were conducted to design novel dipeptidyl peptidase-4 (DPP-4) inhibitors. Two candidates, generated by chemical intuition-driven design and bioiso- steric replacement, were found to have better docking scores than anagliptin, a currently available diabetes medication.

A recent Type 2 Diabetes Mellitus (T2DM) is dubbed the meta-analysis seems to suggest a possible increased pan- “epidemic of the 21st century”— affecting millions of pa- creatitis risk for sitagliptin -

200 Adverse Drug Reactions in a Southern Hospital in Taiwan 201
200 Adverse Drug Reactions in a southern hospital in Taiwan Yuhong Lin1 1Kaohsiung Veterans General Hospital Tainan Branch, Tainan City, Taiwan Objective: The aim of this study was to evaluate the adverse drug reactions (ADRs) reporting in a southern hospital in Taiwan. Methods: It was a retrospective study of ADRs reporting in 2016. We analysed ADRs which contain gender and age, occurring sources, Anatomical Therapeutic Chemical (ATC) classification of suspected drugs, management of ADRs and so on. Results: The study collected eighty-nine ADRs reported. Most of ADRs reported were occurring in outpatient department (87.6%). The average age of ADRs reported was 67.6 years. Majority of all ADRs reported were females (55.1%). According to ATC classification system, the major classification of suspected drugs were Sensory organs (32.6%). Among the adverse reactions, Dermatologic Effects (37.1%) were the major type of ADRs. Also, the major management of ADRs was to stop using the current suspected drug (46.1%). Conclusion: Certainly, ADRs reporting are still a very important information to healthcare professionals. As a result, we put all information of ADRs reported into medical system in our hospital and it will improve the safety of medication use. In case of prescribe the suspected medicines, it can remind doctor to think of information about patient's ADRs reported. No drugs is administered without risk. Therefore, all healthcare professionals should have a responsibility to their patients, who themselves are becoming more aware of problems -
Effects of Exenatide on Cardiac Function, Perfusion, and Energetics
Chen et al. Cardiovasc Diabetol (2017) 16:67 DOI 10.1186/s12933-017-0549-z Cardiovascular Diabetology ORIGINAL INVESTIGATION Open Access Efects of exenatide on cardiac function, perfusion, and energetics in type 2 diabetic patients with cardiomyopathy: a randomized controlled trial against insulin glargine Weena J. Y. Chen1*, Michaela Diamant1^, Karin de Boer2, Hendrik J. Harms3, Lourens F. H. J. Robbers2, Albert C. van Rossum2, Mark H. H. Kramer1, Adriaan A. Lammertsma3 and Paul Knaapen2 Abstract Background: Multiple bloodglucose-lowering agents have been linked to cardiovascular events. Preliminary studies showed improvement in left ventricular (LV) function during glucagon-like peptide-1 receptor agonist administration. Underlying mechanisms, however, are unclear. The purpose of this study was to investigate myocardial perfusion and oxidative metabolism in type 2 diabetic (T2DM) patients with LV systolic dysfunction as compared to healthy controls. Furthermore, efects of 26-weeks of exenatide versus insulin glargine administration on cardiac function, perfusion and oxidative metabolism in T2DM patients with LV dysfunction were explored. Methods and results: Twenty-six T2DM patients with LV systolic dysfunction (cardiac magnetic resonance (CMR) derived LV ejection fraction (LVEF) of 47 13%) and 10 controls (LVEF of 59 4%, P < 0.01 as compared to patients) were analyzed. Both myocardial perfusion± during adenosine-induced hyperemia± (P < 0.01), and coronary fow reserve 15 (P < 0.01), measured by [ O]H2O positron emission tomography (PET), were impaired in T2DM patients as compared to healthy controls. Myocardial oxygen consumption and myocardial efciency, measured using [11C]acetate PET and CMR derived stroke volume, were not diferent between the groups. -
