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. -
Treatment of Diabetes Mellitus
TREATMENT OF DIABETES MELLITUS DIABETES is a condition that affects how the body makes energy from food. Food is broken down into sugar (glucose) in the body and released into the blood. When the blood sugar level rises after a meal, insulin responds to let the sugar into the cells to be used as energy. In diabetes, the body either does not make enough insulin or it stops responding to insulin as well as it should. This results in sugar staying in the blood and leads to serious health problems over time. DIAGNOSIS OF DIABETES1 • A1C Test: Lab test measuring average blood sugar over past two to three months • Fasting Blood Sugar Test: Lab test measuring blood sugar after eight hours of no food or drink • Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and two hours after drinking a specific sugary liquid • Random Blood Sugar Test: Measures blood sugar at a moment in time, without any kind of preparation (like fasting) FASTING BLOOD ORAL GLUCOSE TOLERANCE RANDOM BLOOD RESULT A1C TEST SUGAR TEST TEST SUGAR TEST Diabetes ≥ 6.5% ≥126 mg/dL ≥ 200 mg/dL ≥ 200 mg/dL Prediabetes 5.7 – 6.4% 100 – 125 mg/dL 140 – 199 mg/dL N/A Normal < 5.7% ≤99 mg/dL < 140 mg/dL N/A NON-DRUG TREATMENTS2 THERAPY COST WHAT TO EXPECT Diet (Mediterranean diet) and exercise (30 minutes a day, five days a week of moderate- Weight loss $-$$ intensity exercise); 7% weight loss decreases risk of diabetes3 Psychological intervention $$-$$$ Psychotherapy may reduce diabetic distress and improve glycemic control4,5 nationalcooperativerx.com PRESCRIPTION TREATMENTS -

Pharmacia 67(4): 363–371. https://doi.org/10.3897/pharmacia.67.e58392 Abstract Palmatine a protoberberine alkaloid has been previously reported to possess in vivo antidiabetic and antioxidant property. The aim of the experiment is to evaluate the in vitro antidiabetic activity and in-silico studies of the binding energies of Palmatine, acarbose, and Sitagliptin with the three enzymes of alpha-amylase, alpha-glucosidase, and dipeptidyl peptidase-IV (DPP-IV). The in vitro antidiabetic study was done by evaluating the inhibitory effect of palmatine on the activities of alpha-amylase, alpha-glucosidase, and DPP-IV. Acarbose, and sitagliptin was used as standard drug. The molecular docking study was performed to study the binding interactions of palmatine with alpha-glucosidase, a-amylase, and DPP-IV. The binding interactions were compared with the standard compounds Sitagliptin and acarbose. Palmatine with IC50 (1.31 ± 0.27 µM) showed significant difference of (< 0.0001) higher inhib- iting effect on alpha-amylase and weak inhibiting effect on alpha-glucosidase enzyme with IC50 (9.39 ± 0.27 µM) and DPP-IV with IC50 (8.7 ± 1.82 µM). -

Valsartan in Combination with Metformin and Gliclazide in Diabetic
Patra et al. Future Journal of Pharmaceutical Sciences (2021) 7:157 Future Journal of https://doi.org/10.1186/s43094-021-00307-2 Pharmaceutical Sciences RESEARCH Open Access Valsartan in combination with metformin and gliclazide in diabetic rat model using developed RP-HPLC method Rasmita Patra, Yedukondalu Kollati, Sampath Kumar NS and Vijaya R. Dirisala* Abstract Background: Oral administration of biguanides (metformin) and sulfonylureas (gliclazide) are the most common approach of management of type 2 diabetes in humans. Among these diabetic patients, approximately 40–60% suffers from hypertension. Hence, the need of the day is application of polytherapy. A major challenge in polytherapy is the drug-drug interactions that may arise. Hence, this study is focused to develop a reverse phase high-performance liquid chromatography (RP-HPLC) method for concurrent estimation of diabetic drug metformin and hypertension drug valsartan using C18 column and find any possible pharmacokinetic interactions between the two drug combinations strategies, i.e., metformin-valsartan and gliclazide-valsartan in streptozotocin-induced diabetic rats. Result: The bioanalysis of drug-drug interaction pharmacokinetic result showed no significant difference in the tmax of single treatment of gliclazide and single treatment of metformin or upon co-administration with valsartan. Conclusion: Our study has shown that polytherapy of valsartan, a drug administered for hypertension along with hypoglycemic drugs metformin and gliclazide, can be advantageous and safe in patients suffering from both diabetes and hypertension.
