Sodium-Glucose Cotransporter Inhibitors as Antidiabetic Drugs: Current Development and Future Perspectives

Sodium-glucose cotransporter 2 (SGLT-2) inhibitors (gliflozins) represent the most recently approved class of oral antidiabetic drugs. SGLT-2 overexpression in diabetic patients contributes significantly to hyperglycemia and related complications. Therefore, SGLT-2 became a highly interesting therapeutic target, culminating in the approval for clinical use of dapagliflozin and analogues in the past decade. Gliflozins improve glycemic control through a novel insulin-independent mechanism of action and, moreover, exhibit significant cardiorenal protective effects in both diabetic and nondiabetic subjects. Therefore, gliflozins have received increasing attention, prompting extensive structure-activity relationship studies and optimization approaches. The discovery that intestinal SGLT-1 inhibition can provide a novel opportunity to control hyperglycemia, through a multifactorial mechanism, recently encouraged the design of low adsorbable inhibitors selectively directed to the intestinal SGLT-1 subtype as well as of dual SGLT-1/SGLT-2 inhibitors, representing a compelling strategy to identify new antidiabetic drug candidates.

Efficient Route to Canagliflozin via Anhydroketopyranose

The development of an efficient route for the synthesis of Canagliflozin is reported. The anhydroketopyranose intermediate was isolated as a novel intermediate, which was used to prepare Canagliflozin API in high purity.

Structural Perspectives and Advancement of SGLT2 Inhibitors for the Treatment of Type 2 Diabetes

Diabetes mellitus is an ailment that affects a large number of individuals worldwide and its pervasiveness has been predicted to increase later on. Every year, billions of dollars are spent globally on diabetes-related health care practices. Contemporary hyperglycemic therapies to rationalize Type 2 Diabetes Mellitus (T2DM) mostly involve pathways that are insulin-dependent and lack effectiveness as the pancreas' β-cell function declines more significantly. Homeostasis via kidneys emerges as a new and future strategy to minimize T2DM complications. This article covers the reabsorption of glucose mechanism in the kidneys, the functional mechanism of various Sodium- Glucose Cotransporter 2 (SGLT2) inhibitors, their structure and driving profile, and a few SGLT2 inhibitors now accessible in the market as well as those in different periods of advancement. The advantages of SGLT2 inhibitors are dose-dependent glycemic regulation changes with a significant reduction both in the concentration of HbA1c and body weight clinically and statistically. A considerable number of SGLT2 inhibitors have been approved by the FDA, while a few others, still in preliminaries, have shown interesting effects.

Biological and Pharmacological Effects of Synthetic Saponins

Saponins are amphiphilic molecules consisting of carbohydrate and either triterpenoid or steroid aglycone moieties and are noted for their multiple biological activities-Fungicidal, antimicrobial, antiviral, anti-inflammatory, anticancer, antioxidant and immunomodulatory effects have all been observed. Saponins from natural sources have long been used in herbal and traditional medicines; however, the isolation of complexed saponins from nature is difficult and laborious, due to the scarce amount and structure heterogeneity. Chemical synthesis is considered a powerful tool to expand the structural diversity of saponin, leading to the discovery of promising compounds. This review focuses on recent developments in the structure optimization and biological evaluation of synthetic triterpenoid and steroid saponin derivatives. By summarizing the structure-activity relationship (SAR) results, we hope to provide the direction for future development of saponin-based bioactive compounds.

An exhaustive perspective on structural insights of SGLT2 inhibitors: A novel class of antidiabetic agent

Diabetes mellitus is the global health issue and become an alarming threat in the modern era where human lifestyle gets compromised with modernization. According to the latest statistical report 2020, USA has 9.47% (31 million among 32.72 cr), China has 8.3% (116.4 million among 139.27 cr) and India has 5.6% (77 million among 135.26 cr) of the diabetic people, indicating that diabetes is more prevailing in developed countries as compared to the developing countries. The number of diabetic patients is rising day by day at a tremendous rate and soon it may affect each and every person in a family. So, there is an urgent need to develop novel entities that can meet the scarcity of present antidiabetic agents. In the last few decades, the sodium-glucose co-transporter 2 (SGLT2) has emerged as a prominent target for the treatment of Type 2 diabetes mellitus due to its novel mechanism of action & no involvement in insulin signaling pathway. Most of the inhibitors that target SGLT2 contain three basic moieties: glucose, two benzene rings (one is connected with glucose and the other with methylene), and the methylene bridge which are similar to dapagliflozin. Several SGLT2 inhibitors and their derivatives such as remogliflozin etabonate (phase-II), sotagliflozin (phase-III) and bexagliflozin (phase-III) are under different phases of clinical trial studies and some have been patented. The present review is focused on SGLT2 inhibitors, structure activity relationships (SARs) of dapagliflozin and its several analogues for their binding affinity with SGLT2. We have also presented and summarized the efforts made by various researchers in terms of the synthesis of various dapagliflozin derivatives till date.
