Summary
Sodium glucose cotransporters (SGLTs) use sodium ions to move glucose. New research reveals how SGLT inhibitors bind to and block these transporters at the atomic level, aiding diabetes treatment.
Area of Science:
- Biochemistry
- Structural Biology
- Pharmacology
Background:
- Sodium glucose cotransporters (SGLTs) are crucial for glucose reabsorption.
- SGLT inhibitors are established treatments for diabetes mellitus.
- Understanding inhibitor-transporter interactions is key for drug development.
Purpose of the Study:
- To elucidate the atomic-level mechanisms of SGLT inhibition.
- To characterize the binding modes of diverse SGLT inhibitors.
- To provide structural insights into transporter function.
Main Methods:
- X-ray crystallography
- Cryo-electron microscopy
- Structure-based drug design
Main Results:
- Detailed atomic structures of SGLTs bound to various inhibitors were determined.
- Key interactions governing inhibitor binding and transporter inhibition were identified.
- Structure-activity relationships for different chemical classes of inhibitors were established.
Conclusions:

22.6K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:26Glucose Absorption Into the Small Intestine
31.6K
Complex carbohydrates consumed cannot be absorbed into the small intestine in their original form. First, they must be hydrolyzed to a monosaccharide form such as glucose or galactose. These monosaccharides are then transported across the intestinal membrane and into the blood via transcellular transport. The intestinal epithelial cells allow the movement of these monosaccharides with a defined 'entry' through membrane transporter proteins present on their apical membrane and...

01:32Secondary Active Transport
7.0K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme "pump" embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

181
Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...

01:44The Significance of Membrane Transport
25.2K
The transport of solutes across the cell membrane is essential for metabolic processes, like maintaining cell size and volume, generating the action potential, exchanging nutrients and gases, etc. Membrane transport can be either passive or active. It can be simple diffusion, facilitated, or mediated transport aided by transport proteins such as transporters and channels.
Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...

01:19Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
170
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
