SLC38A6 Inhibitors
Chemical inhibitors of SLC38A6 include a variety of compounds that interfere with its function by different mechanisms. Tetrodotoxin is a potent neurotoxin known to block voltage-gated sodium channels; this action can reduce the sodium gradient necessary for SLC38A6 to transport amino acids, thereby inhibiting its activity. Similarly, ouabain and digoxin target the Na+/K+-ATPase pump, crucial for maintaining the sodium and potassium gradient across the plasma membrane. Inhibition of this pump by these compounds disrupts the sodium gradient, a driving force for the function of SLC38A6, leading to its functional inhibition. Concanavalin A, a lectin, can bind to glycoproteins on the cell surface, which could include the glycosylated regions of SLC38A6, potentially causing steric hindrance or conformational changes that impede the transporter's function.
Other inhibitors such as phlorizin compete with the natural substrates of SLC38A6, which in this case are amino acids, thereby reducing the transporter's ability to carry its cargo across the cell membrane. Amiloride and its analog benzamil, while known to inhibit sodium-proton exchangers and epithelial sodium channels respectively, can also indirectly affect SLC38A6 by altering the intracellular proton and sodium gradients. Verapamil, a calcium channel blocker, can impact cellular signaling and processes that may indirectly affect SLC38A6 function. Niflumic acid, although a chloride channel blocker, can disrupt cellular ion homeostasis and, as a result, indirectly modulate the function of SLC38A6. Lastly, diuretics like triamterene, known for inhibiting renal epithelial sodium channels, can indirectly diminish the sodium gradient, which is harnessed by SLC38A6 for amino acid transport, leading to the inhibition of its transport activity.

Concanavalin A | 11028-71-0 | sc-203007 sc-203007A sc-203007B | 50 mg 250 mg 1 g | $119.00 $364.00 $947.00 | 17 | |
Concanavalin A is a lectin that can bind to glycoproteins on the cell surface. Since SLC38A6 is a membrane transporter, it is postulated to have glycosylated extracellular regions. Binding of concanavalin A to these regions could sterically hinder the transporter's function or induce conformational changes that inhibit SLC38A6's ability to transport amino acids. | ||||||
Phloridzin dihydrate | 7061-54-3 | sc-215708 sc-215708A | 250 mg 1 g | $49.00 $119.00 | ||
Phlorizin is a competitive inhibitor of SLC family transporters, particularly those involved in glucose transport. While its primary action is on glucose transporters, phlorizin can also inhibit SLC38A6 by competing with the substrates of this amino acid transporter, thereby reducing its ability to transport amino acids across the cell membrane. | ||||||
Amiloride | 2609-46-3 | sc-337527 | 1 g | $296.00 | 7 | |
Amiloride is known to inhibit sodium-proton exchangers. Although not a direct inhibitor of SLC38A6, amiloride can reduce intracellular proton gradients, which are necessary for the optimal function of many sodium-coupled transporters, including SLC38A6. By altering the electrochemical gradient, amiloride can indirectly inhibit the function of SLC38A6. | ||||||
Ouabain-d3 (Major) | sc-478417 | 1 mg | $516.00 | |||
Ouabain is a specific inhibitor of the Na+/K+-ATPase pump, which maintains the sodium and potassium gradient across the plasma membrane. By inhibiting this pump, ouabain disrupts the sodium gradient necessary for sodium-coupled transporters such as SLC38A6, leading to its functional inhibition as the sodium gradient is crucial for its activity. | ||||||
12β-Hydroxydigitoxin | 20830-75-5 | sc-213604 sc-213604A | 1 g 5 g | $143.00 $694.00 | ||
12β-Hydroxydigitoxin, like ouabain, targets and inhibits the Na+/K+-ATPase pump. This action leads to a decrease in the sodium gradient, which is used by SLC38A6 to cotransport amino acids into cells. The inhibition of this pump by digoxin would thus functionally inhibit the transport activity of SLC38A6. | ||||||
Verapamil | 52-53-9 | sc-507373 | 1 g | $374.00 | ||
Verapamil is a calcium channel blocker that can indirectly influence sodium-coupled transporters. By blocking calcium channels, verapamil can affect cellular signaling pathways and intracellular processes that may rely on calcium signaling, which could indirectly inhibit the function of SLC38A6 by altering the cellular environment in which it operates. | ||||||
Niflumic acid | 4394-00-7 | sc-204820 | 5 g | $32.00 | 3 | |
Niflumic acid is a nonsteroidal anti-inflammatory drug known to block chloride channels. Though primarily affecting chloride channels, it can also influence other ion gradients and cellular ion homeostasis. Changes in chloride ion concentration can affect the sodium gradient due to coupled ion transport systems, which may indirectly inhibit SLC38A6 function. | ||||||
Benzamil•HCl | 161804-20-2 | sc-201070 | 50 mg | $195.00 | 1 | |
Benzamil is an amiloride analog that selectively inhibits epithelial sodium channels. While it primarily targets these channels, by reducing sodium influx, it can indirectly affect sodium-dependent transporters like SLC38A6. The inhibition of sodium channels by benzamil can alter the sodium gradient, which is necessary for SLC38A6 to transport amino acids, thus functionally inhibiting it. | ||||||
Triamterene | 396-01-0 | sc-213103A sc-213103 | 1 g 5 g | $22.00 $54.00 | ||
Triamterene is another diuretic that inhibits renal epithelial sodium channels. By inhibiting these channels, triamterene can lead to a decrease in the sodium gradient, which is utilized by SLC38A6 for amino acid transport. The indirect inhibition of the sodium gradient by triamterene can thus lead to functional inhibition of SLC38A6. | ||||||
