Abstract
Sodium-glucose co-transporter (SGLT) inhibitors offer a novel tool to control hyperglycemia and its complications. We present preliminary findings of pantoyltaurine, N-substituted analog of taurine, as diuretic, glucosuric and natriuretic agent in streptozotocin (60 mg/kg/mL, i.p.)-induced type 1 diabetic Sprague-Dawley rats and whether pantoyltaurine has an effect on regulation of SGLT isoforms that may further help in reducing hyperglycemia and improving renal function. After 14 days of persistent diabetes, phlorizin (0.4 g/kg/day, s.c.) or pantoyltaurine (2.4 mM/kg/day, p.o.) was administered for three weeks, days 15 - 35. As expected, diabetic rats showed persistent hyperglycemia, hyperphagia and weight loss. Pantoyltaurine and phlorizin-treated diabetic rats consumed less diet, showed significant weight loss, reduced persistent hyperglycemia as well as reduced glucose load after oral glucose tolerance test. Diuretic, glucosuric and natriuretic response of diabetic rats was enhanced by pantoyltaurine independent of renal and plasma oxidative stress, plasma insulin and renal expression of SGLT-2. Phlorizin and pantoyltaurine reduced renal expression of SGLT-1, which accounts for ≤ 10% of glucose reabsorption. However, pantoyltaurine, but not phlorizin, normalized elevated fractional excretion of urea nitrogen and clearance of blood urea nitrogen in diabetic rats, suggesting lessening effect of pantoyltaurine on uremic toxicity associated with diabetes. Collectively, our preliminary findings show that chronic treatment with pantoyltaurine may help in an insulin-independent manner to lower diabetic hyperglycemia by producing diuresis, glucosuria and natriuresis that may have translated in improvement of renal function.
