| Description |
NTU281 is a potent transglutaminase-2 inhibitor. NTU281 can reduce the increases in serum creatinine and albuminuria in diabetic rats. NTU281 can also reduce glomerular collagen I accumulation, Hic-5 and α-SMA expression, and apoptosis. NTU281 can be used for researching glomerulosclerosis caused by diabetes[1][2].

NTU281 (2.5 μl/h of 50 mM; cannulate to deliver into kidneys) reduces glomerular collagen I overexpression as well as the increases in glomerular Hic-5 and α-SMA expression; also decreases serum creatinine, albuminuria, glomerulosclerosis and tubulointerstitial scarring in diabetic rats[1][2]. Animal Model: Male Wistar Han rats [subjected to right uninephrectomy, then induced hyperglycemia by tail vein injection of streptozotocin (35 mg/kg in citrate buffer pH 4)][1] Dosage: 2.5 μl/h of 50 mM Administration: Cannulated to deliver into kidneys Result: Reduced glomerular collagen I overexpression by ~50%; reduced the increases in glomerular Hic-5 expression; reduced diabetic nephropathy-induced α-SMA expression. Animal Model: Male Wistar Han rats [subjected to right uninephrectomy, then induced hyperglycemia by tail vein injection of streptozotocin (35 mg/kg in citrate buffer pH 4)][2] Dosage: Various concentration Administration: Cannulated to deliver into kidneys Result: Significantly reduced the increases in serum creatinine (-68%) and albuminuria (-80%) in diabetic rats during eight-month experimental period; reduced in glomerulosclerosis (-76.6%) and tubulointerstitial scarring (-68.2%) as a result of lowered accumulation of collagen I, III and IV; and reduced numbers of myofibroblasts present.
