ARI-809

(Synonyms: CP-744809)

ARI-809 (CP-744809) is a highly selective, orally active aldose reductase inhibitor with an IC₅₀ of 1 nM. ARI-809 blocks excessive glucose flux through the polyol pathway. ARI-809 normalizes elevated sorbitol and fructose levels in sciatic nerve tissues of diabetic rat models, inhibits sorbitol accumulation in lens tissues, and brings elevated urinary albumin excretion close to normal. ARI-809 can be used in diabetes research.

Biological Activity

Description

In Vitro

ARI-809 (CP-744809) shows high selectivity for aldose reductase over related dehydrogenases, with the lowest off-target potency against aldehyde reductase (IC₅₀ = 930 nM) and minimal activity against alcohol, fructose, and sorbitol dehydrogenases^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Rat^[1]	2 mg/kg	p.o.	98 %	5 μg/mL	26 h

In Vivo

ARI-809 (0.2-4.0 mg/kg; oral gavage; single doses at 4,7,24h post-streptozotocin '; once daily for 5 days (chronic)) potently normalizes elevated polyol pathway metabolites in diabetic rat sciatic nerve and lens tissues, with ED₅₀ values of 0.2 mg/kg and 0.8 mg/kg for sorbitol and fructose normalization in the acute test, and ED₉₀ values of 0.8 mg/kg and 4.0 mg/kg for sorbitol and fructose normalization in the chronic test, while also reducing urinary albumin output in diabetic rats^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

CD Sprague Dawley (male, 175-225 g, streptozotocin-induced)^[1]
Dosage:

0.2 mg/kg (acute sciatic nerve sorbitol normalization); 0.8 mg/kg (acute sciatic nerve fructose normalization; chronic sciatic nerve sorbitol normalization); 4.0 mg/kg (chronic sciatic nerve fructose normalization)
Administration:

oral gavage; single doses at 4,7,24h post-streptozotocin (acute); once daily for 5 days (chronic)
Result:

Achieved an ED₅₀ of 0.2 mg/kg for normalization of elevated sciatic nerve sorbitol levels in acute test.
Achieved an ED₅₀ of 0.8 mg/kg for normalization of elevated sciatic nerve fructose levels in acute test.
Achieved an ED₉₀ of 0.8 mg/kg for normalization of elevated sciatic nerve sorbitol levels in chronic test.
Achieved an ED₉₀ of 4.0 mg/kg for normalization of elevated sciatic nerve fructose levels in chronic test.
Potently suppressed elevated lens sorbitol levels, with greater efficacy than comparator agents including zopolrestat.
Produced near-normalization of 2.5-fold elevated urinary albumin output in a diabetic rat model.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
