Pirenoxine
Based on 1 Customer Validation
Pirenoxine (Catalin K) is an antioxidant with lens-protective activity. Pirenoxine inhibits lens sclerosis, prevents lipid peroxidation and suppresses lens protein opacification. Pirenoxine blocks benzoquinone acetic acid-induced cataract progression. Pirenoxine can be used in research related to presbyopia and cataracts.

Pirenoxine inhibits lens protein opacification induced by UVC, selenite and Ca2+[1][2].
Pirenoxine (PRX) (0.016-0.1 μM; 0-4 days) delays selenite-induced early lens opacification and reduces the degradation of insoluble lens proteins in lens homogenates of SD rat pups[2].
Pirenoxine reduces UVC-induced lens opacity and γ-crystallin degradation in porcine lens homogenates; it delays the onset and reduces the opacity of glucose/galactose-induced diabetic cataracts in intact goat lenses[2].
Pirenoxine (10-4 M) elevates the levels of glutathione (GSH), water-soluble proteins and sulfur-containing amino acids in lenses of galactose-induced diabetic SD rats, while it only produces partial effects at 10-5 M[2].
Pirenoxine inhibits oxidative damage in intact rat lenses induced by macrophages stimulated with Fe3+/ascorbic acid, hemoglobin or fMLP; it also inhibits lipid peroxidation in intact rat lenses treated with ROS induced by xanthine/xanthine oxidase[2].
Pirenoxine (60 μM; 48 h) reduces sorbitol content in bovine lenses[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Pirenoxine (0.005% concentration; topical administration; 4 times daily; for 120 consecutive days) delays the progression of age-related cataracts in senescence-accelerated mice[2].
Pirenoxine (2.5-5 mg/kg; subcutaneous injection; single administration) prevents early gross lens opacification in selenite-induced cataract SD young rats only at the dose of 5 mg/kg[2].
Pirenoxine (PRX) (0.8 mg/15 mL; topical administration; three times daily for 7 consecutive days) increases the activities of antioxidant enzymes and the level of GSH, while reduces the levels of oxidative damage markers in Wistar rats with selenite-induced cataracts[2].
Pirenoxine (concentration 0.005-2%; topical administration; 2 drops, three times daily; for 30 consecutive days) reduces the incidence of cataracts in galactose-induced diabetic cataract SD rats and tryptophan deficiency-induced congenital cataract colored rabbits, and improves the antioxidant/protein-related indicators of their lenses[2].
Pirenoxine (concentration 0.0053%; topical administration; three times daily; for 60 consecutive days) slows disease progression and reverses lens opacification in Wistar rats with established galactose-induced diabetic cataracts[2].
