The modifying effects of topical application of a catechol antioxidant protocatechuic acid (PA) on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammatory responses in mouse skin were investigated. Treatment with a high dose (20,000 nmol) of PA, based on time of application, modifies
Natural or synthetic melanin (CAS 8049-97-6) is a high molecular weight heteropolymer, product of the enzyme tyrosinase, found to possess radical scavenging and antioxidant functions. It was of interest, therefore, to study in detail the possible anti-inflammatory and/or immunosuppressive properties
Hymexazol is an efficacious and widely used fungicide. However, its environmental toxicological assessment has not been well documented. It had no report of its toxicity to fish embryo.
