Abstract
|
|
|
Anti-inflammatory effects of three potassium salts of N,N-disubstituted 4-aminoazobenzene-sulfonic acids were investigated and compared to that of acetylsalicylic acid (ASA) in rats with adjuvant arthritis (AA). Prophylactic oral administration of all compounds in a dose of 150mg/kg ameliorated AA symptoms in animals. The most pronounced anti-inflammatory activity at the end of the experiment showed compound 1 containing imino group: it significantly suppressed joint swelling by 48.2% in female and by 44.2% in male rats with AA. The development of polyarthritis after the treatment with this compound was the lowest in female (20%) and male (40%) rats (in control - 100% of animals with polyarthritis). All derivatives, and especially compound 1, also improved the systemic parameters of disease such as blood indices and internal organs¡¯ weight, and showed no toxicity on the main organs such as liver and spleen.
