Bis Basic Substituted Diaminobenzobisthiazoles as Potential Antiarthritic Agents

Cullen, Ernest,Becker, Reinhold,Freter, Kurt,LeClerq, Thelma,Possanza, Genus,Wong, Hin-Chor

, p. 350 - 361 (2007/10/02)

A series of benzobisthiazoles were screened for antiinflammatory activity in the carrageenan paw edema and adjuvant arthritis tests.Compound 26, 2,6-bis(N,N-diethylamino)benzobisthiazole, was found to inhibit the swelling of the uninjected paw in the prophylactic adjuvant arthritis model with an ED50 of 2.3 mg/kg orally.As with most compounds of this series, 26 was inactive in acute model of inflammation, such as paw edema: like steroids, it showed activity in the granuloma pouch assay but did not inhibit cyclooxygenase, indicating a mode of action different from the classical nonsteroidal antiinflammatory drugs (NSAID's).At doses higher than those producing antiinflammatory activity, 26 had some immunoregulating properties.
