Abstract
Series of benzothiazoles were synthesized and evaluated their inhibitory activities for NO production in lipopolysaccharide-activated macrophages. The most potent compound was the indole-containing benzothiazole 3c with 4.18μM of IC(50). The mechanistic study suggested that benzothiazoles inhibited NO production by the suppression of iNOS protein and mRNA expression. They also suppressed the expression of COX-2 through the NF-κB inactivation.
