Biological Activity

Macrolide |
Concanamycin A can come from S. diastatochromogenes, as a microbial metabolite with immunomodulatory activity[1].
Concanamycin A (100 nM; 0-20 h) results DNA fragmentation in CD4+ and selectively induces CD8+ T cells rapid cell death between normal and the immunized mice source, while CD8+ population in mice immunized is more sensitive[2].
Concanamycin A (3-50 nM; 16 h) inhibits LPS-induced NO production in elicited peritoneal macrophages, but (25 nM; 7 h) doesn’t inhibit LPS-induced TNF-α production[3].
Concanamycin A (0.01 nM-1 nM) inhibits the acidification of rat liver lysosomes (IC50 =0.061 nM), and inhibits oleate incorporation into cholesteryl ester (IC50 =14 nM)[4].

-
Concentration:100 nM
-
