Background
Herbicidin A is an adenine nucleoside antibiotic originally isolated from S. saganonensis that exhibits herbicidal activity, particularly against dicotyledonous plants. It prevents rice seed germination (MIC = 6.25 ug/ml) and completely protects young rice plants from X. oryzae-induced leaf blight when applied at 100 ppm. In HEK293 cells, herbicidin A inhibits TNF-α-induced NF-κB activity and induces cytotoxicity (IC50s = 1.8 and 2.7 uM, respectively).
