Use of Ascamycin

Ascamycin is a 5'-O-sulfonamide ribonucleoside antibiotic produced by Streptomyces sp. JCM9888. Ascamycin has a selective antibacterial activity against Xanthomonas species with MIC values of 0.4 μg/mL, 12.5 μg/mL and 12.5 μg/mL for Xanthomonas citri, Xanthomonas oryzae and Mycobacterium phlei, respectively[1][2][3].

Description	Ascamycin is a 5'-O-sulfonamide ribonucleoside antibiotic produced by Streptomyces sp. JCM9888.

Target	MIC: 0.4 μg/mL (Xanthomonas citri), 12.5 μg/mL (Xanthomonas oryzae) and 12.5 μg/mL (Mycobacterium phlei)[1]
In Vitro	The Ascamycin has C2-chloroadenine as the base on C-1' which lacks the chlorine[1]. Ascamycin has a selective antibacterial activity against Xanthomonas species. When Ascamycin is dealanylated, Dealanylascamycin shows a broad antibacterial activity against various Gram-negative and Gram-positive bacteria. Xanthomonas citri is susceptible to Ascamycin by virtue of the Ascamycin-dealanylating enzyme on the cell surface[2].
