title: Aridicins, novel glycopeptide antibiotics. II. Isolation and characterization.
abstract: A new antibacterial antibiotic complex, aridicin, was produced by a new genus, Kibdelosporangium aridum (SK&F-AAD-216). The individual factors, aridicins A, B and C, were isolated from the fermentation broth by an Amberlite XAD-7 resin extraction and purified by preparative reversed phase HPLC. The aridicins were found to be novel members of the glycopeptide class of antibiotics as exemplified by ristocetin and vancomycin, based on chemical and spectroscopic data, their molecular weights as determined by FAB mass spectrometry (1,786, 1,800 and 1,814), the detection of actinoidinic acid in their acid hydrolysates, and detailed TLC and HPLC comparisons with representative members of this class.
