title: PD 113,618 and PD 118,309, new pactamycin analogs.
abstract: Two antibiotics were isolated from culture broths of a Streptomyces sp. and identified as 8"-hydroxypactamycin and 7-deoxypactamycin. The latter antibiotic was shown to be identical to cranomycin. An additional compound, 8"-hydroxypactamycate, was also isolated.
