چکیده

A new antitumor antibiotic, fredericamycin A (FCRC-A48, NSC-305263), has been isolated from a strain of Streptomyces griseus (FCRC-48). Based on its unique ultraviolet-visible spectrum, infrared spectrum, proton and carbon-13 nuclear magnetic resonance spectra and mass spectra, it is judged to be a novel acid-base indicator type of compound. Its production, isolation and physicochemical properties are discussed. The isolation, ultraviolet-visible spectrum and some biological properties of two minor components, fredericamycin B and fredericamycin C, are also described.

Fredericamycin A, a new antitumor antibiotic. II. Biological properties.

Fredericamycin A is a novel antibiotic produced by a soil isolate of Streptomyces griseus (FCRC-48). In vitro, fredericamycin A exhibits antibacterial, antifungal, and cytotoxic activities. In vivo, fredericamycin A exhibits very good antitumor activity against P388 mouse leukemia as well as the CD8F mammary tumor and marginal activity against B16 melanoma. Fredericamycin A failed to demonstrat...

Chicamycin, a new antitumor antibiotic. I. Production, isolation and properties.

Chicamycin is a new antitumor antibiotic produced by a strain of Streptomyces albus, No. J576 -99. The antibiotic is extractable into organic solvents from the fermentation broth and is obtained in two active forms, chicamycins A and B, depending upon the isolation procedure used. Chicamycin A is not a natural antibiotic but the methanol adduct of naturally produced chicamycin B. Both forms of ...

The antibiotic YA-56 complex: isolation, purification and physicochemical properties of the main components.

Isolation, purification and physicochemical properties of the antibiotic complex YA-56, a family of phleomycin-bleomycin group, are described. The antibiotic YA-56 complex was found to be composed mainly of two active components named YA-56X and Y. These components were clearly differentiated from the reported phleomycins and bleomycins by their physicochemical properties. However, by direct co...
