Paeciloquinones A,B,C,D,E and F: New Potent Inhibitors of Protein Tyrosine Kinase Produced by Paecilomyces carneus. II. Characterization and Structure Determination.
摘要:
Paeciloquinones A to F and versiconol have been isolated as inhibitors of protein tyrosine kinases from the culture broth of the fungus Paecilomyces carneus P-177. The structures of the new anthraquinones were determined by spectroscopic methods, mainly 1H NMR and 13C NMR. The substitution pattern was established by investigation of the respective methylated derivatives.
