Novel antibiotics named kigamicin A, B, C, D, and E were discovered from the culture broth of Amycolatopsis sp. ML630-mF1 by their selective killing activity against PANC-1 cells only under a nutrient starved condition. Under a condition of nutrient starvation, kigamicins A, B, C, and D inhibited PANC-1 cell survival at 100 times lower concentration than in normal culture. Kigamicins showed antimicrobial activity against Gram-positive bacteria including methicillin resistant Staphylococcus aureus (MRSA). Kigamicin D inhibited the growth of various mouse tumor cell lines at IC50 of about 1 microg/ml.

Kigamicin A (1), B (2), C (3), D (4) and E (5) are novel antitumor antibiotics. Their structures were determined by spectroscopic analyses including various NMR measurements. Kigamicins have a unique aglycone of fused octacyclic ring system containing seven of six-membered rings and one oxazolidine. The aglycone links a sugar chain composed of one to four deoxysugars. These sugars were found to be amicetose and oleandrose.
