Kanchanomycin for neoplastic cells in culture at extremely low concentrations (.., 1963; .., 1965). In HeLa cell culture assays, it has a cytotoxic end point of 0.002 μg/ml and a cellular lethal end point of 0.05 μg/ml. In this system, kanchanomycin is more cytotoxic than streptonigrin, mitomycin C or actinomyci

Quinoxaline Antibioticscule (..., 1961). These colorless antibiotics are derived from various species of Streptomycetes and are highly active against gram-positive bacteria. They also exhibit a cytotoxic effect on cultured cells. The antibiotics were shown to inhibit various experimental tumors (..., 1955; ..., 1959; . an

The field of molecular biology itself was in its relative infancy during the preceding decade and the unique role played by many anti biotics in the development of our understanding of nucleic acid synthesis and f
