title: Studies on thermophile products. IV. Structural elucidation of cytotoxic substance, BS-1, derived from Bacillus stearothermophilus.
abstract: A new cytotoxic substance designated as BS-1 was isolated from the autolysate and culture filtrate of Bacillus stearothermophilus UK563. On the basis of spectral data, the structure of BS-1 was determined as bis(2-hydroxyethyl) trisulfide and confirmed by direct comparison with the synthetic compound. BS-1 exhibited potent cytotoxicity against leukemia P388-D1, leukemia P388, mastocytoma P815, lymphoma EL4 and lymphoma MOLT4.
