| Abstract: | New antibiotics, T1801 A, B, C, and D, were isolated from the culture broth of Pseudomonas sp. SC-1801. Their structures were found by spectroscopic analyses to be tri- and tetra(methylthio) derivatives of hydro quinone (T1801 A and C) or p-benzoquinone (T1801 B and D). They are new quinone and hydroquinone antibiotics and are active against Gram-positive bacteria, some fungi, and yeasts. |
