| Lentinellic Acid, a Biologically Active Protoilludane Derivative from Lentinellus Species (Basidiomycetes) [1]  | | | Abstract
| A new antimicrobial and cytotoxic sesquiterpenoid, lentinellic acid (1), has been isolated from submerged cultures of Lentinellus ursinus and L. omphalodes. The structure of the antibiotic was elucidated by spectroscopic methods and a single crystal X-ray analysis. 1 may be formed biogenetically by condensation of a protoilludane aldehyde 4 with a malonate unit. | | |

| Phellodonic Acid, a New Biologically Active Hirsutane Derivative from Phellodon melaleucus (Thelephoraceae, Basidiomycetes) [1]  | | | Abstract
| A new hirsutane derivative, phellodonic acid (1), has been isolated from fermentations of Phellodon melaleucus strain 87113. Its structure was elucidated by spectroscopic methods. The compound exhibits antibiotic activities towards bacteria and fungi. 1 is the first bioactive metabolite from cultures of a species belonging to the family Thelephoraceae. | | |

| Kuehneromycins A and B, Two New Biological Active Compounds from a Tasmanian Kuehneromyces sp. (Strophariaceae, Basidiomycetes)  | | | Abstract
| G erh ard E rk e l3, K irsten L o ren zen 3, Timm A n k ea, R obert V eltenb, A lb erto G im en ezb, and W olfgang Steglichb In a search for new inhibitors of RNA-directed DNA-polymerases kuehneromycin A (1) was isolated from fermentations of a Tasmanian Kuehneromyces species. Its structure was elucidated by spectroscopic methods. Kuehneromycin A (1) is a non-competitive inhibitor of avian myeloblastosis virus (Kj 200 ^i m) and moloney murine leukemia virus (K; 40 (.i m) reverse transcriptases. The second compound, kuehneromycin B (2) is a strong inhibitor of platelet aggregation stimulated with different inducers. In addition, both compounds exhibit cytotoxic and antimicrobial activities. | | |

| 9 ß-Hydroxymarasmic Acid and Other Sesquiterpenoids from Submerged Cultures of a Basidiomycete [1]  | | | Abstract
| 9 ß-Hydroxymarasmic acid, a new sesquiterpenoid, marasmic acid and isovelleral were isolated from cultures of a basidiomycete. Comparison of the antimicrobial activity of the three natural compounds together with two n-butyl ether derivatives of marasmic acid revealed MICs against bacteria in the range of 0 .2 —20 ng/ml. The antifungal, cytotoxic and phytotoxic activities of isovelleral were similar to those exhibited by marasmic acid, whereas the marasmic acid deriva tives were considerably less active than the parent compound. Isovelleral was the only compound to show hemolytic activity. | | |
