Abstract
  • Three new cytochalasans, named cytochalasins Z1, Z2 and Z3, were isolated from the wheat culture of Pyrenophora semeniperda, a fungus proposed to biologically control grass weeds. Other cytochalasins isolated from the same organic extract were identified as the already known cytochalasins F, T, deoxaphomin and cytochalasins B, the latter being produced in very large amounts. All three new cytochalasins were characterized as 24-oxa[14]cytochalasans by extensive use of NMR and MS techniques. Cytochalasins Z1 and Z2 proved to be structurally related to cytochalasin T, whereas cytochalasin Z3 was related to cytochalasin B. When assayed on wheat and tomato seedlings, cytochalasin Z3, in comparison to the new cytochalasins, cytochalasin B, its 21,22-dihydroderivative, cytochalasin F and deoxaphomin showed a remarkable ability to inhibit root elongation. The possibility of using these metabolites in biological control strategies is discussed. (literal)
