Abstract

Cyclosporin A, a Peptide Metabolite from Trichoderma polysporum (L INK ex P ERS.) Rifai, with a remarkable immunosuppressive activity Two antifungal metabolites, cyclosporins A and C, were isolated from a strain of Trichoderma polysporum (L INK ex P ERS.) Rifai. Cyclosporin A, the main component, has the molecular formula C 62 H 111 N 11 O 12 as deduced by NMR. and mass spectra. Hydrolytic cleavage of cyclosporin A furnished 11 amino acids as fragments, among them an artefact of a new C 9‐amino acid. The amino acid sequence was determined by Edman degradation of iso‐cyclosporin A, a basic rearrangement product formed from cyclosporin A by N, O‐acyl migration. In an independent investigation an X‐ray analysis of the iodo derivative 10 was performed (see the following paper). On the basis of the chemical, spectroscopic and crystallographic evidence the complete structure of cyclosporin A was elucidated as the neutral cyclic oligopeptide 1. Cyclosporin A and C show remarkable immunosuppressive and antiphlogistic activities in several pharmacological models.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
