Abstract

A new thiol protease inhibitor, named E-64, was isolated from the extract of a solid culture of Aspergillus japonicus TPR-64 freshly isolated from soil.E-64 was obtained as white needles and the empirical formula was estimated to be C15N5-H27O5 (M.W. 357).This was almost neutral in its electrophoretic behavior and proved to be a specific and strong inhibitor toward thiol protease such as papain and cathepsin B. They combine equimolecularly and irreversibly.

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.
