Potential trichothecene photoaffinity reagents were prepared by coupling either the C-4 or C- 15 alcohols derived from anguidine with (3-azido-5-methoxyphenoxy) acetic acid, 4-(3-azido- 5-methoxyphenoxy) butyric acid, or N-(3-azido-5-methoxyphenyl) N'-(carboxymethyl) urea. The C-15 anguidine deriviatives of (3-azido-5-methoxyphenoxy) acetic acid and (3-azido-4- iodo-5-methoxyphenoxy) acetic acid possessed protein synthesis inhibition activity ...
