## Abstract The ^15^N NMR spectra of ten isocyanates, four isothiocyanates, and four __N__βsulfinylamines have been obtained at the naturalβabundance level by highβresolution NMR spectroscopy. The results show that isocyanates and isothiocyanates have ^15^N chemical shifts over 200 ppm toward highe
Actinomycin D (ACD), Figure 1, is the most important member of a family of naturally occurring actinomycine whose primary biological function is the inhibition of DNA dependent RNA synthesis (5). If mechanisms propoaed for the biological activity of ACD ( 6) are to have a plausible structural basis,
