Subject matter under cross-reference art collection 10 containing peptides or proteins which contain at least one ring formed through a peptide or nonpeptide bond.
(1) Note. In addition to the cyclic peptides containing at least one ring formed only through peptide bonds, included in this subclass are those cyclic compounds in which the peptide bond may be other than that formed by the alpha amino nitrogen, e.g., through the 4-amino group of 2,4 diamino butanoic acid and the cyclic compounds in which one or more links in the ring are nonpeptide bonds (heterodectic cyclic peptides).
(2) Note. Excluded from this art collection are those compounds which are cyclic because they contain intrachain disulfide bridges and those compounds appropriate for art collections 40-170.
