DEFINITION

Classification: 536/27.1

N-glycosides wherein the N is part of an N-hetero ring which hetero ring is part of a polycyclo ring system containing an N-hetero ring and an additional hetero ring (e.g., rebeccamycin, etc.):

(under subclass 22.1) Compounds which are N-glycosylamines wherein the N of the N-glycoside moiety is part of a nitrogen containing hetero ring which hetero ring is part of a polycyclo ring system that contains the N-hetero ring and an additional hetero ring.

(1) Note. This and indented subclasses do not provide for compounds that contain a phosphorus ester group attached to the sugar moiety.

(2) Note. Nucleosides are provided for in this and indented subclasses.

(3) Note. An example of a compound provided for herein is rebeccamycin: [figure]
