What is RING?

A RING entry is a cyclic substructure, one of the pre-calculated SUBSTRUCTURE types. RING entries can be searched using Substructure Search option.

• S0000137 Phenyl ring
• S0008610 Cyclohexane ring
• S0041199 Indole ring
• S0048704 Epoxide
• S0147135 Thiazole

BiSSCat Structure Search option

The BiSSCat Structure Search option can be used to look up compounds, functional groups, and substructures based on structural information or physicochemical properties.

• Elements: This option is used to specify the elements comprising functional groups or substructures (e.g. CO2 for carboxylate, C6O6 for sugars, etc). The number of hydrogen atoms is not taken into account unless specified explicitly.
• The database is divided into a number of subsections based on the type of data, as follows:
  • compound
  • fgroup: an index of functional groups and substructures
  • substructure: a collection of pre-calculated substructures
    • atom: an atom with physicochemical/electrochemical properties
    • vici: a central non-hydrogen atom and the atoms attached to it
    • bond: a chemical bond consisting of two non-hydrogen atoms
    • ring: a cyclic substructure
    • frag: a fragment obtained when all rotatable bonds are cut
    • skel: a carbon skeleton/backbone
    • conj: conjugated double bonds
• Properties: physicochemical and electrochemical properties
