Chemical Class definition

Chemical Class. Compounds shall be deemed to fall within the same Chemical Class if one compound is a homolog, isomer, analog or first order derivative of another compound. A compound is a "homolog" of another compound if it differs from that compound by a methylene group or an ethylene group or a similar or equivalent group that does not affect the relationship of the functional groups in the compound that give rise to its activity as a uPA Inhibitor. An "isomer" is a compound differing from another compound by positional isomery, geometric isomery or stereochemical isomery. An "analog" is a compound which differs from another compound by the replacement of a single group within the latter compound. A compound is a "first order derivative" of another compound if it is derived from that compound by a single chemical reaction.
