kodien
Kodien refers to a family of synthetic organic compounds that share a common structural feature: a bicyclic ring system consisting of a benzene ring fused to a pyridine ring. This core structure is known as isoquinoline. The term "kodien" itself is not a standard scientific nomenclature but appears to be a specific, potentially colloquial or internal, designation for compounds belonging to or derived from this isoquinoline scaffold.
Compounds within the kodien family can exhibit a wide range of chemical properties and biological activities
