Definitions:

Antiaromatic

Antiaromaticity describes molecules that fail to comply with Huckel's rule, having conjugated pi systems with 4n π electrons that lead to destabilization.

Nonaromatic

Referring to organic compounds that do not have the aromatic stability associated with the delocalized pi electrons in a ring structure.

Aromatic Heterocycles

Rings of carbon atoms containing at least one non-carbon atom (heteroatom) like nitrogen, oxygen, or sulfur, that are stable due to aromaticity, important in many biological molecules and synthetic compounds.

Inflammatory Diseases

Disorders characterized by inflammation, which involves redness, swelling, pain, and sometimes loss of function, due to an immune response.
