Abstract:
A variety of novel N-arylidene-N'-[5-(4-isobutylphenyl)-[1,2,4]-triazin-3-yl] hydrazines 4, carboxylic acid N'-[5-(4-isobutylphenyl)-[1,2,4]-triazin-3-yl] hydrazides 5, triazolotriazines 6 and other related triazine derivatives were synthesized. Several synthetic routes were employed to access the desired compounds from 5-(4-isobutylphenyl)-[1,2,4]-triazin-3-yl hydrazine 3 as a parent compound. The analgesic and anti-inflammatory activities of the synthesized compounds were studied. The results showed that compound 4 g exhibited pronounced analgesic activity, while compound 4f displayed the highest anti-inflammatory activity. Meanwhile, compound 6d evoked dual analgesic-anti-inflammatory effect without any ulcerogenicity.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
