Synthesis and anticonvulsant activity of some piperazine derivatives
Abstract:
Various 1,4-substituted derivatives of piperazine (I-XII) were synthesized and evaluated for their anticonvulsant activity in the maximal electroshock (MES) and subcutaneous pentylenetetrazole (ScMet)--induced seizures and for neurotoxicity (TOX) in the rotorod test in mice and rats. The most promising compounds seem to be 1-[(2,4,6-trimethyl)-phenoxyethyl]-4-(2-hydroxyethyl)-piperazine dihydrochloride (II) and 1,4-bis-[(4-chloro-3-methyl)-phenoxyethyl]-piperazine dihydrochloride (X) which displayed anti-MES activity with their protective index (PI) higher than that for valproate II (rats), X(mice)).

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.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
