midazolines was prepared and evaluated for central nervous system (CNS) effects (antidepressant, anticonvulsant, muscle relaxant, and depressant) in animal models. Some separation of those CNS activities was achieved through substitutions on the phenyl and imidazoline moieties. Halo-substituted phenyl compounds were among the most potent antidepressants in this series, while imidazole N-alkylation
A series of 12 alpha -deoxoartemisinyl cyanoarylmethyl dicarboxylates (4a-4o), dicarboxylic acids 12 alpha -deoxoartemisinyl ester cyanoarylmethyl amide (5a-5k), and dicarboxylic acids 12 alpha -deoxoartemisinyl ester N-methylcyanoarylmethyl amide (6a-6l), showing moderate cytotoxicity against P388 and L1210 cells were prepared. They induced the significant accumulation of L1210 and P388 cells in the G1 phase of the cell cycle. This mechanism of action was quite different from that of the majority of cytotoxic compounds used in the chemotherapy of cancer. Compound 4b possessed better cytotoxicity than the other compounds.

Design, synthesis and antioxidant properties of ovothiol-derived 4-mercaptoimidazoles
Fourteen 4-mercaptoimidazoles derived from the naturally occurring family of antioxidants, the ovothiols, have been synthesized by cyclization of thioamides with trimethylsilyl trifluoromethanesulfonate (triflate). These compounds have been assayed for their radical-scavenging activity.

The preparation of a novel mesoionic heterocycle is described; derivatives of 4-aryl-5-alkyl-1,2,5-thiadiazolium-3-olates (6a–f) are obtained by treatment of α-N-substituted aminophenylacetamides with sulphur monochloride followed by base.
