Twelve 4-substituted cyclopenta[c]quinoline derivatives were synthesized and evaluated in vitro cytotoxicity against four human cancer cell lines (HOP62, SK-OV-3, MD-MB-468 and T-47D). The compounds 6c and 6e bearing p-anisidine and pyrrolidine side chain were more active than the others.

In the course of searching for biologically active sesquiterpenoids from Curcuma genus, two sesquiterpenoids were isolated from the rhizome of Curcuma zedoaria (Zingiberaceae). Their structures were identified as ar-turmerone (1) and $\beta$-turmerone (2). The structure elucidation of compounds 1 and 2 was carried out by comparison of their physical and spectral data with previously reported values.

Bromolactonization of 2-substituted-1-cyclohexenyl-1-acetic acids with 1, 3-dibromo-5, 5-dime-thylhydantoin 9DBH) and potsssium tertiary butoxide (t-BuOK0 in anhydrous DMF was found to proceed in a highly regioselective manner. The reaction predominantly resulted in the formation of ${\betha}-lactones$ (greater than 96%).

2-Bromo (2'-benzofury)gloxal-2-aryhydrazones I reacted with nucleophiles displacing the bromide. Treatment of I with active methylene compounds yield the pyrazole derivatives VIII-XI. Compounds XII-XIV reacted with hydrazine to give pyrazolo (3, 4-dipyridazine derivative XIV-XIV. The structures of the products were assigned and confirmed on the basis of their elemental analysis and spectral data.

A convenient method for the preparation of imidazobenzimidazole 3, imidazoimidazole 5, imidazotriazole 6 and pyrano [2, 3-c] oxazole 7 derivatives is described. This depends on interaction of 2-methyl-4-arylidene-2-oxazolin-5-ones 1 with o-diamines, thiosemicarbazide and/or ethylcyanoacetate. The effect of alcoholic potassium cyanide on axazolinone 1 was studied. Antibacterial activity of the obtained products was studied.

The efficient synthetic routes to cis-1-ethenyl-2-hydroxymethyl-cyclohexane, an useful synthetic intermediate, have been described. Access to the cis-disubstituted cyclo hexane is gained through the Clasen rearrangment and selective DHP protection of diol respectively.

Polyhydroxystilbenes including resveratrol were reported to competitively inhibit monoamine oxidase-A-without structural relation with substrates and cynthetic inhibitors for the enzyme. We attempt to explore a plausible mechanism for their inhibitory activity on MAO-A. All the polyhydroxystilbenes tested showed the antioxidant activity on liver homogenate. Furthermore, the antioxidant activity turned out to closely correlate with the MAO-A inhibitory activity.
