In order to assess the depression decreasing effect of the molecules, a forced swim protocol in rats was used to manufacture azetidinone compounds with a tricyclic nucleus. Three different procedures were used in order to synthesize the necessary compounds. Step one involved reacting anthracene-9,10-dione with hydrazine hydrate in the presence of methanol under refluxing conditions to produce 2. Next, several substituted aromatic aldehydes were refluxed with 2 under the influence glacial acetic acid as catalyst to create Schiff bases. Chloracetyl chloride was used under alkaline circumstances to accomplish cyclization in the last stage. The produced compounds 4a-e had a yield range from 61-70% and shown solubility or mild solubility in DMSO, methanol, and chloroform. Using methanol:ethyl acetate (4:6) as the solvent solution, TLC was used to evaluate the purity of the produced compounds. The compounds' Rf values ranged from 0.59 to 0.73. The compounds have a melting temperature range of 172-214°C and were produced as a white to yellow solid. The compounds demonstrated antidepressant activity that was dosage dependent. Compounds 4a, 4b, and 4d had significantly shorter immobility times (p<0.01) than the control group. It became clear that each test chemical may exhibit antidepressant activity when the dosage was increased.

Various quinoid groups have been connected with the cyclopentadithiophene (CPDT) skeleton via azine linkage to form a new D–π–A system. These compounds revealed weak absorptions extending to 590–630 nm, corresponding to small HOMO–LUMO gaps of 1.97–2.10 eV. Their reduction potentials were strongly dependent on the quinone moieties, whereas the oxidation potentials were controlled by the CPDT moiety. Some of these compounds underwent oxidative polymerization under electrochemical conditions to yield polymers with a highly amphoteric character.
