A novel series of potential phosphodiesterase-4 (PDE-4) inhibitors, 6-(3-(cyclopentyloxy)-4-methoxyphenyl)-3-aryl-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazines, were developed. Different concentrations of the synthesized compounds were tested on cultured NIH-3T3 cells in order to determine their safety and efficacy in NIH-3T3 mouse fibroblastic cells in comparison to rolipram, a selective PDE-4 inhibitor. The viability of cells was determined by (3-(4,5-dimethylthiazol-2-yl)-2,5-di-phenyltetrazoliumbromide (MTT) assay. The PDE inhibition rate was measured indirectly by determination of concentrations of extracellular cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) using enzyme-linked immunoassay technique. The results showed that, all tested compounds caused a marked increase in the concentration of cAMP, whereas the concentration of cGMP stayed approximately unchanged. The cytotoxic IC(50) of all synthesized compounds were approximately two folds greater than their required concentration for inhibition of PDE-4 (in term of elevation of cAMP) and thus these structures could be used to develop potent and safe inhibitors of PDE-4 enzyme.
