Anion Effects: Different salts were added to determine if solvent composition has an effect on the maximum absorbance. The mixture between the complex and sodium fluoride had a significant reduction in the color of the complex. This could result from iron (III) binding to the fluoride…

    In conclusion, we reported the synthesis of fused and isolated triazoles based on thieno[2,3-d]pyrimidines. The synthesized 1,2,4-triazolo compounds were screened for their anticancer activity at a concentration of 10 μΜ against a panel of 60 cell lines derived from nine different types of cancers, and also screened for their PDE 5 inhibitory activity. The possibility of combining 1,2,4-triazolo moiety to thieno[2,3-d]pyrimidines should open new opportunities for the rational design of…
