AI Technical Summary

Using saturated anacardic acid as a starting material, analogues of sildenafil [a potent phosphodiesterase-5 (PDE5) inhibitor and an orally active drug for the treatment of erectile dysfunction] were synthesized, to observe the effect of the pentadecyl side chain on PDE5 inhibition. The synthesized compounds were characterized by spectral studies and tested for PDE5 inhibition, and the results were compared with those obtained with sildenafil.
