Derivatives of celecoxib that lack cyclooxygenase inhibitory activity but have improved PDE5 inhibitory activity are provided along with pharmaceutical compositions containing them for the treatment or prevention of cancer. Such compounds are expected to have reduced toxicity compared with celecoxib and other cyclooxygenase inhibitors, and greater efficacy compared with conventional PDE5 inhibitors. Derivatives of celecoxib are also suitable for treating chronic inflammatory conditions, erectile dysfunction, pulmonary hypertension, congestive heart failure, and enhancement of cognitive function.

trisubstituted pyrazoline scaffold derived from the COX2 inhibitor, celecoxib, was used to develop novel PDE5 inhibitors. Novel pyrazolines were identified with potent PDE5 inhibitory activity lacking COX2 inhibitory activity. Compound d12 was the most potent with an IC50 of 1 nM, which was three times more potent than sildenafil and more selective with a selectivity index of >10,000-fold against all other PDE
