    The causes of erectile dysfunction are many, endocrine disorders neuropathy, vascular disease, diabetes control nutrition, psychogenic factors, as well as drugs used in the treatment of these complications all play a role [1]. The National Institute of Health Consensus Panel reported that ED affects as many as 30 million men in the United States [2]. Diabetes mellitus is strongly associated with the development of ED, with a reported prevalence of ED of 35-90% in those with diabetes in different populations [3]. The pathophysiology of ED in diabetes is multifactorial. Under normal circumstances, both biological and psychological factors work synchronously resulting in an erection [4]. Based on questionnaire responses by 1709 men, 35% of men reported moderate to complete ED. Overall prevalence rates were 39% in men 40 years of age, 48% in those 50 years of age, 57% in those 60 years of age, and 67% in those 70 years of age [5]. Ar reaction products, apparently through the proposed dipolar high-energy transition states TS-1 and TS-2 under MW irradiation, respectively. In contrast, conventional heating failed to produce similar results, even after prolonged heating. Compound 10, upon chlorosulfonation followed by the coupling of various nucleophiles, yielded a series of compounds 12–20 as analogs of sildenafil (21). Compounds 12–21 were subjected to tyrosinase inhibition studies and SAR studies were carried out. This study reflected that the inhibition was enhanced with increase of carbon chain. In case of the compound 17, the –OH group was replaced with –CH–OH with a resulting increase in inhibition against tyrosinase. Compound 17 was found to be more potent than the potent reference inhibitor LM and KA.

Was the first PDE5 inhibitor found to be effective in promoting spontaneous penile erections. While the mechanistic basis for this effect has become obvious in retrospect, it was initially noted as a frequent side effect of an NCE that originally entered the clinic for the treatment of congestive heart failure. Thus the utility of Allsosteric activators of s GC like A-350619 (19) and BAY 41-2272 (20) can elicit penile erection in animals synergistically enhancing the effects of NO by stimulating c GMP synthesis without altering degradation of the cyclic nucleotide. It’s discovery started from a task to find a molecule that would bind to PDE, so that it could convert c GMP to the inactive GMP form as a potential drug for treatment hypotension and angina. In Phase I studies, volunteers reported about some side effects, among which was the unexpected side effect of a change in erectile function. This observation changed the medical management of erectile dysfunction. Phase II trials of , a selective inhibitor of PDE-5, the main phosphodiesterase isoform responsible for hydrolysis of intracellular cyclic guanosine monophosphate, has been used by millions of men for the treatment of erectile dysfunction with significant improvements in erectile function provides a prolonged benefit in various other diseases. Promising results have been reported for patients with treated prostate cancer, end-stage renal failure, Parkinson disease, spina bifida, and in multiple organ transplant recipients.
