Versatile effects of sildenafil: recent pharmacological applications.
نویسندگان
چکیده
Sildenafil is a phosphodiesterase-5 (PDE5) inhibitor and is predominantly used in the treatment of erectile dysfunction. While maintaining an excellent safety and tolerability profile in the management of erectile dysfunction, sildenafil also provides a prolonged benefit in various other diseases. Sildenafil has been shown to have a potential therapeutic efficacy for disorders related to the central nervous system and pulmonary system. In the central nervous system, it exerts its neuroprotective effects in multiple sclerosis and has a significant memory enhancing action. Sildenafil also significantly enhances neurogenesis. Several lines of evidence indicate that targeting PDE5 with sildenafil offers novel strategies in the treatment of age-related memory impairment. Guanylate cyclase/cGMP/protein kinase G pathway or glutamate/nitric oxide/cGMP pathway appears to mediate memory enhancing effects. Some of the positive cognitive features of sildenafil therapy are likely attributable to the mechanisms reviewed here. Sildenafil has been shown to reduce pulmonary hypertension and alleviate pain in animals and humans. The present review primarily focuses on the various pharmacological effects of sildenafil with regard to its influence on the nervous and pulmonary system.

Review: Current development on catalytic synthesis and pharmacological applications of 1,4-dihydropyridines
1,4-Dihydropyridines (1,4-DHPs) are recognized as one of the most versatile pharmacophores present as central core in many pharmaceuticals. Low yield and harsh reaction conditions prompted the researchers for the development of new environmental- friendly methods for the synthesis of 1,4-DHPs. This review explored the development of various green chemistry approaches using new catalysts develop...

متن کاملEffects of sildenafil treatment on the development of tolerance to diazepam-induced motor impairment and sedation in mice.
We studied the effects of sildenafil, a selective inhibitor of PDE5, on the development and the expression of tolerance to diazepam (DZ)-induced motor impairment and sedation in mice. DZ-induced motor incoordination was assessed by the rotarod and chimney tests, and DZ-induced sedation was examined using a photocell apparatus. Sildenafil treatment enhanced the development of tolerance to the mo...

متن کاملLack of effect of sildenafil on cocaine-induced convulsions in mice.
The convulsant action of cocaine and the proconvulsant effects of sildenafil, a drug which is widely used in the treatment of erectile dysfunction, have been documented both in humans and mice. Since it was reported that sildenafil alone, and in conjunction with cocaine, is used recreationally, the present study was performed to examine the influence of sildenafil on cocaine-induced seizures in...
