Pharmacotherapy of erectile dysfunction: Current standards

open access: yesIndian Journal of Urology, 2006
Pharmacotherapy is currently the therapeutic option of choice for erectile dysfunction. Comprising mainly intracavernosal injection therapy using alprostadil or alprostadil combined with phentolamine and/or papaverine and oral phosphodiesterase-5 ...

Medium dependence of asphaltene agglomeration inhibitor efficiency [PDF]

open access: yesEnergy & Fuels vol.22, 2008, pp 1917 - 1922;, 2007
Applying chemical additives (molecule inhibitors or dispersants) is one of the common ways to control asphaltene agglomeration and precipitation. However, it is not clear why at some conditions the synthetic flocculation inhibitors as well as resins not only do not inhibit the asphaltene agglomeration,, they may also promote it, and why the increasing ...

New Deoxycholic Acid Derived Tyrosyl-DNA Phosphodiesterase 1 Inhibitors Also Inhibit Tyrosyl-DNA Phosphodiesterase 2

open access: yesMolecules, 2021
A series of deoxycholic acid (DCA) amides containing benzyl ether groups on the steroid core were tested against the tyrosyl-DNA phosphodiesterase 1 (TDP1) and 2 (TDP2) enzymes.

Estimating the rate constant of cyclic GMP hydrolysis by activated phosphodiesterase in photoreceptors [PDF]

open access: yesTHE JOURNAL OF CHEMICAL PHYSICS 129, 145102 (2008), 2008
The early steps of light response occur in the outer segment of rod and cone photoreceptor. They involve the hydrolysis of cGMP, a soluble cyclic nucleotide, that gates ionic channels located in the outer segment membrane. We shall study here the rate by which cGMP is hydrolyzed by activated phosphodiesterase (PDE).

Investigational phosphodiesterase inhibitors in phase I and phase II clinical trials for Alzheimer’s disease

open access: yesExpert Opinion on Investigational Drugs, 2017
Introduction: Phosphodiesterase (PDE) inhibitors improve signaling pathways in brain circuits by increasing intracellular cyclic adenosine monophosphate (cAMP) and/or cyclic guanosine monophosphate (cGMP).

Phosphodiesterase-5 inhibitors use and risk for mortality and metastases among male patients with colorectal cancer

open access: yesNature Communications, 2020
Phosphodiesterase-5 (PDE5) inhibitors have been suggested to have an anti-tumor effect and block surgery-induced immunosuppression. Here, the authors show that postdiagnostic use of PDE5 inhibitors is associated with a decreased risk of colorectal ...

Phosphodiesterase-4 Inhibitors for the Treatment of Inflammatory Diseases

open access: yesFrontiers in Pharmacology, 2018
Phosphodiesterase-4 (PDE4), mainly present in immune cells, epithelial cells, and brain cells, manifests as an intracellular non-receptor enzyme that modulates inflammation and epithelial integrity. Inhibition of PDE4 is predicted to have diverse effects

Novel structural features of CDK inhibition revealed by an ab initio computational method combined with dynamic simulations [PDF]

open access: yesJournal of Medicinal Chemistry 49, 5141-5153 (2006), 2008
The rational development of specific inhibitors for the ~500 protein kinases encoded in the human genome is impeded by a poor understanding of the structural basis for the activity and selectivity of small molecules that compete for ATP binding. Combining classical dynamic simulations with a novel ab initio computational approach linear-scalable to ...

Spontaneous center formation in Dictyostelium discoideum [PDF]

open access: yesScientific reports 9, no. 1 (2019): 3935, 2018
Dictyostelium discoideum (D.d.) is a widely studied amoeba due to its capabilities of development, survival, and self-organization. During aggregation it produces and relays a chemical signal (cAMP) which shows spirals and target centers. Nevertheless, the natural emergence of these structures is still not well understood.
