Summary
Ruthenium-derived nitric oxide (NO) donors show potential for hypertension treatment. These compounds release NO through reduction or light, impacting vasodilation and arterial pressure via sGC and potassium channels.
Area of Science:
- Inorganic Chemistry
- Pharmacology
- Cardiovascular Physiology
Background:
- Nitric oxide (NO) donors are crucial for vasodilation and hypertension management.
- NO plays a vital role in regulating vascular tone and arterial pressure.
- Pharmacological strategies utilizing NO donors offer an alternative for hypertension treatment.
Purpose of the Study:
- To review the physicochemical properties of ruthenium-derived NO donor complexes.
- To highlight complexes synthesized in our group over the past decade.
- To discuss the vasodilation and arterial pressure effects of these ruthenium complexes.
Main Methods:
- Focus on ruthenium complexes releasing NO via reduction and light stimulation.
- Analysis of structure-activity relationships for vascular effects.
- Discussion of NO targets: soluble guanylyl cyclase (sGC) and potassium channels.
Main Results:
- Ruthenium complexes demonstrate controlled NO release mechanisms (reduction and light).
- These complexes effectively induce vasodilation and control arterial pressure.
- The chemical structure of ruthenium complexes is critical for their vascular activity.
Conclusions:
- Ruthenium-derived NO donors represent a promising class of compounds for cardiovascular applications.
- Understanding the chemical structure is key to optimizing NO release and therapeutic effects.
- These inorganic compounds offer a novel pharmacological approach to managing hypertension.

01:23Antihypertensive Drugs: Vasodilators
2.5K
Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...

01:19Complexation Equilibria: The Chelate Effect
1.7K
In complexation reactions, metal atoms or cations interact with ligands to form donor-acceptor adducts called metal complexes. Ligands that bind through one donor site are monodentate, ligands with two donor sites are bidentate, and those with more than two donor sites are polydentate ligands. For example, ethylene diamine is a bidentate ligand that binds through two nitrogen donor atoms, forming a five-membered ring. EDTA is a polydentate ligand that binds through four oxygen and two nitrogen...

01:23Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
611
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

19.2K
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

01:11ortho–para-Directing Activators: –CH3, –OH, –NH2, –OCH3
5.0K
All ortho–para directors, excluding halogens, are activating groups. These groups donate electrons to the ring, making the ring carbons electron-rich. Consequently, the reactivity of the aromatic ring towards electrophilic substitution increases. For instance, the nitration of anisole is about 10,000 times faster than the nitration of benzene. The electron-donating effect of the methoxy group in anisole activates the ortho and para positions on the ring and stabilizes the corresponding...
