Vascular prostaglandin synthesis: the early days.
Journal Title: Pharmacological Reports - Year 2006, Vol 58, Issue 0
Abstract
Prostacyclin (PGI(2)) and thromboxane (TxA(2)) labile cyclooxygenase (COX) products via PGH(2) were identified in biological fluids by the ingenious application of the principle of parallel pharmacological assays developed by John Vane. Either organ perfusates or circulating blood superfuse bioassay tissues arranged in a cascade. Tissues were selected based on specificity of responses to targeted eicosanoids. Additionally, PGI(2) inhibited platelet aggregation, a finding that led to discovery of its critical anti-thrombotic activity at the blood-endothelial interface. The biological activities of PGI(2) and TxA(2) were the fingerprints for tracking their isolation and ultimate chemical identification. These studies were responsible for opening the modern era of vascular biology that has facilitated the development of a rational approach to the treatment of diabetic and hypertensive complications involving the arterial circulation.

Comparison of cardioprotective effects of salvianolic acid B and benazepril on large myocardial infarction in rats.
In the present study, we compared cardioprotective effects of salvianolic acid B (Sal B) and the angiotension-converting enzyme inhibitor, benazepril, in rats with large myocardial infarction (MI). The large MI was produ...
Regulation of endothelial prostacyclin synthesis by Protease-activated receptors: mechanisms and significance.
The cellular actions of serine proteases are mediated through activation of a novel family of four G protein-coupled receptors known as protease-activated receptors (PARs). PARs are emerging as important modulators of di...
Effects 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...
9-Methyl-beta-carboline has restorative effects in an animal model of Parkinson's disease.
In a previous study, a primary culture of midbrain cells was exposed to 9-methyl-beta-carboline for 48 h, which caused an increase in the number of tyrosine hydroxylase-positive cells. Quantitative RT-PCR revealed increa...
Proline-linked nitrosoureas as prolidase-convertible prodrugs in human breast cancer cells.
A number of novel proline-linked nitrosoureas (1-4) were synthesized and examined for cytotoxicity and influence on DNA and collagen biosynthesis in MDA-MB-231 and MCF-7 human breast cancer cells. Evaluation of the cytot...
