Discovery of Selective Phosphodiesterase 1 Inhibitors with Memory Enhancing Properties

In this study, published in the Journal of Medicinal Chemistry, Dart Neuroscience identified a series of selective PDE1 inhibitors with favorable pharmacokinetic properties and brain penetration. CorDynamics supported the program by conducting in vivo cardiovascular safety assessments to evaluate potential hERG-mediated QT interval effects.

Subcutaneous Therapy for Portal Hypertension: PHIN-214, A Partial Vasopressin Receptor 1A Agonist

Data for PharmaIN was published in Biomedicine and Pharmacotherapy, assessing the use of PHIN-214 as a novel therapeutic in the treatment of portal hypertension. Our labs used bile duct ligation in the rat along with continuous telemetry of portal venous pressure to support the potential of PHIN-214 as a novel drug candidate in this area.

Comprehensive Echocardiographic Assessment of Right Ventricle Function in a Pulmonary Arterial Hypertension Model

In preclinical studies, the monocrotaline (MCT) injury model in rats is widely used to evaluate drug efficacy for treating PAH. This protocol describes the echocardiographic evaluation of the RV in naïve and MCT-induced PAH rats.

Characterization of binding, functional activity, and contractile responses of the selective 5-HT1F receptor agonist lasmiditan

Data for Eli Lilly/CoLucid was published in the British Journal of Pharmacology that assessed the in vivo vascular effects of lasmitidan compared to sumatriptan. Sonomicrometry was used to determine carotid and coronary arterial diameter, along with vasoconstriction and vasodilation.

Preclinical Studies of a Kidney Safe Iodinated Contrast Agent

In an attempt to develop a contrast agent that is less damaging to the kidneys, we have studied the effects of adding a small amount of the substituted cyclodextrin, sulfobutyl-ether-β-cyclodextrin (SBECD), to iohexol in preclinical models of renal toxicity.

PM101: A Cyclodextrin-Based Intravenous Formulation of Amiodarone Devoid of Adverse Hemodynamic Effects

This study provides a useful model for the continued search for a safe and effective intravenous amiodarone formulation devoid of the hypotensive risk associated with the current commercial formulation.

Comparison of the Cardiac Electrophysiology and General Toxicology of Two Formulations of Intravenous Amiodarone

Intravenous amiodarone (AIV) must be administered slowly after dilution to avoid hypotension, which is due to the cosolvents polysorbate 80 and benzyl alcohol used in its formulation. PM101 is a formulation of amiodarone devoid of these cosolvents, which enables bolus administration. We evaluated any potential toxicity or exaggerated adverse cardiac electrophysiologic effects of PM101 compared with AIV and control.

The Hypotensive Effect of Intravenous Amiodarone is Sustained Throughout the Maintenance Infusion Period

The objective of the present study was to determine whether the maintenance dose of the conventional formulation of intravenous amiodarone was associated with sustained hypotension throughout the dosing period.

Advantages of the Perfused Isolated Heart for the Assessment of the Electrophysiologic and Hemodynamic Effects of Drug Candidates

This paradigm acts as a physiologically relevant bridge between purely in vitro assays and costly, resource-intensive whole-animal studies. The model has been used extensively in experimental cardiovascular investigations and it is a widely accepted surrogate for the study of human cardiac function.

A nephroprotective iodinated contrast agent with cardioprotective properties: A pilot study

Neurrow Pharmaceuticals conducted a pilot study examining the putative anti-ischemic effect of Captisol Enabled-iohexol in myocardial infarction. Early data are suggesting this formulation is superior to iohexol alone with regard to preservation of cardiomyocyte integrity and preservation of cardiac function.

Mesenchymal Stromal Cell-Derived Exosomes Improve Mitochondrial Health in Pulmonary Arterial Hypertension

We performed studies for United Therapeutics to determine whether the administration of mesenchymal stromal cell-derived exosomes could improve PAH in both mice and rats. Using both hypoxia alone and hypoxia/Sugen models, our data demonstrated improvements in both pulmonary hemodynamics and right ventricular hypertrophy after exosome administration.

Sotatercept (ACTRIIA-Fc) Rebalances BMP and Activin/TGF-β Signaling to Attenuate Pulmonary Hypertension

Acceleron Pharma enlisted CorDynamics to study the effects of RAP-011, a murine analog of Sotatercept, compared to sildenafil in both the monocrotaline and hypoxia-sugen models of pulmonary arterial hypertension. Note the large reductions in both mean pulmonary arterial pressure and right ventricular hypertrophy with RAP-011.

Effect of XEN-R0703 on Inducibility and Atrial Refractoriness in a Chronic Model of Atrial Fibrillation

We generated data for Xention that showed notable efficacy of XEN-R0703 with regard to increasing atrial refractoriness and reduction of atrial fibrillation inducibility in a chronic, conscious model of AF. XEN-R0703 also did not affect corrected QT interval, an indication of atrial vs. ventricular selectivity.

Lasmiditan and Sumatriptan Comparison of In Vivo Vascular Constriction and In Vitro Contraction of Human Arteries

Working with CoLucid Pharmaceuticals, CorDynamics studied the vascular properties of lasmitidan and sumatriptan in preclinical cardiovascular studies and compared these results with human isolated arteries. The lack of vasoconstrictive properties of lasmitidan may be a cardiovascular safety advantage compared to the triptans.

Investigation of Mechanism of Drug-Induced Cardiac Injury and Torsades de Pointes

In collaboration with Hoffman-La Roche, CorDynamics conducted studies to determine the molecular mechanism of an arrhythmia found during the course of routine toxicological assessments. The compound RO5657, a CCR5 antagonist, was discovered to have the rare liability of inducing torsades de pointes (polymorphic ventricular arrhythmia) in normal, healthy animals.

Pharmacological Characterization of KLYP961, A Dual Inhibitor of Inducible and Neuronal Nitric Oxide Synthases

CorDynamics collaborated with the Kalypsys study of KLYP961. KLYP961 represents an ideal tool with which to probe the physiological role of NO derived from iNOS and nNOS in human pain and inflammatory states. KLYP961 has minimal off-target activity, desirable drug like properties such as pharmacokinetic profile, CYP-450 and hERG activities. In addition, KLYP961 has efficacy in a range of pain/inflammation models both in rodents and non-human primates.

Monocrotaline Induced Pulmonary Arterial Hypertension

In collaboration with Corridor Pharmaceuticals, CorDynamics demonstrated the novel serotonin receptor antagonist C-122 prevents monocrotaline induced pulmonary arterial hypertension in rats in a paper published in the European Journal of Pharmacology. The authors hypothesized that interfering with serotonin function may reduce the vascular remodeling and hemodynamic changes that occur in this preclinical model.

A Small-Molecule Antagonist of HIF2a Is Efficacious in Preclinical Models of Renal Cell Carcinoma
