Neladenoson Bialanate Hydrochloride: A Prodrug of a Partial Adenosine A1 Receptor Agonist for the Chronic Treatment of Heart Diseases

Adenosine is known to be released under a variety of physiological and pathophysiological conditions to facilitate the protection and regeneration of injured ischemic tissues. The activation of myocardial adenosine A1 receptors (A1Rs) has been shown to inhibit myocardial pathologies associated with ischemia and reperfusion injury, suggesting several options for new cardiovascular therapies. When full A1R agonists are used, the desired protective and regenerative cardiovascular effects are usually overshadowed by unintended pharmacological effects such as induction of bradycardia, atrioventricular (AV) blocks, and sedation. These unwanted effects can be overcome by using partial A1R agonists. Starting from previously reported capadenoson we evaluated options to tailor A1R agonists to a specific partiality range, thereby optimizing the therapeutic window. This led to the identification of the potent and selective agonist neladenoson, which shows the desired partial response on the A1R, resulting in cardioprotection without sedative effects or cardiac AV blocks. To circumvent solubility and formulation issues for neladenoson, a prodrug approach was pursued. The dipeptide ester neladenoson bialanate hydrochloride showed significantly improved solubility and exposure after oral administration. Neladenoson bialanate hydrochloride is currently being evaluated in clinical trials for the treatment of heart failure.

NOVEL SYNTHESIS OF PYRIDIN-2(1H)-THIONES AND THIENO-PYRIDINES: REACTION OF ETHOXYMETHYLENES WITH ACTIVATED NITRILES

Ethoxymethylenes of benzoylacetonitrile, acetylacetone, benzoylacetone and ethyl acetoacetate reacts with cyanothioacetamide to give the corresponding 3-cyano-2(1H)-pyridinthione derivatives, which can be alkylated and cyclised into the corresponding thienopyridine derivatives.Key words: Activated nitriles, α-cyanothioacetamide, pyridine-2-(1H)-thiones, thienopyridines.
