Discovery of an N-(2-aminopyridin-4-ylmethyl)nicotinamide derivative: a potent and orally bioavailable NCX inhibitor
摘要:
Ca2+ overload in myocardial cells is responsible for arrhythmia. Sodium-calcium exchanger (NCX) inhibitors are more effective than sodium hydrogen exchanger (NHE) inhibitors with regard to modulation of Ca2+ overload, because NCX inhibitors can directly inhibit the influx of Ca2+ into cells. NCX is an attractive target for the treatment of heart failure and ischemia-reper-fusion. We have designed and synthesized a series of N-(2-aminopyridin-4-ylmethyl)nicotinamide derivatives, based on compound 5. We have discovered a novel NCX inhibitor (23h) with an IC50 value of 0.12 mu M against reverse NCX. The inhibitory activities of our NCX inhibitors against cytochrome P450 were also evaluated. The effects on heart failure and the pharmacokinetic profile of compound 23h are discussed. (c) 2005 Elsevier Ltd. All rights reserved.

An operationally simple and economical method for the direct alkylation of heteroaromaticbases employing readily available aldehydes as alkyl radical precursors and molecular oxygen as a reagent is presented. This simple transformation demonstrates a broad substrate scope with respect to aldehydes and nitrogen heterocycles, enabling the introduction of several medicinally important yet challenging

A new method for silver-catalyzed Minisci reactions usingSelectfluor as a mild oxidant is reported. Heteroarenes and quinones both participate in radical C–H alkylation and arylation from a variety of carboxylic and boronic acid radical precursors. Several oxidatively sensitive and highly reactive radical species are successful, providing structures that are challenging to access by other means.
A compound having the structure
useful for treating hypertension, Pulmonary Arterial Hypertension (PAH), congestive heart failure, conditions resulting from excessive water retention, cardiovascular disease, diabetes, oxidative stress, endothelial dysfunction, cirrhosis, pre-eclampsia, osteoporosis or nephropathy.
