The palladium-catalysed direct arylation of methyl 2-furoate with aryl bromides was studied. The use of KOAc as the base, dimethylacetamide (DMAc) as the solvent and Pd(OAc)2 as the catalyst was found to give 5-arylfurans regioselectively and without decarboxylation. These methyl 5-aryl-2-furoates gave 2,5-diarylfurans by decarboxylative coupling by using Pd(OAc)2 as the catalyst. Methyl 2-furoate thus represents a convenient alternative substrate to furan for the synthesis of mono- or poly-arylated furans.

A pair of chemical isomeric structures of N-acylhydrazone compounds I and II were designed and synthesized. The reaction was carried out with high diastereoselectivity to obtain one configurational isomer in excellent yields. The exact configuration and conformation of IIa and IIe were confirmed by the X-ray single crystal diffraction. The antitumor bioassay revealed that some compounds exhibited excellent activity against the selected cancer cell lines. In particular, IIf (IC50 = 16.4 μM) was better than doxorubicin (IC50 = 53.3 μM) against human promyelocytic leukemic cells (HL-60). Their toxicities were predicted in silico. The results showed that compounds II were safe and eligible to be development candidates. IIf showed great promise as a novel lead compound for further anticancer discovery.
Synthesis of heterocycles from arylation products of unsaturated compounds: XVIII. 5-Arylfuran-2-carboxylic acids and their application in the synthesis of 1,2,4-thiadiazole, 1,3,4-oxadiazole, and [1,2,4]triazolo[3,4-b][1,3,4] thiadiazole derivatives

A series of (5-arylfuran-2-ylcarbonyl)guanidines was synthesized and evaluated for the NHE-1 inhibitory activity and cardiprotective efficacy against ischemia-reperfusion injury. Starting with (5-phenylfuran-2-ylcarbonyl) guanidine 47 with a moderate inhibitory effect on NHE-1, the compounds with various substituents at the phenyl ring were investigated with the aim to optimize the potency. In this study, the 2,5-disubstituted compounds appeared to have better activities than the other analogues, and the 2-methoxy-5- chlorophenyl compound 85 was found as a potent inhibitor of NHE-1 (IC 50 = 0.081 μM). Furthermore, 85 showed a marked reduction of infarct size in the rat myocardial infarction model in vivo and significant improvement of cardiac contractile function in the isolated rat heart ischemia model in vitro.

Page/Page column 12, (2010/02/12)
The present invention relates to furancarbonylguanidine derivatives, a preparation method thereof and a pharmaceutical composition comprising the same. Furancarbonylguanidine derivatives of the present invention inhibit NHE-1 (sodium-hydrogen exchanger isoform 1), which helps recovery of heart function damaged from ischemia/ reperfusion and decreases myocardial infarction rate, indicating that they have protective effect on myocardial cells. Thus, furancarbonylguanidine derivatives of the present invention can be ef-fectively used for the prevention and the treatment of ischemic heart diseases such as myocardial infarction, arrhythmia, angina pectoris, etc, and also a promising candidate for a heart protecting agent applied to reperfusion therapy including thrombolytics or cardiac surgery including coronary artery bypass graft, percutaneous transluminal coronary angioplasty, etc.
