Preparation method of important intermediate of levosimendan

The invention belongs to the field, of synthesis of intermediates and relates to (R)- 6 - (4 -aminophenyl) - 5 - methyl - 444455-dihydropyridazine - 3333337. acetamide N - (4 - obtained by hydrolyzing)-methylpropionyl, phenyl, acetamide, in N - (4 - (3 - (-propionyl phenyl) - 2 - acetamide as starting material) and then chemical resolution.) yields high-purity,methylpropionyl (R)- N - (4 - (3 - (phenyl) - 2 - acetamide.). The present invention is very suitable for industrial production) by chemically resolving the high yield; dimethylamino,methylpropionyl-methaneanoyl-benzenesulfonamido (R)- N - (4 - (3 - phenylacetamido) obtained by hydrolyzing the intermediates with formaldehyde) dimethylamine. yields a high yield, yields a high yield of intermediate. The present invention relates to a, process for, producing high-chiral purified p-methyl propionylphenyl phenylacetonitrile.

Synthesis and anti-congestive heart failure activity of novel levosimendan analogues

A series of levosimendan analogues were designed and synthesized, employing the Friedel-Crafts reaction, hydrolysis, and cyclization from the key intermediate compound R(-)-6-(4-aminophenyl)-5-methyl-4, 5-dihydro-3(2H)- pyridazinone, which was obtained from the starting material, acetanilide. These compounds, except 1b, exhibited potent anti-congestive heart failure activities, especially the compounds 1e and 1k, which showed more effective action than levosimendan.

Studies on agents with vasodilator and β-blocking activities. V. Synthesis and pharmacological activity of the optical isomers of TZC-5665

Synthesis of the four optical isomers of TZC-5665 (1), a candidate for the treatment of congestive heart failure, was achieved by the reaction of chiral diaminopyridazinone (2) with chiral glycidyl ether (3). The hypotensive and β-blocking activities of 1 and its optical isomers were examined when given intravenously into anesthetized rats. Furthermore these compounds were evaluated for inhibitory activity on cAMP phosphodiesterase III. Among the four optical isomers, R(A),S(B)-one (1c) possessed the essential activities of TZC-5665 (1).
