Reference of 70724-23-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 70724-23-1, 1-Chloro-6,7-dimethoxyphthalazine, introducing its new discovery.
Cardiac stimulant 1-(3- or 4-substituted piperidino)phthalazines
1-(3- or 4-substituted piperidino)phthalazines of the formula wherein R is C1-6 alkyl; Y is a 3- or 4-position substituent and is -X-(CHR1)m-Z wherein R1 is hydrogen or C1-6 alkyl; m is 1 or 2; X is oxygen or a direct link provided that when m is 1, X is a direct link; and Z is -N(R2)COR3, -N(R2)COOR3, -N(R2)SO2R3, -N(R2)SO2NR4R5, -N(R2)SOR3, -N(R2)CONR4R5 or -OCONR4R5, wherein R2 and R5 are each independently hydrogen or C1-6 alkyl; R3 is C1-6 alkyl, phenethyl, benzyl, C3-7 cycloalkyl, phenyl or pyridyl; R4 is hydrogen or R3; provided that when X is a direct link, R3 or R4 is C3-7 cycloalkyl; the pharmaceutically acceptable acid addition salts thereof; processes for their preparation; and their use as cardiac stimulants and phosphodiesterase inhibitors
