This invention provides compounds for use as positive inotropic agents, bronchodilators, vasodilators and anticoagulants of the formula:
or a pharmaceutically acceptable salt thereof, wherein
R, is hydrogen, C1-C4 alkyl, or chloro;
R2 and R3 are independently hydrogen, C1-C4 alkyl, C1-C4 alkoxy, allyloxy, C1-C4 alkylthio, C1-C4 alkylsulfinyl, C1-C4 alkylsulfonyl, hydroxy, halo, cyano, nitro, amino, mono- or di-(C1-C4 alkyl)amino, trifluoromethyl, or C1-C4 alkoxy substituted with a group Z-Q-, wherein Q is oxygen, sulfur, sulfinyl, sulfonyl, or a bond, and Z is a C1-C4 alkyl, phenyl, or phenyl substituted with halo, C1-C4 alkyl, C1-C4 alkoxy, hydroxy, nitro, amino, C1-C4 alkylthio, C1-C4 alkylsulfinyl, or C1-C4 alkylsulfonyl; and
R4 is hydrogen, C1-C4 alkyl, or C1-C4 alkoxy; with the provisions that:
a) if R, and two of R2, R3, and R4 are all hydrogen, the other of R2, R3, and R4 is not hydrogen, halo, hydroxy, nitro, amino, di-(C,-C2 alkyl)amino, or C1-C2 alkoxy;
b) if R, and one of R2, R3 and R4 are both hydrogen, and one of R2, R3 and R4 is C1-C2 alkoxy, the other of R2, R3 and R4 is not hydroxy or C1-C2 alkoxy;
c) if R, is chloro and two of R2, R3, and R4 are all hydrogen, the other of R2, R3, and R4 is not hydrogen, halo, C1-C2 alkyl, or nitro; and
d) if R, is chloro and R4 is hydrogen, R2 and R3 may not both be nitro.
这项发明提供了以下公式的化合物,用作正性肌力药物、支气管扩张剂、血管扩张剂和抗凝剂,或其药学上可接受的盐:其中R是氢、C1-C4烷基或氯;R2和R3独立地是氢、C1-C4烷基、C1-C4烷氧基、烯丙氧基、C1-C4烷硫基、C1-C4烷基亚砜基、C1-C4烷基磺酰基、羟基、卤素、氰基、硝基、氨基、单-或双-(C1-C4烷基)氨基、三氟甲基或C1-C4烷氧基取代的Z-Q-基团,其中Q是氧、硫、亚砜基、磺酰基或键,Z是C1-C4烷基、苯基或取代有卤素、C1-C4烷氧基、羟基、硝基、氨基、C1-C4烷硫基、C1-C4烷基亚砜基或C1-C4烷基磺酰基的苯基;和R4是氢、C1-C4烷基或C1-C4烷氧基;但需满足以下条件:a)如果R和R2、R3和R4中的两个都是氢,则R2、R3和R4中的另一个不是氢、卤素、羟基、硝基、氨基、双-(C1-C2烷基)氨基或C1-C2烷氧基;b)如果R和R2、R3和R4中的一个都是氢,而R2、R3和R4中的一个是C1-C2烷氧基,则R2、R3和R4中的另一个不是羟基或C1-C2烷氧基;c)如果R是氯,而R2、R3和R4中有两个都是氢,则R2、R3和R4中的另一个不是氢、卤素、C1-C2烷基或硝基;d)如果R是氯,而R4是氢,则R2和R3不能同时为硝基。
