Therapeutically active compounds of formula (I) or (II) wherein X is -O-, -CH2- or -C(O)-; Z is -CHR12- or a valence bond; Y is -CH2-, -C(O)-, CH(OR13)-, -O-, -S-; provided that in case Z is a valence bond, Y is not C(O); the dashed line representing an optional double bond in which case Z is -CR12- and Y is -CH2-, -C(O)- or -CH(OR10)- (in formula II) or -CH- (in formula I); R2 and R3 are independently H, lower alkyl, lower alkoxy, -NO2, halogen, -CF3, -OH, benzyloxy or a group of formula (IIIa). R1 is H, CN, halogen, -CONH2, -COOR15, CH2NR15R18, NHC(O)R5, NHCH2R5, NHR20, NR21R22, NHC(NH)NHCH3 or, in case the compound is of formula (II) wherein the optional double bond exists or in case R2 or R3 is benzyloxy or a group of formula (IIIa) or in case the pyridine ring of formula (I) or (II) is attached to the oxygen atom in 3-, 4- or 5-position, R1 can also be -NO2 or NR16R17; R4 is H, -NO2, CN, halogen, -CONH2, -COOR15, -CH2NR15R18, -NR16R17, NHC(O)R5 or -NHC(NH)NHCH3; R5 is alkyl substituted with 1-3 substituents selected from the group consisting of halogen, amino and hydroxy, or carboxyalkyl, in which the alkyl portion is optionally substituted with 1-3 substituents selected from the group consisting of halogen, amino and hydroxyl, -CHR6NR,R8 or one of the following groups: formula (IVa), (IVb), (IVc), (IVd), (IVe), and pharmaceutically acceptable salts and esters thereof. The compounds are potent inhibitors of Na+/Ca2+ exchange mechanism.
式(I)或(II)的治疗活性化合物,其中X为-O-,-CH2-或-C(O)-;Z为-CHR12-或一个价键;Y为-CH2-,-C(O)-,CH(OR13)-,-O-,-S-;条件是如果Z为一个价键,则Y不是C(O);虚线表示可选的双键,此时Z为-CR12-,Y为-CH2-,-C(O)-或-CH(OR10)-(在式(II)中)或-CH-(在式(I)中);R2和R3独立地为H,较低的烷基,较低的烷氧基,-NO2,卤素,-CF3,-OH,苄氧基或式(IIIa)的基团。R1为H,CN,卤素,-CONH2,-COOR15,CH2NR15R18,NHC(O)R5,NHCH2R5,NHR20,NR21R22,NHC(NH)NHCH3的基团,或者,如果化合物为式(II),其中存在可选的双键,或者如果R2或R3为苄氧基或式(IIIa)的基团,或者如果式(I)或(II)的吡啶环附着在3-,4-或5-位置的氧原子上,则R1也可以是-NO2或NR16R17;R4为H,-NO2,CN,卤素,-CONH2,-COOR15,-CH2NR15R18,-NR16R17,NHC(O)R5或-NHC(NH)NHCH3;R5为烷基,其上取代有1-3个取自卤素、氨基和羟基或羧基的取代基,其中烷基部分可选地取代有1-3个取自卤素、氨基和羟基的取代基,-CHR6NR,R8或以下所示的一个基团之一:式(IVa),(IVb),(IVc),(IVd),(IVe),以及其药用可接受的盐和酯。这些化合物是Na+/Ca2+交换机制的有效抑制剂。
