The present invention relates to a class of compounds useful in the treatment of congestive heart failure by increasing the contractility of a heart, a heart muscle or cells of a heart muscle. Moreover, the present invention relates to methods of producing a computer readable database containing representations of specific compounds of the present invention which interact with a specific binding pocket of Gβγ. The compounds or a pharmaceutically acceptable salt or ester thereof for use as a medicine of the invention are characterised by the following formula (I):A-L-B wherein A and B, which may be the same or different are represented by the following group (II)
wherein X represents -CONR3-, -NR3CO-, or -NR3COCH=CH-; L represents a single bond, an oxygen atom, a sulfur atom, a CR5R6 group or a NR5 group wherein R5 and R6 are selected from a hydrogen atom, an alkyl group and a halogen atom and R1 and R2 are defined as herein.
本发明涉及一类通过增强心脏、心肌或心肌细胞的收缩力来治疗充血性心力衰竭的化合物。此外,本发明还涉及制作计算机可读数据库的方法,该数据库包含与 Gβγ 的特定结合口袋相互作用的本发明特定化合物的表示。用作本发明药物的化合物或其药学上可接受的盐或酯的特征为下式(I):A-L-B 其中A和B可以相同或不同,由下式(II)表示
其中 X 代表-CONR3-、-NR3CO-或-NR3COCH=CH-; L 代表单键、氧原子、
硫原子、CR5R6 基团或 NR5 基团,其中 R5 和 R6 选自氢原子、烷基和卤素原子,R1 和 R2 的定义与本文相同。
