The present invention relates to a medicine, particularly a medicine comprising a novel cyclohepta[b]pyridine-3-carbonylguanidine derivative having an inhibitory effect on an Na+/H+ exchanger (NHE). There is provided a cyclohepta[b]pyridine-3-carbonylguanidine derivative represented by Formula (1):
wherein R1 is a group selected from a sulfo group, a sulfoxy group, -OCONH-(CH2CH2O)n-SO3H and the following formulas:
R2 represents a halogen atom, a lower alkyl group or a lower alkoxy group; and n represents an integer from 1 to 10,
or a pharmaceutically acceptable salt thereof.
本发明涉及一种药物,特别是一种包含对 Na+/H+ 交换器(NHE)具有抑制作用的新型环庚基[b]
吡啶-3-羰基
胍衍
