Abstract
The present invention relates to a novel indole and azaindole derivative and a preparation method and application thereof in medicines. Specifically, the present invention relates to an indole and azaindole derivative shown as the general formula (I) and a preparation method, a pharmaceutical composition containing the derivative, and application of the derivative as a therapeutic agent especially as a gastric acid secretion inhibition agent and potassium ion competitive acid blockers (P-CABs), wherein substituents in the general formula (I) are as defined in the specification.
Description
Technical field
The present invention relates to the new indoles of a class and azaindole analog derivative, its preparation method and the drug regimen containing this derivative and its as therapeutical agent particularly as the purposes of gastric acid secretion inhibitor and the competitive sour retarding agent (P-CABs) of potassium ion.
Background technology
Since 1988, be that the proton pump inhibitor of representative is used widely to treat peptide ulceration, reflux esophagitis and Zollinger-Eillison syndrome etc. clinically by gastric acid secretion inhibiting with omeprazole.Long-term clinical application finds, existing proton pump inhibitor also has limitation in pharmacokinetics, pharmacodynamics.As: administration time is on the impact of drug effect; Control of Nocturnal Gastric Acid Breakthrough onset is slow; Under acidic conditions unstable (needing to be mixed with Enteral formulations); To dependency of CYP450 enzyme (cause individual difference remarkable) etc.
The competitive sour retarding agent (Potassium-CompetitiveAcidBlockers, P-CABs) of potassium suppresses H competitively by direct, reversible process
+/ K
+k in-ATP enzyme
+and generation effect.Compared with traditional proton pump inhibitor, P-CABs has lipotropy, weakly alkaline, feature that dissociation constant is high and stable at low ph conditions.Under sour environment, P-CABs is with ionized form and H
+/ K
+-ATP enzyme combines, and stops H
+transport and acid are secreted in gastral cavity, raise pH value in stomach rapidly.Experimentation on animals and clinical study show: it is rapid that P-CABs possesses onset, in 1 hour, just can reach maximum hospital benefit; Plasma Concentration and qf oral administration dosage linear dependence, than being easier to the advantage reaching best acid suppression effect.
Although disclosed the competitive sour retarding agent of a series of potassium at present, but still need development structure type abundanter, the new compound may with better patent medicine character, through continuous effort, the present invention's design has the compound of the structure shown in general formula (I), and finds that the compounds exhibit with this class formation goes out excellent effect and effect.
