lipophilic aromaticgroup present in most literature inhibitors that typically occupies a hydrophobic back pocket of the protein active site. Despite not having this ubiquitous feature of many known RIPK1 inhibitors, we were able to obtain compounds with good potency, kinase selectivity, and pharmacokinetic properties in rats. The use of the lipophilic yet metabolically stable pentafluoroethyl group was critical
Osteoporosis and the like metabolic bone diseases have a high frequency of causing lumbago and the like pains and bone fracture, due to lowering of the bone strength caused by the reduction of bone mass. Accordingly, great concern has been directed toward the creation of a drug which can increase the bone mass and bone strength by controlling the whole bone metabolism.
The pharmaceutical composition or combination product of the invention comprising a non-living body-derived non-peptide osteoblast differentiation promoting compound and a bisphosphonate having a bone resorption inhibitory action is useful as a bone mass increasing inducer which can increase the bone mass and/or bone strength by controlling the bone metabolism.
The invention relates to isoxazolo-pyridazine compounds, in particular those of formula I as described above and to a pharmaceutically acceptable salts thereof, having affinity and selectivity for the GABA A α5 receptor binding site, their manufacture, pharmaceutical compositions containing them and their use as cognitive enhancers or for the treatment of cognitive disorders like Alzheimer's disease.
这项发明涉及异氧唑吡啶嗪化合物,特别是如上所述的式I化合物及其药用盐,具有亲和力和选择性结合到GABA A α5受体结合位点,其制备方法,含有它们的药物组合物以及它们作为认知增强剂或用于治疗认知障碍如阿尔茨海默病。
