Structure−Activity Relationship of Triazafluorenone Derivatives as Potent and Selective mGluR1 Antagonists
摘要:
SAR (structure -activity relationship) studies of triazafluorenone derivatives as potent mGIuR1 antagonists are described. The triazafluorenone derivatives are non-amino acid derivatives and noncompetitive mGluR1 antagonists that bind at a putative allosteric recognition site located within the seven-transmembrane domain of the receptor. These triazafluorenone derivatives are potent, selective, and systemically active mGluR1 antagonists. Compound 1n, for example, was a very potent mGIuR1 antagonist IC50 = 3 nM) and demonstrated full efficacy in various in vivo animal pain models.
The present invention provides a compound promoting osteogenesis. The present invention provides a compound having the following general formula (I)
wherein R1 is H or alkyl,
R2 is RaS-, RaO-, RaNH-, Ra(Rb)N- or cyclic amino, and
Ra and Rb are alkyl which may be substituted, cycloalkyl which may be substituted, or the like, or a pharmacologically acceptable salt thereof.
A cell-based assay was performed for the discovery of novel bone anabolicagents. Alkaline phosphatase (ALPase) activity of ST2 cells was utilized as an indicator of osteoblastic differentiation, and thienopyridine derivative 1 was identified as a hit compound. 3-Aminothieno[2,3-b]pyridine-2-carboxamide was confirmed to be a necessary core structure for the enhancement of ALPase activity, and then
进行了基于细胞的测定,以发现新型骨合成代谢剂。ST2细胞的碱性磷酸酶(ALPase)活性被用作成骨细胞分化的指标,噻吩并吡啶衍生物1被确定为命中化合物。确认3-氨基噻吩并[2,3- b ]吡啶-2-甲酰胺是增强ALPase活性的必要核心结构,然后对噻吩并吡啶环上的C4-取代基进行了优化。将环氨基引入噻吩并吡啶环的C4位提高了活性。特别地,在该新系列中,发现N-苯基-高哌嗪衍生物是ALPase的强增强剂。此外,3-氨基-4-(4-苯基-1,4-二氮杂-1-基)噻吩并[2,3-在6周内向卵巢切除(OVX)大鼠口服b ]吡啶-2-甲酰胺(15k)以评估其对面骨矿物质密度(aBMD)的影响,并且从10 mg / mg的剂量观察到aBMD有统计学上的显着改善公斤/天。
