The amidation reaction of carboxylicacid derivatives was developed using sulfur trioxide pyridinecomplex (SO3·py) as a commercially available and easily handled oxidant. This method could be applied to the reaction of various aromatic and aliphatic carboxylicacids, including optically active ones, with formamide derivatives to afford the corresponding amides in good to high yields.
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。

Treatment of allylic and benzylichalides with N,N-dimethylcarbamoyl(trimethyl)silane in the presence of tetrakis(triphenylphosphine)palladium(0) affords tertiary amides, which arise from the replacement of the halogen by the N,N-dimethylcarbamoyl group.
