Paragraph 0023; 0024; 0025, (2016/10/27)
The invention discloses a synthesis method of a thienopyridine medical intermediate. The method takes malononitrile as the raw material to prepare the product by six-step reaction. The thienopyridine medical intermediate involved in the invention is 3-amino-4-(dimethylamino)thieno[2, 3-b]pyridine carboxamide. The invention adopts two brand new synthetic methods for preparation of 3-amino-4-(dimethylamino)thieno[2, 3-b]pyridine carboxamide from 2-chloro-4-(dimethylamino)nicotinonitrile, the method is simple and easy to operate, and the atom economy is high.

A cell-based assay was performed for the discovery of novel bone anabolic agents. 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 optimization of the C4-substituent on the thienopyridine ring was carried out. Introduction of cyclic amino groups to the C4-position of the thienopyridine ring improved the activity. Especially, N-phenyl-homopiperazine derivatives were found to be strong enhancers of ALPase among this new series. Furthermore, 3-amino-4-(4-phenyl-1,4-diazepan-1-yl)thieno[2,3-b]pyridine-2- carboxamide (15k) was orally administered to ovariectomized (OVX) rats over 6 weeks for evaluating the effects on areal bone mineral density (aBMD), and statistically significant improvements in aBMD were observed from the dosage of 10 mg/kg/day.
