摘要:
As a systemic metabolic disease caused by a variety of factors,osteoporosis is characterized by reduced bone mass,bone tissue microstructural degradation,and decreased bone mechanical properties,accompanied by bone fragility and fracture,which is a common risk of senile *** China,osteoporosis has become a common disease and has frequent morbidity,with the incidence trend on the *** have received much attention in this field as inhibitory bone resorption agents,and sodium olpadronate belongs to the third-generation *** experiment investigated the synthetic process and pharmacological activity of sodium *** 3-(N,N-dimethylamino)-propionitrile as the starting material,the synthesis process was improved to reduce cost with a total yield of 49.7%,which was 24.0%higher than that reported in the *** experiments showed that sodium olpadronate could be used to treat ***,toxicology experiments showed no obvious toxic side *** together,sodium olpadronate had very promising development prospects.
