Design, synthesis and biological evaluation of nitric oxide releasing derivatives of dapagliflozin as potential anti-diabetic and anti-thrombotic agents

The cardiovascular complications were highly prevalent in type 2 diabetes mellitus (T2DM), even at the early stage of T2DM or the state of intensive glycemic control. Therefore, there is an urgent need for the intervention of cardiovascular complications in T2DM. Herein, the new hybrids of NO donor and SGLT2 inhibitor were design to achieve dual effects of anti-hyperglycemic and anti-thrombosis. As expected, the preferred hybrid 2 exhibited moderate SGLT2 inhibitory effects and anti-platelet aggregation activities, and its anti-platelet effect mediated by NO was also confirmed in the presence of NO scavenger. Moreover, compound 2 revealed significantly hypoglycemic effects and excretion of urinary glucose during an oral glucose tolerance test in mice. Potent and multifunctional hybrid, such as compound 2, is expected as a potential candidate for the intervention of cardiovascular complications in T2DM.

A reach geleg only preparation method

The invention relates to a preparation method for Dapagliflozin. The preparation method comprises the following steps that a compound 2 and phenetole are mixed to obtain a mixture, and then the mixture is dropped into a suspended aluminum trichloride solution, so that the content of generated ortho isomer impurities is smaller than 1 percent; a compound 4 in the preparation method is firstly reacted with butyl lithium to generate a compound 5 in the following formula; then the compound 5 is reacted with a compound 1, so that generation of sulphonate type genetic toxic impurities is avoided; therefore the utilization rate of raw materials is increased to a certain extent, the problem of complicated post-treatment is avoided, and the purity and the yield of products are improved. According to the preparation method, a compound 6 is reduced by using hydroboron and sulfuric acid, so that the reduction reaction and deprotection can be simultaneously carried out, and the pollution is greatly alleviated. The raw materials and the reagents which are adopted in the preparation method are relatively cheap and low in cost; meanwhile, the reaction conditions of the whole preparation process are mild, and the operation is simple and safe; industrial production can be conveniently realized.
