    • The present invention relates to metformin glycinate salt and pharmaceutical compositions thereof for the treatment of diabetes mellitus. The method includes administration of the metformin glycinate salt by various routes selected from oral, intravenous injectable, intramuscular injectable, nasal, intraperitoneal, or sublingual, in order to achieve a reduction in blood glucose levels. The invention further relates to the synthesis of a new 1,1-dimethylbiguanide glycinate salt, called Metformin Glycinate. The resulting salt exhibits advantages over other metformin salts. These advantages are due, in the first place, to the fact that the glycine counterion exhibits hypoglycemic effects by itself. Moreover, the salt exhibits more rapid absorption, reaching higher plasma concentrations than those produced with metformin hydrochloride.
    • 本发明涉及二甲双胍甘氨酸盐及其药物组合物,用于治疗糖尿病。 该方法包括通过选自口服,静脉注射,肌内注射,鼻腔,腹膜内或舌下的各种途径施用二甲双胍甘氨酸盐,以实现血糖水平的降低。 本发明还涉及称为二甲双胍甘氨酸的新的1,1-二甲基双胍甘氨酸盐的合成。 所得盐显示出优于其他二甲双胍盐的优点。 这些优点首先归因于甘氨酸抗衡离子本身表现出低血糖作用。 此外,盐显示更快的吸收,达到比盐酸二甲双胍生产的那些更高的血浆浓度。

    • In a process for oxidizing a hydrocarbon to a corresponding hydroperoxide, alcohol, ketone, carboxylic acid or dicarboxylic acid, the hydrocarbon is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide of the general formula (I): wherein each of R1 and R2 is independently selected from hydrocarbyl and substituted hydrocarbyl radicals having 1 to 20 carbon atoms, or from the groups SO3H, NH2, OH and NO2, or from the atoms H, F, Cl, Br and I provided that R1 and R2 can be linked to one another via a covalent bond; each of Q1 and Q2 is independently selected from C, CH, N and CR3; each of X and Z is independently selected from C, S, CH2, N, P and elements of Group 4 of the Periodic Table; Y is O or OH; k is 0, 1, or 2; 1 is 0, 1, or 2; m is 1 to 3, and R3 can be any of the entities listed for R1. The contacting produces an effluent comprising an oxidized hydrocarbon product and unreacted imide catalyst of said formula (I) and the effluent is treated with a solid sorbent to remove at least part of the unreacted imide catalyst and produce a treated effluent comprising said oxidized hydrocarbon product. The organic phase can then be recovered.
    • 在将烃氧化成相应的氢过氧化物,醇,酮,羧酸或二羧酸的方法中,烃在含有通式(I)的环状酰亚胺的催化剂存在下与含氧气体接触: 其中R 1和R 2各自独立地选自具有1至20个碳原子的烃基和取代的烃基,或者来自SO 3 H,NH 2,OH和NO 2基团,或者从原子H,F,Cl,Br和I 并且R 2可以通过共价键彼此连接; Q1和Q2中的每一个独立地选自C,CH,N和CR 3; X和Z各自独立地选自C,S,CH 2,N,P和元素周期表第4族的元素; Y为O或OH; k为0,1或2; 1是0,1或2; m为1至3,R3可为R1列出的任何实体。 接触产生包含氧化烃产物和所述式(I)的未反应酰亚胺催化剂的流出物,并且用固体吸附剂处理流出物以除去至少部分未反应的酰亚胺催化剂并产生包含所述氧化烃产物的经处理的流出物。 然后可以回收有机相。
