    • The disclosure provides, inter alia, novel bisphosphonate compounds and methods of making and using such compounds. In certain embodiments, compounds of the invention include bisphosphonates that are capable of selectively inhibiting one or more of farnesyl diphosphate synthase (FPPS), geranylgeranyl diphosphate synthase (GGPPS), and decaprenyl pyrophosphate synthase (DPPS). In preferred embodiments, compounds of the invention are capable of selectively inhibiting two or more of FPPS, GGPPS, and DPPS. In embodiments, compounds and methods of the invention demonstrate superior activity levels, such as in the anti-cancer context, immunostimulation context, and other contexts, which in several cases exceed the activity levels of previous generation bisphosphonate drugs by orders of magnitude. In embodiments, the invention provides compounds and methods in connection with research and therapeutic applications, e.g., for tumor or cancer cell growth inhibition, activation of gammadelta T cells, inhibition of certain enzymes related to the mevalonate metabolic pathway, bone resorption diseases, cancer, immune disorders, immunotherapy, and infectious diseases.

    • Present invention discloses an improved and commercial process for the preparation of ibandronic acid or its monosodium salt. According to the process 3-N-methylaminopropionitrile is reacted with n-pentylbromide to get the tertiary amine of formula-II. Hydrolysis of the nitrile compound of formula-II with hydrochloric acid gave the b-alanine derivative of formula-X. Bis-phosphonylation of the acid compound of formula-X with phorphorous trichloride and phosphorous acid, followed by water hydrolysis gave aqueous ibandronic acid. Treatment of this with sodium hydroxide, followed by dilution of the aqueous solution with methanol gave ibandronate monosodium of formula-Ia as white crystalline solid. Present process utilizes simple raw materials and avoids the column chromatography technique used in the prior art process for isolation of ibandronic acid. Overall yield of ibandronate is more than 60% from the nitrile intermediate of formula-II. Ibandronate is widely used as bone resorption inhibitor.
    • 本发明公开了用于制备伊班膦酸或其单钠盐的改进和商业化方法。 根据方法,将3-N-甲基氨基丙腈与正戊基溴反应得到式II的叔胺。 用盐酸水解式II的腈化合物得到式-X的β-丙氨酸衍生物。 将式-X的酸化合物与无色三氯化磷和亚磷酸二膦酰化,随后进行水解,得到伊班膦酸水溶液。 用氢氧化钠处理,然后用甲醇稀释水溶液,得到式Ia的伊班膦酸钠单钠为白色结晶固体。 本发明方法使用简单的原料,并避免了用于分离伊班膦酸的现有技术方法中使用的柱色谱技术。 伊班膦酸钠的总收率高于式Ⅱ的腈中间体的60%以上。 伊班膦酸盐被广泛用作骨吸收抑制剂。
