    • A biologically-active compound which includes an inorganic mixed metal cationic portion having anion exchange properties and an anionic portion containing a biologically-active anion. The mixed metal cationic portion can be an oxide, hydroxide, or both, and can be fully hydrated, partially hydrated, or not hydrated. The biologically-active anion can be, e.g., an antibiotic, an analgesic, an antimicrobial, a pharmaceutical, an antioxidant, or an agricultural chemical such as a herbicide or a pesticide. These biologically-active compounds can have controlled-release properties and can be produced by relatively simple processes, using for the cationic portion relatively common starting materials. These biologically-active compounds are useful, for example, in compositions to form pharmaceuticals, antioxidants, or herbicides, and can be incorporated into a polymeric material to form a shaped body, such as a plastic film which can be utilized to form bags for food storage or transportation. Also included are processes for making the biologically-active compounds.
    • 一种生物活性化合物,其包括具有阴离子交换性质的无机混合金属阳离子部分和含有生物活性阴离子的阴离子部分。 混合金属阳离子部分可以是氧化物,氢氧化物或两者,并且可以完全水合,部分水合或不水合。 生物活性阴离子可以是例如抗生素,止痛剂,抗微生物剂,药物,抗氧化剂或农药如除草剂或农药。 这些生物活性化合物可以具有控制释放性质,并且可以通过相对简单的方法制备,使用阳离子部分相对常见的起始材料。 这些生物活性化合物可用于例如形成药物,抗氧化剂或除草剂的组合物中,并且可以并入聚合物材料中以形成成型体,例如可用于形成食品袋的塑料膜 存储或运输。 还包括制备生物活性化合物的方法。
