Some (piperidinomethylene)bis(phosphonic acid) derivatives were prepared and their activity to inhibit a rise in serum calcium induced by parathyroid hormone in thyroparathyroidectomised rats was evaluated. Several (4-alkylidene-, 4,4-dialkyl-, or 4-alkyl-4-halopiperidinomethylene)bis(phosphonic acid) derivatives showed considerable inhibitory activity. But compounds having aromatic and polar substituents
制备了一些(哌啶子基亚甲基)双(膦酸)衍生物,并评估了它们抑制甲状旁腺切除的大鼠的甲状旁腺激素诱导的血清钙升高的活性。几种(4-亚烷基-,4,4-二烷基-或4-烷基-4-卤代哌啶亚基)双(膦酸)衍生物表现出相当大的抑制活性。但是在哌啶环上具有芳族和极性取代基如叠氮基,羟基,氨基和酰胺基的化合物通常是无活性的。在这项研究中,两种4-亚烷基化合物(8a和8b)和4,4-环二烷基化合物(61)在静脉内或经口给药时均显示出强大的活性。
