    • Inhibitors of bone calcium resorption are administered to allow high doses of vitamin D compounds or mimetics to be given with the intent of treating non-calcium related diseases such as cancer, psoriasis, and autoimmune disease without the dangers of calcification of kidney, heart, and aorta. Inhibitors of bone calcium resorption include the bis-phosphonates, OPG (osteoprotegerin) or the soluble RANKL (receptor activator of NF-κB ligand) receptor known as sRANK (soluble RANK which is the protein expressed by the NF-κB gene), and function to block the availability of calcium from bone thereby preventing hypercalcemia and the resulting calcification of soft tissues. Thus, high doses of 1α,25-dihydroxyvitamin D3 (1,25-(OH)2D3), its analogs, prodrugs, or mimetics can be utilized with minimal risk to a patient. Specifically, alendronate is shown to block the bone calcium mobilization activity of both 1,25-(OH)2D3 and its very potent analog, 2-methylene -19-nor-(20S)-1α,25-dihydroxyvitamin D3.
    • 施用骨钙吸收抑制剂以允许给予高剂量的维生素D化合物或模拟物,其目的是治疗非钙相关疾病如癌症,牛皮癣和自身免疫性疾病,而不会引起肾,心脏和 主动脉。 骨钙吸收抑制剂包括称为sRANK(可溶性RANK,由NF-κB基因表达的蛋白质)的双膦酸盐,OPG(骨保护素)或可溶性RANKL(NF-κB配体的受体活化剂)受体)和功能 以阻止骨骼中钙的供应,从而防止高钙血症和软组织的钙化。 因此,高剂量的1α,25-二羟基维生素D 3 N(1,25-(OH)2 N 3),其类似物,前药 ,或者模拟物可以以最小的风险使用于患者。 具体地说,阿仑膦酸被显示阻断1,25-(OH)2 N 3 N 3及其非常有效的类似物2-亚甲基-19-二酮的骨钙动员活性, (20S)-1α,25-二羟基维生素D 3。
