制备方法与用途

生物活性

Lexacalcitol (KH1060) 是一种维生素 D 类似物,能够有效调节细胞生长和免疫反应。它可用于研究移植排斥反应、银屑病、癌症及自身免疫性疾病。

体外研究
  • Lexacalcitol 在人类组织细胞淋巴瘤细胞系 U937 中抑制细胞增殖的半数抑制浓度为 10⁻¹² M,比 1,25(OH)₂D₃ 活性高 14,000 倍。
  • Lexacalcitol 在 3×10⁻¹⁶ M 下可抑制白介素-1 引起的小鼠胸腺细胞增殖,在 5×10⁻¹⁵ M 下可抑制同种异体刺激小鼠脾淋巴细胞的增殖。
体内研究

Lexacalcitol(0.5 mg/kg/2 天,腹腔注射)与环孢素 A (CyA) 联合使用可以预防自发性糖尿病 NOD 小鼠同基因胰岛移植的自身免疫破坏。单次治疗 Lexacalcitol 或 CyA 未能显著抑制早期移植物失败,而联合治疗则可预防早期移植物失败并延缓自发性糖尿病 NOD 小鼠异基因胰岛的排斥反应。

动物模型 雌雄自发性糖尿病 NOD 小鼠
剂量 0.5 mg/kg/2 天
给药方式 腹腔注射
结果 单独使用 KH1060 或 CyA 并未显著抑制早期移植物失败,而联合用药则可预防早期移植物失败并延缓自发性糖尿病 NOD 小鼠异基因胰岛的排斥反应。

    名称:
    Contribution of several metabolites of the vitamin D analog 20-epi-22-oxa-24a,26a,27a-tri-homo-1,25-(OH)2 vitamin D3 (KH 1060) to the overall biological activity of KH1060 by a shared mechanism of action
    摘要:
    The synthetic 1,25-dihydroxyvitamin D-3 (1,25-(OH)(2)D-3) analog 20-epi-22-oxa-24a,26a,27a-trihomo-1,25-(OH)(2) vitamin D-3 (KH1060) is considerably more potent than its cognate hormone. The mechanism of action of KH1060 includes interaction with the vitamin D receptor(VDR). We previously showed that KH1060 increases VDR stability in ROS 17/2.8 osteoblastic cells by inducing a specific conformational change in the VDR. KH1060 is metabolized, both in vivo and in vitro, into several stable products. In the present study, we investigated whether these metabolites might contribute to the increased biological activity of KH1060. We found that the potencies of two of these metabolites, 24a-OH-KH1060 and 26-OH-KH 1060, were similar to that of 1,25-(OH),D, in inducing osteocalcin production by the osteoblast cell line ROS 17/2.8. This report further showed that these metabolites had the same effects as KH1060 on VDR: they increased VDR stability in ROS 17/2.8 cells, while limited proteolytic analysis revealed that they caused a conformational change in the VDR, resulting in an increased resistance against proteolytic cleavage. Furthermore, as shown in gel mobility shift assays, both compounds clearly induced VDR binding to vitamin D response elements. Together, these results show that the potent in vitro activity of KH1060 is not only directed by the effects on the VDR conformation/stabilization of the analog itself, but also by certain of its long-lived metabolites, and emphasizes the importance of detailed knowledge of the metabolism of synthetic hormonal analogs.
