化学性质

白色固体。乙醇中最大紫外吸收波长为265 nm。

用途

抗牛皮癣、角化症药物,用于治疗牛皮癣、鱼鳞癣、掌跖脓疱病及角化症等。

生产方法
  1. 将889.5 mg化合物(Ⅰ)溶解于30 ml二甲亚砜中,加入从0.5 g钾制得的叔丁醇钾,在氩气保护下于20℃反应30分钟。倾入冰水,用乙醚萃取。提取液用水洗、干燥后浓缩。
  2. 残余物溶于乙醚,在-10℃或以下滴加到硼氢化钙和氯化钙的甲醇溶液中,并在-10℃搅拌1小时。用乙酸水溶液破坏过量的硼氢化钙,再浓缩。残余物溶于二氯甲烷后提取,用水洗、干燥并浓缩。
  3. 残余物溶于二氯甲烷,在室温下分批加入化合物(Ⅱ)。加毕,在室温搅拌1小时。蒸出溶剂,残余物经硅胶层析,以1%甲醇的氯仿溶液洗脱,得400.35 mg化合物(Ⅲ)。
  4. 将400.35 mg化合物(Ⅲ)溶解于氯仿中,加入间氯过苯甲酸,在25℃搅拌40小时。反应液用碳酸钾水溶液和水洗、干燥后浓缩。残余物经硅胶层析,以1%甲醇的氯仿溶液洗脱,得170.6 mg化合物(Ⅳ)。
  5. 将83.0 mg化合物(Ⅳ)溶解于干燥四氢呋喃中,分批加入氢化铝锂,在温和回流下搅拌1小时。加硫酸钠以破坏过量的氢化铝锂。分离有机层、干燥后浓缩。残余物经Sephadex LH-20层析提纯,以氯仿-己烷(65:35体积比)洗脱,得到21.3 mg化合物(V)。
  6. 将21.3 mg化合物(V)溶解于乙醚中,在400 W高压汞灯照射下进行反应,并通过通入氩气搅拌。浓缩后残余物经Sephadex LH-20层析提纯,以氯仿-己烷(65:35体积比)洗脱,得到3.64 mg产物。

    Syntheses and differentiating action of vitamin D endoperoxides. Singlet oxygen adducts of vitamin D derivatives in human myeloid leukemia cells (HL-60)
    摘要:
    Singlet oxygen adducts of various vitamin D derivatives, 6,19-dihydro-6,19-epidioxyvitamin D (vitamin D endoperoxides, 2 and 2'), were chemically synthesized, and their biological activity in inducing differentiation of a human myeloid leukemia cell line (HL-60 cells) was examined. The potency of the endoperoxides derived from vitamin D derivatives possessing the 1 alpha-hydroxyl group such as 1 alpha, 25-dihydroxyvitamin D3 endoperoxides (2b and 2b') was markedly (10(-2)) diminished relative to the respective parent vitamin D compounds. In contrast, 25-hydroxyvitamin D3 endoperoxides [25-(OH)D3 endoperoxides, 2a and 2a'] and their analogues fluorinated at the 24- or 26- and 27-positions were 2.5-10 times more potent than 25-hydroxyvitamin D3 (1a) in spite of the absence of the conjugated triene structure typical of vitamin D compounds. The potency of these vitamin D endoperoxides (2 and 2'), especially those lacking the 1 alpha-hydroxyl group, in inducing differentiation of HL-60 cells was not correlated with their activity in binding to the cytosol receptor for 1 alpha, 25-dihydroxyvitamin D3 (1b). The binding efficiency to the receptor was relatively lower than the differentiating activity. To examine the action of vitamin D endoperoxides, carbon analogues of 25-(OH)D3 endoperoxides, two C-6 epimers of 25-hydroxy-6,19-dihydro-6,19-ethanovitamin D3 (6 and 6'), were synthesized. The carbon analogues (6 and 6') had no potential to induce differentiation of HL-60 cells. These results suggest that vitamin D endoperoxides (2 and 2') express their biological activity probably after being converted to some other compounds.
