  • Noncalcemic, Antiproliferative, Transcriptionally Active, 24-Fluorinated Hybrid Analogues of the Hormone 1α,25-Dihydroxyvitamin D<sub>3</sub>. Synthesis and Preliminary Biological Evaluation
    作者:Gary H. Posner、Jae Kyoo Lee、Qiang Wang、Sara Peleg、Martin Burke、Henry Brem、Patrick Dolan、Thomas W. Kensler

    Four new hybrid analogues of 1 alpha,25-dihydroxyvitamin D-3 (1) have been synthesized in a convergent manner by joining A-ring and C,D-ring fragments. Each hybrid analogue, having a noncalcemic 1-hydroxymethyl group and a potentiating 16-ene 24,24-difluorinated C,D-ring side chain, was designed to be lipophilic and inert toward 24-hydroxylase enzyme catabolism. Each hybrid analogue with 1 beta,3 alpha-substituent stereochemistry (i.e., analogues 3b and 4b) showed a pharmacologically desirable combination of in vitro high antiproliferative activity in two different cell lines and high transcriptional activity with also low calcemic activity in vivo.
  • Conformationally Restricted Hybrid Analogues of the Hormone 1α,25-Dihydroxyvitamin D3: Design, Synthesis, and Biological Evaluation

    Four new conformationally restricted hybrid analogues of the hormone 1 alpha -25-dihydroxyvitamin D(3) (1,25D3) have been synthesized in a convergent manner by combining enantiomerically pure C,D-ring ketones (-)-15 and (-)-17 with racemic 1-hydroxymethyl A-ring phosphine oxide (+/-)-18. Parent hybrid analogue 6, which combines the calcemia-inactivating la-hydroxymethyl A-ring modification with the antiproliferation-activating 20-epi-22-oxa-25-hydroxydiethyl C,D-ring side chain modification, is comparable in potency to 1,25D3 at the low nM level in inhibiting proliferation in a wide assortment of malignant cell lines in vitro with extremely low calcemic activity in vivo. Surprisingly, both conformationally restricted analogues of 6 (8b and 9b), which incorporate rigidifying units at their 25-hydroxyl side chain termini, retained the desirable antiproliferative, transcriptional. and calcemic activities of the parent compound.

  • New vitamin D3 derivatives with unexpected antiproliferative activity: 1-(hydroxymethyl)-25-hydroxyvitamin D3 homologs

    Surprisingly, both of the synthetic 1-(hydroxymethyl)-25-hydroxyvitamin D3 diastereomers (-)-2 and (+)-3 retained the antiproliferative activity of natural calcitriol in murine keratinocytes. Preliminary studies indicated, however, that both of these synthetic diastereomers were less than 0.1% as effective as calcitriol for binding to the 1,25-(OH)2-D3 receptor and that they were less than 0.1% as
    令人惊讶地,合成的1-(羟甲基)-25-羟基维生素D3非对映异构体(-)-2和(+)-3均保留了天然骨化三醇在鼠角质形成细胞中的抗增殖活性。然而,初步研究表明,这两种合成的非对映异构体与钙三醇结合1,25-(OH)2-D3受体的有效性均低于钙三醇,而钙结合蛋白的效价均低于钙三醇的0.1%。器官培养的胚胎十二指肠中的-D28K诱导。1-(羟甲基)-25-羟基维生素D3同源物(-)-2和(+)-3通过对映体纯的C,D环酮12与高度对映体富集的A环膦氧化物(- )-11a和(+)-11b。从3-溴-2-吡喃酮和丙烯醛的热[2 + 4]环加成反应开始制备这些A环螯合物。

    dichloride promotes highly regioselective and stereoselective Diels-Alder cycloaddition between 3-bromo-2-pyrone, prepared in a new way, and unactivated terminal alkene 4-(tert-butyldimethylsiloxy)-1-butene. The conjugate base of A-ring allylic phosphine oxide 20 adds chemospecifically to the C-8 keto group of some C-8,C-24-diketones to form directly metabolically resistant 24-oxo analogs of 1alpha,25-dihydroxyvitamin
