  Synthesis of putative metabolites of 1α,25-dihydroxy-2β-(3-hydroxypropoxy)vitamin D3 (ED-71)

  摘要：

  1 alpha,25-Dihydroxy-2 beta-(3-hydroxypropoxy)vitamin D-3 (ED-71), an analog of active vitamin D-3, 1 alpha,25-dihydroxyvitamin D-3 [1,25(OH)(2)D-3] is under phase III clinical trials in Japan for the treatment of osteoporosis and bone fracture prevention. Since ED-71 has a substituent at the 2 beta-position of the A-ring, it is recognized that the metabolic pathway of ED-71 might be more complicated than 1,25(OH)(2)D-3 because of metabolism at the 2 beta-position substituent in addition to the inherent metabolism of the side chain. To clarify the metabolism of hydroxypropoxy substituent of the 2 beta-positon and a combination of metabolism between side chain and 2 beta-positon, four putative metabolites of ED-71 have been prepared as authentic samples. The metabolites at the 2 beta-positon, the methyl ester derivative considered as an ester standard of the oxidized metabolite and the tetraol derivative as the truncated metabolite were synthesized from alpha-epoxide, a key intermediate of ED-71 synthesis. The combination metabolites between side chain and 2 beta-positon, the 24(S)- and 24(R)-pentaols were synthesized using Trost's convergent method. (c) 2006 Elsevier Inc. All rights reserved.

  The present invention provides a vitamin D derivative of the general formula (I): wherein A denotes a straight chain or branched chain alkylene group with 2 to 10 carbon atoms and R denotes SO3R1 in which R1 represents a hydrogen atom or a straight chain or branched chain alkyl group with 1 to 3 carbon atoms or COOR2 in which R2 represents a hydrogen atom or a straight chain or branched chain alkyl group with 1 to 3 carbon atoms; an intermediate compound for synthesis of the vitamin D derivative; and a pharmaceutical composition containing the vitamin D derivative as an active ingredient. The compound of the invention has affinity for a vitamin D receptor and a vitamin D binding protein, and is useful as a drug, such as a drug for treatment of diseases due to abnormal of calcium metabolism. The compound is considered to be a metabolite of a vitamin D derivative having a substituent at the 2&bgr;-position, especially, 2&bgr;-(3-hydroxypropoxy)-1&agr;,25-dihydroxyvitamin D3. This compound can advantageously be used as an authentic sample to identify the derivative.
