Synthesis and testing of 2α-Modified 1α,25-Dihydroxyvitamin D3 analogues with a double side chain: marked cell differentiation activity
摘要:
The 2alpha-methyl-, 2alpha-(3-hydroxypropyl)-, and 2alpha-(3-hydroxypropoxy)-derivatives of the 'double side chain' analogue of 1alpha,25-dihydroxyvitamin D-3 were synthesized using Trost A-ring/CD-ring connective strategy. Regarding the requisite A-ring building blocks, a new, high yield and stereoselective route to the 2alpha-methyl compound starting from D-glucose was developed. All three new analogues showed potent HL-60 cancer cell differentiation activity. (C) 2002 Elsevier Science Ltd. All rights reserved.
