Study on the metabolites of 1α,25-dihydroxyvitamin D4
摘要:
Three major metabolites of 1 alpha ,25-dihydroxyvitamin D-4 were isolated from the bile of rat and the structures were elucidated on the basis of spectral data and the periodate oxidative cleavage of the diol structures of the metabolites. One of the metabolites was the known calcitroic acid. Another two metabolites were isomers and identified as 9, 10-secoergosta-5,7,10(19)-triene-1 alpha ,3 beta ,24,25-tetrahydroxy-26-oic acid and 9,10-secoergosta-5,7,10(19)-triene-1 alpha ,3 beta ,24,25tetrahydroxy-28-oic acid. It was found that 1 alpha ,25-dihydroxyvitamin D-4 is metabolized in a similar manner in vivo to that of 1 alpha ,25-dihydroxyvitamin D-2 but differently from 1 alpha ,25-dihydroxyvitamin D-2.
