Danielsson and Kazuno have shown that 5j8-ranol is an efficient precursor of cholic acid in bile fistula rats while 26-deoxy-5)S-ranol is not [134]. The mechanism of the side-chain degradation of 5 -ranol is not known but probably an oxidation of the 26-hydroxyl group to a carboxyl group followed by a /S-oxidation. [Pg.295]

Major bile salts in the bullfrog, Rana catesbiana, are 27-nor-5/ -cho-lestane-3a,7a,12a,24,26-pentol (5/5-ranol) and 3a,7a,12a-trihydroxy-5) -cho-lestanoic acid. Betsuki (181,182) has shown that 5j5-cholestane-3a,7a,12a-triol and 3a,7a,12a,24-tetrahydroxy-5)5-cholestanoic acid are converted into 5/5-ranol and 26-deoxy-5)5-ranol. The following sequence of reactions in the... [Pg.27]

Ranol sulfate is a major bile salt of the bullfrog, Rana catesheiana [39]. 5)8-Ranol was identified as (24/ )-27-nor-5/8-cholestane-3a,7a,12a,24,26-pentol by comparison with synthetic material [39,40], 5)8-Ranol sulfate also occurs in bile of various species of frogs [9,18,19]. [Pg.284]

In a thorough analysis of solvolyzed material from bullfrog bile. Noma et al. isolated 4 new Cjj bile alcohols along with 5a-ranol, 5)3-ranol, and 5a-cyprinol [41]. Comparison with synthetic samples showed that these were 4 diastereoisomers at C-5 and C-24 of 26-deoxyranol, 27-norcholestane-3a,7a,12a,24-tetrol [41]. The... [Pg.284]

Noma et al. found 2 keto bile alcohols in unconjugated form in bullfrog bile [42]. Their structures were determined as 24-dehydro-26-deoxy-5a-ranol and its 5 isomer by comparison with synthetic 3a,7a,12a-trihydroxy-27-nor-5a- and 5/8-choles-tan-24-ones, prepared from allocholic acid and chohc acid, respectively [41]. [Pg.285]

Nor-26-deoxy-5a- and 5j8-ranols, 26,27-dinor-5a- and 5j8-cholestane-3a,7a,12a,24-tetrols, were detected by gas-liquid chromatography-mass spectrometry as minor constituents in the bile of a few species of frogs [9]. [Pg.285]
