3α-Hydr­oxy-N-(3-hydroxy­prop­yl)-5β-cholan-24-amide

The title compound, C(27)H(47)NO(3), is a (3-hydroxy-prop-yl)amide derivative of naturally occurring enanti-opure lithocholic acid (3α-hydr-oxy-5β-cholan-24-oic acid). The mol-ecule contains four fused rings: three six-membered rings in chair conformations and one five-membered ring in a half-chair form. The two terminal six-membered rings are cis-fused, while other rings are trans-fused. The s...

Effect of sodium salts of 3α,12α-dihydroxy-7-oxo-5β-cholanoic and 3,7,12-trioxo-5β-cholanoic acids on verapamil hydrochloride in biophysical–chemical model experiments

It is known that certain bile acids have a promotive effect on the action of some drugs. Special attention is paid to bile acids having oxo groups instead of OH groups in the steroid skeleton of their molecule, since these derivatives have a lower hemolytic potential (membrane toxicity). This study examined the effects of sodium salts of 3α,12α-dihydroxy-7-oxo-5β-cholanoic acid (7-oC) and 3,7,1...

Comparison of Solubilization Capacity of Resveratrol in Sodium 3α,12α-Dihydroxy-7-oxo-5β-cholanoate and Sodium Dodecyl Sulfate

In this study we investigated resveratrol (trans-3,5,4'-trihydroxystilbene) solubilization with sodium 3α,12 α-dihydroxy-7-oxo-5 β-cholanoate (S7-OD) and sodium dodecyl sulfate (SDS). The investigation was aimed at determining whether large spherical micelles (SDS) or small longitudinal micelles (S7-OD) are more convenient for incorporation of resveratrol. Also, we studied resveratrol behavior ...
