Description Following our earlier observations that curcumin and capsaicin are antilithogenic in mice and hamsters, attempts were now made to understand the manner in which these spice principles were acting. For this purpose, the hepatic biles of rats fed a control, lithogenic, and lithogenic diet supplemented with curcumin or capsaicin were subjected to gel filtration chromatography (sepharose-4B-Cl) and the LMW protein fractions were tested for their ability to influence cholesterol crystal growth in model bile. The LMW protein fraction from the lithogenic group bile shortened the nucleation time and increased the crystal growth rate and final crystal concentration. But with the LMW protein fractions from the biles of rats on the lithogenic group supplemented with curcumin or capsaicin, the nucleation times were prolonged and the crystal growth rates and final crystal concentrations were decreased. The LMW fractions were further purified into three different sugar specific proteins by affinity chromatography. A higher proportion of LMW proteins from the lithogenic group bile was bound to Con-A whereas higher proportions of LMW proteins from the groups fed with curcumin and capsaicin were respectively bound to wheat germ agglutinin and Helix pomatia lectin. The Con-A bound fraction obtained from the lithogenic group showed a pro-nucleating effect. In contrast, the WGA-bound fraction obtained from curcumin group or the Helix pomatia lectin bound fraction obtained from capsaicin group showed a potent antinucleating activity.
