Glycocholic acid sodium is an orally active bile acid with anticancer activity, targeting against pump resistance-related and non-pump resistance-related pathways[1].
Glycocholic acid (GC) increases the cytotoxicity of epirubicin, significantly increases the intracellular accumulation of epirubicin in Caco-2 cells and the absorption of epirubicin in rat small intestine, and intensified epirubicin-induced apoptosis. Glycocholic acid and epirubicin significantly reduce mRNA expression levels of human intestinal MDR1, MDR-associated protein (MRP)1, and MRP2; downregulate the MDR1 promoter region; suppress the mRNA expression of Bcl-2; induce the mRNA expression of Bax; and significantly increase the Bax-to-Bcl-2 ratio and the mRNA levels of p53, caspase-9 and -3. A combination of anticancer drugs with Glycocholic acid can control MDR via a mechanism that involves modulating P-gp and MRPs as well as regulating apoptosis-related pathways[1].

Why is Glycocholic acid sodium salt better than deoxycholic acid sodium salt for the preparation of mixed micelle injections?
Food Sci Nutr 2019 Sep 27;7(11):3675-3680.PMID:31763016DOI:10.1002/fsn3.1224.
Classical mixed micelle systems make excellent parenteral drug carriers for lipophilic or poorly soluble drugs, but many formulations details are not fully understood and need further study. Thus, we constructed mixed micelle systems with lecithin and either Glycocholic acid sodium salt or deoxycholic acid sodium salt in order to investigate the differences between the bile salts. Vitamin K1, a lipid-soluble drug, was encapsulated in the mixed micelles, and the influence of bile salts on the quality and stability of the mixed micelle systems was analyzed. Both bile salts displayed similar profiles, and the amounts of bile salts used in formulating clear solutions did not differ. Mixed micelle systems formed from Glycocholic acid sodium were physically stable at low pH levels (5.5), whereas those formed from deoxycholic acid required higher pH (>8.5). High pH levels hurt active pharmaceutical ingredients that are prone to hydrolytic and oxidative degradation. Hence, when mixed micelle systems formed from deoxycholic acid sodium were sterilized, unexpected chemical unstability occurred. Therefore, we conclude that Glycocholic acid sodium salt is more suitable than deoxycholic acid sodium salt for the preparation of mixed micelle injections.
Potential tumor-promoting activity of bile acids in rat glandular stomach
Jpn J Cancer Res 1987 Jan;78(1):32-9.PMID:3102436doi
The potential tumor-promoting and -initiating activities of bile acids in the glandular stomach mucosa of F344 rats after administration by gastric intubation were studied. Taurocholic acid sodium salt at doses of 300 to 1200 mg/kg body weight and Glycocholic acid sodium salt at doses of 400 to 1200 mg/kg body weight induced up to 100-fold increases in ornithine decarboxylase activity with maxima after 4 hr and up to 10-fold increases in replicative DNA synthesis with maxima after 16-17 hr in the pyloric mucosa of the stomach. Taurodeoxycholic acid sodium salt, taurochenodeoxycholic acid sodium salt and glycocholic acid also induced high ornithine decarboxylase activity, and glycodeoxycholic acid sodium salt and glycochenodeoxycholic acid sodium salt caused slight induction of ornithine decarboxylase activity, but taurolithocholic acid sodium salt did not induce ornithine decarboxylase activity at all in the pyloric mucosa of the stomach. Glycocholic acid sodium salt did not induce unscheduled DNA synthesis in the pyloric mucosa of the stomach. The present results suggest that six bile acids, but not taurolithocholic acid sodium salt, have potential tumor-promoting activities in the pyloric mucosa of rat stomach and that Glycocholic acid sodium salt has no potential tumor-initiating activity in the pyloric mucosa of rat stomach.
