In a line of research focused on the design, synthesis and development of new bile acid-based compounds, the physico-chemical profile of the molecules must be thoroughly explored and analyzed. In this scenario, a fast and reliable information on the critical micellar concentration (CMC) of specific compounds through a profitable chromatographic parameter can be of aid to rationally direct the synthesis...
The microbial 7α-OH epimerisation of cholic, chenodeoxycholic, and 12-ketochenodeoxycholic acids (7α-OH bile acids) with Xanthomonas maltophilia CBS 827.97 to corresponding 7β-OH derivatives with scarcity of oxygen is described. With normal pressure of oxygen the 7-OH oxidation products are obtained. No biotransformations are achieved in anaerobic conditions. The microbial 7α-OH epimerisation is achieved...
