bile acid

C-12 vs C-3 substituted bile salts: an example of the effects of substituent position and orientation on the self-assembly of steroid surfactant isomers

Biomolecule derivatives are transversally used in nanotechnology. Deciphering their aggregation behavior is a crucial issue for the rational design of functional materials. To this end, it is necessary to build libraries of selectively functionalized analogues and infer general rules. In this work we enrich the highly applicative oriented collection of steroid derivatives, by reporting a rare example of C-12 selectively modified bile salt. While nature often exploits such position to encode functions, it is unusual and not trivial to prepare similar analogues in the laboratory.

Synthesis of useful aromatic derivatives of bile acids through Click chemistry

Bile acids are a very important class of natural surfactants, showing
themselves and their derivatives as effective self-assembling materials. The morphology of bile acid derivative aggregates is strongly
dependant upon the substituents present both on the rigid steroid
backbone and on the side chain, making them suitable for applications in
nanochemistry, sensing and drug delivery.
