Structure–activity relationships indicate that the presence of a lipophilic amino acid side chain is fundamental to achieve good potencies. The l-Trp derivative (20, PCM126) was the most potent antagonist of the series disrupting EphA2–ephrinA1 interaction and blocking EphA2 phosphorylation in prostate cancer cells at low μM concentrations, thus being significantly more potent than LCA. Compound 20 is among

increasing importance in biomedical applications. In this work, we report the formation of injectable hydrogels from bile acid-amino acid conjugates. The hydrogelation ability was dependent on multiple factors such as the bile acid backbone, linkage between the bile acid and the aminoacid, and pH. We have shown that the gelation properties depend on multiple noncovalent interactions and on the balance
