Soft Matter. 2016 Jul 07;12(25):5590-9. doi: 10.1039/c6sm00719h. Epub 2016 Jun 02.

Here we represent the first example of the formation of mixed nanoscale associates, constructed from amphiphilic calixresorcinarenes and hydrophobic carboxylic acids including drugs. The amidoamino-calixresorcinarene self-associates effectively solubilize hydrophobic carboxylic acids - drugs such as naproxen, ibuprofen, ursodeoxycholic acid...
