The selective cleavage of BOC-peptide-OBut was investigated by the use of 85% formic acid, and it was found that BOC-peptide-OBut gave H-peptide-OBut in good yield by this procedure. This method was also applied to investigation of the selectivity of di-t-butyl esters of dibasic amino acids and N-deprotection of peptides containing these amino acids.

Methods for treating cancer are disclosed which comprise administering to a subject T cells which have been pretreated ex vivo or in vitro with fenofibric acid (FFA), an FFA prodrug, or a derivative thereof that has PPAR-α agonist activity. These compounds promote the use of fatty acid catabolism rather than glucose for energy and promote enhanced recovery of, and biomass production by, the pre-treated T cells. Still other methods comprise co-administering to a subject having a cancer characterized by a solid tumor an immunotherapeutic composition targeting an antigen or ligand on the tumor cell and the pretreated T cells. The method may also employ co-administration of a checkpoint inhibitor. Novel compositions comprise the pre-treated T cells. Novel FFA prodrugs are provided.
