Abstract: An objective of the present invention is to provide lymphatically-transported self-emulsifying formulations for enhancing membrane permeability of poorly membrane-permeable compounds in oral administration of the compounds. It was discovered that by applying lymphatically-transported self-emulsifying formulations containing a surfactant containing oleic acid as a moiety or oily component to poorly membrane-permeable compounds containing a cyclic peptide and having features (i) and (ii) below, the membrane permeability and absorbability of the compounds can be improved: (i) log D (pH 7.4) value of the compounds is 3.2 or greater; and (ii) Caco-2 Papp (cm/sec) value of the compounds is 1.8E-6 or less.

Abstract: An object of the present invention is to provide methods of discovering drugs effective for tough targets, which have conventionally been discovered only with difficulty. The present invention relates to novel methods for cyclizing peptide compounds, and novel peptide compounds and libraries comprising the same, to achieve the above object.
