    • PURPOSE: (S)-Isomer type indoline sulfonyl urea derivatives, a preparation method thereof and a pharmaceutical composition comprising the same are provided. The derivatives have improved anticancer activity and improved hydrophobic properties so as to be easily absorbed into the human body. CONSTITUTION: The (S)-4-phenyl-1-(N-(4-amino-benzoyl)-indoline-5-sulfonyl)- 4,5-dihydro-2-imidazolone derivatives are represented by the formula (1), wherein R is hydrogen, or an amino acid residue which is linked through an amide bond, and selected from glycine, alanine, valine, leucine, methionine, proline and phenylalanine. The method for preparing a compound of the formula (1a) comprises the steps of: combining a compound of the formula (7) with a compound of the formula (8) to prepare (S)-4-phenyl-1-(indoline-5-sulfonyl)-4,5-dihydro-2-imidazolone of the formula (3); reacting the compound of the formula (3) with 4-nitrobenzoylchloride of the formula (4); and reducing a nitro group of the resulting product. The method for preparing a compound of the formula (1b) comprises the steps of: condensing the compound of the formula (1a) with am amino acid of which amino group is protected with t-butoxycarbonyl; and deprotecting the amino group, wherein R' is an amino acid residue which is linked through an amide bond, and selected from glycine, alanine, valine, leucine, methionine, proline and phenylalanine.
