The anthranilic acid diamides represent the most recent class of nonpeptide CCK1 receptor (CCK1-R) antagonists. Herein we describe the second phase of the anthranilic acid C-terminal optimization using nonproteinogenic amino acids containing a phenyl ring in their side chain. The Homo-Phe derivative 2 (VL-0797) enhanced 12-fold the affinity for the rat CCK1-R affinity and 15-fold for the human CCK1-R relative to the reference compound 12 (VL-0395). The eutomer of 2 (6) exhibited a nanomolar range affinity toward the human CCK1-R and was at least 400-fold selective for the CCK1-R over the CCK2-R. Molecular docking in the modeled CCK1-R and its validation by site-directed mutagenesis experiments showed that the 6 binding site overlaps that occupied by the C-terminal bioactive region of the natural agonist CCK. Owing to their interesting properties, new compounds provided by this study represent a solid basis for further advances aimed at synthesis of clinically valuable CCK1-R antagonists.

A series of 2-substituted 2-aminopropane-1,3-diols was synthesized and evaluated for their lymphocyte-decreasing effect and immunosuppressive effect on rat skin allograft. A phenyl ring was introduced into the alkyl chain of the lead compound 3, which is an immunosuppressive agent structurally simplified from myriocin (1, ISP-I) via compound 2. The potency of the various compounds was dependent upon the position of the phenyl ring within the alkyl side chain. The most suitable length between the quaternary carbon atom and the phenyl ring was two carbon atoms. 2-Substituted 2-aminoethanols were successively synthesized and evaluated for their T-cell-decreasing effect and immunosuppressive effect using a popliteal lymph node gain assay in rats. The absolute configuration at the quaternary carbon affected the activity, and the (pro-S)-hydroxymethyl group of compound 6 was essential for potent immunosuppressive activity. Favorable substituents for the (pro-R)- hydroxymethyl group of 6 were hydroxyalkyl (hydroxyethyl and hydroxypropyl) or lower alkyl (methyl and ethyl) groups. 2-Amino-2-[2-(4- octylphenyl)ethyl]propane-1,3-diol hydrochloride (6, FTY720) was found to possess considerable activity and is expected to be useful as an immunosuppressive drug for organ transplantation.
