- Rationally designed 4-phenoxy substituted prolinamide phenols organocatalyst for the direct aldol reaction in water
-
A rationally designed 4-phenoxy substituted prolinamide phenols as an efficient hydrophobic organocatalyst for direct asymmetric aldol reaction in water has been developed. High yield (up to 99%), diastereoselectivity (up to 99:1), and enantioselectivity (up to 97%) were obtained under optimal condition. The influence of substituent groups on the reactivity of catalysts was studied in detail. Crown Copyright

- Synthesis, biological evaluation, and pharmacokinetic study of prolyl-1-piperazinylacetic acid and prolyl-4-piperidinylacetic acid derivatives as VLA-4 antagonists
-
A series of prolyl-1-piperazinylacetic acid and prolyl-4-piperidinylacetic acid derivatives were synthesized and evaluated for their activity as VLA-4 antagonists. Of 22 compounds synthesized, 19 compounds showed potent activity with low nanomolar IC50 values. In addition, the representative compounds 11o and 11p with a hydroxy group in the pyrrolidine ring showed moderate plasma clearance in rats (11o, 30 ml/min/kg and 11p, 21 ml/min/kg) and in dogs (11o, 12 ml/min/kg and 11p, 9 ml/min/kg).

- VLA-4 INHIBITORS
-
The present invention relates to a compound represented by the following formula (I): (wherein, W represents WA-A1 -WB - (in which, WA is substituted or unsubstituted aryl, etc., A1 is -NR1-, single bond, -C(O)-, etc., and WB is substituted or unsubstituted arylene, etc.), R is single bond, -NH-, -OCH2-, alkenylene, etc., X is -C(O) -CH2-, etc., and M is, for example, the following formula: (in which, R11, R12 and R13 each independently represents hydrogen, hydroxyl, amino, halogen, etc., R14 is hydrogen or lower alkyl, Y represents -CH2-O-, etc., Z is substituted or unsubstituted arylene, etc., A2 is single bond, etc, and R10 is hydroxyl or lower alkoxy)), or salt thereof; and a medicament containing the same. This compound or salt thereof selectively inhibits binding of cell adhesion molecules to VAL-4 and exhibits high bioavailability so that it is useful as a preventive and/or remedy for inflammatory diseases, autoimmune diseases, metastasis, bronchial asthma, rhinostenosis, diabetes, and the like.
