ring within pocket A of the enzyme. On this basis, chemical modifications were proposed to increase inhibition activity. Synthetic routes had to be adapted and optimized to yield the desired substituted 4- and 5-arylthiazolinethiones. Their biological evaluation shows that 5-aryl regioisomers are systematically less potent than the corresponding 4-aryl analogs. Substitution on the phenyl ring does not
The object of the present invention is to provide a compound having a treatment effect based on a chemokine inhibitory activity, which is satisfactory as a pharmaceutical product for oral administration.
The present inventors have found that the following benzylpiperidine derivative (the formula (1)) has a chemokine inhibitory activity. Further intensive studies have resulted in successful enhancement of the chemokine inhibitory activity and stability in blood of the present compound, as well as the completion of the present invention.
