  Identification of pyrazolopyrimidine arylsulfonamides as CC-chemokine receptor 4 (CCR4) antagonists

  摘要：

  A novel 4-aminoindazole sulfonamide hit (13) was identified as a human CCR4 antagonists from testing a focussed library of compounds in the primary GTPcS assay. Replacing the indazole core with a pyrazolopyrimidine, and introduction of a methoxy group adjacent to the sulfonamide substituent, resulted in the identification of pyrazolopyrimidine 37a, which exhibited good binding affinity in the GTPcS assay (pIC(50) = 7.2), low lipophilicity (c logP = 2.2, chromlog D-7.4 = 2.4), high LE (0.41), high solubility (CLND solubility >= 581 mu M), and an excellent PK profile in both the rat (F = 62%) and the dog (F = 100%). Further SAR investigation of the pyrazolopyrimidine suggested that substitution at N1 is tolerated, providing a suitable vector to modulate the properties, and increase the potency in a lead optimisation campaign.
