UCB35625 is a potential inhibitor of chemokine/eosinophil interactions. UCB35625 is a trans-isomer of a compound J113863, which was originally identified by scientists at Banyu Pharmaceutical Company as a candidate small molecule chemokine receptor antagonist. UCB35625 initially identified as CCR1 and CCR3 antagonists also bind to CCR2 and CCR5 and act as full agonist, partial agonist or antagonist according to the nature of the receptor and the signaling pathway investigated. UCB35625 shows promise as a lead compound for the design of future therapeutics, which may be of use in the treatment of allergic inflammatory diseases such as asthma and also the blockade of viral entry by HIV strains that utilize CCR3.
