The A2B adenosine receptor (A2BAR) was proposed as a novel target for the (immuno)therapy of cancer since A2BAR blockade results in antiproliferative, antiangiogenic, antimetastatic, and immunostimulatory effects. In this study, we explored the structure-activity relationships of xanthin-8-yl-benzenesulfonamides mainly by introducing a variety of linkers and substituents attached to the sulfonamide residue. A new, convergent strategy was established, which facilitated the synthesis of the target compounds. Many of the new compounds exhibited subnanomolar affinity for the A2BAR combined with high selectivity. Functional groups were introduced, which will allow the attachment of dyes and other reporter groups. 8-(4-((4-(4-Bromophenyl)piperazin-1-yl)sulfonyl)phenyl)-1-propylxanthine (34, PSB-1901) was the most potent A2B-antagonist (Ki 0.0835 nM, KB 0.0598 nM, human A2BAR) with >10 000-fold selectivity versus all other AR subtypes. It was similarly potent and selective at the mouse A2BAR, making it a promising tool for preclinical studies. Computational studies predicted halogen bonding to contribute to the outstanding potency of 34.

Compounds are provided that act as potent antagonists of the CCR1 receptor, and which have been further confirmed in animal testing for inflammation, one of the hallmark disease states for CCR1. The compounds are generally aryl piperazine derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR1-mediated diseases, and as controls in assays for the identification of competitive CCR1 antagonists.
