In light of a proposed molecular mechanism for the C-X-C chemokine receptor type 4 (CXCR4) antagonist 1 (AMD3100), a template with the general structure 2 was designed, and 15 was identified as a lead by means of an affinity binding assay against the ligand-mimicking CXCR4 antagonist 3 (TN14003). Following a structure-activity profile around 15, the design and synthesis of a series of novel small molecular CXCR4 antagonists led to the discovery of 32 (WZ811). The compound shows subnanomolar potency (EC50 = 0.3 nM) in an affinity binding assay. In addition, when subjected to in vitro functional evaluation, 32 efficiently inhibits CXCR4/stromal cell-derived factor-1 (SDF-1)-mediated modulation of cyclic adenosine monophophate (CAMP) levels (EC50 = 1.2 nM) and SDF-1 induced Matrigel invasion (EC50 = 5.2 nM). Molecular field topology analysis (MFTA), a 2D quantitative structure-activity relationship (QSAR) approach based on local molecular properties (Van der Waals radii (VdW), atomic charges, and local lipophilicity), applied to the 32 series suggests structural modifications to improve potency.

We describe here a commercially available Pt/C catalyst capable of catalyzing the methylation of anilines and aromatic imines with formic acid in the presence of a hydrosilane reductant. Both primary aniline and secondary aniline can be methylated. The advantage of this newly described method includes operational simplicity, high TON, ready availability of the catalyst, and also good functional group
series of novel tertiaryamine derivatives targeting CXCR4 were designed, synthesized, and evaluated. The central benzene ring linker and sidechains were modified and optimized to study the structure–activity relationship. Seven compounds displayed much more potent activity than the reference drug, AMD3100, in both the binding affinity assay and the blocking of Matrigel invasion functional assay. These
