The paradigm, derived from bicyclams and other cyclams, by which it is necessary to use the p-phenylene moiety as the central core in order to achieve high HIV-1 antiviral activities has been reexamined for the more flexible and less bulky structures 4, previously described by our group as potent HIV-1 inhibitors. The symmetrical compounds 7{x,x} and the non-symmetrical compounds 8{x,y} were designed, synthesized and biologically evaluated in order to explore the impact on the biological activity of the distance between the phenyl ring and the first nitrogen atom of the side chains. EC50 exactly followed the order 7{x,x} < 8{x,x} < 4{x,x} indicating that, for such flexible tetramines, the presence of two methylene units on each side of the central phenyl ring increases the biological activity contrary to AMD3100. A computational study of the interactions of 4{3,3}, 7{3,3} and 8{3,3} with CXCR4 revealed interactions in the same pocket region with similar binding modes for 4{3,3} and 7{3,3} but a different one for 8{3,3}.
