RESUMO
HIV-1 integrase multimerization inhibitors have recently been established as an effective class of antiretroviral agents due to their potent ability to inhibit viral replication. Specifically, quinoline-based inhibitors have been shown to effectively impair HIV-1 replication, highlighting the importance of these heterocyclic scaffolds. Pursuant of our endeavors to further develop a library of quinoline-based candidates, we have implemented a structure-activity relationship study of trisubstituted 4-arylquinoline scaffolds that examined the integrase multimerization properties of substitution patterns at the 4-position of the quinoline. Compounds consisting of substituted phenyl rings, heteroaromatics, or polycyclic moieties were examined utilizing an integrase aberrant multimerization in vitro assay. para-Chloro-4-phenylquinoline 11b and 2,3-benzo[b][1,4]dioxine 15f showed noteworthy EC50 values of 0.10 and 0.08 µM, respectively.
