... coincide with the region that binds HR1 upon 6HB formation. The strong affinity of RC-101 for HR2 prevents the inter- action of HR1 and HR2, formation of the 6HB, and subsequent fusion of the host ... regions of gp41 [12]. During 100 days of serial passaging, HIV-1 strain BaL developed three cationic mutations in the presence of sublethal concentrations of RC-101 [1...
