N-Salicylaldehyde hydrazone modified 11-azaartemisinins and their deoxy analogues were designed and synthesized. By using various techniques including UV-vis, fluorescence, NMR as well as molecular modeling, the conformations of (3R,5aS,6R,8aS,9R,12S,12aR)-11-(((E)-2-hydroxy-5-(4-hydroxy-3-((E)-(((3R,5aS,6R,8aS,9R,12R,12aR)-3,6,9-trimethyl-10- oxodecahydro-3,12-epoxy[1,2]dioxepino[4,3-i]isoquinolin-11(12H)-yl)imino)methyl)benzyl)benzylidene)amino)-3,6,9-trimethyldecahydro-3,12-epoxy[1,2]dioxepino[4,3-i]isoquinolin-10(3H)-one (3) was analyzed, the binding behavior between 3 and hemin was measured, and the solubility-enhancing property of 3 by calix[4]carbazole was evaluated. The results show that the intramolecular hydrogen binding between the N atom of Schiff base in N-salicylaldehyde hydrazone bond and the OH favors the formation of tweezer-like conformation of 3, which enables it to interact with hemin in 1∶1 ratio. Moreover, the poor solubility of 3 in water could be enhanced due to its interaction with calix[4]carbazole, which pave the way for the further evaluation of the bioactivities of 3 in the future.
