“…[ 1 ] Among them, imidazolo‐indole framework has received growing attentions in recent years because of its fused heterocyclic skeleton involved in a large number of natural products and as drug candidate. [ 2 ] Several of their synthetic analogues have many biological properties, that is, antiinflamatory, [ 3 ] antimicrobial, [ 4 ] anticancer, [ 5 ] antitubercular, [ 6 ] antidengue, [ 7 ] anti‐analgesic, [ 8 ] anthelmintic, [ 9 ] antimycotic, [ 10 ] antitumor, [ 11 ] and antibacterial activities. [ 12 ] Also, the imidazole nucleus has displayed an important role in some advanced technology fields such as biological imaging, [ 13 ] glucagon receptors, [ 14 ] fluorescence labeling agents, [ 15 ] modulators of P‐glycoprotein (P‐gp)‐mediated multidrug resistance (MDR), [ 16 ] and chromophores for nonlinear optic systems (NLOS).…”
