Therefore, strategies to induce apoptosis in cancer cells by mimicking the TRAIL emerge as a promising therapeutic tool. Hence, approaches are taken to develop TRAIL/DR-based cancer therapeutics. The recombinant soluble TRAIL (rhTRAIL) and death receptor agonistic antibodies were produced and tested pre-clinically and clinically. Pre-clinical and clinical trial data demonstrate that these therapeutics are safe and relatively well tolerated. But some of these therapeutics failed to exert adequate efficacy in clinical settings.

Initial screenings of their QS inhibitory activities were conducted against <em>Pseudomonas aeruginosa</em> PAO1 and <em>Chromobacterium violaceum</em> CV026. Notably, six 3-(2-isocyanobenzyl)-1<em>H</em>-indole derivatives (4, 12, 25, 28, 32, and 33) exhibited promising QS, biofilms, and pyocyanin inhibitory activities under minimum inhibitory concentrations (MICs) against <em>P. aeruginosa</em> PAO1.

Further comprehensive studies revealed that derivative 32 at 25 μg mL<small><sup>−1</sup></small> inhibited biofilm formation by 70% against <em>P. aeruginosa</em> PAO1, as confirmed by scanning electron microscopy (SEM).
