small molecule drug-like inhibitors blocking both nitricoxide synthase and NFκB could offer a synergistic therapeutic approach in the prevention and treatment of inflammation and cancer. During the course of evaluating the biological potential of a commercial compound library, 2-phenylindole (1) displayed inhibitory activity against nitrite production and NFκB with IC50 values of 38.1 ± 1.8 and 25.4
The synthesis of 2-substituted indoles starting from the corresponding unprotected 2-alkynylanilines was made possible in 3% TPGS-750-M water using Pd(OAc)2 alone as the catalyst. The reaction was sensitive to the heating mode respect to the nature of the starting material as, in many cases, convectional heating was better than microwave dielectric heating. The MW (microwave) delivery mode had also

TPGS-750-M. The route relies on a newly developed ppm level Au-catalyzed 5-endo-dig cyclization of ortho-acetylenic anilines to form the required indole moiety as a key step. Several examples showcase the generality of this cyclization. Assessment of the greenness of this approach is made by comparison of the overall E Factor, which is reduced by 54% relative to the existing route to tezacaftor. DFT
