Treatment of indolylmethyl Meldrum’s acids with catalytic scandium triflate and a variety of nucleophiles results in the nucleophilic displacement of the Meldrum’s acid moiety via a gramine-type fragmentation. The reaction is useful for the generation of heterocyclic compounds of significant molecular complexity.
A series of 3,3′-diindolylmethanes were prepared in high yields from indoles and aldehydes under subcritical water conditions without the addition of catalysts. 3-Alkenylindoles were also obtained ...
Hybrid bisindole-thiosemicarbazides analogs (1-18) were synthesized and screened for β-glucuronidase activity. All compounds showed varied degree of β-glucuronidase inhibitory potential when compared with standard d-saccharic acid 1,4-lactone (IC50=48.4±1.25μM). Compounds 4, 7, 9, 6, 5, 12, 17 and 18 showed exceptional β-glucuronidase inhibition with IC50 values ranging from 0.1 to 5.7μM. Compounds

Disclosed herein are compounds capable of inducing apoptosis through promoting Nur77 interaction with Bcl-2 and through modulating mitochondrial activities. Also disclosed herein are compositions and methods using these compounds and compositions. Nur77 is a key regulator of Bcl-2 activities and is capable of converting Bcl-2 from an anti-apoptotic protein to a pro-apoptotic protein. Small molecules that directly modulate the Nur77/Bcl-2 apoptotic pathways are promising for treating diseases with abnormal levels of Bcl-2, Nur77, or combinations thereof, including cancers.
A convenient and practical method for the synthesis of unsymmetrical triarylmethanes was demonstrated through a one-pot three-component double Friedel–Crafts reaction of various aliphatic, aromatic, or heteroaromatic aldehydes with N,N-dialkylanilines and indoles by using a Brønstedacidicionicliquid as the catalyst. This method was successfully applied under metal- and solvent-free conditions at
