A designed Brønsted acid enables Friedel–Crafts alkylation of indoles in water, whose hydrophobic aggregations of fluorocarbon chains, along with phenyl ring, protected acid sites from bulk water and enriched the substrates. The amphiphilic structure has been proven crucial for the high catalytic efficiency.

Imidazolium salts are shown to catalyze the rapid room temperature reaction of indoles or naphthol with aldehydes to provide bis(indolyl)methanes or bis(naphthol)methane in excellent yields and the reaction proceeds optimally in dichloromethane with no base additives. The reaction exhibits a broad substrate tolerance and occurs through nucleophilic activation of the indoles and naphthols through a

products vibrindole A (3n), arsindoline A (3i), arundine (3o) and tris(1H-indol-3-yl)methane (3j). Additionally, the synthesis of streptindole was carried out via intermediate 3g. This methodology is well suited for the synthesis of bis(indolyl)methanes: it offers good yields of products, low sensitivity to moisture and oxygen, high tolerance to different functional groups on the aldehydes such as alkynes

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.

ingestion of cruciferous vegetables, was recently described to act as a partial agonist of the anti-inflammatory cannabinoid (CB) receptor subtype CB2. In the present study, we synthesized and evaluated a series of DIM derivatives and determined their affinities for human CB receptor subtypes in radioligand binding studies. Potent compounds were additionally evaluated in functional cAMP accumulation and β-arrestin
