Costimulatory interactions are required for T cell activation and development of an effective immune response; hence, they are valuable therapeutic targets for immunomodulation. However, they, as all other protein-protein interactions, are difficult to target by small molecules. Here, we report the identification of novel small-molecule inhibitors of the CD40-CD40L interaction designed starting from the chemical space of organic dyes. For the most promising compounds such as DRI-C21045, activity (IC50) in the low micromolar range has been confirmed in cell assays including inhibition of CD40L-induced activation in NF-κB sensor cells, THP-1 myeloid cells, and primary human B cells as well as in murine allogeneic skin transplant and alloantigen-induced T cell expansion in draining lymph node experiments. Specificity versus other TNF-superfamily interactions (TNF-R1-TNF-α) and lack of cytotoxicity have also been confirmed at these concentrations. These novel compounds provide proof-of-principle evidence for the possibility of small-molecule inhibition of costimulatory protein-protein interactions, establish the structural requirements needed for efficient CD40-CD40L inhibition, and serve to guide the search for such immune therapeutics.

Irradiation of arenecarbothioamides 1 with 2-methoxyfuran 2 in benzene solution gives benzo-fused arene derivatives 3 in moderate yields.
Intermolecular photoaddition reaction of arenecarbothioamides to 2- methoxy- and 2-trimethylsiloxyfurans. Facile synthesis of arene-fused aminobenzoates by novel photoinduced benzannulation

Irradiation of arenecarbothioamides with 2-methoxyfuran in benzene solution gave arene-fused aminobenzoates in moderate yields accompanied by small amounts of arylpyrroles or arylthiophenes. In the case of 2- trimethylsiloxyfuran, arenecarbothioamides gave arene-fused aminobenzoates in good yields as sole products. It was demonstrated that certain furan derivatives are potentially useful as building blocks in photoinduced benzannulation.

Iron(III)-catalyzed regioselective direct remote C-H carboxylation of naphthyl and quinoline amides was developed using CBr4 and alcohol. The reaction involves a radical pathway using a coordination activation strategy and single electron transfer process. The use of sustainable iron catalysis, selectivity, and the substrate scope are the important practical features.

Photochemistry of the nitrogen-thiocarbonyl systems. Part 24. Photoreactions of thiobenzamide with various substituted furans: regioselective β-benzoylation and transformation of furans to other aromatic compounds

, p. 2931 - 2936 (2007/10/02)
In the photoreaction of thiobenzamide 1 with the substituted furans 2 and 8, β-benzoylation was the major reaction.With other furans, 2i, j and 8g, h, both transformation of furans to pyrroles and benzannulation occured in preference to benzoylation.
