According to the generally held view, the biosynthesis of melanins, the major determinants of skin colour differences in man, involves ultimately the oxidative polymerisation of 5,6-dihydroxyindole (1) promoted by the enzyme tyrosinase.We have now found that such a process is brought about more efficiently by the peroxidase/H2O2 system at physiological pHs, under which conditions the oxidation reaction leads in the early stages to a distinct pattern of oligomer products.These were isolated after acetylation and identified as the tetraacetoxybiindolyls 2 and 3 and the related trimers 4 and 5.The observed mode of polymerisation of 1 seemingly involves the attack of the nucleophilic 2-position of the indole to the electron deficient C-4 and C-7 sites of 5,6-indolequinone arising from further oxidation or disproportionation of peroxidase generated phenoxyl radicals.

A mild trifluoromethylation reaction of N,N-disubstituted hydroxylamines that is tolerant towards a variety of functional groups, including nitriles, alcohols, ketones, esters, amides, imides, and nitrogen heterocycles, is reported. The key feature of this reaction is the activation of the CF 3 reagent with either trimethylsilyl triflate or LiClO4 and partial or full deprotonation of the substrate with tetramethylguanidine or lithium diisopropylamide. Products were obtained in up to 80 % yield. Preliminary mechanistic studies suggested that the reaction follows a radical pathway in which the deprotonated hydroxylamine and a Lewis or Bronsted acid activated CF3 reagent engages in a single-electron-transfer step to generate a pair of radicals that recombine to afford the desired product. The trifluoromethylation procedure was successfully used in the modification of secondary nitrogen groups of pharmaceutically relevant targets (Fluoxetine and Mefloquine), which afforded new derivatives containing a novel N-trifluoromethoxy moiety.

Melanin play a major role in human skin protection and their biosynthesis is vital. Due to their color, they contribute to the skin pigmentation. Tyrosinase is a key enzyme involved in the first stage of melanin biosynthesis, it catalyzes the transformation of tyrosine into l-dopaquinone. The aim of the present study was to study molecules able to inhibit tyrosinase to be used in treating depigmentation-related disorders. In this study, we targeted arylthiosemicarbazone analogs with the aim to contribute to the identification of the optimal aryl ring to be linked to the thiosemicarbazone moiety. The biological activity was evaluated on commercial mushroom tyrosinase which was purified prior use. The results demonstrated that several of our compounds (1a-h, 1j, 1r and 5) had more potent inhibitory activities than kojic acid which was used as the reference inhibitor.

A Curtius-like rearrangement of hydroxamates to isocyanates was discovered. This reaction was initiated from an iron(II)-nitrenoid complex, which was generated by the iron(II)-catalyzed cleavage of N-O bonds of functionalized hydroxamates. To demonstrate the efficiency of this new Curtius-like rearrangement in synthetic chemistry, a biomimetic strategy for the one-pot preparation of bisindolylmethanes was developed.

The conversion of widely available carboxylic acids into versatile boronic esters would be highly enabling for synthesis. We found that this transformation can be effected by illuminating the N-hydroxyphthalimide ester derivative of the carboxylic acid under visible light at room temperature in the presence of the diboron reagent bis(catecholato)diboron. A simple workup allows isolation of the pinacol boronic ester. Experimental evidence suggests that boryl radical intermediates are involved in the process. The methodology is illustrated by the transformation of primary, secondary, and tertiary alkyl carboxylic acids as well as a diverse range of natural-product carboxylic acids, thereby demonstrating its broad utility and functional group tolerance.

A series of diindolylmethanes (5a-t) were designed, synthesized, and examined for their cytotoxicity against four human cancer cell lines like prostate (DU-145), lung (A549), breast (MCF-7) and cervical cancer (HeLa). These results revealed that among all the hybrids, two (5k and 5r) were identified and exhibited significant cytotoxic effect against A549 cancer cells with IC50 values of 1.65 ± 0.3 and 1.80 ± 0.8 muM respectively. To investigate the reasons for the cytotoxic activity, the conventional biological assays were carried out with 5k and 5r on the A549 cancer cells. Both hybrids led to the arrest of A549 cell lines at the G2/M phase of the cell cycle and strongly induced apoptosis. Further the apoptotic effects of 5k and 5r were confirmed by ROS, annexin-V FITC, and mitochondrial membrane potential. Moreover, structure?activity relationships were elucidated with various substitutions on these hybrids.
