Heck Diversification of Indole-Based Substrates under Aqueous Conditions: From Indoles to Unprotected Halo-tryptophans and Halo-tryptophans in Natural Product Derivatives

The blending of synthetic chemistry with biosynthetic processes provides a powerful approach to synthesis. Biosynthetic halogenation and synthetic cross-coupling have great potential to be used together, for small molecule generation, access to natural product analogues and as a tool for chemical biology. However, to enable enhanced generality of this approach, further synthetic tools are needed. Though considerable research has been invested in the diversification of phenylalanine and tyrosine, functionalisation of tryptophans thorough cross-coupling has been largely neglected. Tryptophan is a key residue in many biologically active natural products and peptides; in proteins it is key to fluorescence and dominates protein folding. To this end, we have explored the Heck cross-coupling of halo-indoles and halo-tryptophans in water, showing broad reaction scope. We have demonstrated the ability to use this methodology in the functionalisation of a brominated antibiotic (bromo-pacidamycin), as well as a marine sponge metabolite, barettin.

Dynamics of electronically excited states in the eumelanin building block 5,6-dihydroxyindole

We report the first excited state dynamics study of gas-phase 5,6-dihydroxyindole (5,6-DHI), a key building block of eumelanin pigments that are found throughout nature and serve as important photo-protective compounds. Time-resolved ion-yield measurements over the 241-296 nm ultraviolet photoexcitation region revealed non-adiabatic processes occurring on up to three distinct timescales. These reflect ultrafast (i.e. sub-picosecond) internal conversion within the excited state singlet manifold, and much longer-lived processes ranging from 10 ps to in excess of 1 ns. Our investigation paves the way for precisely targeted future studies of 5,6-DHI that exploit more differential measurement techniques. The work was facilitated by the use of soft laser-based thermal desorption to introduce 5,6-DHI samples into the gas phase. This approach, based on low-cost, readily available diode lasers, is straightforward, easily controllable and potentially applicable to a wide range of non-volatile molecular species.

Irreversible inhibition of DNA polymerase beta by small-molecule mimics of a DNA lesion

Abasic sites are ubiquitous DNA lesions that are mutagenic and cytotoxic but are removed by the base excision repair pathway. DNA polymerase beta carries out two of the four steps during base excision repair, including a lyase reaction that removes the abasic site from DNA following incision of its 5?-phosphate. DNA polymerase beta is overexpressed in cancer cells and is a potential anticancer target. Recently, DNA oxidized abasic sites that are produced by potent antitumor agents were shown to inactivate DNA polymerase beta. A library of small molecules whose structures were inspired by the oxidized abasic sites was synthesized and screened for the ability to irreversibly inhibit DNA polymerase beta. One candidate (3a) was examined more thoroughly, and modification of its phosphate backbone led to a molecule that irreversibly inactivates DNA polymerase beta in solution (IC50 ? 21 muM), and inhibits the enzyme’s lyase activity in cell lysates. A bisacetate analogue is converted in cell lysates to 3a. The bisacetate is more effective in cell lysates, more cytotoxic in prostate cancer cells than 3a and potentiates the cytotoxicity of methyl methanesulfonate between 2- and 5-fold. This is the first example of an irreversible inhibitor of the lyase activity of DNA polymerase beta that works synergistically with a DNA damaging agent.

Novel indole-based analogs of melatonin: Synthesis and in vitro antioxidant activity studies

The aim of this study was to synthesize and examine possible in vitro antioxidant effects of indole-based melatonin analogue compounds. As a part of our ongoing study nineteen indole hydrazide/hydrazone derivatives were synthesized, characterized and their in vitro antioxidant activity was investigated by three different assays: by evaluating their reducing effect against oxidation of a redox sensitive fluorescent probe, by examining their protective effect against H2O2-induced membrane lipid peroxidation and by determining their inhibitory effect on AAPH-induced hemolysis of human erythrocytes. The results indicated significant strong antioxidant activity for most of the compounds, when compared to melatonin. Copyright

Tandem Rh(II) and Chiral Squaramide Relay Catalysis: Enantioselective Synthesis of Dihydro-beta-carbolines via Insertion to C-H Bond and Aza-Michael Reaction

An efficient tandem rhodium(II)/squaramide relay catalysis of readily accessible indole derivatives and N-sulfonyl-1,2,3-triazoles has been developed for the enantioselective synthesis of dihydro-beta-carbolines in good yield and enantioselectivity. The developed reaction involves selective insertion of in situ generated azavinyl rhodium carbene onto the C3-H bond of indole derivatives and subsequent squaramide-catalyzed enantioselective intramolecular aza-Michael reaction. Furthermore, the potential of the strategy was demonstrated through the ready conversion to potent tetrahydro-beta-carbolines and the tetracyclic alkaloid core structure.
