An indole based "ratiometric" and "turn-off" tris(N-methylindolyl)methane based chemosensor depicting a contrasting fluorescent behavior towards Hg(2+) and Cu(2+) ions, exhibited NOR and YES logic functions, and also imaged intracellular Hg(2+) in cervix cancer (HeLa) cells.
N,N -Persubstituted 3-aminothioacrylamides of the general structure 3 are well-known as versatile synthons in organic chemistry [1]. They are easily available by several different routes [2], e.g., from simple N-disubstituted acetamides 1 via corresponding 1-chlorovinamidinium salts 2 [3], and are highly reactive towards a lot of preferably electrophilic reagents which are able to transform the...
A new route to 3-(4-arylmethylamino)butyl-5-arylidene-2-thioxo-1,3-thiazolidine-4-one 9 was developed in six steps from commercial 1,4-diaminobutane 1 as starting material. The key step of this multi-step synthesis involved a solution phase "one-pot two-steps" approach assisted by microwave dielectric from N-(arylmethyl)butane-1,4-diamine hydrochloride 6a-f (as source of the first point diversi...
In an attempt to identify novel therapeutics and mechanisms to differentially kill tumor cells using phenotypic screening, we identified N-benzyl indole carbinols (N-BICs), synthetic analogs of the natural product indole-3-carbinol (I3C). To understand the mode of action for the molecules we employed Cancer Cell Line Encyclopedia viability profiling and correlative informatics analysis to ident...
We present a comprehensive electronic structure analysis of two BN isosteres of indole using a combined UV-photoelectron spectroscopy (UV-PES)/computational chemistry approach. Gas-phase He I photoelectron spectra of external BN indole I and fused BN indole II have been recorded, assessed by density functional theory calculations, and compared with natural indole. The first ionization energies ...
The synthetic procedures to obtain indole derivatives with different acidic functions at position 2 of the indole are reported. The synthesised and tested derivatives comprise 5-tetrazolyl, 1,3,4-oxadiazol-5-yl-2-one, and indole-2-carboxylic acid amides with 5-aminotetrazole, methanesulphonamide and trifluoromethanesulphonamide moieties. The binding affinity was evaluated using [3H]MDL 105,519 ...
A new indole alkaloid, 12-hydroxy-N-acetyl-21(N)-dehydroplumeran-18-oic acid (13), and 11 known indole alkaloids: 3,4,5,6-tetradehydro-β-yohimbine (3), 19(E)-hunteracine (4), β-yohimbine (5), yohimbine (6), 19,20-dehydro-17-α-yohimbine (7), uleine (10), 20-epi-dasycarpidone (11), olivacine (8), 20-epi-N-nor-dasycarpidone (14), N-demethyluleine (15) and 20(E)-nor-subincanadine E (12) and a boone...
A series indole-based ligand precursors, PzRIndH (R = H, PzHIndH; R = Me, PzMeIndH; R = t-Bu, PztBuIndH; and R = Ph, PzPhIndH), have been synthesized via copper-catalyzed N-arylation (for PzHIndH) or the Bartoli indole synthesis (for PzMeIndH, PztBuIndH and PzPhIndH) reactions with moderate to high yield. Reactions of these ligand precursors with 0.7 equivalent of MgBu2 in THF (for 1) or hexane...
