3,3?-Diindolylmethanes (DIMs) are an important class of indole alkaloids that exhibit anti-inflammatory and anti-cancer effects. Herein, we report on a new, mild and efficient copper(II)-promoted decarboxylative coupling reaction of 2-(1H-indol-3-yl)acetic acid derivatives (1 a?h) with a variety of (substituted) indoles (2 a?t) yielding (un)symmetrically substituted DIMs (3 a?z, 3 aa?ai). Reaction of 2-(1H-indol-3-yl)acetic acid (1 a) with 7-azaindole led to the 3,3?-connected DIM analog 5 d, while 4-, 5-, and 6-azaindoles and benzimidazole reacted at the N1-nitrogen atom. Reaction of 1 a with 1H-indazoles led to a mixture of 1- and 2-substituted indazole derivatives. The new method allows large-scale synthesis of biologically active DIMs. (Figure presented.).

Michael addition of indoles to beta-nitrostyrenes is reported using HY zeolite as catalyst under mild reaction conditions. This methodology allows the synthesis of various indole derivatives in good to high yields at 50 C under solvent-free conditions. The short reaction time and achieving high yield of the desired products are the main advantages of the present work. The catalyst can be easily recovered and reused for six successive runs without considerable changes in yields. This Michael addition catalyzed by HY zeolite is operationally simple and can be considered as a greener protocol as it avoids the use of corrosive acids and toxic reagents.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 387-43-9, you can also check out more blogs about387-43-9

A substantial fraction of mutations that arise in the cell comes from oxidative damage to DNA bases. Oxidation of purine bases at the 8-position, yielding 8-oxo-G and 8-oxo-A, results in conformational changes (from anti to syn) that cause miscoding during DNA replication. Here we describe the synthesis and biophysical and biochemical properties of low-polarity shape mimics of 8-oxopurines, and we report that these new analogues exhibit remarkable mimicry of the mutagenic properties of the natural damaged bases. A 2-chloro-4- fluoroindole nucleoside (1) was designed as an isosteric analogue of 8-oxo-dG, and a 2-chloro-4-methylbenzimidazole nucleoside (2) as a mimic of 8-oxo-dA. The nucleosides were prepared by reaction of the parent heterocycles with Hoffer’s chlorodeoxyribose derivative. Structural studies of the free nucleosides 1 and 2 revealed that both bases are oriented syn, thus mimicking the conformation of the oxopurine nucleosides. Suitably protected phosphoramidite derivatives were prepared for incorporation into synthetic DNAs, to be used as probes of DNA damage responses, and 5?-triphosphate derivatives (3 and 4) were synthesized as analogues of damaged nucleotides in the cellular nucleotide pool. Base pairing studies in 12-mer duplexes showed that 1 and 2 have low affinity for polar pairing partners, consistent with previous nonpolar DNA base analogues. However, both compounds pair with small but significant selectivity for purine partners, consistent with the idea that the syn purine geometry leads to pyrimidine-like shapes. Steady-state kinetics studies of 1 and 2 were carried out with the Klenow fragment of Escherichia coli DNA Pol I (exo -) in single-nucleotide insertions. In the DNA template, the analogues successfully mimicked the mutagenic behavior of oxopurines, with 1 being paired selectively with adenine and 2 pairing selectively with guanine. The compounds showed similar mutagenic behavior as nucleoside triphosphate analogues, being preferentially inserted opposite mutagenic purine partners. The results suggest that much of the mutagenicity of oxopurines arises from their shapes in the syn conformation rather than from electrostatic and hydrogen-bonding effects. The new analogues are expected to be generally useful as mechanistic probes of cellular responses to DNA damage.

We report that l-threonine may substitute for l-serine in the beta-substitution reaction of an engineered subunit of tryptophan synthase from Pyrococcus furiosus, yielding (2S,3S)-beta-methyltryptophan (beta-MeTrp) in a single step. The trace activity of the wild-type beta-subunit on this substrate was enhanced more than 1000-fold by directed evolution. Structural and spectroscopic data indicate that this increase is correlated with stabilization of the electrophilic aminoacrylate intermediate. The engineered biocatalyst also reacts with a variety of indole analogues and thiophenol for diastereoselective C-C, C-N, and C-S bond-forming reactions. This new activity circumvents the 3-enzyme pathway that produces beta-MeTrp in nature and offers a simple and expandable route to preparing derivatives of this valuable building block.

Chemically modified bases are frequently used to stabilize nucleic acids, to study the driving forces for nucleic acid structure formation, and to tune DNA and RNA hybridization conditions. Nucleoside analogues are chemical means to investigate hydrogen bonds, base stacking, and solvation as the three predominant forces that are responsible for the stability of nucleic acids. To obtain deeper insight into the contributions of these interactions to RNA stability, we decided to synthesize some novel nucleic acid analogues where the nucleobases are replaced by fluoroindoles. Fluorinated indoles can be compared with fluorinated benzimidazoles to determine the role of nitrogen in five-membered ring systems. The synthesis of fluoroindole ribonucleosides as well as the X-ray crystal structures of all synthesized fluoroindole ribonucleosides are reported here. These compounds could also be building blocks for a variety of biologically active RNA analogues.
