The inclusion of an azaspiroketal Mannich base in the membrane targeting antitubercular 6-methoxy-1-n-octyl-1H-indole scaffold resulted in analogs with improved selectivity and submicromolar activity against Mycobacterium tuberculosis H37Rv. The potency enhancing properties of the spiro-fused ring motif was affirmed by SAR and validated in a mouse model of tuberculosis. As expected for membrane inserting agents, the indolyl azaspiroketal Mannich bases perturbed phospholipid vesicles, permeabilized bacterial cells, and induced the mycobacterial cell envelope stress reporter promoter piniBAC. Surprisingly, their membrane disruptive effects did not appear to be associated with bacterial membrane depolarization. This profile was not uniquely associated with azaspiroketal Mannich bases but was characteristic of indolyl Mannich bases as a class. Whereas resistant mycobacteria could not be isolated for a less potent indolyl Mannich base, the more potent azaspiroketal analog displayed low spontaneous resistance mutation frequency of 10-8/CFU. This may indicate involvement of an additional envelope-related target in its mechanism of action.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 2380-86-1

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, Recommanded Product: 4-Fluoroindole, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 387-43-9, Name is 4-Fluoroindole, molecular formula is C8H6FN.

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.

4,7-Dipyrrolidinyl-1,10-phenanthroline (DPPhen) was identified as an efficient ligand for copper catalysed selective aromatic N-arylation in water. N-Arylation of indoles, imidazoles and purines proceeds with moderate to excellent yields and complete selectivity over aliphatic amines. Aqueous medium and the possibility for low metal and ligand loadings give the process a benign environmental profile.

Herein, we report the development of an asymmetric tandem Friedel?Crafts alkylation/Michael addition of 4-substituted indoles with trans-beta-nitrostyrene derivatives. By employing a chiral ZnII-(bis)oxazoline catalyst we could control the formation of three contiguous chiral centers in one step in 57 %?99 % yield and up to > 99 % ee. This methodology provides easy access to a range of novel C4-substituted products containing the tricyclic core of the ergoline skeleton and allows for the synthesis of tetracyclic ergoline derivatives with four chiral centers, in high enantioselectivity and as single isolated diastereomers.
