Asymmetric N-alkylations of isatins with enals were shown to be feasible via a prolinol-catalyzed iminium activation, and N-alkylated isatins were obtained in good yields and with excellent enantioselectivity. The biologically useful N-alkylated isatins also served as valuable synthetic precursors, and could be readily converted to chiral N-alkylated indole derivatives. The described method pro...

A number of N-arylmethyl substituted indole derivatives have been synthesized and their effectiveness against ADP and arachidonic acid induced platelet aggregation in human plasma was determined. The desired compounds were synthesized by reacting the appropriate aniline derivative with isatin (or substituted isatin) to form the corresponding imine structures. The so formed compound was then act...

Abstract The class of heterocyclic compounds exhibits a variety pharmacological actions, long employed as an active ingredient in drug design and production. Indole its derivatives are crucial medicinal chemistry. Due to physiological action, it has been gaining lot interest by exhibiting antibacterial, anticonvulsant, antifungal, antimalarial, antidiabetic, antidepressant, anticancer, antimicr...

The putative prenyltransferase gene ACLA_031240 belonging to the dimethylallyltryptophan synthase superfamily was identified in the genome sequence of Aspergillus clavatus and overexpressed in Escherichia coli. The soluble His-tagged protein EAW08391 was purified to near homogeneity and used for biochemical investigation with diverse aromatic substrates in the presence of different prenyl dipho...

The article includes a review of available literature sources on toxicology research and the use indole its derivatives. Indole - benzo[β]pyrrole, with molecular weight 117.18, these are colorless crystals that have weak smell naphthalene. Under various conditions chem-ical interaction, it easily forms many biologically active compounds

The materials and methods of pharmacological toxicological study indole derivatives are presented. choice experimental biological models for the experiment is justified

1,1,2-trimethyl-1H-benzo[e]indole is an important heterocyclic compound, its available in reasonable price and can easily modified to make a good intermediate for other derivatives. That quite enough reasons use as starting material new series of compounds with biomolecules such monosaccharides after simple modification. The target molecules show biological activity. So, the current work aiming...

The development of multicomponent reactions for indole synthesis is demanding and has hardly been explored. The present study describes the development of a novel multicomponent, cascade approach for indole synthesis. Various substituted indole derivatives were obtained from simple reagents, such as unfunctionalized alkenes, diazonium salts, and sodium triflinate, by using an established straig...

The ability of indole derivatives to facilitate RNA polymerase transcription of the L-arabinose operon in Escherichia coli was shown to require the catabolite activator protein (CAP) as well as the araC gene product. Adenosine 3',5'-monophosphate (cAMP) was not obligatory for araBAD transcription when the cells were grown in the presence of 1 mM indole-3-acetic acid or in the presence of indole...
