Organofluorine compounds are known to be toxic to a broad variety of living beings in different habitats, and chemical fluorination has been historically exploited by mankind for the development of therapeutic drugs or agricultural pesticides. On the other hand, several studies so far have demonstrated that, under appropriate conditions, living systems (in particular bacteria) can tolerate the presence of fluorinated molecules (e.g., amino acids analogues) within their metabolism and even repurpose them as alternative building blocks for the synthesis of cellular macromolecules such as proteins. Understanding the molecular mechanism behind these phenomena would greatly advance approaches to the biotechnological synthesis of recombinant proteins and peptide drugs. However, information about the metabolic effects of long-term exposure of living cells to fluorinated amino acids remains scarce. Hereby, we report the long-term propagation of Escherichia coli (E. coli) in an artificially fluorinated habitat that yielded two strains naturally adapted to live on fluorinated amino acids. In particular, we applied selective pressure to force a tryptophan (Trp)-auxotrophic strain to use either 4- or 5-fluoroindole as essential precursors for the in situ synthesis of Trp analogues, followed by their incorporation in the cellular proteome. We found that full adaptation to both fluorinated Trp analogues requires a low number of genetic mutations but is accompanied by large rearrangements in regulatory networks, membrane integrity, and quality control of protein folding. These findings highlight the cellular mechanisms behind the adaptation to unnatural amino acids and provide the molecular foundation for bioengineering of novel microbial strains for synthetic biology and biotechnology.

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. you can also check out more blogs about 13739-02-1. SDS of cas: 13739-02-1.

A sequential acidic ionic liquid catalyzed one pot approach was conducted for preparation of 3-substituted indoles starting from in situ generated chalcones involving Claisen-Schmidt condensation of substituted aromatic aldehydes with acetophenone followed by Michael-like addition of indoles to these chalcones under solvent-free thermal reactions. For this purpose, some new and some reported Bronsted acidic ionic liquids, 2-alkyl-1, 3-disulfoimidazolium carboxylate [RDSIM][X] (where R= Me & Et and X=CH3COO-, CCl3COO-, CF3COO-), were analyzed to compare their Bronsted acidic strength and thermal stabilities. From this investigation, 2-methyl-1, 3-disulfoimidazolium trifluoroacetate [MDSIM][CF3COO] and 2ethyl-1,3-disulfoimidazolium trifluoroacetate [EDSIM][CF3COO] were determined as efficient ionic liquid catalysts for study of the two-step one pot synthesis of 3-substituted indoles.

Due to their biological activity, indoles and substituted indoles have attracted considerable attention from both synthetic and medicinal scientists. Much effort has been directed toward the development of methods for the functionalization of the indole nucleus. The protocol uses a catalytic amount of catalyzed platinum as a promoting agent, producing N-allylated indoles in considerable yields. Moreover, water, with its large heat capacity, is one of the most abundant molecules on earth. The use of water as a solvent may bring about many environmental benefits. Herein, we have demonstrated that the platinum-catalyzed selective N-allylation of 2,3-disubstituted indoles proceeds in water. This method provides a simple, convenient, and efficient way to afford a high yield of N-allylated indoles.
