Chirality and stereoselectivity in photochromic reactions

In this review, the chirality and stereoselectivity in photochromic reactions are broadly discussed. Stereoselectivity is categorized into the two main areas of enantioselectivity and diastereoselectivity. Enantioselective photochromism was discussed according to the methods of generating chirality, that is: (1) optical resolution of chiral and racemic compounds, (2) spontaneous separation of racemic compounds during crystallization, (3) chiral template-assisted photochromic reactions to preferentially generate an enantiomer or cause chirality-based events, and (4) the generation of a non-racemic mixture of the photoisomers by irradiation of circularly polarized light to the racemic starting photoisomer. Diastereoselective photochromism was discussed for each family of photochromic reactions, namely, (1) fulgides, (2) diarylethenes, (3) spiro-compounds, (4) azobenzenes, and (5) organometallic complexes. Chirality-related reactions in overcrowded alkenes are discussed in a separate chapter. These include: (1) the discovery of the light-driven molecular motor, (2) the first generation of light-driven molecular motors with unidirectional rotation, which have two chiral carbon atoms in a molecule, (3) the second generation of light-driven molecular motors with unidirectional rotation, which have a single chiral carbon atom in a molecule. Finally, two distinctive novel photochromic systems are introduced in which the reactions proceed stereoselectively, although their enantio- or diastereoselectivity during photochromic reactions have yet to be examined.

Ag@SnO2@ZnO core-shell nanocomposites assisted solar-photocatalysis downregulates multidrug resistance in Bacillus sp.: A catalytic approach to impede antibiotic resistance

In the present study, we report the solar-photocatalytic disinfection (SPCD) of a multidrug resistant (MDR) bacterium, Bacillus sp. CBEL-1 using Ag@SnO2@ZnO core-shell nanocomposites (NCs) as catalyst. Complete disinfection was observed within 210 min with a catalyst concentration of 500 mg/L when subjected to NCs mediated PCD under solar irradiation. H2O2 was found to be the key reactive oxygen species (ROS) involved in SPCD of targeted bacteria. Increase in production of 4-HNE along with change in fatty acid profile of bacteria after SPCD induced oxidative stress indicates the compromisation of bacterial cell membrane. Irreversible change in antibiotic resistance profile of the target bacteria was notice after SPCD, without recovery even after 96 h post disinfection experiments. Traditional disinfectants and UV-250 nm were found to have marginal impact on the resistance profile of the bacteria compared to that of SPCD. Disinfection achieved using the NCs were also validated for real water samples.

Synthetic studies of carolacton: Enantioselective total synthesis of C1-C8 and C9-C19 fragments of the molecule

This paper describes synthetic studies towards carolacton, a highly potent antibiotic against dental caries and endocarditis related bacterium Streptococcus mutans. The synthesis of the 12-membered lactone with a diversely functionalized keto acid side chain was accomplished by utilizing a blend of chiral pool and aldol strategies. Carbon chain C1-C8 was derived by utilizing Paterson aldol methodology and a Corey-Fuchs reaction. The C9-C19 chain was prepared by means of iterative Evans asymmetric alkylations and an E-selective cross-metathesis reaction. Georg Thieme Verlag Stuttgart New York.

From amino acids to fused chiral pyrrolidines and piperidines via the INOC route

Intramolecular nitrile oxide olefin cycloaddition (INOC) reactions of oximes 1-3 and of 24-27 derived from 1-amino acids have been found to proceed stereoselectively, yielding tricyclic fused pyrrolidines and piperidines. Further manipulation led to chiral hydroxymethyl-substituted fused piperidines 33-35 and to 3-amino-4-(1-hydroxypropyl)-2-mercaptomethyl-N- methylpiperidine (36). The structures and stereochemistries of the fused systems, as well as those of the piperidines, have been established by NMR.

Cysteine-Aminoethylation-Assisted Chemical Ubiquitination of Recombinant Histones

Histone ubiquitination affects the structure and function of nucleosomes through tightly regulated dynamic reversible processes. The efficient preparation of ubiquitinated histones and their analogs is important for biochemical and biophysical studies on histone ubiquitination. Here, we report the CAACU (cysteine-aminoethylation assisted chemical ubiquitination) strategy for the efficient synthesis of ubiquitinated histone analogs. The key step in the CAACU strategy is the installation of an N-alkylated 2-bromoethylamine derivative into a recombinant histone through cysteine aminoethylation, followed by native chemical ligation assisted by Seitz’s auxiliary to produce mono- and diubiquitin (Ub) and small ubiquitin-like modifier (SUMO) modified histone analogs. This approach enables the rapid production of modified histones from recombinant proteins at about 1.5-6 mg/L expression. The thioether-containing isopeptide bonds in the products are chemically stable and bear only one atomic substitution in the structure, compared to their native counterparts. The ubiquitinated histone analogs prepared by CAACU can be readily reconstituted into nucleosomes and selectively recognized by relevant interacting proteins. The thioether-containing isopeptide bonds can also be recognized and hydrolyzed by deubiquitinases (DUBs). Cryo-electron microscopy (cryo-EM) of the nucleosome containing H2BKC34Ub indicated that the obtained CAACU histones were of good quality for structural studies. Collectively, this work exemplifies the utility of the CAACU strategy for the simple and efficient production of homogeneous ubiquitinated and SUMOylated histones for biochemical and biophysical studies.
