We report on the identification of a novel small mol. inhibitor of anthrax lethal factor using a high-throughput screening approach. Guided by mol. docking studies, we carried out structure-activity relationship (SAR) studies and evaluated activity and selectivity of most promising compounds in in vitro enzyme inhibition assays and cellular assays. Selected compounds were further analyzed for their in vitro ADME properties, which allowed us to select two compounds for further preliminary in vivo efficacy studies. The data provided represents the basis for further pharmacol. and medicinal chem. optimizations that could result in novel anti-anthrax therapies.

Yuan, Tianqi published the artcileSynthesis of camphor sulfonic acid derivatives modified Mg/Al-LDH for efficient separation of propranolol enantiomers, HPLC of Formula: 21286-54-4, the publication is Applied Clay Science (2022), 106521, database is CAplus.

Designing chiral adsorption separation material with high enantioselectivity and stability is a promising route to realize the enantioselective recognition and separation of racemic mols. Here, for the first time, camphor sulfonic acid derivatives (CSA) were synthesized as a chiral resolving agent, and it was modified on Mg/Al layered double hydroxide (Mg/Al-LDH) through electrostatic self-assembly to construct functionalized chiral adsorption separation material (CSA@LDH), which could be served as an adsorbent for enantioselective recognition and separation of propranolol enantiomers (R,S-PRO). The CSA@LDH maintained the advantage of limited chiral space in layered structures to achieve the selective enrichment of R-PRO, and the e.e.% value of single separation could reach 19.5%. Meanwhile, d. functional theory (DFT) calculations supported that chiral recognition and separation were ascribed to the discrepancy in affinities stemming from the difference of π-π interaction force and hydrogen bonding capacity of CSA with R,S-PRO. Hence, considering the superior ability of hydrogen bond coordination and stereocontrol of camphor sulfonic acid derivatives, it is expected to be more widely used as a chiral resolving agent for other enantiomeric recognition and separation

A novel copper-catalyzed arylation of benzylic C-H bonds with nucleophilic arylboronic acids has been developed that provides an efficient way to synthesize various 1,1-diarylalkanes with a broad substrate scope and excellent functional group compatibility. The reactions occur at room temperature using alkylarenes as the limiting reagents, which allows access to the arylation of the more valuable and complex bioactive compounds

Ashkenazi, Nissan published the artcileNucleophilic Displacements in Alkylphosphonates: P-O Versus P-C Bond Cleavage. A Combined DFT and Experimental Study, Quality Control of 866-23-9, the publication is Phosphorus, Sulfur and Silicon and the Related Elements (2013), 188(1-3), 106-110, database is CAplus.

Potential energy surfaces for the nucleophilic displacements at P in di-Me Me, chloromethyl, dichloromethyl, and trichloromethyl phosphonates were computed by DFT methods. Sequential introduction of Cl substituents at the Me group in Me phosphonates increases the stability of transition states and intermediates, which facilitates P-C bond cleavage. While nonsubstituted di-Me methylphosphonate may undergo exclusive P-O bond cleavage, the trichlorinated analog reacts exclusively via P-C bond dissociation to form dichlorocarbene, which was trapped by various olefins to form the corresponding gem-dichlorocyclopropanes.

Morant-Giner, Marc published the artcileFunctionalisation of MoS₂ 2D layers with diarylethene molecules, COA of Formula: C15H14Cl2S2, the publication is Journal of Materials Chemistry C: Materials for Optical and Electronic Devices (2021), 9(33), 10975-10984, database is CAplus.

Functionalisation of two-dimensional (2D) materials with stimuli-responsive mols. has been scarcely investigated. Here, MoS₂ layers obtained by chem. exfoliation are covalently and non-covalently functionalised using two photoswitchable diarylethene derivatives under their open- and closed-ring isomers. The choice of these light-responsive mols. is based on their excellent thermal irreversibility and fatigue resistance. The characterization of the resultant mol./2D heterostructures proves the successful anchoring of the mols. by both approaches as well as the influence that the driving interaction has on the photoswitching behavior of the diarylethene isomers after their deposition on the 2D layer.

Boyer, John-Christopher published the artcilePhotomodulation of Fluorescent Upconverting Nanoparticle Markers in Live Organisms by Using Molecular Switches, Computed Properties of 219537-97-0, the publication is Chemistry – A European Journal (2012), 18(11), 3122-3126, S3122/1-S3122/17, database is CAplus and MEDLINE.

It is successfully demonstrated that the ability to modulate the luminescence from upconverting nanoparticles in vitro and in vivo by taking advantage of the well-understood photochem. of DTE mol. switches decorated onto nanoparticle surfaces by the use of CuACC chem. By reversibly converting the photoswitch back and forth between the two isomers by using UV and visible light, we are able to toggle the system between on (bright fluorescence) and off (quenched fluorescence) states. This process can be cycled multiple times before any degradation of the nanoparticles or the photo-switch renders the system impractical. The system has an advantage over ‘caged’ fluorophores as the luminescence of our designed nanoparticles can be repeatedly cycled through on and off states. Systems such as the one described not only have the capacity to reversibly control the intensity of the probe emission, through selective absorption, they can also alter the color of the emitted light from multicolored probes; this further enhances the imaging capabilities.

Chad published the artcileFrom slow to fast – the user controls the rate of the release of molecules from masked forms using a photoswitch and different types of light, Application In Synthesis of 219537-97-0, the publication is Chemical Communications (Cambridge, United Kingdom) (2015), 51(32), 7039-7042, database is CAplus and MEDLINE.

Exposure to UV light generates a ring-closed isomer of a diarylethene, which undergoes very slow bond breaking and release even after the light is turned off. The rate of release is increased by exposing the isomer to UV and/or visible light.

Series of alcs., amides, ureas, and sulfoxides with increasingly longer hydrocarbon chains lower progressively the thermal denaturation temperature of proteins. Several classes of compounds were investigated for effects on the stability of phospholipid vesicles. Many compounds that are known to perturb protein function also destabilize phospholipid bilayers as reflected by solute-induced loss of vesicle contents.
