Design of environment-sensitive supramolecular assemblies for intracellular drug delivery: Polymeric micelles that are responsive to intracellular pH change

Drug smuggling: Micelles made up of block copolymers and the anticancer drug adriamycin (ADR), which is linked to the polymer by a pH-sensitive linker, have been prepared (see picture). Treatment of cancer cells with the micelles shows that the micelles are transported into the cell by endocytosis, thus bypassing the cell-membrane transporters. In the cell, the decrease in pH value triggers the release of the ADR, which retains its cytotoxic effect. The released ADR fluoresces which allows its localization within the cells to be detected.

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.SDS of cas: 13590-42-6, you can also check out more blogs about13590-42-6

Capturing Intermediates in the Reaction Catalyzed by NosN, a Class C Radical S-Adenosylmethionine Methylase Involved in the Biosynthesis of the Nosiheptide Side-Ring System

Nosiheptide is a ribosomally synthesized and post-translationally modified thiopeptide natural product that possesses antibacterial, anticancer, and immunosuppressive properties. It contains a bicyclic structure composed of a large macrocycle and a unique side-ring system containing a 3,4-dimethylindolic acid bridge connected to the side chains of Glu6 and Cys8 of the core peptide via ester and thioester linkages, respectively. In addition to the structural peptide, encoded by the nosM gene, the biosynthesis of the side-ring structure requires the actions of NosI, -J, -K, -L, and -N. NosN is annotated as a class C radical S-adenosylmethionine (SAM) methylase, but its true function is to transfer a C1 unit from SAM to C4 of 3-methyl-2-indolic acid (MIA) with concomitant formation of a bond between the carboxylate of Glu6 of the core peptide and the nascent C1 unit. However, exactly when NosN performs its function during the biosynthesis of nosiheptide is unknown. Herein, we report the syntheses and use of three peptide mimics as potential substrates designed to address the timing of NosN’s function. Our results show that NosN clearly closes the side ring before NosO forms the pyridine ring and most likely before NosD/E catalyzes formation of the dehydrated amino acids, although the possibility of a more random process (i.e., NosN acting after NosD/E) cannot be ruled out. Using a substrate mimic containing a rigid structure, we also identify and characterize two reaction-based adducts containing SAM fused to C4 of MIA. The two SAM adducts are derived from a consensus radical-containing species proposed to be the key intermediate – or a derivative of the key intermediate – in our proposed catalytic mechanism of NosN.

Polymeric micelles for pH-responsive lutein delivery

There has been growing interests in nanoparticulate delivery of the natural carotenoid, lutein for anti-cancer therapy. However, the low aqueous solubility of lutein and the poor lutein release from nanocarriers limit its bioavailability and therapeutic outcome. To address this problem, we report a pH-responsive polymer micelle for on-demand delivery of lutein. The selected micelle building polymer was methoxy poly(ethylene glycol)-co-poly(aspartic acid)-imidazole that was ionically crosslinked by biocompatible iron (III). Such imidazole-iron coordination bonding is stable in neutral conditions (e.g. pH 7.4), but it could be ruined under acidic microenvironment (e.g. endosome). A control micelle was also produced with non-responsive PEGylated poly(beta-benzyl l-aspartate) (mPEG-PBLA) copolymer. The drug-loaded responsive micelles displayed a hydrodynamic size of 168.2 nm with a lutein loading of 3.5% (w/w) and iron loading of 0.2% (w/w). The pH-responsive release was verified by in vitro release test at pH 7.4 and 5.0. The half maximal inhibitory concentration of the responsive micelles in HeLa cells was ca. 58.4 muM that was significantly lower than that of control micelles. All the results suggested that the triggered cargo release aided the cytosol accumulation of lutein without the delay of therapeutic action. The current work highlighted the stimuli-responsive nanomedicine in on-demand carotenoid delivery.

Visible-Light-Mediated Liberation and In Situ Conversion of Fluorophosgene

The first example for the photocatalytic generation of a highly electrophilic intermediate that is not based on radical reactivity is reported. The single-electron reduction of bench-stable and commercially available 4-(trifluoromethoxy)benzonitrile by an organic photosensitizer leads to its fragmentation into fluorophosgene and benzonitrile. The in situ generated fluorophosgene was used for the preparation of carbonates, carbamates, and urea derivatives in moderate to excellent yields via an intramolecular cyclization reaction. Transient spectroscopic investigations suggest the formation of a catalyst charge-transfer complex-dimer as the catalytic active species. Fluorophosgene as a highly reactive intermediate, was indirectly detected via its next downstream carbonyl fluoride intermediate by NMR. Furthermore, detailed NMR analyses provided a comprehensive reaction mechanism including a water dependent off-cycle equilibrium.

Dormancy in temperate fruit trees in a global warming context: A review

Dormancy is the mechanism that plants use to protect sensitive tissue from unfavourable climatic conditions. In a changing global environment, temperate fruit crop adaptation might be at risk due to changes in temperature cues. A complete picture of dormancy is shown in this review, using results from the early, pioneering work to the molecular basis, also emphasising dormancy modelling and measurement and their implication in temperate fruit production. This description is completed by the variability that climatic change might induce in plants through direct or indirect changes in dormancy. Future avenues for the correct adaptation of temperate fruit crops are proposed that span basic questions, from temperate fruit distribution to more-applied questions of dormancy, such as application of rest-breaking agents, depth-of-dormancy markers, breeding strategies, cross-pollination and host-pest interaction. In the context of global climate change, a linkage among the cited fields is intended in this review in order to raise awareness in the scientific community.

Porphyrin-functionalized amphiphilic diblock copolypeptides for photodynamic therapy

A series of amphiphilic diblock copolypeptides (ADCs), 5-(4-aminophenyl)- 10,15,20-triphenyl-porphyrin (APP) conjugated poly(L-leucine)-block-polylysine (APP-LnKm) with different molar ratios of L-leucine unit and lysine unit were designed and synthesized. The optimized composition of the polypeptide was determined to be APP-L109K186, which has high fluorescence quantum yield and could self-assemble into micelles in an aqueous medium with mean particle size <30 nm. The in vitro study indicates that APP-L109K186 shows no significant dark cytotoxicity when the concentration is below 200 mg L-1 for HepG2 and HeLa cells. In contrast, the polymer exhibits apparent phototoxicity with low IC 50 values toward HepG2 and HeLa cells, implying that the potential high photodynamic therapy efficacy of the polymer.

Integrated CO2 capture-fixation chemistry via interfacial ionic liquid catalyst in laminar gas/liquid flow

Simultaneous capture of carbon dioxide (CO2) and its utilization with subsequent work-up would significantly enhance the competitiveness of CO2-based sustainable chemistry over petroleum-based chemistry. Here we report an interfacial catalytic reaction platform for an integrated autonomous process of simultaneously capturing/fixing CO2 in gas-liquid laminar flow with subsequently providing a work-up step. The continuous-flow microreactor has built-in silicon nanowires (SiNWs) with immobilized ionic liquid catalysts on tips of cone-shaped nanowire bundles. Because of the superamphiphobic SiNWs, a stable gas-liquid interface maintains between liquid flow of organoamines in upper part and gas flow of CO2 in bottom part of channel. The intimate and direct contact of the binary reagents leads to enhanced mass transfer and facilitating reactions. The autonomous integrated platform produces and isolates 2-oxazolidinones and quinazolines-2,4(1H,3H)-diones with 81-97% yields under mild conditions. The platform would enable direct CO2 utilization to produce high-valued specialty chemicals from flue gases without pre-separation and work-up steps.

Investigation of the noncovalent binding mode of covalent proteasome inhibitors around the transition state by combined use of cyclopropylic strain-based conformational restriction and computational modeling

To develop potent covalent inhibitors, the noncovalent interactions around the transition state to form covalent bonding should be optimized because the potency of the inhibitor can be depending on the energy of the transition state. Here, we report an efficient analysis of the noncovalent binding mode of a potent covalent proteasome inhibitor 3a around the transition state by a combined use of the chemical approach, i.e., the cyclopropylic strain-based conformational restriction, and the computational docking approach. Furthermore, we calculated the binding energy of a series of salinosporamide derivatives in the predicted noncovalent complex around the transition state with the simulation model of proteasome constructed in this study, which was well correlated to their pIC50. Thus, the proposed docking methods to predict the noncovalent binding mode around the transition state of covalent inhibitors will be helpful toward the development of covalent inhibitors.
