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.

Flexible aliphatic poly(isocyanurate-oxazolidone) resins based on poly(ethylene glycol) diglycidyl ether and 4,4?-methylene dicyclohexyl diisocyanate

New flexible aliphatic oxazolidone-isocyanurate networks (AISOX) are obtained by reacting a low molecular weight diisocyanate (4,4?-methylene dicyclohexyl diisocyanate, H12MDI) and a macro-diepoxyde (poly(ethylene glycol) diglycidyl ether, Mn = 526, PEGDGE) in different molar ratio. The curing reaction, carried out from 25 C to 200 C, is studied by using DSC and FTIR. The effect of the molar ratio of the two monomers on thermal and mechanical properties of AISOX resins is investigated by DSC, thermogravimetric analysis, stress-strain measurements and optical microscopy. Independently from the feed composition, it is observed that the reaction steps are: (i) partial hydrolysis of isocyanate caused by water traces, (ii) incomplete trimerization of isocyanate to give isocyanurate, and (iii) formation of oxazolidone and complete conversion of isocyanate. At the highest concentration of the soft macrodiepoxyde (PEGDGE), the AISOX resin is in the rubbery state at room temperature and shows an elastomeric behavior.

Studies towards a novel synthesis of tubulysins: Highly asymmetric aza-Michael reactions of 2-enoylthiazoles with metalated chiral oxazolidinones

Herein we report the highly asymmetric aza-Michael reactions of alpha,beta-enones (2-enoylthiazoles) with metalated chiral oxazolidinones under different reaction conditions and for different substituents at the beta-position of the Michael acceptor. The reaction proceeds with complete diastereoselectivity to give exclusively one of the two diastereomers. The significance of the reaction is that no catalyst has been used; the steric requirements of the chiral Michael nucleophile drive the stereospecificity of the reaction and the reaction time is much less compared to the reported procedures. This methodology might be useful for an improved total synthesis of the highly cytotoxic peptides known as the tubulysins. Georg Thieme Verlag Stuttgart.
