Govindarajan, Sudhanva R.;Jain, Tanmay;Choi, Jae-Won;Joy, Abraham;Isayeva, Irada;Vorvolakos, Katherine research published ã€?A hydrophilic coumarin-based polyester for ambient-temperature initiator-free 3D printing: Chemistry, rheology and interface formationã€? the research content is summarized as follows. Initiator-free, photocurable, low-toxicity, viscoelastic polymer inks are attractive materials for creating low-modulus 3D-printed elastomeric biomedical constructs. In this work, we describe the synthesis, characterization, and 3D printing/crosslinking of a hydrophilic coumarin-PEG polyester (CPP). The viscoelastic CPP melt can be extruded at room temperature and deposited into layer-by-layer patterns. Upon UV irradiation, the coumarin pendant groups undergo [2 + 2] photocyclization, creating a thermoset network without the use of monomers, photoinitiators or propagating radicals. Voxel-voxel adhesion experiments between crosslinked and uncrosslinked material were performed to examine interfacial dynamics in a native, unperturbed state, and various attempts at 3D printing were made to assess the impact of printing conditions on the ultimate printed structure. Rheol. anal. indicates a transition point where elastic behavior overtakes viscous behavior at increasing shear rate. It is hypothesized that this transition point corresponds with changes in interface formation from “sticky” to “bouncy” behavior in voxel-voxel adhesion and 3D printing processes. Tensile-mode dynamic mech. anal. (DMA) and X-Ray microtomog. (microCT) experiments reveal interfacial defect accumulation that results in deterioration of macroscopic structural and mech. properties.

Grandes Reyes, Carlos Fitzgerald;Chen, Sung-Po R.;Bobrin, Valentin A.;Jia, Zhongfan;Monteiro, Michael J. research published ã€?Temperature-Induced Formation of Uniform Polymer Nanocubes Directly in Waterã€? the research content is summarized as follows. Conventional self-assembly methods of block copolymers in cosolvents (i.e., usually water and organic solvents) has yet to produce a pure and monodisperse population of nanocubes. The requirement to assemble a nanocube is for the second block to have a high mol. weight However, such high mol. weight block copolymers usually result in the formation of kinetically trapped nanostructures even with the addition of organic cosolvents. Here, we demonstrate the rapid production of well-defined polymer nanocubes directly in water by utilizing the thermoresponsive nature of the second block (with 263 monomer units), in which the block copolymer was fully water-soluble below its lower critical solution temperature (LCST) and would produce a pure population of nanocubes when heated above this temperature Incorporating a pH-responsive monomer in the second block allowed us to control the size of the nanocubes in water with pH and the LCST of the block copolymer. We then used the temperature and pH responsiveness to create an adaptive system that changes morphol. when using a unique fuel. This fuel (H₂O₂ + MnO₂) is highly exothermic, and the solution pH increases with the consumption of H₂O₂. Initially, a nonequilibrium spherical nanostructure formed, which transformed over time into nanocubes, and by controlling the exotherm of the reaction, we controlled the time for this transformation. This block copolymer and the water-only method of self-assembly have provided some insights into designing biomimetic systems that can readily adapt to the environmental conditions.

Focal adhesion kinase (FAK) is a tyrosine kinase with prominent roles in protein scaffolding, migration, angiogenesis, and anchorage-independent cell survival and is an attractive target for the development of cancer therapeutics. However, current FAK inhibitors display dual kinase inhibition and/or significant activity on several kinases. Although multi-targeted activity is at times therapeutically advantageous, such behavior can also lead to toxicity and confound chem.-biol. studies. We report a novel series of small mols. based on a tricyclic pyrimidothiazolodiazepinone core that displays both high potency and selectivity for FAK. Structure-activity relationship (SAR) studies explored modifications to the thiazole, diazepinone, and aniline “tail,” which identified lead compound BJG-03-025. BJG-03-025 displays potent biochem. FAK inhibition (IC₅₀ = 20 nM), excellent kinome selectivity, activity in 3D-culture breast and gastric cancer models, and favorable pharmacokinetic properties in mice. BJG-03-025 is a valuable chem. probe for evaluation of FAK-dependent biol.

Gillespie, James E.;Morrill, Charlotte;Phipps, Robert J. research published �Regioselective Radical Arene Amination for the Concise Synthesis of ortho-Phenylenediamines� the research content is summarized as follows. The formation of arene C-N bonds directly from C-H bonds is of great importance and there has been rapid recent development of methods for achieving this through radical mechanisms, often involving reactive N-centered radicals. A major challenge associated with these advances is that of regiocontrol, with mixtures of regioisomeric products obtained in most protocols, limiting broader utility. We have designed a system that utilizes attractive noncovalent interactions between an anionic substrate and an incoming radical cation in order to guide the latter to the arene ortho position. The anionic substrate takes the form of a sulfamate-protected aniline and telescoped cleavage of the sulfamate group after amination leads directly to ortho-phenylenediamines, key building blocks for a range of medicinally relevant diazoles. Our method can deliver both free amines and monoalkyl amines allowing access to unsym., selectively monoalkylated benzimidazoles and benzotriazoles. As well as providing concise access to valuable ortho-phenylenediamines, this work demonstrates the potential for utilizing noncovalent interactions to control positional selectivity in radical reactions.

Gockel, Samuel N.;Lee, SangHyun;Gay, Brittany L.;Hull, Kami L. research published �Oxidative Three-Component Carboamination of Vinylarenes with Alkylboronic Acids� the research content is summarized as follows. The three-component carboamination of alkenes is of significant interest due to the ease by which functionalized amines can be produced from readily available chem. building blocks. Previously, a variety of carbon-centered radical precursors have been studied as the carbon components for this reaction; however, the use of general alkyl sources has remained as an unsolved challenge. Herein we present our efforts to develop an oxidative carboamination protocol that utilizes alkylboronic acids as carbon-centered radical precursors. The presented work demonstrates 34 examples, ranging from 17 to 88% yields, with a broad scope in vinylarenes, amines, and alkylboronic acids. Preliminary mechanistic studies suggest that a single-electron oxidation of the alkylboronic acid generates a carbon-centered radical intermediate that adds across the olefin followed by C-N bond formation via Cu-mediated inner-sphere or carbocation-mediated pathways.
