Preparation and Characterization of Thermally Stable Polybenzoxazole Copolymer Films Fabricated from Their Precursors

The polyhydroxyamide copolymers (F-PHAs) were synthesized by low-temperature solution polycondensation of 2,2-bis(3-amino-4-hydroxyphenyl) hexafluoropropane (BAHHFP) and/or 3,3 ‘-dihydroxybenzidine (DHB) with terephthaloyl chloride (TPC) in N,N-dimethylacetamide (DMAc) with the aid of lithium chloride (LiCl). A series of polybenzoxazole copolymer (F-PBO) films were fabricated via an efficient solution-casting and thermal-treatment technique, using their precursors (F-PHA films) with different BAHHFP fractions (25-100 mol%). The solubility results show that F-PHAs with higher BAHHFP content (>= 75 mol%) are readily soluble in anhydrous DMAc and N-methyl-2-pyrrolidinone (NMP) without LiCl at room temperature. Differential scanning calorimetry (DSC) indicates that the thermal cyclization temperature of the F-PHA films decreases with increasing BAHHFP content. Thermogravimetric analysis (TGA) reveals that the F-PHA and F-PBO films are well prepared and completely converted. The UV-visible spectra indicate that the F-75-PBO film (BAHHFP content: 75 mol%) has reasonable transparency, with 84.9 % transmittance at 600 nm and 397-nm UV cut-off wavelength. It also has lower coefficient of thermal expansion (CTE) (48 ppm/degrees C) and water absorption (WA) values (0.14%). The BAHHFP as diamine component provides the final F-PBO film with desirable properties, e.g., flexibility, thermal stability, transparency, and WA values.

Identification of novel 2-benzoxazolinone derivatives with specific inhibitory activity against the HIV-1 nucleocapsid protein

In this report, we present a new benzoxazole derivative endowed with inhibitory activity against the HIV-1 nucleocapsid protein (NC). NC is a 55-residue basic protein with nucleic acid chaperone properties, which has emerged as a novel and potential pharmacological target against HIV-1. In the pursuit of novel NC-inhibitor chemotypes, we performed virtual screening and in vitro biological evaluation of a large library of chemical entities. We found that compounds sharing a benzoxazolinone moiety displayed putative inhibitory properties, which we further investigated by considering a series of chemical analogues. This approach provided valuable information on the structure-activity relationships of these compounds and, in the process, demonstrated that their anti-NC activity could be finely tuned by the addition of specific substituents to the initial benzoxazolinone scaffold. This study represents the starting point for the possible development of a new class of antiretroviral agents targeting the HIV-1 NC protein. (C) 2017 Elsevier Masson SAS. All rights reserved.

Discovery of novel series of 2-substituted benzo[d]oxazol-5-amine derivatives as multi-target directed ligands for the treatment of Alzheimer’s disease

Alzheimer’s disease (AD) is associated with multifactorial neuropathological conditions, which include cholinergic deficit, amyloid-beta plaques formation, loss of neuronal plasticity and neuronal death. Treating such multifactorial conditions with a single target directed approach is considered to be inadequate. Accordingly, multi-target directed ligand (MTDL) strategy has been evolved as an auspicious approach for the treatment of AD. In light of that, a library of 2-substituted benzo[d]oxazol-5-amine derivatives (29-39; 86-107) was designed using the scaffold hopping guided MTDLs strategy, synthesized and evaluated through various in-vitro and in-vivo biological studies. The optimal compound 92 exhibited potent inhibitory activities against AChE (IC50 = 0.052 +/- 0.010 mu M), BuChE (IC50 = 1.085 +/- 0.035 mu M), and significant amyloid-beta aggregation (20 mu M) inhibition. The compound possessed better blood-brain barrier permeability (Pe = 10.80 +/- 0.055 x 10(-6) cm s(-1)) in PAMPA assay and neuro protective properties (40 mu M) on SH-SY5Y neuroblastoma cell lines. Furthermore, in-vivo behavioural studies were performed on Y-maze test (scopolamine-induced amnesia model) and Morris water maze test (A beta(1-42) induced ICV rat model). The compound 92, at a dose of 10 mg/kg oral administration, demonstrated a substantial improvement of the cognitive and special memory impairment. In summary, both in-vitro and in-vivo investigations evidenced that compound 92 was a potential lead for the discovery of safe and effective disease-modifying agents for AD.

Cardo-type porous organic nanospheres: Tailoring interfacial compatibility in thermally rearranged mixed matrix membranes for improved hydrogen purification

Mixed-matrix membrane (MMM) is an effective way to overcome trade-off limitations of conventional polymeric membranes. However, the existence of defect voids at the polymer/filler interface often limits their performance improvement. Similar issues are also present in thermally rearranged polybenzoxazole (TR-PBO)-derived MMMs. To address this challenge, the selection of fillers is of great importance. Herein, a novel organic porous nanosphere (TC-cPSB), which is prepared by the polycondensation of 9,9-bis(4-aminophenyl) fluorene (BAFL) and terephthalaldehyde (TPAL) followed by thermal crosslinking, is chosen to engineer the polymer/filler interface. Benefiting from strong intermolecular interaction (pi-pi stacking and hydrogen bonding), the TC-cPSB nanosphere can well disperse in TR-PBO matrix with a defect-free interface. With an increase in TC-cPSB loading, well-designed MMMs exhibit a significant anti-trade-off’ phenomenon whereby gas permeability and selectivity increase simultaneously, following the trend predicted by the Maxwell model. Compared with TR-PBO membrane, the MMM containing 15 wt% of nanosphere shows an increase of 282% and 217.6% in H-2/CO2 selectivity and H-2 permeability, respectively, which is far beyond 2008 Robeson upper bound.

The photooxidative sensitization of bis(p-substituted diphenyl)iodonium salts in the radical polymerization of acrylates

The ability of two-component dyeing photoinitiating systems for the radical polymerization of 1,6-hexanediol diacrylate (HDDA) and 2-ethyl-2-(hydroxymethyl)-1,3-propanediol triacrylate (TMPTA) is presented. The systems under study comprised a hemicyanine dye as a sensitizer and iodonium salts that played a role of a coinitiator. The kinetic parameters of the polymerization reaction, such as the rate of polymerization (R-p) and the degree of conversion of monomer (C-%), were estimated. The thermodynamic feasibility of an electron transfer process in the systems studied was verified and calculated using the Rehm-Weller equation. It was found that a benzoxazole derivative in the presence of iodonium salts effectively initiated the polymerization of acrylate monomers. The polymerization rates of about 10(-7) s(-1) and the degree of conversion of acrylate groups from 20% to 50% were observed. The effects of photoinitiator structures on the initiating ability and spectroscopic properties of sensitizers are described in this article.

Synthesis and biological evaluation of novel N-aryl-omega-(benzoazol-2-yl)-sulfanylalkanamides as dual inhibitors of alpha-glucosidase and protein tyrosine phosphatase 1B

alpha-Glucosidase is known to catalyze the digestion of carbohydrates and release free glucose into the digestive tract. Protein tyrosine phosphatase 1B (PTP1B) is engaged in the dephosphorylation of the insulin receptor and regulation of insulin sensitivity. Therefore, dual antagonists by targeting both -glucosidase and PTP1B may be potential candidates for type 2 diabetes therapy. In this work, three series of novel N-aryl–(benzoazol-2-yl)-sulfanylalkanamides were synthesized and assayed for their -glucosidase and PTP1B inhibitory activities, respectively. Compound 3l, exhibiting the most effective -glucosidase inhibitory activity (IC50=10.96m (3l), IC50=51.32m (Acarbose), IC50=18.22m (Ursolic acid)) and potent PTP1B inhibitory activity (IC50=13.46m (3l), IC50=14.50m (Ursolic acid)), was identified as a novel dual inhibitor of -glucosidase and PTP1B. Furthermore, 3l is a highly selective PTP1B inhibitor because no inhibition was showed by 3l at 100m against PTP-MEG2, TCPTP, SHP2, or SHP1. Subsequent kinetic analysis revealed 3l inhibited -glucosidase in a reversible and mixed manner. Molecular docking study indicated that hydrogen bonds, van der Waals, charge interactions and Pi-cation interactions all contributed to affinity between 3l and -glucosidase/PTP1B.

An atomistic insight on CO2 plasticization resistance of thermally rearranged 6FDA-bisAPAF

An emerging class of thermally rearranged (TR) polymer has been of great interest for its extraordinary transport properties. More importantly, harnessing the full potential of TR polymer as gas separation membrane for CO2/CH4 separation is through its ability to resist plasticization at high pressures. Accordingly, we report here on the effect of CO2-induced plasticization on polyimide precursor (6FDA-bis-APAF: 4,4-hexafluoro isopropylidenediphthalic anhydride -2,2′-bis(3-amino-4-hydroxyphenyl) – hexafluoropropane) and on the resulting thermally rearranged polybenzoxazole (TR-PBO) polymer membranes as investigated through the radial distribution function and accessible free volume analyses. Using molecular simulation techniques, structural properties such as d-spacing, glass transition temperature, fractional free volume, etc. were estimated in agreement with wide range of experimental observations, which are published within the last decade. Results showed that, TR polymer displayed restricted % FFV increase up to 40 bar due to its limited chain mobility as indicated by the dihedral distribution, and sorption sites on its backbone with lower affinity to CO2 as shown by the RDF analyses. Additionally, analysis of free volume elements suggests that the ability of TR polymers to maintain their interconnected microstructure and resistance to CO2-induced plasticization at high pressures leads also to higher diffusion and hence permeation performances and as a result, make them promising materials in gas separation applications.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 108-32-7 help many people in the next few years. HPLC of Formula: C4H6O3.

Hydrogen bonding interactions induced excited state proton transfer and fluoride anion sensing mechanism for 2-(3,5-dichloro-2,6-dihydroxy-phenyl)-benzoxazole-5-carboxylicacid

The present work explores and reports photo-induced behavior and excited state intramolecular proton transfer (ESIPT) process for the novel 2-(3,5-dichloro-2,6-dihydroxy-phenyl)-benzoxazole-5-carboxylicacid (DICH) compound. Our theoretical investigation implies that two intramolecular hydrogen bonds (O1H2 center dot center dot center dot N3 or O4H5 center dot center dot center dot O6) of DICH form are strengthening in the first excited state by comparing bond lengths, bond angles, and infrared (IR) spectra, which may facilitate the ESIPT process effectively. Particularly, the changes of O1H2 center dot center dot center dot N3 are bigger than O4H5 center dot center dot center dot O6, which demonstrates that the ESIPT is more likely to happen along with O1H2 center dot center dot center dot N3. Within the framework of MOs analysis, intramolecular charge transfer phenomenon can be found, which could be a reasonable evidence for confirming the occurrence of the ESPT process in the S-1 state. We theoretically construct the potential energy curves for DICH system based on fixing both O1H2 and O4H5 bond lengths and optimizing structures in both S-0 and S-1 states. Through the comparisons of potential barriers among stable configurations, we confirm the S-1-state DICH-PT1 (proton-transfer tautomer along with O1H2 center dot center dot center dot N3) should be the most reasonable configuration ascribed to previous experimental emission peak. Furthermore, we also predict and explain the fluoride-sensing mechanism for DICH system that the deprotonation reaction bringing from fluoride anion inhibits the initial ESIPT process of DICH, which results in the novel changes of ultraviolet-visible (UV-Vis) spectra that plays the roles in fluorescence response. We sincerely hope this work could provide essential insights into the design and function of ESIPT as well as florescence sensor for optoelectronic applications.
