A series of liquid-crystalline (LC) thermosetting monomers containing benzoxazole (BO) units were synthesized to evaluate the thermal conductivities (lambda) of their cured resins. A BO-containing bisnadiimide system showed LC behavior during the heating process. However, the thermal cure of the bisnadiimide provided a film without optical anisotropy; consequently, the cured film exhibited normal levels of thermal diffusivity (alpha) and thermal conductivity (lambda). The disappearance of the optically anisotropic ordered structures during thermal curing is likely related to the temperature gaps between the cure reaction ranges and LC ranges (T-cure-T-LC gap). In addition, epoxy resins consisting of bisepoxides and BO-containing diamines were investigated because of their high flexibility in terms of molecular design that can be used to reduce the T-cure-T-LC gap. The combination of a terephthalylidene-type bisepoxide and BO-containing diamine with a controlled flexible chain length resulted in the smallest T-cure-T-LC gap among the epoxy resin systems examined herein. The cured epoxy resin film exhibited an appreciably increased lambda value (0.257 W m(-1) K-1) in the Z direction. This indicated the importance of the T-cure-T-LC gap for enhancing the alpha and lambda values of the cured films. This epoxy resin system was cured under a continuous DC electric field during polarizing optical microscopy. A prompt response with deformation of the LC domains was observed in harmony with temporal ON/OFF switching of the DC power supply. As expected, the cured film exhibited a significantly enhanced lambda value (0.488 W m(-1) K-1) in the Z direction.

Long-term potentiation (LTP) is a molecular basis of memory formation. Here, we demonstrate that LTP critically depends on fructose 1,6-bisphosphatase 2 (Fbp2)-a glyconeogenic enzyme and moonlighting protein protecting mitochondria against stress. We show that LTP induction regulates Fbp2 association with neuronal mitochondria and Camk2 and that the Fbp2-Camk2 interaction correlates with Camk2 autophosphorylation. Silencing of Fbp2 expression or simultaneous inhibition and tetramerization of the enzyme with a synthetic effector mimicking the action of physiological inhibitors (NAD(+)and AMP) abolishes Camk2 autoactivation and blocks formation of the early phase of LTP and expression of the late phase LTP markers. Astrocyte-derived lactate reduces NAD(+)/NADH ratio in neurons and thus diminishes the pool of tetrameric and increases the fraction of dimeric Fbp2. We therefore hypothesize that this NAD(+)-level-dependent increase of the Fbp2 dimer/tetramer ratio might be a crucial mechanism in which astrocyte-neuron lactate shuttle stimulates LTP formation.

The approach to the directed synthesis of lanthanide aromatic carboxylates – precursors to the electro-luminescent materials, – was proposed, namely the conjugation length increase and heteroatom introduction in the appropriate position in combination with the neutral ligand introduction. This resulted in the isolation of a series of new lanthanide complexes, among which the highest electrolurninescence efficiency was obtained for mixed-ligand europium benzothiazole-2-carboxylate with bathophenanthroline in a solution-processed OLED. The peculiarities of energy transfer processes allowed obtaining luminescence thermometer materials based on this system, which demontrated the sensitivity of 2.8%/K in the physiological range.

Herein, we have carried out a structural optimization campaign to discover the novel anti-tumor agents with our previously screened YQY-26 as the hit compound. A library of thirty-seven 6-amide-2-aryl benzoxazole/benzimidazole derivatives has been designed and synthesized based on the highly conserved active site of VEGFR-2. Several title compounds exhibited selective inhibitory activities against VEGFR-2 than EGFR kinases, which also displayed selective anti-proliferation potency against the HUVEC and HepG2 than the A549 and MDA-MB-231 cancer cell lines. The newly synthesized compounds were evaluated for anti-angiogenesis capability by chick chorioallantoic membrane (CAM) assay. Among them, compounds 9d showed the most potent anti-angiogenesis ability (79% inhibition at 10 nM/eggs), the efficient cytotoxic activities (in vitro against the HUVEC and HepG2 cell lines with IC50 values of 1.47 and 2.57 mu M, respectively), and excellent VEGFR-2 kinase inhibition (IC50 = 0.051 mu M). The molecular docking analysis revealed that compound 9d is a Type 11 inhibitor of VEGFR-2 kinase. These results indicated that the 6-amide-2-arylbenzoxazole and 6-amide-2-aryl benzimidazole derivatives are promising inhibitors of VEGFR-2 kinase for the potential treatment of anti-angiogenesis.

New discoveries in chemical research and development in 2021.

The diamine monomer, 9,9-bis[4-(4-amino-3-hydroxylphenoxy)phenyl] fluorene (bis-AHPPF) was successfully synthesized according to our modified method. A series of hydroxyl-containing poly(ether-imide)s (HPEIs) were prepared by polycondensation of the bis-AHPPF diamine with six kinds of dianhydrides, including 1,2,3,4-cyclobutanetetracarboxylic dianhydride (CBDA), pyromellitic dianhydride (PMDA), 3,3 ‘,4,4 ‘-biphenyl tetracarboxylic diandhydride (BPDA), 3,3 ‘,4,4 ‘-oxydiphthalic anhydride (ODPA), 3,3 ‘,4,4 ‘-benzophenonetetracarboxylic dianhydride (BTDA) and 4,4 ‘-(hexafluoroisopropylidine)diphtalic anhydride (6FDA) followed by thermal imidization. The corresponding thermally rearranged (TR) membranes were obtained by solid state thermal treatment at high temperature under a nitrogen atmosphere. The chemical structure, and physical, thermal and mechanical properties of the HPEI precursors were characterized. The effects of heat treatment temperature and dianhydrides on the gas transport properties of the poly(ether-benzoxazole) (PEBO) membranes were also investigated. It was found that these HPEIs showed excellent thermal and mechanical properties. All the HPEI precursors underwent thermal conversion in a N-2 atmosphere with low rearrangement temperatures. The gas permeabilities of the PEBO membranes increased with the increase of thermal treatment temperature. When HPEI-6FDA was treated at 450 degrees C for 1 h, the H-2, CO2, O-2 and N-2 permeabilities of the membrane reached 239.6, 196.04, 46.41 and 9.25 Barrers coupled with a O-2/N-2 selectivity of 5.02 and a CO2/N-2 selectivity of 21.19. In six TR-PEBOs, PEBO-6FDA exhibited the lowest rearrangement temperature and largest gas permeabilities. Therefore, thermally rearranged membranes from bis-AHPPF-based HPEIs are expected to be promising materials for gas separation.

SYNTHESIS, CHARACTERIZATION AND BIOLOGICAL EVALUATION OF SOME 2-ARYLBENZOXAZOLE ACETIC ACID DERIVATIVES AS PROMISING ANTICANCER AGENTS

The synthesis of a series of 2-arylbenzoxazole compounds possessing a cytotoxic activity as potential anticancer agents was achieved. Oxidative coupling of benzaldehyde with o-aminophenol utilizing lead tetraacelate approach was used to realize the synthesis of compounds 1-11. The cytotoxicity of 1-11 was screened against breast cancer cell line MCF-7 and human colon cancer cell line HCT-116 utilizing doxorubicin as a reference drug. Among these compounds, 2-(3-benzyloxyphenyl)benzoxazole-5-acetic acid (5) and 2-(4-methoxyphenyl)benzoxazol-5-acetic acid (10), were found to be promising cytotoxic compounds against the MCF-7 cell line. In addition, this study showed that the presence of an acetic acid group at position 5 of the benzoxazole nucleus enhances the activity. Moreover, we noticed that the presence of an oxygen atom directly linked to the phenyl substituent improves activity as well. These results offer a new benzoxazole based template to design and develop novel antineoplastic agents.

We describe the synthesis of 3-carbamoylpropanoic acid derivatives and their evaluation as human PHD-2 inhibitors. MS assays indicated that derivatives with a 3-carbamoylpropanoic acids-containing benzoxazole moiety are inhibitors of PHD-2 with IC50 values of 2.24 mu M and 1.32 mu M, respectively. However, neither the acids nor their respective ethyl esters were observed to upregulate HIF-1 alpha levels in cells.

Highly emissive heterocyclic alanines bearing a benzo[d]oxazolyl unit functionalised with pyrrole and imidazole at the side chain were synthesised and evaluated as fluorimetric chemosensors for different anions and metal cations. The results obtained by UV-Vis and fluorescence titrations as well as H-1 NMR titrations indicate that there is a strong interaction through the donor N and O atoms at the side chain of the benzoxazolyl-alanines, with high selectivity towards Cu2+ and Pd2+ in a ligand-to-metal complex with 1:2 stoichiometry, and association constants were calculated for some ions.
