Liu, Fan published the artcileHole Transport Materials Based on 6,12-Dihydroindeno[1,2-b]fluorine with Different Periphery Groups: A New Strategy for Dopant-Free Perovskite Solar Cells, Quality Control of 111865-47-5, the publication is Advanced Functional Materials (2019), 29(24), n/a, database is CAplus.

Although several hole-transporting materials (HTMs) have been designed to obtain perovskite solar cells (PSCs) devices with high performance, the dopant-free HTMs for efficient and stable PSCs remain rare. Herein, a rigid planar 6,12-dihydroindeno[1,2-b]fluorine (IDF) core with different numbers of bulky periphery groups to construct dopant-free HTMs of IDF-SFXPh, IDF-DiDPA, and IDF-TeDPA is modified. Thanks to the contributions of the planar IDF core and the twisted SFX periphery groups, the dopant-free IDF-SFXPh-based PSCs device achieves a device performance of 17.6%, comparable to the doped 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD)-based device (17.6%), with much enhanced device stability under glovebox and ambient conditions.

Chen, Ying published the artcileStructure-activity relationship studies of (E)-3,4-dihydroxystyryl alkyl sulfones as novel neuroprotective agents based on improved antioxidant, anti-inflammatory activities and BBB permeability, Name: (2-Bromoethyl)cyclopentane, the publication is European Journal of Medicinal Chemistry (2019), 420-433, database is CAplus and MEDLINE.

(E)-3,4-dihydroxystyryl alkyl sulfones I [n = 0, 1, 2; R = Et, Pr, Bu, etc.], as new analogs of neurodegenerative agents, were designed and synthesized. The biol. results demonstrated that most of the target compounds preserved antioxidant and anti-inflammatory potency in scavenging reactive free radicals, protecting neuronal cells against neurotoxins such as H₂O₂, 6-hydroxydopamine and inhibiting lipopolysaccharide (LPS)-induced over-production of NO. Among these compounds, I [n = 2; R = cyclopentyl] exhibited prominent antioxidant activity at low concentration (2.5 μM) in H₂O₂ model (cell viability = 94.5%). In addition, I [n = 2; R = cyclopentyl] (IC₅₀ = 1.6 μM) displayed better anti-inflammatory activity than that of lead compound 1 (IC₅₀ = 13.4 μM). In view of the outstanding performance of I [n = 2; R = cyclopentyl], the apoptotic rates of H₂O₂-damaged PC12 cells were detected by Annexin V-FITC/PI assay. I [n = 2; R = cyclopentyl] showed higher potency in inhibition of apoptosis than 1 at low concentration (2.5 μM), consisting with the antioxidant and anti-inflammatory models. Furthermore, with the predicted CNS (+) blood-brain barrier (BBB) permeability (Pe = 6.84 x 10^-6 cm s^-1), low cytotoxicity and favorable physiochem. properties based on calculation, compound I [n = 2; R = cyclopentyl] can be further developed as a potential multifunctional neuroprotective agent.

Similarly 1-chloro-6-heptyne (VIII) was prepared in 70% yield from Na₂C₂ and II, 73% 1-chloro-5-heptyne (IX) from NaCCMe and I, and 1-chloro-4-heptyne (X) in 30% yield (addition of NaCCEt to Cl (CH₂)₃Br gave no better yield). This type of reaction did not work with Cl(CH₂)₂Br. As IX and X were impure, another method was tried. NaNH₂ (78 g.) was stirred 30 min. with 205 g. 1-chloro-4-pentyne in 2 l. liquid NH₃, and then 218 g. EtBr added during 3 h.; distillation gave 17% (45 g.) crude X containing traces of a terminal alkyne, possibly VIII.

No XII was obtained when 1 equivalent C₅H₅N was used. Similarly IV gave 63% 1-bromo-2-hexyne (XIII), b₈₀ 97-8°, n_D²⁵ 1.4884, and also 12% HBr addn, product, probably 1,3-dibromo-2-hexene, b₂₅ 100°, b₂ 62°, n_D²⁵ 1.5235. The yield of crude 1-bromo-3-heptyne from V was only 41%. Both Br compounds XII and XIII gave immediate precipitates with alc. AgNO₃ whereas the Cl compound XI reacted only slowly or on warming. Addition of 3.2 mol Na₂C₂ in 1.5 l. liquid NH₃ during 1 h. to 1050 g. Br(CH₂)₅Br, 500 cc. Et₂O, and 1000 cc. NH₃, then 2 h. stirring, etc., gave 27% 1-bromo-6-heptyne (XIV), b₂₀ 92°, n_D²⁵ 1.4750. Because of difficulties in the conversion of XII to the nitrile, N. and W. considered the addition of Br to the triple bond and its later removal; they did add 80 g. Br to 56 g. III in CCl₄ at 0° to obtain 81% 2,3-dibromo-2-hepten-1-ol (XV), b₄ 113-15°; 3,5-dinitrobenzoate, m. 84-5°. XV was then converted to 87% 1,2,3-tribromo-2-heptene, b₄ 112-14°, b₂ 96°, n_D²⁵ 1.5540.

Other yields were 0-90%, careful temperature control being very important. XII or XI and aqueous KCN would not give XVI. 1-Cyano-3-heptyne (XVII) was prepared in 50% yield from the acid via the amide and dehydration of the latter with P₂O₅. Acetylenic acids: Except for XVII, the nitriles were hydrolyzed in boiling aqueous alc. 10% KOH until NH₃ evolution ceased. Data are given in the table, 5-, 6-, and 7-octynoic acids being prepared in 90% yields. 3-Octynoic acid, prepared in 74% yield by addition of HCl gas to 140 g. XVI in 250 cc. MeOH and 25 cc.

XVI was brominated as XV above to 50% 1-cyano-2,3-dibromo-2-heptene, b₄ 118°. Hydrolysis of 14 g. with 20 cc. concentrated H₂SO₄ 15 min. at 80°, then 3 h. at room temperature, gave only 47% 3,4-dibromo-3-octenamide. m. 130-1°. 4- (XVIII) and 5-Octynoic acids were prepared by decarboxylation of the corresponding malonic esters. Thus, 280 g. XIII added to 41.5 g. Na and 320 g. Et malonate in 1.5 l.

Pironetin is an α-tubulin-binding natural product with potent antiproliferative activity against several cancer cell lines that inhibits cell division by forming a covalent adduct with α-tubulin via a Michael addition into the natural product’s α,β-unsaturated lactone. We designed and prepared analogs carrying electron-withdrawing groups at the α-position (C2) of the α,β-unsaturated lactone with the goal to generate potent and selective binding analogs. We prepared derivatives I (R = F, Me, Cl, Br, Ph) containing halogens, a Ph, and a Me group at the C2 position to evaluate the structure-activity relationship at this position. Testing of the analogs in ovarian cancer cell lines demonstrated 100-1000-fold decreased antiproliferative activity.

Histone lysine demethylases (KDMs) are of critical importance in the epigenetic regulation of gene expression, yet there are few selective, cell-permeable inhibitors or suitable tool compounds for these enzymes. The authors describe the discovery of a new class of inhibitor that is highly potent towards the histone lysine demethylases KDM2A/7A. A modular synthetic approach was used to explore the chem. space and accelerate the investigation of key structure-activity relationships, leading to the development of a small mol. with around 75-fold selectivity towards KDM2A/7A vs. other KDMs, as well as cellular activity at low micromolar concentrations

McKenzie, Blayne M. published the artcileMetallo-Responsive Liquid Crystalline Monomers and Polymers, Application In Synthesis of 1036461-93-4, the publication is Chemistry of Materials (2011), 23(15), 3525-3533, database is CAplus.

A series of liquid crystalline ligand-containing monomers with chemo-responsive properties was prepared and studied. These mols. are functionalized derivatives of the 2,6-bisbenzimidazolylpyridine (Bip) ligand. Tailoring the size of the aromatic core and the length of two pairs of alkyl substituents allows the preparation of mesogens with a range of tunable thermal liquid crystalline transitions and phases. The binding of lanthanide- and/or transition metal salts to the ligand containing mesogens results in a transition from a liquid crystalline to an isotropic state. Acyclic diene metathesis of the monomers yielded either oligomers or polymers, dictated by whether the alkene is either terminal or nonterminal, resp. Both oligomers and polymers exhibit enantiotropic liquid crystalline behavior and become isotropic in the presence of metal ions.

The tristriazolotriazine (TTT) N-heterocycle, despite being a relatively new mesogenic core for use in discotic liquid crystals, has already demonstrated its importance and promising characteristics. In this work, we extended the knowledge about the TTT, increasing the core size with alkoxybenzoate units, as well as evaluating how the expansion and number of peripheral chains affected the thermal and photophys. properties, both in solution and spin-coated films. Their thermal behavior and self-assembly were studied by differential scanning calorimetry, polarizing optical microscopy and X-ray diffraction with synchrotron radiation, while the photophysics was investigated by UV-Vis absorption and fluorescence spectroscopy. The results show that, despite a considerable decrease in the fluorescence quantum yield with the core expansion, the mesomorphic properties are significantly enhanced, with two products showing Colh mesophase at room temperature, with large range of mesomorphism and very good thermal stability. It was also demonstrated how structural changes affected the self-assembly properties.
