Iwaki, Yuzo published the artcileTowards a TREK-1/2 (TWIK-Related K+ Channel 1 and 2) dual activator tool compound: Multi-dimensional optimization of BL-1249, Formula: C7H6N2, the main research area is TREK1 TREK2 potassium ion channel activator; Activator; K(2P) channel; Potassium ion channel; TREK-1; TREK-2.

This letter describes a focused, multi-dimensional optimization campaign around BL-1249, a fenamate class non-steroidal anti-inflammatory and a known activator of the K2P potassium channels TREK-1 (K2P2.1) and TREK-2 (K2P10.1). While BL-1249 has been widely profiled in vitro as a dual TREK-1/2 activator, poor physicochem. and DMPK properties have precluded a deeper understanding of the therapeutic potential of these key K2P channels across a broad spectrum of peripheral and central human disease. Here, we report multi-dimensional SAR that led to a novel TREK-1/2 dual activator chemotype, exemplified by ONO-2960632/VU6011992, with improved DMPK properties, representing a new lead for further optimization towards robust in vivo tool compounds

Bhardwaj, Vijay Kumar published the artcileComputer simulation to identify selective inhibitor for human phosphodiesterase10A, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is phosphodiesterase computer simulation mol docking.

Phosphodiesterases (PDEs) play an important function in transduction of cellular signals by modulating the activation of G-proteins by hydrolyzing cAMP and cGMP. PDE10A has emerged as an inhibitory target for development of effective therapeutics against various disorders such as schizophrenia, psychosis, Huntington disease, and other disorders related to the central nervous system. We utilized various computational methods such as mol. docking, mol. dynamic simulations, and MM-PBSA to find a more potent and selective PDE10A inhibitor compared to papaverine, which is a known standard inhibitor of PDE10A. Mol. docking of papaverine and twenty-eight in house synthesized 3-Methylenisoindolin-1-one based mols. provided two potential lead mols. (mol. #3 and mol. #28), which could be developed as potent PDE10A inhibitors. However, mol. #28 was excluded from further studies due to its cross reactivity with other PDE isoforms. Mol. dynamics and MM-PBSA techniques were used to further analyze the mol. docking results. Mol. #3 binds to the conserved substrate recognizing residue (Gln726) and also fits into the selectivity pocket by anchoring to the hydrophobic residue Tyr693. This study provides a promising candidate mol. that could be developed as a more potent and selective inhibitor of PDE10A.

Liu, Limin published the artcileGroup IIA alkaline-earth metal phthalocyanines: Synthesis, photoluminescence and singlet oxygen formation, Computed Properties of 91-15-6, the main research area is metallophthalocyanine fluorescence lifetime singlet oxygen formation.

We have synthesized Group IIA alk.-earth metal phthalocyanine (PC) complexes (BePC, MgPC, CaPC, SrPC, BaPC) using four different methods to study their photoluminescence and singlet oxygen photosensitizing properties. Their UV-Vis electronic absorption, fluorescence emission and excitation spectra, fluorescence quantum yields and lifetimes, as well as singlet oxygen formation quantum yields have been measured. The results reveal that alkali-earth metal PCs (BePC, MgPC, CaPC, SrPC, and BaPC) have high fluorescence quantum yields (0.50 to 0.70) and long fluorescence lifetimes (7.1 to 7.9 ns). SrPC, and BaPC also show high quantum yield of singlet oxygen formation (0.40 to 0.50). Therefore, alk.-earth metal phthalocyanines are appealing fluorescent sensors and singlet oxygen photosensitizers for photodynamic therapy of tumors.

Hirashima, Akinori published the artcileThe pheromone production of female Plodia interpunctella is inhibited by tyraminergic antagonists, Computed Properties of 87150-13-8, the main research area is sex pheromone production inhibition tyraminergic antagonist moth; Plodia sex pheromone production inhibition tyraminergic antagonist.

Several compounds were found to suppress the calling behavior and in vitro pheromone biosynthesis of the Indian meal moth, Plodia interpunctella. The compounds were screened by means of a calling-behavior bioassay with female P. interpunctella. Five derivatives with activities in the nanomolar range were identified, in order of decreasing pheromonostatic activity: 4-hydroxybenzaldehyde semicarbazone > 5-(4-methoxyphenyl)-1,3-oxazole > 5-[4-(tert-butyl)phenyl]-1,3-oxazole > 5-(3-methoxyphenyl)-1,3-oxazole > 5-(4-cyanophenyl)-1,3-oxazole. These compounds also showed in vitro inhibitory activity in intracellular de novo pheromone biosynthesis, as determined with isolated pheromone-gland preparations that incorporated [1-14C]sodium acetate in the presence of the so-called pheromone-biosynthesis-activating neuropeptide (PBAN). The non-additive effect of the inhibitor with antagonist (yohimbine) for the tyramine (TA) receptor suggests that it could be a tyraminergic antagonist. Three-dimensional (3D) computer models were built from a set of compounds Among the common-featured models generated by the program Catalyst/HipHop, aromatic-ring (AR) and H-bond-acceptor-lipophilic (HBA1) features were considered to be essential for inhibitory activity in the calling behavior and in vitro pheromone biosynthesis. Active compounds, including yohimbine, mapped well onto all the AR and HBA1 features of the hypothesis. Less-active compounds were shown to be unable to achieve an energetically favorable conformation, consistent with our 3D common-feature pharmacophore models. The present hypothesis demonstrates that calling behavior and PBAN-stimulated incorporation of radioactivity are inhibited by tyraminergic antagonists.

Xiao, Hang published the artcileA High-Mechanical-Strength Carbon/Graphene Porous Composite with Improved EMI Shielding Derived from High Nitrogen-Containing Bio-based Adenine-Containing Phthalonitrile Resin, COA of Formula: C8H4N2, the main research area is carbon graphene porous composite EMI shielding mech property.

Abstract: Nitrogen-doped porous graphene/adenine-containing phthalonitrile (graphene/ADCN) carbon composites with excellent mech. properties and electromagnetic interference (EMI) shielding performance were prepared by the high-energy ball milling molding-sintering method. The structure, morphol., elec. conductivity, dielec. properties, EMI shielding performance, and mech. properties were characterized. The results show that the introduction of the dipole effect can confer improved elec. conductivity and EMI shielding properties to graphene/ADCN carbon composites. The porous structure increases the multiple reflections and improves the EMI performance. As a mech. reinforcement phase, graphene was introduced to maintain the porous structure and improve the mech. properties. The EMI performance of graphene/ADCN carbon composites reached 47dB (7.5wt.% graphene) with only 0.94 mm thickness. Meanwhile, the maximum bending stress reached 292 MPa, and the maximum compressive stress reached 143 MPa. Graphical Abstract: [graphic not available: see fulltext].

Moringa oleifera Lam. is a fast-growing deciduous tree native to the subcontinent with a wide array of uses. It is used as food plant by human and animals. Since it contains beneficial higher calcium, vitamin A, vitamin C, protein, potassium and iron contents, it is also used to treat malnutrition in children. The present study is conducted for comprehensive phytochem. profiling via total bioactive contents and ultra-high performance liquid chromatog. (UHPLC-MS) analyses, and biol. profiling by determining the antioxidant potential via DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2-azino-bis 3-ethylbenzothiazoline-6-sulfonic acid), FRAP (ferric reducing antioxidant power), CUPRAC (cupric reducing antioxidant power), phosphomolybdenum and metal chelation assays. In addition, α-amylase, α-glucosidase, acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and tyrosinase inhibition assays were also performed. Multivariate statistical anal. was used to investigate the relationship between biol. activities and total bioactive content of the extracts Chem. profiling showed that total phenolic contents are present in highest concentrations in Et acetate extracts of the aerial parts and seed. Further total bioactive contents were correlated with their optimum anti-oxidant capacities for ABTS, FRAP and CUPRAC. Altogether 67 phytochems. were identified from aerial parts of the plant and its seed with major classes as phenolics, flavonoids, sesquiterpenoids and alkaloids. The Et acetate extract of seed showed good inhibition of AChE (2.77 mg GALAE/g extract) and BChE (8.05 mg GALAE/g extract) followed by the inhibition potential of water extract as 8.34 mg GALAE/g extract The Et acetate extract also showed most significant (61.93 mg-KAE/g) tyrosinase inhibitory activity. The hexane extract of seed showed good inhibition of α-glucosidase (6.32 mmol ACAE/g extract) and α-amylase (0.47 mmol ACAE/g extract). In silico docking studies were performed, where two herbimycin and prekinamycin showed good binding affinity with all the enzymes. It can be concluded that the presence of complex phytochems. with multi-functional potential distinguishes Moringa oleifera Lam. as a promising source of health-promoting component and recommended its use in biopharmaceutical industries.
