Fusing acridine and benzofuran/benzothiophene as a novel hybrid donor for high-performance and low efficiency roll-off TADF OLEDs

Two novel acridine-benzofuran/benzothiophene hybrid donors of 34BxAc (x = F, 34BFAc: 13,13-dimethyl-8,13-dihydrobenzofuro[3,2-a]acridine; x = T, 34BTAc: 13,13-dimethyl-8,13-dihydrobenzo[4,5]thieno[3,2-a]acridine) were developed as aromatic fused donors by combining dimethyl acridine (Ac) with benzofuran and benzothiophene, respectively. As a comparison, the hybrid donors of 12BxAc (x = F, 12BFAc: 5,5-dimethyl-5,13-dihydrobenzofuro[3,2-c]acridine; x = T, 12BTAc: 5,5-dimethyl-5,13-dihydrobenzofuro[3,2-c]acridine) were also prepared. By attaching the TPPM (2,4,6-triphenylpyrimidine) acceptor to these fused hybrid donors (12BFAc, 12BTAc, 34BFAc and 34BTAc), 12BxAc-PM (12FAc-PM and 12BTAc-PM) and 34BxAc-PM (34BFAc-PM and 34BTAc-PM) were further designed and synthesized. It was revealed that 34BxAc-PM was better than 12BxAc-PM at shrinking the singlet-triplet energy gap and decay lifetime, and increasing the photoluminescence quantum yield. The sky-blue thermally activated delayed fluorescent organic light-emitting diodes (OLEDs) with 12BFAc-PM as a dopant just showed a maximum external quantum efficiency (EQE) of 12.9% and a CIEx,y of (0.16, 0.29). The 12BTAc-PM-based device achieved a maximum EQE of 25.6%, however, the efficiency roll-off was relatively serious. In contrast, high-performance and low efficiency roll-off OLEDs can be developed using 34BxAc-PM. For instance, the 34BFAc-PM-based device realized a maximum EQE of 27.7%, and still a high EQE of 24.6% at 1000 cd m(-2) and 19.6 cd m(-2) at 5000 cd m(-2), respectively, indicative of the superiorities of the novel donors (34BFAc and 34BTAc).

Tuning the organic persistent room-temperature phosphorescence through aggregated states

Persistent (long-lived) room-temperature phosphorescence (pRTP) materials from a single molecule with different polymorphs are rarely reported and need to be further investigated. In the current work, we have designed and synthesized an asymmetric molecule composed of carbazole and benzofuran based D-A-D ‘ pRTP materials, i.e., (4-(9H-carbazol-9-yl)phenyl)(dibenzo[b,d]furan-2-yl)methanone (DBF-BZ-Cz). The compound DBF-BZ-Cz exhibits different polymorphs with various pRTP properties, including a difference in their phosphorescence color and lifetimes. The tuning of long-lived phosphorescence of a simple compound through controlling the aggregated state is shown for the first time. The color of its pRTP changed from light-yellow to orange, while its pRTP lifetime shifted from 0.76 to 0.32 s. Furthermore, it is noted that a clear negative correlation between the fractional free volume (FFV) in the crystals and the pRTP lifetime can be drawn out for the ketone derivatives. The current work demonstrates that the pRTP properties can be tuned in one single compound via controlling the aggregated states, which provides a new strategy for the investigation and application of organic long-lived phosphorescence.

Discovery of novel benzofuran-based compounds with neuroprotective and immunomodulatory properties for Alzheimer’s disease treatment

To address the multifactorial nature of Alzheimer’s Disease (AD), a multi-target-directed ligand approach was herein developed. As a follow-up of our previous studies, a small library of newly designed 2-arylbenzofuran derivatives was evaluated towards cholinesterases and cannabinoid receptors. The two most promising compounds, 8 and 10, were then assessed for their neuroprotective activity and for their ability to modulate the microglial phenotype. Compound 8 emerged as able to fight AD from several directions: it restored the cholinergic system by inhibiting butyrylcholinesterase, showed neuroprotective activity against A beta(1-42) oligomers, was a potent and selective CB2 ligand and had immunomodulatory effects, switching microglia from the pro-inflammatory M1 to the neuroprotective M2 phenotype. Derivative 10 was a potent CB2 inverse agonist with promising immunomodulatory properties and could be considered as a tool for investigating the role of CB2 receptors and for developing potential immunomodulating drugs addressing the endocannabinoid system.

Amino acids conjugated quinazolinone-Schiff’s bases as potential antimicrobial agents: Synthesis, SAR and molecular docking studies

A series of amino acids conjugated quinazolinone-Schiff’s bases were synthesized and characterized by analytical and spectroscopic methods. All the synthesized analogues (8-43) and the intermediates (1-7) were screened for their in vitro antibacterial and antifungal activities. In antimicrobial activity, compounds 12-16, 21-25, 30-34 and 39-43 showed excellent antibacterial activity which is better than the antibacterial standard Streptomycin. Compounds 15, 23-25, 30-34, 36 and 38-43 showed excellent antifungal activities which is more active than the reference antifungal drug Bavistin. Further, to understand the correlation of biological activity with that of drug-receptor interaction, molecular docking was performed on active site ofglucosamine-6-Phosphate (GlcN-6-P) synthase (PDB ID: 2VF5) which showed good binding profile. Molecular docking studies and Preliminary structure-activity (SAR) relationship revealed that the tryptophan and phenylalanine conjugated quinazolinones with electron donating groups (OH and OCH3) were found to be excellent antimicrobial activities which is better than the glycine and alanine conjugated derivatives. This may be explained by the contribution of aromaticity and hydrophobicity of amino acids. Among the series, compounds 41 and 43 showed the highest docking scores for antimicrobial activity. The conjugation plays a major role in improving the biological activities of those compounds.

Investigation of anti-inflammatory and toxicity effects of mangrove-derived Streptomyces rochei strain VITGAP173

Mangrove ecosystems generate the major biodiversity hotspots of actinobacteria. Among the actinobacteria, Streptomyces species are the prolific producers of bioactive natural products. In this study, with research efforts to discover biopotential compounds from marine actinobacteria, 41 actinobacterial strains were isolated from sediment soil sample of Indian mangrove regions. The phylogeny prediction using the 16S rRNA gene sequences revealed that the isolates were related to Streptomyces. Isolates were further screened based on a two-step process wherein the first step, around nine strains, unveiled the presence of type 1 polyketide synthase gene and dTDP-glucose 4,6-dehydratase gene through polymerase chain reaction. As the second step of the screening process, cell viability assay was performed in RAW264.7 cells to assess the toxicity of extracts. Among all the isolates, Streptomyces rochei strain VITGAP173 was subjected to further analysis. To explore the bioactivities, the organic solvent extraction method was utilized to extract the broth culture of VITGAP173. Inhibition of nitric oxide and cyclooxygenase enzymes upon lipopolysaccharide-induced inflammation were utilized to evaluate the anti-inflammatory efficacy, and the results showed the potency of VITGAP173 in a dose-dependent manner. The extract significantly suppressed the messenger RNA levels of the inflammatory mediators such as tumor necrosis factor-alpha and interleukin-6 induced by lipopolysaccharide in RAW264.7 macrophages. The presence of several chemical constituents was identified through gas chromatography-mass spectrometry analysis of VITGAP173 extract. To achieve the toxicity analysis, oral administration of VITGAP173 extract in Wistar albino rats was carried out to investigate the biochemical parameters, histopathology which revealed its nontoxic nature.
