Effect of chemical structure of benzofuran derivatives and reaction conditions on enantioselective properties of Aureobasidium pullulans microorganism contained in Boni Protect antifungal agent

Bioorganic asymmetric reduction of carbonyl compounds is one of the most important fundamental and practical reactions for producing chiral alcohols. The stereoselective bioreduction of prochiral ketones of benzofuran derivatives in the presence of yeast-like fungus Aureobasidium pullulans contained in the antifungal Boni Protect agent was studied. Biotransformations were carried out under moderate conditions in an aqueous and two-phase system and without multiplication of the bioreagent. Despite similar chemical structure, each of the used ketone has been reduced with varying efficiency and selectivity. One of the reasons for these results is the presence of a whole set of oxidoreductases in A. pullulans cells that are sensitive to the smallest changes in the structure of prochiral substrate. The unsymmetrical methyl ketones were biotransformed with the highest selectivity. Aureobasidium pullulans microorganism is less effective in the reduction of unsymmetrical halomethyl ketones. The presence of a heteroatom in the alkyl group significantly decreases the selectivity of the process. Finally, as a result of the preferred hydride ion transfer from the dihydropyridine ring of the cofactor to the carbonyl double bond on the re side, secondary alcohols of the S and R configuration were obtained with moderate to high enantioselectivity (55-99%).

Design, synthesis, in vitro and in silico studies of 2, 3-diaryl benzofuran derivatives as antitubercular agents

As a part of our drug discovery program for anti-tubercular agents, a total of seventeen 2, 3-diaryl benzofuran hybrids were designed, synthesized and screened for their anti-tubercular potential against Mycobacterium tuberculosis H37Ra avirulent strain. Out of seventeen, four derivatives showed significant activity against M. tuberculosis H37Ra avirulent strain (ATCC 25177) with MIC value ranging from 12.5 to 50 mu g/mL but out of four, one derivative (9E) was significantly active (MIC 12.5 mu g/mL), which was further supported by the molecular docking energy (-8.4 kcal/mol) with respect to the first line anti-tubercular drug, isoniazid (-6.2 kcal/mol) on the target Polyketide Synthase-13. All the derivatives were also evaluated for their cytotoxicity against the normal lung cell line L-132 by the MTT assay and no toxicity was observed up to 27.4 mu g/mL concentration. This report on the antitubercular potential of benzofuran derivatives may be of great help in anti-tubercular drug development.

Double-Carboxylation of Two C-H Bonds in 2-Alkylheteroarenes Using LiO-t-Bu/CsF

We describe the double-carboxylation of two C-H bonds (i.e., at the benzylic and the beta-positions) in 2-alkylheteroarenes using a combination of LiO-t-Bu and CsF. A diverse range of substrates, namely benzothiophene, thiophene, benzofuran, furan, and indole derivatives, are efficiently converted into the doubly carboxylated products. A variety of functionalities (i.e., methyl, methoxy, halogen, cyano, ester, ketone, and amide moieties) are well tolerated.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Cis-Dihydroxylation of Tricyclic Arenes and Heteroarenes Catalyzed by Toluene Dioxygenase: A Molecular Docking Study and Experimental Validation

Molecular docking studies of toluene dioxygenase led to the prediction that angular and lateral cis-dihydroxylation of tricyclic arene and heteroarene substrates could occur. Biotransformations of biphenylene, dibenzofuran, carbazole and dibenzothiophene, using Pseudomonas putida UV4 whole cells, expressing toluene dioxygenase, confirmed that both angular and lateral cis-dihydroxylation had occurred in the predicted regioselective and stereoselective manner. The toluene dioxygenase-catalysed (Pseudomonas putida UV4) biotransformation of dibenzofuran was optimized, to produce 1,2-dihydrodibenzofuran-1,2-diol as the major metabolite in excellent yield. 2-Hydroxydibenzofuran, resulting from dehydration of 1,2-dihydrodibenzofuran-1,2-diol, was also found to undergo cis- dihydroxylation to give a very minor cis-dihydrodiol metabolite. The enantiopurity (>98% ee) and (1R,2S) absolute configuration of the major dibenzofuran cis -dihydrodiol was rigorously established by catalytic hydrogenation and formation of methoxy(trifluoromethyl)phenylacetate derivatives and by X-ray crystallography of an epoxide derivative. Biotransformation of carbazole yielded anthranilic acid as the major metabolite and was consistent with angular cis-dihydroxylation. Synthesis of a cis- diol epoxide derivative showed that the main cis-dihydrodiol metabolite of dibenzofuran has potential in the chemoenzymatic synthesis of natural products.

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.

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.

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).
