SYNTHESIS AND ANTIFUNGAL ACTIVITY OF BENZOXAZOLE DERIVATIVES WITH THEIR SAR ANALYSIS BY SAS-MAP

A simple and efficient method has been developed for the synthesis of benzoxazole derivatives. In the first step, 2-aminophenols reacted with various aldehydes in the presence of titanium supported nano-silica to produce an imine intermediate. Then the imine was oxidized to get the final azole compounds. Eleven derivatives were synthesized (c)-(m) via this simple and environmentally friendly procedure with high yields. The simple methodology (only 2 steps) with high yields for the reactions and easy procedure are the advantages of the newly developed method. The identification and characterization of all the synthesized compounds were confirmed by melting point, thin layer chromatography, FT-IR, H-1 NMR and C-13 NMR spectral data. Also elemental analysis was applied for five compounds. All the compounds were screened for antimicrobial activity by broth microdilution methods as recommended by CLSI. Of the tested compounds 2-(2,4-dichlorophenyl)-1,3-benzoxazole (g), and 2-( 4-chlorophenyl)-1,3-benzoxazole (f) inhibited the growth of all examined fungi, while 2-(4-nitrophenyl)-1,3-benzoxazole (c) exhibited inhibitory activities only against the tested yeasts.

Synthesis and antimicrobial evaluation of novel 5-substituted-2-(p-tert-butylphenyl)benzoxazoles

In the present study, a series of nine novel 5-substituted-2-(p-tert-butylphenyl)benzoxazole derivatives have been synthesized and their structures confirmed by spectral techniques and also tested for their antimicrobial activities. The minimum inhibitory concentrations (MIC) of the new benzoxazoles have been determined against standard bacterial and fungal strains and drug-resistant isolates and compared to those of several reference drugs. The new benzoxazole derivatives are found to possess a broad spectrum of antibacterial activity with MIC values of 8-256 mu g/mL. Especially, compound 9 is more active than standard drugs ciprofloxacin and cefotaxime against E. coli isolate with a MIC value of 8 mu g/mL. Also new compounds are less active than fluconazole with a MIC value of 256 mu g/mL against C. albicans and its isolate except for compound 9 that shows better activity other compounds with a MIC value of >4 mu g/mL for their antifungal activity.

Importance of Fluorine in Benzazole Compounds

Fluorine-containing heterocycles continue to receive considerable attention due to their unique properties. In medicinal chemistry, the incorporation of fluorine in small molecules imparts a significant enhancement their biological activities compared to non-fluorinated molecules. In this short review, we will highlight the importance of incorporating fluorine as a basic appendage in benzothiazole and benzimidazole skeletons. The chemistry and pharmacological activities of heterocycles containing fluorine during the past years are compiled and discussed.

The design, synthesis and evaluation of 2-aminobenzoxazole analogues as potent and orally efficacious ChemR23 inhibitors

We previously reported 2-aminobenzoxazole analogue 1 as a potent ChemR23 inhibitor. The compound showed inhibitory activity against chemerin-induced calcium signaling through ChemR23 internalization in CAL-1 cells, which are cell lines of plasmacytoid dendric cells (pDCs). Furthermore, compound 2 inhibited chemotaxis of CAL-1 triggered by chemerin in vitro. However, we noted a difference in the ChemR23 response to our inhibitor between rodents and non-rodents in a previous study. To address this issue, we performed optimization of ChemR23 inhibitors using CAL-1 cells endogenously expressing human ChemR23 and conducted a pharmacokinetics study in cynomolgus monkeys. Various substituents at the 4-position of the benzoxazole ring exhibited potent in vitro bioactivity, while those at the 6-position were not tolerated. Among substituents, a carboxyl group was identified as key for improving the oral bioavailability in cynomolgus monkeys. Compound 38a with the acidic part changed from a tetrazole group to a 1,2,4-oxadiazol-5-one group to improve bioactivity and pharmacokinetic parameters exhibited inhibitory activity against chemerin-induced chemotaxis in vitro. In addition, we confirmed the ChemR23 internalization of pDCs by compound 38a orally administered to cynomolgus monkeys. These 2-aminobenzoxazole-based ChemR23 inhibitors may be useful as novel immunotherapeutic agents capable of suppressing the migration of pDCs, which are known to be major producers of type I interferons in the lesion area of certain autoimmune diseases, such as systemic lupus erythematosus and psoriasis.

Cu(I) complexes regulated by N-heterocyclic ligands: Syntheses, structures, fluorescence and electrochemical properties

Three mononuclear Cu(I) complexes, namely, [Cu(2-PBO)(PPh3)(2)]center dot ClO4 center dot 2CH(2)Cl(2) (1), [Cu(3-PBO)(PPh3)(2)(ClO4)center dot CH2Cl2 (2) and [Cu(PBM)(PPh3)(2)]center dot ClO4 (3) (2-PBO = 2-(2′-Pyridyl)benzoxazole, 3-PBO = 2-(3′-Pyridyl)benzoxazole, PPh3 = 2-(2′-Pyridyl)benzimidazole, PPh3 = triphenylphosphine) have been synthesized and characterized by elemental analyses, IR, H-1 NMR, C-13 NMR, X-ray single crystal diffraction and thermal analysis. Photoluminescent investigation shows that complexes 1-3 exhibit distinct tunable light green (512 nm)-toyellow (557 nm) photoluminescence by varying the N-heterocyclic ligands. Three complexes show intense 2-PBO-based yellow, 3-PBO-based light green and intense PBM-based bright green luminescence upon irradiation with a standard UV lamp (lambda(ex) = 254 nm) at room temperature. Moreover, the electrochemical properties of 1-3 have been investigated by cyclic voltammetry. The results suggest the frontier molecular orbits and the HOMOLUMO energy gaps of these cuprous complexes are effectively adjusted through the introduction of different N heterocyclic ligands, thus achieving the selective luminescence of the cuprous complexes.

Azine based AIEgens with multi-stimuli response towards picric acid

Multifunctional aggregation induced emission luminogens (AIEgens) are novel materials which have significant applications in various fields including biomedical, optoelectronics and sensors. Enormous efforts have been directed towards the strategic development and characterisation of AIEgens, in order to better understand the AIE mechanism. Herein, we studied the photophysical properties of symmetrical azine (D-pi-D) based AIEgens in detail by varying the solvent polarity and viscosity. The AIE behaviour of the azine derivatives relies on the substituents on the nitrogen atom of the amine moiety. Further, these azine derivatives sense the picric acid (PA) with high selectivity and sensitivity in both monomer and aggregated forms. The hydrogen bonding interaction of PA with any one side of the amine nitrogen leads to the formation of a new intramolecular charge transfer state which results in the formation of new absorption and emission spectra. Interestingly in the presence of PA, azine monomers exhibit fluorescence enhancement in pure THF, while aggregated azine molecules show fluorescence quenching in THF-water mixtures.

(Phosphinito)aryl benzimidazole PCN pincer palladium(II) complexes: Synthesis, characterization and catalytic activity in C-H arylation of azoles with aryl iodides

The PCN pincer Pd(II) complexes 4a-c with (phosphinito)aryl benzimidazole ligands were conveniently synthesized by one-pot phosphorylation/palladation reaction of a (2-benzimidazolyl)-containing m-phenol derivative 3. The three complexes were well characterized by spectroscopic methods, elemental analysis and their molecular structures were further determined by X-ray single-crystal diffraction. The Pd(II) center in each complex adopts a typical distorted-square-planar geometry. With a catalyst loading of 0.25-0.5 mol%, complex 4a could effectively catalyze C-H arylation of benzothiazole, benzoxazole and thiazole with various aryl iodides in the presence of Cul as a cocatalyst.

Light-Induced Bending of Needle-Like Crystals of Naphthylvinylbenzoxazole Triggered by trans-cis Isomerization

New diarylethene derivatives containing benzoxazole (NBO) and benzothiazole (NBT) have been synthesized. Light-induced trans-cis isomerization of NBO and NBT took place in crystals, and only induced the needle-like crystals of NBO to bend backwards away from the UV light source. The movement of the atoms was deemed to take place during the isomerization of NBO; hence, strain would be produced and accumulated rapidly in the surface of crystals exposed to UV light. The uniform release of strain led to the bending of needle-like crystals. The light-induced trans-cis isomerization efficiency of NBT was too low to drive the motion of crystals, which might have originated from the large repulsion between naphthyl and benzothiazole. These results provide a new platform for the transformation of light energy into mechanical energy in molecular crystals through the unimolecular photochemical reaction of diarylethene derivatives.
