Benzoxazole Derivatives as Promising Antitubercular Agents

Tuberculosis (TB) is an infectious disease caused predominantly by bacillus Mycobacterium tuberculosis (MTB). The increasing prevalence of multidrug-resistant MTB necessitates the discovery and development of alternative drugs against tuberculosis with a new mechanism of action. Over the past years, several benzoxazole derivatives have been synthesized and screened for their biological activity. Interestingly, some of them had promising antitubercular activity. Despite that, none of the benzoxazole derivatives has entered the phase of the preclinical hit-to-lead optimization step in anti-TB research. In this review, we are summarizing recently published articles that evaluate the potency of benzoxazole heterocycle in the development of novel anti-TB agents and outlined the future aspects of this promising heterocycle.

Synthesis and properties of poly(benzoxazole imide)s derived from two isomeric diamines containing a benzoxazole moiety

Two isomeric diamine monomers, 2-(3-aminophenyl)benzo[d]oxazol-5-amine (2a) and 2-(3-aminophenyl)benzo[d]oxazol-6-amine (2b), were designed and synthesized. The corresponding novel series of poly(benzoxazole imide)s (PBOPIs) were prepared with commercial tetracarboxylic dianhydrides via thermal imidization. These series of PBOPIs showed great T(g)s ranging from 285 to 363 degrees C, excellent thermal stability when performed at 5% weight loss temperatures (T(d5%)s) of 510-564 degrees C in N-2 and good mechanical properties (tensile strengths of 103-126 MPa, tensile moduli of 2.9-3.7 GPa and elongations at break of 3.0-6.5%). Furthermore, controlled molecular weight (M-w) polymers PI-3a-PA and PI-3b-PA derived from 4,4 ‘-oxydiphthalic anhydride (ODPA) with 2a and 2b demonstrated good melt processability with minimum complex viscosities of 2258 and 3444 Pa center dot s at 420 degrees C and low melt viscosity ratios of 1.29 and 1.93 at 400 degrees C, respectively. The PI-b series showed higher T-g & T-d5% and lower transparency compared with the PI-a series due to the isomeric effect.

Synthesis and characterization of amino glucose-functionalized silica-coated NiFe2O4 nanoparticles: A heterogeneous, new and magnetically separable catalyst for the solvent-free synthesis of 2,4,5-trisubstituted imidazoles, benzo[d]imidazoles, benzo[d]oxazoles and azo-linked benzo[d]oxazoles

Amino glucose-functionalized silica-coated NiFe2O4 nanoparticles (NiFe2O4@SiO2@amino glucose) were chemically synthesized and characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), energy dispersive X-ray analysis (EDX), vibrating sample magnetometer (VSM), Zetasizer and Fourier transform infrared spectroscopy (FT-IR) instruments. NiFe2O4@SiO2@amino glucose supply an environmentally friendly procedure for the synthesis of 2,4,5-trisubstituted imidazoles through one-pot multicomponent condensation of benzil or benzoin, ammonium acetate with aryl aldehydes and for the synthesis of benzoxazoles using condensation reaction of 2-aminophenol with aryl aldehydes under solvent free condition. In the other study, this synthesized magnetically reusable catalyst was introduced as a new avenue for the synthesis of benzofdlimidazoles using the reaction between aryl aldehydes and 1,2-diaminobenzene. These compounds were obtained in high yields and short reaction times. The catalyst could be easily recovered and reused for five cycles with almost consistent activity. Synthesized compounds were characterized by their physical constant, comparison with authentic samples, FT-IR, H-1 NMR, C-13 NMR spectroscopy and elemental analysis. (C) 2018 Elsevier B.V.

One-Pot Synthesis of 3-Difluoromethyl Benzoxazole-2-thiones

A one-pot strategy for the diversified synthesis of 3-difluoromethyl benzoxazole-2-thiones is reported. The reaction of 2-aminophenol, sodium chlorodifluoroacetate, and elemental sulfur in the presence of NaOt-Bu gives exclusively 3-difluoromethyl benzoxazole-2-thiones in good yield (up to 98%). The mechanism of this reaction presumably involves first cyclization of 2-aminophenols with thiocarbonyl fluoride, followed by N-difluoromethylation with difluorocarbene. The developed synthetic procedures are versatile, robust, and easily scalable for the synthesis of 3-difluoromethyl benzoxazole-2-thione derivatives, some of which have shown insecticidal activities.

Diarylethene-based xerogels: the fabrication of more entangled networks driven by isomerization and acidofluorochromism

Fully-conjugated styrylbenzoxazoles and styrylbenzothiazoles of BOAF24, BOACl24, BOACl35, BOABr24, BOABr35, BTAF24, BTACl24 and BTABr24 without traditional gelation groups could form organogels. It was found that introduction of chlorine atoms in the 2,4-positions of the phenyl group would improve gelation abilities, and benzothiazole derivatives exhibited better gelation abilities than benzoxazoles with a similar -skeleton due to better -electron delocalization. Interestingly, the organogel of BTACl24 could change into solution by UV light due to trans-cis isomerization, which could also induce morphological changes in xerogels. The smooth organogel nanofibers stretched out lots of thin arms’ to hold together or to catch other nanofibers upon UV irradiation, so more entangled networks were generated. Moreover, TFA (trifluoroacetic acid) could induce a gel-sol transformation on account of the protonation of the benzoxazole or benzothiazole unit, accompanied by emission quenching. BTACl24 exhibited higher performance than BOACl24 in the detection of TFA because of its strong basicity. The decay time and the detection limit of BTACl24 in xerogel-based film towards TFA vapor were of 0.7 s and 0.3 ppm, respectively. Therefore, organogelation of non-traditional organogelators is a powerful approach to the fabrication of multi-stimuli-responsive soft materials, and provides a new method to generate more entangled 3D networks through photochemical reactions in xerogels.

Synthesis and application of benzoxazole derivative-based fluorescent probes for naked eye recognition

A fluorescent probe to detect biothiols (GSH/Hcy/Cys) was synthesized with benzothiazole as the fluorophore and nitromethane as the recognition group. The recognition mechanism of the fluorescent probe was deduced. It was found that a nitroalkene in the molecule was used as the recognition site for this probe and reacted with the mercapto group of the biothiols by electrophilic addition, significantly enhancing the fluorescent signal. Experimental results showed that the fluorescent probe had a low detection limit, good selectivity, strong anti-interference ability, and good naked eye recognition. The probe could detect biothiols (GSH/Hcy/Cys) in 20% organic solvent, with detection limits of 0.33 mu M, 0.70 mu M, and 0.87 mu M, respectively. The probe will be applied further in biosensors and other fields.

Novel Pyrazolyl Benzoxazole Conjugates: Design, Synthesis, Molecular Docking Studies and in vitro Anticancer Activities

Nowadays, hybrid drugs have gained a significant role in the treatment of different health problems. Most of the hybrid molecules with different heterocyclic moieties were proved to be potent anti-tumor agents in cancer chemotherapy. Hence, the present study is aimed at the evaluation of in vitro anticancer activity of novel hybrid molecules (pyrazolyl benzoxazole conjugates) and to investigate their anticancer activity by molecular docking studies. Designed, synthesized and characterized the novel pyrazolyl benzoxazole conjugates. Anticancer activity of these compounds was determined by SRB assay. Then molecular docking studies were carried out against proto-oncogene tyrosine-protein kinase (ATP-Src, PDB: 2BDF), a putative target for cancer. All the synthesized compound derivatives were evaluated against MCF-7, KB, Hop62 and A549 cancer cell lines. Compounds 9b and 9c exhibited excellent anticancer activities with GI(50) values of <0.1 mu M against MCF-7 and A549 cell lines. Compound 9e exhibited good antitumor activity on MCF-7 and A-549 with GI(50) values of 0.12 mu M and 0.19 mu M respectively. Compound 9g showed better anticancer activity on A-549 cancer cell line with GI(50) of 0.34 mu M. The two-hybrid molecules 9b and 9c are found to be comparably potent with the standard drug doxorubicin and may act as drug lead compounds in medicinal chemistry aspect. The present docking investigation proved that having benzoxazole of compound 9c at the position of benzofuran of reference compound (N-acetyl pyrazoline derivative) might be valid for contributing to anti-cancer activity. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 352-34-1.

Structural study of mono-, di- and tetranuclear complexes of the {Re(CO)(3)}(+) fragment with thiosemicarbazone/thiosemicarbazonate ligands containing benzothiazole or benzoxazole groups

Nine thiosemicarbazone ligands (H2Ln, n = 1-9) containing benzothiazole or benzoxazole groups at the C(2) atom of the thiosemicarbazone have been prepared and characterized. A crystal structure study was performed on six of these free ligands and the role of the pi-pi interactions in the molecular association was analyzed. The coordination behavior of the thiosemicarbazones towards the {Re(CO)(3)}(+) fragment was investigated and three types of complexes were obtained: mononuclear fac-[ReX(H(2)Ln)(CO)(3)], X = Cl or Br, with bidentate ligands, dinuclear [Re-2(HLn)(2)(CO)(6)] with monodeprotonated bridging thiosemicarbazonates yielding Re2S2 cores and tetranuclear [Re-4(L-2)(2)(CO)(12)(EtOH)(2)] with an unusual bideprotonated thiosemicarbazonate ligand. The intermolecular interactions before and after metal coordination were analyzed. In the dinuclear complexes, two different approximate symmetries were observed depending on the relative orientation of the thiosemicarbazonate ligands with respect to the Re2S2 diamond. The intramolecular interactions in the dimers and their relationship with the two possible symmetric dispositions were analyzed. The findings, in conjunction with theoretical calculations, allowed the main stabilizing factors for each type of symmetry to be elucidated.

Heteroatom controlled probe-water cluster formation of a series of ESIPT probes: An exploration with fluorescence anisotropy

The present letter reports unusual high fluorescence anisotropy of excited state intramolecular proton transfer (ESIPT) prone 2-(2′-hydroxyphenyl) benzoxazole (HBO) in water followed by its imidazole (HBI) and thiazole (HBT) analogues. The low fluorescence anisotropy of the acetate compound of HBO in water reveals the key role of the hydrogen bonded cage-like probe-water cluster for the findings in water. Formation of the aquated cluster is controlled possibly by the combined effect of the electronegativity and mesomeric effect of the heteroatom away from the ESIPT site. The work invites further explorations, preferably from computational perspective, for a proper explanation.

Application of 352-34-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 352-34-1 is helpful to your research.
