Two D-pi-A-A sensitizers (AZ6-B20 and AZ6-B21) were synthesized by inserting the benzoxazole group as an auxiliary acceptor between the pi-linker and the acceptor. And a D-A-pi-A sensitizer (AZ6-B19) was also synthesized in our previous works by the insertion of the benzoxazole between the donor and the pi-linker. The effects of benzoxazole groups on the properties at different sites of dye sensitizers were distinguishing. Their light harvest abilities were investigated by UV-vis spectra both in the solution and on the films. The results show that the absorption bands of UV-vis spectra are quite different from D-A-pi-A and D-pi-A-A dyes. The much more intensive molar extinction coefficients (53807 M-1 cm(-1) and 52555 M-1 cm(-1)) were observed at around 575 nm for D-pi-A-A dyes. The photovoltaic properties of DSSCs were also evaluated by J-V curves and IPCE measurements. The results confirmed that D-pi-A-A dyes delivered high photovoltaic efficiency (AZ6-B20: 7.48%, AZ6-B21: 8.67%) compared with that of D-A-pi-A dye (AZ6-B19: 3.27%). The details on the relation of the structures/ properties were discussed by the optical physical absorption, electrical chemical measurements and DFT calculations.

A facile, efficient, and eco-friendly strategy to access benzoxazole heterocyclic products has been accomplished through oxidation of catechols followed by condensation/cyclization/aromatization sequences. This process is catalyzed by nanostructured iron(III)-porphyrin complex to form desired benzoxazole derivatives at room temperature under air condition. The procedure is widely applicable to diverse amines, and can provide the heterocyclic products in a scalable fashion, as well. One of the most significant types of oxidizing agents in nature is the iron-porphyrin complexes (0.1 mol-%), existing in the structure of hemoglobin. They have benefits such as low toxicity and high oxidation potential for many substrates.

Benzoxazoles and their derivatives have exerted anti-cancer and anti-inflammatory (immunomodulatory) potential due to their anti-proliferative effect on the cells. These molecules are DNA basebioisosteres, therefore, their mechanism of action could be by mimicking the structures of the DNA bases and halting the DNA polymerization processes. Based on their anti-proliferative effect, in our study we aimed to decipher the potential anti-inflammatory activities of unique bisbenzoxazole derivatives in vitro on mammalian macrophages. Being able to manipulate the inflammatory function of macrophages would enable the regulation of the immune response against danger stimuli. This would enable us better prognosis against different types of the diseases ranging from autoimmune disorders to cancer. Our results support the stark anti-inflammatory potential of bisbenzoxazole derivatives RHE 241 and RHE 248 in vitro on the LPS activated mammalian macrophages. After further delineation of their mechanism of action in vitro and their in vivo potency, these molecules could be utilized as potent anti-inflammatory medicines.

Inflammatory responses are generated against the danger molecules under normal conditions but excessive or chronic inflammation leads to tissue degeneration and loss of function. To prevent the disease symptoms associated with the inflammatory disorders or the growth of tumor types that require inflammatory environment, generation of immunomodulatory drugs with suppressive functions have great potentials. In this study, we synthesized new generation of anti-proliferative bis-benzoxazole derivatives and tested their anti-inflammatory and anti-cancer potencies. For this purpose, we used a well-characterized mouse macrophage cell line (RAW 264.7). Furthermore, anti-cancer activity of these compounds were tested using MTT assay on prostate (DU145) and breast (MCF7) cancer cells. The screening results revealed that all compounds possessed a high-level anti-inflammatory potential by reducing the expression of inflammatory cytokines in LPS-stimulated macrophages. There were significant and substantial reductions in the secreted TNF alpha, IL6, and IL1 beta levels by chemically treated LPS-induced macrophages compared to non-treated induced ones. Our compounds exerted their anti-inflammatory effect in a dose-dependent manner and they were biologically active even in low nanomolar range concentrations. Bis-benzoxazole derivatives had anti-proliferative effect on MCF-7 and DU-145 cancer cells. Together, our results present a series of new bis-benzoxazole-based compounds with potential therapeutic effects in inflammatory diseases and on tumor cells.

Novel series of benzoxazoles 4(a-f)-16 were designed, synthesized, and evaluated for anticancer activity against HepG2, HCT-116, and MCF-7 cells. HCT-116 was the most sensitive cell line to the influence of the new derivatives. In particular, compound 5(e) was found to be the most potent against HepG2, HCT-116, and MCF-7 with IC50 = 4.13 +/- 0.2, 6.93 +/- 0.3, and 8.67 +/- 0.5 mu M, respectively. Compounds 5(c), 5(f), 6(b), 5(d), and 6(c) showed the highest anticancer activities against HepG2 cells with IC50 of 5.93 +/- 0.2, 6.58 +/- 0.4, 8.10 +/- 0.7, 8.75 +/- 0.7, and 9.95 +/- 0.9 mu M, respectively; HCT-116 cells with IC50 of 7.14 +/- 0.4, 9.10 +/- 0.8, 7.91 +/- 0.6, 9.52 +/- 0.5, and 12.48 +/- 1.1 mu M, respectively; and MCF-7 cells with IC50 of 8.93 +/- 0.6, 10.11 +/- 0.9, 12.31 +/- 1.0, 9.95 +/- 0.8, and 15.70 +/- 1.4 mu M, respectively, compared with sorafenib as a reference drug with IC50 of 9.18 +/- 0.6, 5.47 +/- 0.3, and 7.26 +/- 0.3 mu M, respectively. The most active compounds 5(c-f) and 6(b,c) were further evaluated for their vascular endothelial growth factor receptor-2 (VEGFR-2) inhibition. Compounds 5(e) and 5(c) potently inhibited VEGFR-2 at lower IC50 values of 0.07 +/- 0.01 and 0.08 +/- 0.01 mu M, respectively, compared with sorafenib (IC50 = 0.1 +/- 0.02 mu M). Compound 5(f) potently inhibited VEGFR-2 at low IC50 value (0.10 +/- 0.02 mu M) equipotent to sorafenib. Our design was based on the essential pharmacophoric features of the VEGFR-2 inhibitor sorafenib. Molecular docking was performed for all compounds to assess their binding pattern and affinity toward the VEGFR-2 active site.

Alzheimer’s disease (AD) is associated with multifactorial neuropathological conditions, which include cholinergic deficit, amyloid-beta plaques formation, loss of neuronal plasticity and neuronal death. Treating such multifactorial conditions with a single target directed approach is considered to be inadequate. Accordingly, multi-target directed ligand (MTDL) strategy has been evolved as an auspicious approach for the treatment of AD. In light of that, a library of 2-substituted benzo[d]oxazol-5-amine derivatives (29-39; 86-107) was designed using the scaffold hopping guided MTDLs strategy, synthesized and evaluated through various in-vitro and in-vivo biological studies. The optimal compound 92 exhibited potent inhibitory activities against AChE (IC50 = 0.052 +/- 0.010 mu M), BuChE (IC50 = 1.085 +/- 0.035 mu M), and significant amyloid-beta aggregation (20 mu M) inhibition. The compound possessed better blood-brain barrier permeability (Pe = 10.80 +/- 0.055 x 10(-6) cm s(-1)) in PAMPA assay and neuro protective properties (40 mu M) on SH-SY5Y neuroblastoma cell lines. Furthermore, in-vivo behavioural studies were performed on Y-maze test (scopolamine-induced amnesia model) and Morris water maze test (A beta(1-42) induced ICV rat model). The compound 92, at a dose of 10 mg/kg oral administration, demonstrated a substantial improvement of the cognitive and special memory impairment. In summary, both in-vitro and in-vivo investigations evidenced that compound 92 was a potential lead for the discovery of safe and effective disease-modifying agents for AD.

A series of benzoxazole derivatives and some possible primary metabolites were evaluated as anticancer agents. In vitro anti-proliferative activities of the compounds were tested using the SRB assay on cancerous (HeLa) and non-cancerous (L929) cell lines. It was found that 17 of 21 tested compounds had cytotoxic activity on HeLa cells and the cytotoxic activities of the compounds were 15-700 times higher than on L929 cells. We generated two distinct pharmacophore models for the cytotoxic activities of the compounds on HeLa and L929 cells. While active compounds such as camptothecin and X8 fitted the two models generated for both cell lines, selective cytotoxic compounds such as XT3B fitted only the model generated for HeLa cells. Evaluation of the genotoxic activities of the cytotoxic compounds with the alkaline comet assay revealed that compounds X17 and XT3 showed strong genotoxic effects against HeLa cells at low concentrations whereas they had no genotoxic effect on L929 cells. Due to the selective ability for inducing DNA strand breaks only on cancerous cells, the compounds were identified as effective derivatives for anticancer candidates.
