In this paper, new liquid crystal compounds with negative dielectric anisotropy were synthesised by regulating the substituents on the benzofuran ring. Their structures were confirmed by(1)H-nuclear magnetic resonance,(CNMR)-C-13 and mass spectra. The effects of substituent on the properties of liquid crystals were investigated. Compared with the reference compounds, the compounds with 5-ethoxy-6,7-difluorobenzofuran ring exhibit higher clearing points as well as the tendency of expansion of SmA phase range. The density functional theory calculation results reveal that the 6-ethoxy-7-fluorobenzofuran-based compound has smaller aspect ratio than that of the 5-ethoxy-6,7-difluorobenzofuran-based compound, which results in the diminish of the mesophase. Although the dielectric anisotropy of the 5-ethoxy-6,7-difluorobenzofuran-based compound is slightly lower than that of the reference compound, it has both the largest perpendicular and parallel dielectric constant.

Mutations in RAS/RAF occur in large portion of malignancies and are associated with aggressive clinical behaviors and poor prognosis. Therefore, we developed a novel benzoxazole compound (KZ-001) as a highly potent and selective MEK 1/2 inhibitor. Our efforts were focused on enhancing the activity of the known MEK inhibitor AZD6244 and overcoming the shortcomings existing in current MEK inhibitors. Here we show that compound KZ-001 exhibits approximately 30-fold greater inhibition against BRAF- and KRAS-mutant tumor cells than that of AZD6244. These results were also demonstrated using in vivo xenograft models. Furthermore, pharmacokinetics (PK) analysis was performed for KZ-001, and this compound showed good orally bioavailability (28%) and exposure (AUC(0-infinity) = 337 +/- 169 ng h/mL). To determine its potential clinical application, the synergistic effect of KZ-001 with other agents was investigated both in vitro and in vivo (xenograft models). KZ-001 exhibited synergistic anti-cancer effect in combination with BRAF inhibitor vemurafenib and a microtubule-stabilizing chemotherapeutic agent docetaxel. In addition, KZ-001 inhibited the MAPK pathway like known MEK inhibitors. In summary, KZ-001, a structurally novel benzoxazole compound, was developed as a MEK inhibitor that has potential for cancer treatment.

A novel series of benzoxazolyl linked benzylidene based rhodanine and their cyclic analogs were synthesized, characterized and evaluated for their alpha-amyloglucosidase inhibitory activity. Out of eight target compounds, two compounds (4b and 5b) displayed potent inhibitory activity against alpha-amyloglucosidase with IC50 values in the range of 0.24 +/- 0.01-0.94 +/- 0.01 A mu M as compared to standard drug acarbose. Among all the tested compounds, compound 5b containing rhodanine at 3-position of phenyl was found to be the most active inhibitor of alpha-amyloglucosidase. Docking studies showed the existence of potential H-bonding interactions between synthesized compounds and alpha-glucosidase which might be responsible for good biological activity.

New difluoroboron beta-ketoiminate boron complexes bearing benzoxazole (CBO) and benzothiazole (CBS) have been synthesized. It was found that CBO was almost non-emissive in THF, and the emission could be intensified significantly when great amount of H2O was added, illustrating AIE (aggregation-induced emission) property. CBS could not show AIE property in THF/H2O system, but its emission in solid state was also strong. The single crystal structure of CBS suggested that pi-pi interactions and the hydrogen bonds of C(Ar) – F center dot center dot center dot H, C(Ar) – H center dot center dot center dot S and C(Ar) – H center dot center dot center dot Cl would suppress the rotation of single bonds, resulting into obvious emission enhancement. It is interesting that the as-synthesized crystals of CBO and CBS both emitted azure light, and the grinding made their emitting colors to change into cyan and green, which could be recovered under fuming with DCM or heating. The reversible mechanofluorochromism was due to the transformation between crystalline and amorphous states, which could be confirmed from the results of absorption spectra, XRD patterns and DSC curves in different solid states. Additionally, the high-contrast mechanofluorochromism of CBS compared with CBO might be originated from the loose packing in crystalline state and the better pi-electron delocalization.

Folates are essential biomolecules required to carry out many crucial processes in leishmania parasite. Dihydrofolate reductase-thymidylate synthase (DHFR-TS) and pteridine reductase 1 (PTR1) involved in folate biosynthesis in leishmania have been established as suitable targets for development of chemotherapy against leishmaniasis. In the present study, various computational tools such as homology modelling, pharmacophore modelling, docking, molecular dynamics and molecular mechanics have been employed to design dual DHFR-TS and PTR1 inhibitors. Two designed molecules, i.e. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were synthesized. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay was performed to evaluate in vitro activity of molecules against promastigote form of Leishmania donovani using Miltefosine as standard. 2-(4-((4-nitrobenzyl)oxy)phenyl)-1H-benzo[d]imidazole and 2-(4-((2,4-dichlorobenzyl)oxy)phenyl)-1H-benzo[d]oxazolemolecules were found to be moderately active with showed IC50 = 68 +/- 2.8 mu M and 57 +/- 4.2 mu M, respectively.

Based on benzoxazole and benzothiazole scaffold as an important pharmacophore, two series of 2-(aryloxymethyl) benzoxazole and benzothiazole derivatives were synthesized and their antifungal effects against eight phytopathogenic fungi were evaluated. Compounds 5a, 5b, 5h, and 5i exhibited significant antifungal activities against most of the pathogens tested. Especially 5a, 5b, 5h, 5i, 5j, and 6h inhibited the growth of F. solani with IC50 of 4.34-17.61 mu g/mL, which were stronger than that of the positive control, hymexazol (IC50 of 38.92 mu g/mL). 5h was the most potent inhibitor (IC50 of 4.34 mu/mL) against F. Solani, which was about nine times more potent than hymexazol. Most of the test compounds displayed significant antifungal effects against B. cinerea (IC50 of 19.92-77.41 mu g/mL), among them, 5a was the best one (IC50 of 19.92 mu g/mL). The structure-activity relationships (SARs) were compared and analyzed. The result indicates that the electron-drawing ability and position of the substituents have a significant impact on biological activities. Furthermore, docking studies were carried out on the lipid transfer protein sec14p from S. cerevisiae, and preliminarily verified the antifungal activities. Taken together, these results provide 2-(phenoxymethyl)benzo[d]oxazole as an encouraging framework that could lead to the development of potent novel antifungal agents.

We provide a critical perspective of the burgeoning literature on microporous polymers prepared using thermal rearrangement (TR) processes based on the learning derived from analogous chemistry involving small-molecular-weight compounds. TR polymers have shown interesting permeability-selectivity relationships in gas separation and, thus, have generated wide interest as potential membrane materials for industrial applications. The intractable nature of the products obtained by TR processes has precluded rigorous structural elucidation of the polymers. Based on small-molecule chemistry, we conclude that structures are likely to be more complex than generally depicted in the published literature. Interestingly, a simpler chemistry, namely thermal dehydrocyclization (TCD), leads to products identical to those derived from TR, but at significantly lower temperatures. However, TCD chemistry does not involve a skeletal rearrangement of the kind purported in TR during the conversion of imide to oxazole ring resulting in spatially confined heterocyclic ring polymers. Yet, they show similar fractional free-volume elements as exhibited by TR polymers. This is intriguing and points to a need for more careful examination of the factors responsible for microporosity in such materials. TR chemistry as currently practiced appears limited to only benzoxazole-type structures. The ability to precisely control and reproducibly produce materials with well-defined structure and properties will be a key to large-scale manufacture and industrial applications of such materials. Seen from this perspective, TR processes leave much to be desired and further improvements are clearly warranted. (c) 2019 Society of Chemical Industry
