Fibrous nanoaggregates of a new benzoxazole-based derivative have been reported. This derivative exhibits not only H-aggregates but also strong yellow fluorescence, which is different from the traditional understanding of H-aggregates.

The endeavor of this study was to design, synthesize and investigate the in vivo anti-inflammatory and analgesic activity of some novel 2-(2-(benzo[d]oxazol-2-yl) phenylamino)-N-(substituted phenyl) acetamide (2A-2F) derivatives. 2-(2-aminophenyl) benzoxazole (D1) was synthesized by the condensation of anthranilic acid with starting material 2-aminophenol in the existence of poly phosphoric aci...

A bis(benzoxazole) derivative with metal-chelating ligand (DPA), Zinhbo-1, exhibits a large fluorescence turn-on effect (up to 10-fold) upon zinc-binding. The metal chelation enables excited state intramolecular proton transfer (ESIPT), giving an additional emission band in the near-IR region (approximately 710 nm) with a large Stokes shift (ca. 230 nm).

In the title compound, C(14)H(11)ClN(2)O(2), the 2,3-dihydro-1,3-benzoxazole ring system is essentially planar [maximum deviation = 0.009 (2) Å] and makes a dihedral angle of 79.15 (7)° with the phenyl ring. Inter-molecular N-H⋯O and weak C-H⋯Cl hydrogen bonds occur in the crystal structure.

In the title mol-ecule, C(13)H(10)N(2)O, the dihedral angle between the benzoxazole ring system and the benzene ring is 11.8 (1)°. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds and π⋯π inter-actions [centroid-centroid distance = 3.6560 (15) Å] to form a two-dimensional network.

The title compound, C(30)H(16)N(4)O(4), reveals [Formula: see text] crystallographic and mol-ecular symmetry and accordingly the asymmetric unit comprises one half-mol-ecule. The dihedral angle between the planes of the two geminal benzoxazole rings is 74.39 (5)°. The packing features weak C-H⋯N and π-π inter-actions [centroid-centroid distance = 3.652 (1) Å].

Benzoxazole nucleus is one of the most important heterocyclic compounds exhibiting remarkable pharmacological activities. The present review provides a broad overview of the synthesis and pharmacological activities such as antimycobacterial, anticonvulsant, anti-inflammatory, anticancer, DNA topoisomerase inhibitor, cholesterol ester transfer protein inhibitor and miscellaneous activities.

High power density lithium ion battery (HLIB) separators were fabricated for the first time from thermally rearranged poly(benzoxazole-co-imide) (TR-PBOI) nanofibrous membranes coated with TR-PBOI nanoparticles, which show distinct thermal and dimensional stabilities as well as excellent cycle retention and rate capability.

Nucleosides spin-labelled with isoindoline-derived benzimidazole ((Im)U) and benzoxazole ((Ox)U) moieties were synthesized and incorporated into DNA oligonucleotides. Both labels display limited mobility in duplex DNA but (Im)U was less mobile, which was attributed to an intramolecular hydrogen bond between the N-H of the imidazole and O4 of the uracil nucleobase.
