We describe the preparation and characterization of two zinc hybrid luminescent structures based on the flexible and emissive linker molecule, trans-(4-R,4′-R′) stilbene, where R and R′ are mono- or poly-coordinating groups, which retain their luminescence within these solid materials. For example, reaction of trans-4,4′-stilbenedicarboxylic acid and zinc nitrate in the solvent dimethylformamide (DMF) yielded a dense 2-D network featuring zinc in both octahedral and tetrahedral coordination environments connected by trans-stilbene links. Similar reaction in diethylformamide (DEF) at higher temperatures resulted in a porous, 3-D framework structure consisting of two interpenetrating cubic lattices, each featuring basic to zinc carboxylate vertices joined by trans-stilbene, analogous to the isoreticular MOF (IRMOF) series. We demonstrate that the optical properties of both embodiments correlate directly with the local ligand environments observed in the crystal structures. We further demonstrate that these materials produce high luminescent response to proton radiation and high radiation tolerance relative to prior scintillators. These features can be used to create sophisticated scintillating detection sensors.

The present invention relates to topical pharmaceutical emulsion compositions comprising a therapeutically effective amount of 3,5-Dihydroxy-4-isopropyl-trans-stilbene or a pharmaceutically acceptable salt thereof, an oil phase, a water phase, a surfactant, and an antioxidant, and wherein the emulsion composition is homogeneous and / or the active is solubilized in the oil phase. The invention also relates to methods of treating a dermatological condition or disorder in a patient by administering the present compositions to the skin of the patient.

A molecular probe for labeling myelin includes a fluorescent trans-stilbene derivative.

The present invention relates to a novel method of treatment of acne in a human patient in need thereof, comprising administering topically to said patient an effective amount of the compound 3,5-Dihydroxy-4-isopropyl-trans-stilbene (Compound 1) or a pharmaceutically acceptable salt thereof.

The present invention relates to method(s) of treating a subject afflicted with cancer or a precancerous condition, an inflammatory disease or condition, and / or stroke or other ischemic disease or condition, the method comprising administering to the subject or patient in need a composition comprising a therapeutically effective amount of a substituted cis or trans-stilbene.

A copolyester composition comprising units of residues of a) about 1-40 mole % of trans 3,3′, trans 4,4′ stilbene dicarboxylic acid and the combination thereof, b) about 99-60 mole % of cis,trans, and the combination thereof of 1,4 cyclohexane dicarboxylic acid, and c) about 50-100 mole % of cis, trans, and the combination thereof of 1,4-cyclohexane dimethanol. The resulting copolyester may be characterized by its clarity, as well as enhanced heat performance due to the presence of the stilbene moiety.

The present invention relates to stilbene and quinine compounds related to combretastatin A-4 and their use as anticancer compounds and prodrugs. The compounds include those with an alkyl group on the double bond of cis or trans-stilbenes, compounds with one or more (and preferably 2 or 3) alkyl group substituents on the stilbene a ring, compounds with an alkoxy group other than methoxy at position 3, 4 and / or 5 of the stilbene A ring, compounds (or prodrugs) in which BOC amino acid esters are formed with the phenolic hydroxyl at the 3-position of the B ring and compounds (or prodrugs) based on a benzoquinone B ring. The present invention further relates to the photochemical reactions of stilbene compounds, either the above compounds disclosed for the first time herein or compounds based on prior art stilbenes. These reactions include the photochemical release of an active form of the compound from a prodrug conjugate and the photochemical isomerisation of the compounds, especially from a trans to cis form of compounds. The reactions can be used alone or in combination to convert inactive or comparatively less active forms of the compounds to more active forms, thereby allowing the compounds to be selectively targeted, e.g., activating them at the site of a tumour.

The invention belongs to the technical field of metal-organic framework materials, and in particular relates to the preparation of a zirconium-based metal-organic framework material and its application to the detection and adsorption of nitrofuran antibiotics in water. The present invention is based on trans-4,4'-stilbene dicarboxylic acid and zirconium chloride to synthesize a dual-functional UiO series metal-organic framework—Zr-fcu-sti, which simultaneously detects and adsorbs antibiotics, and can achieve low detection limits. Highly selective fluorescence detection and rapid, high-capacity adsorption removal of nitrofuran antibiotics from water.
