摘要:
A process is provided for carrying out an oxidation on a sprayable feed including a furanic substrate to be oxidized and a catalytically effective combination of cobalt, manganese, and bromide components for catalyzing the oxidation of the furanic substrate, which process comprises spraying the feed into a reactor vessel as a mist, supplying an oxidant, reacting the furanic substrate and the oxidant, and managing the exothermic temperature rise due to the reaction through a selection and control of the operating pressure within the reactor vessel. A crude dehydration product from the dehydration of fructose, glucose or both, including 5-hydroxymethylfurfural, can be directly oxidized by the process to produce 2,5-furandicarboxylic acid in surprisingly increased yields.

摘要:
Compositions comprising a tripeptide having the sequence XC1C2; wherein X is any amino acid such that XC1C2 is capable of binding a metal in a square planar orientation or square pyramidal orientation or both; and wherein C1 and C2 are the same or different; and wherein C1 and C2 individually are chosen from a cysteine and a cysteine-like nonnatural amino acid, as well as metal-XC1C2 complexes and methods for forming such complexes.
摘要:
A method of inhibiting formation of cancerous metabolites, of inhibiting cytochrome P450 2A13 from forming carcinogen metabolites, and/or inhibiting formation of cancerous lung cells in a subject can include: providing a morpholine compound that selectively interacts with cytochrome P450 2A13 over cytochrome P450 2A6; administering a therapeutically effective amount of the morpholine compound or derivative to the subject. The morpholine compound or derivative can be substantially more selective for interacting with the cytochrome P450 2A13 over the cytochrome P450 2A6. The morpholine compound or derivative can also be substantially non-interactive with other physiological components. The morpholine compound or derivative can include a structure that selectively interacts with cytochrome P450 2A13 over cytochrome P450 2A6, such as Compounds 1-34 of Formulas A-D.
摘要:
Gold nanoparticles having luminol covalently linked thereto and optionally functionalized with an oligonucleotide and bacterial or viral detection assays. In one aspect, the detection system for detecting an analyte in a sample comprises a light-shielding container having a fiberoptic cable for transmitting light generated within the light-shielding container to a photodetector; a plurality of functionalized nanoparticles deposited in solid form on or within a support, such that the support is located within the light-shielding container; wherein the functionalized nanoparticles comprise nanoparticles covalently attached to one or more chemiluminescent moieties; and a reagent system which causes the chemiluminescent moieties to produce light in the presence of the reagent system and the analyte in the sample.
摘要:
The present invention is directed to a DNA vaccine for immunization against HIV. The invention comprises a DNA molecule that has a sequence encoding a plurality of viral proteins capable of stimulating an immune response against HIV. The DNA molecule is rendered safe for use as a vaccine by the disruption of genes encoding reverse transcriptase, integrase, and Vif. The DNA molecule is further rendered safe by at least a partial deletion of the 3′ LTR.
摘要:
A functionalized polycyclic compound can have a structure of Formula 1 or salt, prodrug, analog, or derivative thereof, which compound can be prepared by providing a diene; reacting the diene with a dienophile under sufficient conditions for a combined Diels-Alder/acylation reaction so as to provide a polycyclic compound having a carboxylic acid; and coupling the carboxylic acid with an amine-containing compound or a hydroxyl-containing compound so as to form an amide or an ester and producing a compound having a structure of Formula 1. The compound can be used for modulating an opioid receptor, which can be conducted by administering to an opioid receptor a functionalized polycyclic compound as described herein in an effective amount to modulate the functionality of the opioid receptor. Such opioid modulation can provide a biological benefit to a subject.
摘要:
The instant application relates to nanogels or compositions that hold multivalent metal ions until some level of nanogel degradation has occurred, then slowly release the multivalent metal ions for gelation with carboxylate containing polymers. Compositions comprising such nanogels, together with polymers that can be crosslinked with multivalent metal ions, allow the deployment of such mixtures in various applications, and greatly increased gelation times.
