| 546101000 | Each of the three cyclos is six-membered (e.g., benzoquinolines, etc.) | 8 |
| 20140179923 | NEW LIGANDS OF THE BENZO[H]QUINOLINE CLASS AND TRANSITION METAL COMPLEXES CONTAINING THEM AND USE OF SAID COMPLEXES AS CATALYSTS - A new class of ligands derived from benzo[h]quinoline are described and these ligands are used to prepare several novel transition metal complexes. The complexes are preferably of the group VIII transition metals iron, ruthenium or osmium, with the benzo[h]quinoline ligands acting as tridentate ligands. The complexes described are proved to be very active catalysts for the reduction of ketones and aldehydes to alcohols, via hydrogen transfer and hydrogenation reactions. These compounds hence can be usefully employed as catalysts in said reduction reactions. | 06-26-2014 |
| 546102000 | Acridines (including hydrogenated) | 3 |
| 20150031889 | ULTRA-SENSITIVE CHEMILUMINESCENT SUBSTRATES FOR ENZYMES AND THEIR CONJUGATES - New chemiluminescent compounds, stable in aqueous buffers, for use in biological assaying include acridane-based compounds and 1,2-dioxetanes. Among the new acridane-based compounds are water-soluble acridanes, enhancer coupled acridanes, bis and tris-acridanes as well as acridane-1,2-dioxetanes. Among the new 1,2-dioxetanes are electron deficient group-containing dioxetanes and tethered bis-1,2-dioxetanes. The 1,2-dioxetanes are useful as substrates for various enzymes. The acridanes can be admixed with an oxidizing agent, an aqueous buffer and, optionally, a stabilizer to form a substrate or reagent formulation useful for assaying, inter alia, HRP. | 01-29-2015 |

| 546108000 | Phenanthridines (including hydrogenated) | 2 |
| 20130178630 | PROCESS FOR MAKING HCV PROTEASE INHIBITORS - Efficient processes for making HCV protease inhibitors are described. In one embodiment, the process uses novel idazolide derivatives of vinyl-ACCA. | 07-11-2013 |
| 546109000 | Unsaturated ring bonded directly to ring carbon of the six-membered hetero ring | 1 |
| 20130079522 | DIHYDROETHIDINE ANALOGUES AND USES THEREOF - Tracers for imaging distribution of reactive oxygen species (ROS) are disclosed. The tracers include radiolabeled dihydroethidine (DHE) analogues. Further disclosed are uses of the compounds, including methods of imaging tissue distribution of ROS in vivo by positron emission tomography (PET). Methods of synthesizing the compounds are also disclosed. | 03-28-2013 |
| 546110000 | Chalcogen or -C(=X)-, wherein X is chalcogen, attached directly to the six membered hetero ring by nonionic bonding | 2 |
| 20110269967 | AROMATIC AMIC ACIDS OR AMIC ESTERS AND COMPOSITIONS - Novel amic acids and amic esters can be thermally converted into corresponding arylene diimides. These amic acids and amic ester can be used as precursors to prepare semiconducting thin films that can be used in various articles including thin-film transistor devices that can be incorporated into a variety of electronic devices. In this manner, the arylene diimides need not be coated out of solvent in which they may be insoluble, but they can be generated in situ from a solvent-soluble, easily coated amic acid or amic ester. | 11-03-2011 |
| 20140171646 | AMORPHOUS FORMS OF PALONOSETRON HYDROCHLORIDE - Amorphous and polymorphic of palonosetron hydrochloride are disclosed that can be characterized by X-ray powder diffraction patterns, thermal properties, purity and methods of manufacture. These forms of palonosetron hydrochloride can be produced from solution or by solid state interconversions. The forms can be used in pharmaceutical formulations: particularly preferred uses of these formulations are in prevention and treatment of nausea and emesis arising from chemotherapy or postoperative side effects. The forms can optionally be used as mixtures of the crystalline and/or amorphous forms. | 06-19-2014 |
