摘要:
Disclosed are compounds of formula (IA), formula (IV) or formula (V), wherein the variables are as defined herein, and pharmaceutical compositions containing them which are useful for treating a subject with a proliferative disorder, such as cancer. The disclosed compounds and pharmaceutical compositions are also useful for treating disorders responsive to Hsp70 induction and/or natural killer induction.
摘要:
Gegenstand der vorliegenden Erfindung sind in einem ersten Aspekt Aldimine der Formel (I). Diese Aldimine eignen sich insbesondere als latente Härter in härtbaren Zusammensetzungen, insbesondere in ein- oder zweikomponentigen Isocyanatgruppen aufweisenden Zusammensetzungen. Sie lassen sich aufgrund der vorhandenen reaktiven Gruppe zu Aldimingruppen-haltigen Verbindungen der Formel (X) und (XII) umsetzen, welche ein weiterer Aspekt der vorliegenden Erfindung darstellt. Die Aldimine, bzw. die Aldimingruppen-haltigen Verbindungen, lassen sich vor allem in Kleb- und Dichtstoffe, aber auch in Beschichtungen verwenden und lassen sich leicht aus gut erhältlichen Grundstoffen herstellen und weisen eine gute thermische Stabilität auf. Ihre tertiäre Aminogruppe weist eine überraschend niedrige Basizität auf und kann unter Umständen in chemischen Reaktionssystemen eine katalytische Wirkung entfalten.
摘要:
Process for preparing imine compounds, in which a carbonyl compound is reacted with a primary amine. The imine compound obtained in this way can be reacted further with a metalalkyl and subsequently a carbonyl compound to form an imine compound.
摘要:

摘要:
A medical composition containing, as an active constituent, a nitroetheneamine derivative represented by formula (I) wherein R1 is a hydrogen atom, an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heterocyclic group, or a cyano group; R?2 and R3¿ may be each a hydrogen atom, an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heterocyclic group, or -A-R7 (wherein A is S, SO, SO¿2?, SO3, CO or CO2, and R?7¿ is a hydrogen atom, an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heterocyclic group), or may form N=CR8R9 (wherein R?8 and R9¿ are each a hydrogen atom, an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heterocyclic group, an alkoxy or aryloxy group, a cyano group, a nitro group, or -A-R?7); R4 and R5¿ may be each a hydrogen atom, an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heterocyclic group, an alkoxy group, an amino group, an aryloxy group, -A-R7 , a cyano group, an ester group or a hydroxyl group, or may form N=CR8R9; R6 is a hydrogen atom, a nitro group, a cyano group, -A-R7, an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aryl or heterocyclic group, an alkoxy group, an amino group, or a halogen atom; and further R?1, R2, R3, R4 and R5¿ may form a ring containing or not containing a heteroatom, or a salt thereof as an active constituent.
摘要:
A compound represented by the following general formula (I), its salt, its solvate or its N-oxide or prodrugs thereof: (I) wherein R1 and R2 represent each an optionally substituted cyclic group, etc.; W is a spacer having from 1 to 6 carbon atoms in its main chain; X represents -O-, etc.; A represents an optionally substituted cyclic group; Y is a spacer having from 1 to 6 carbon atoms in its main chain, etc.; and Z represents an acidic group. Because of having an activity of controlling peroxisome proliferator-activated receptors, the compounds are useful as preventives/remedies for metabolic errors such as hypercholesteremia and hyperlipoproteinemia, hyperlipemia, arteriosclerosis, hypertension, circulatory diseases, hyperphagia, ischemic heart diseases and so on, HDL cholesterol-elevating agents, LDL cholesterol and/or VLDL cholesterol-lowering agents, and drugs for relieving risk factors of diabetes and metabolic syndrome.
