摘要:
The invention concerns novel camptothecin analogues and in particular products corresponding to the following formulae: (+)-5-ethyl-9, 10-difluoro-5-hydroxy-4, 5,13,15-tetrahydro-1H, 3H-oxepino[3',4':6, 7]indolizino[1,2-b] quinoline-3,15-dione; (+)-1-[9-chloro-5- ethyl-5-hydroxy-10-methyl-3, 15-dioxo-4,5,13, 15-tetrahydro-1H,3H-oxepinol[3' ,4':6,7]indolizino [1,2-b]quinoline-12-ylmethyl] -4-methyl-hexahydropyridinium chloride; their application as medicine, pharmaceutical compositions containing them and their use for producing antitumoral, antiviral or antiparasitic medicines. The invention also concerns a novel synthesis intermediate of said products and a method for preparing said intermediate.
摘要:
The invention concerns novel 2-aminopyridine derivatives having an activity inhibiting NO-synthase enzymes producing nitrogen monoxide NO and/or trapping reactive forms of oxygen, the methods for preparing them, pharmaceutical compositions containing them and their therapeutic uses, particularly their use as NO-synthase inhibitors and for trapping reactive forms of oxygen whether selectively or not.
摘要:
The invention concerns novel 2-(iminomethyl)amino-phenyl derivatives, their preparation, their application as medicines and compositions containing them.
摘要:
The present invention is directed to imidazolyl derivatives of formula (I) where the substituents are defined in the specification, which are useful as agonists or antagonists of somatostatin receptors.
摘要:
The invention concerns the use of pyrido-thieno-triazolo-diazepins for preparing a medicine for treating pathological conditions or diseases involving one of the growth hormone release inhibiting factor receptors. The invention also concerns novel pyrido-thieno-triazolo-diazepins and therapeutic compositions containing them.
摘要:
The invention concerns novel camptothecin tetracyclic analogues of formula (I), preparation methods, applications as medicines and pharmaceutical compositions containing them. Said analogues, among which figures in particular 3-hydroxy-3-(4-oxo-4,6-dihydroindolizino [1,2-b] quinoline-2-yl)pentanoic acid, have a powerful biological activity for inhibiting topoisomerase I and/or topoisomerase II.
摘要:
The invention concerns the use of ylides of phosphorus of general formula (I') in which R'1, R'2, R'3, R'4, R'5 represent different variable groups, as a slightly nucleophilic base. The invention also concerns novel ylides of general formula (I) in which R1, R2 and R3 and R4 represent different variable groups and R5 represents a polymeric support.
