摘要:
Disubstituted lavendustin A analogs that are PTK inhibitors having antiproliferative activity are described. Preferred compounds of the present invention, without limitation, satisfy either Formula 1 or Formula 2. Currently preferred compounds ,based on in vivo biological activity, are 4'-adamantylbenzoate-1'-N-1,4-dihydroxybenzylamine and 4'-adamantylmethylbenzoate-1'-N-1,4-dihydroxybenzylamine. The present invention also provides pharmaceutical compositions comprising effective amounts of disubstituted lavendustin A analogs. Such compositions also may comprise other active ingredients, other materials conventionally used in the formulation of pharmaceutical composition, and mixtures thereof. The compounds and compositions of the present invention can be used for treating subjects to, for example, inhibit the proliferation of living cells in the treatment of proliferative diseases.
摘要:
Die Erfindung betrifft ein Verfahren zur Gewinnung von Diacetylrhein in pharmazeutisch brauchbarer Reinheit mit einem Restgehalt an unerwünschten Aloe-Emodinderivaten von insgesamt weniger als 20 ppm. Das Verfahren besteht darin, daß man Aloeemodinkomponenten des Diacetylrheins einer Flüssig-Flüssig-Verteilung und anschließender Kristallisation unterwirft und unter besonders produktschonenden Bedingungen trocknet. Die Erfindung betrifft auch das nach diesem Verfahren erhältliche Diacetylrhein und ein pharmazeutisches Mittel, das diese Verbindung enthält.
