| 20090137826 | Method for preparing 4beta-amino-4'-demethyl-4-desoxypodophyllotoxin - The invention relates to a method for synthesizing 4β-amino-4′-demethyl-4-desoxypodophyllotoxin of formula (1), characterized by comprising the following successive steps: a) reacting, in a pure weak acid or in a mixture consisting of acid, water and of organic solvent, without another solvent, at a temperature higher than the ambient temperature, thiourea with 4β-halogenoacetamido-4′-demethyl-4-desoxypodophyllotoxin, and; b) recovering the 4β-amino-4′-demethyl-4-desoxypodophyllotoxin. | 05-28-2009 |
| 20100202975 | NOVEL FLUORESCENT DERIVATIVES OF POLYAMINES, METHOD FOR PREPARING SAME AND APPLICATIONS THEREOF AS DIAGNOSIS TOOLS IN THE TREATMENT OF CANCEROUS TUMORS - The invention relates to novel fluorescent derivatives of polyamines having a benzoxadiazole group, to a method for preparing the same and to the use thereof as diagnosis tools for emphasising the polyamine transport system in cancerous cells in order to adapt the treatment thereof, and thus for selecting patients carrying such tumours in order to adapt their treatment. The derivatives are of the formula (I) or a pharmaceutically acceptable salt thereof, in which: R | 08-12-2010 |
| 20100280263 | Process for the Synthesis of Anticancer (Poly) Aminoalkylaminoacetamide Derivatives of Epipodophyllotoxin - The present invention describes a new process for the preparation of (poly)aminoalkylaminoacetamide compounds of epipodophyllotoxin useful for their applications in therapeutics as anticancer agents. This process comprises a step of condensation of a primary-amine-containing reactant, whose amine functions are not protected, with β-chloroacetamido-4′-epipodophyllotoxin in a polar aprotic organic solvent. | 11-04-2010 |
| 20110021791 | Method for preparing 4B-amino-4'-demethyl-4-desoxypodophyllotoxin - The invention relates to a method for synthesizing 4β-amino-4′-demethyl-4-desoxypodophyllotoxin of formula (1), characterized by comprising the following successive steps: a) reacting, in a pure weak acid or in a mixture consisting of acid, water and of organic solvent, without another solvent, at a temperature higher than the ambient temperature, thiourea with 4β-halogenoacetamido-4′-demethyl-4-desoxypodophyllotoxin, and; b) recovering the 4β-amino-4′-demethyl-4-desoxypodophyllotoxin. | 01-27-2011 |
| 20110053967 | (POLY) AMINOACETAMIDE DERIVATIVES OF EPIPODOPHYLLOTOXIN THEIR PROCESS OF PREPARATION AND THEIR APPLICATIONS IN THERAPEUTICS AS ANTICANCER AGENTS - The present invention relates to novel podophyllotoxin derivatives substituted in the 4-position by a substituted (poly)aminoalkylaminoacetamide chain, to their process of preparation and to their use as medicament as anticancer agents. | 03-03-2011 |
