摘要:
The invention relates to a process for the preparation of 10-deacetyl-N-debenzoyl-paclitaxel (I)
a synthon useful for the preparation of taxanes with antitumour activity, and intermediates for the preparation thereof. The invention also discloses a process for the preparation of Docetaxel starting from said compound of formula (I).
摘要:
The present invention relates to a new crystalline form of Cabazitaxel, herein designated as form G, obtained by crystallization of Cabazitaxel from acetonitrile or from mixtures of acetonitrile and water. The new crystalline form G of the invention is endowed with several advantageous properties as compared to the previously disclosed forms of Cabazitaxel.
摘要:
The present invention relates to new crystalline forms of Cabazitaxel of formula (I).
Specifically, the present invention provides four new crystalline solvate forms of Cabazitaxel, designated as form S2 (solvate with 2-methyltetrahydrofuran), form S4 (solvate with tert -butyl acetate), form S5 (solvate with dimethylcarbonate) and form S6 (solvate with N-methyl-2-pyrrolidinone). A further object of the present invention are processes for the preparation of the above mentioned crystalline forms. The crystalline solvate forms of the invention are especially useful for the preparation of Cabazitaxel, Cabazitaxel salts, and polymorphic forms thereof.
摘要:
The present invention refers to an amorphous form of a thiocolchicine derivative, IDN 5404, to a process for producing it and to pharmaceutical compositions thereof. The amorphous form is characterised by the XRPD pattern, DSC profile and/or TG/DTA profile.
摘要:
The present invention relates to a new anhydrous crystalline form of Cabazitaxel of formula (I), designated as form H.
A further object of the present invention is a processes for the preparation of the above mentioned form H by recrystallization of Cabazitaxel from a mixture of decanoyl- and octanoyl triglycerides or from glycerol trioctanoate. Form H of Cabazitaxel is useful for the preparation of Cabazitaxel, Cabazitaxel salts, and polymorphic forms thereof. It is also particularly useful as a medicament, especially for the treatment of cancers.
