Method for purifying docetaxel
-
Paragraph 0042-0044, (2019/07/04)
The invention discloses a method for purifying docetaxel. A docetaxel solid precipitates from a dichloromethane and toluene mixed solution. The purifying method has the advantages of great reduction of the single content of every impurity in docetaxel, introduction of few impurities, improvement of the purity of the product, and high yield, and is very suitable for industrial large-scale production, and the obtained product meets preparation demands, and can be directly used to prepare a docetaxel injection.

By-product 9a exhibited potent cytotoxicity against both SK-OV-3 and A549 cell lines. The structure of 9a was characterized using 1D and 2D NMR experiments and confirmed by synthesis to afford a diastereomeric mixture (16a) that was identical to 9a, as well as a pair of diastereomers (R)-16b and (S)-16c. The preliminary SAR study demonstrated that analogs with an (R)-configuration were slightly more potent than analogs with an (S)-configuration. In addition, α,α-gem-dimethyl analogs 16g-i were the most potent analogs in this series, exhibiting similar potency to docetaxel and greater potency than Taxol against the SK-OV-3 cell line. For the A549 cell line, analogs 16g-i were more potent (>65-fold) than both docetaxel and Taxol.

A simple, efficient, and alternative synthetic route for docetaxel with better control on the protection-deprotection sequence has been developed. The process is easily scalable and commercially viable, and critical impurities can be controlled efficiently. For the first time, absolute configuration of docetaxel was determined unambiguously by single-crystal X-ray diffraction.

Lu, Hong-Fu,Sun, Xun,Xu, Liang,Lou, Li-Guang,Lin, Guo-Qiang
experimental part, p. 482 - 491 (2009/09/06)
A series of novel fluorinated docetaxel analogues have been synthesized and evaluated in vitro and in vivo. Incorporated one, two or three fluorine atom(s) either at both meta position on C-2 benzolate and 3′-N-tert-butyloxyl group or only at 3′-N-tert-butyloxyl group has resulted in potent analogues which have comparable or superior in vitro and in vivo cytotoxicity to docetaxel. Among them, compounds 14d and 14e have displayed more potent cytotoxicity than docetaxel both in human cancer cell line SK-OV-3 in vitro and in human non-small cell lung cancer A549 xenografts in vivo. Preliminary data show that compound 14a has reduced acute animal toxicity in mice compared with docetaxel.

Taxotere by esterification with stereochemically 'wrong' (2S,3S)- phenylisoserine derivatives

Cyclically protected anti (2S,3S) phenylisoserines on esterification with baccatin III derivatives afford Taxotere and taxol precursors with the syn (2'R, 3'S) side chain.

The electrochemical reduction of 7α -iodo docetaxel at E- 1.3V vs. SCE in methanol in the presence of lithium chloride and hydrochloric acid leads predominantiy to 7-deoxy-ocetaxel 9. When the electroreduction is conducted at E-1.7V vs. SCE in the presenc
Improved protection and esterification of a precursor of the taxotere and taxol side chains

, p. 5185 - 5188 (2007/10/02)
(4S,5R)-N-BOC-2,2-dimethyl-4-phenyl-5-oxazolidinecarboxylic acid 8 was prepared and efficiently esterified by conveniently protected baccatins 9a,b. Smooth deprotection in formic acid gave the N-deprotected intermediates of Taxotere and taxol. This protocol did not generate any epimerization at C-2′ and constitutes a pratical method to prepare Taxotere, taxol and analogs.
