Cedarburg Hauser Pharmaceuticals

Taxane Expertise for Cancer Therapeutic Drug Development


paclitaxel_300x250Taxanes such as Paclitaxel and Docetaxel are among the world’s largest selling and best known anticancer drugs.  The therapuetic qualities of these diterpine alkaloids that are produced by plants of the genus Taxus continue to be a popular compound for cancer drug development scientists to target.

If you are working on a taxane based development project, make sure you are working with an API development company that has the experience and expertise you need to be successful.


Put our expertise with taxanes to work for your project


Cedarburg Hauser Pharmaceuticals is an experienced, contract development and manufacturing company for active pharmaceutical ingredients (API) and pharmaceutical intermediates. 

We have unique capbilities and superior expertise in the areas of natural product extraction, isolation and purification.  We can use our experience and expertise with taxanes to help your cancer therapeutic drug development project be a success.

In fact, Hauser Chemical Research, Inc., now part of Cedarburg Hauser Pharmaceuticals, was awarded the first contracts by the National Cancer Institute in the late 1980’s to produce paclitaxel (originally called Taxol, which is now a BMS tradename) from natural sources.

We can also make many analogs of paclitaxel for research as well as clinical trials.  Contact us today to discuss your specific needs.

Patents for chemical processes to make natural & semi-synthetic paclitaxel under GMP


As a result of our extensive knowledge of taxanes, we have streamlined the chemical processes to make both natural and semi-synthetic paclitaxel under GMP. In fact, our scientists were the inventors on several key patents on these processes.

7-hexanoyltaxol and methods for preparing the same.

United States Patent 6,136,988 (October 24, 2000)

Abstract:
An antitumor compound of formula (5) ##STR1## and also provided by the present invention is a method of preparing a compound of formula (5) whereby diesterification of the alcohol groups located at the 2' and 7 positions of paclitaxel is followed by the hydrolysis of the 2' hexanoate group resulting in 7-hexanoyltaxol.

Detailed Listing:
"7-hexanoyltaxol and methods for preparing the same."  Murray, Christopher K.; Zheng, Qun Y.; Shakya, Sagar R.  United States Patent 6,136,988 (October 24, 2000).

Process for removing impurities from natural product extracts.
United States Patent 6,132,726 (October 17, 2000)

Abstract:
In general the present invention relates to a process for the removal of undesireable compounds or residues from an extract which are more polar or less polar than the desired target compound. The preferred embodiment of the present invention is a three step process and is described in detail below. The first step includes contacting a plant material that contains the desired target compound(s) with a solvent, thus producing a crude extract containing a mixture of compounds that includes, in addition to the undesireable residues, the desired target compound(s). The second step involves passing the crude extract through a series of columns containing an absorbent that retards the movement of the undesireable compounds, while allowing the desired compounds to pass. The third and final step involves drying the eluant product to achieve a final product.

Detailed Listing:
"Process for removing impurities from natural product extracts."  Daughenbaugh, Randall J.; Bailey, David T.; Gamble, William R.; Gertenbach, Dennis D.   United States Patent 6,132,726 (October 17, 2000).
