Thus Selleck was definitely selling the incorrect isomer to the general marketplace for at least the month ending Jan. 24, 2012 and possibly until late April 2012. However, via a normal ordering process we obtained 10 mg of their lot #S-101402 on Dec. 22, 2011 and 50 mg of the same lot on January 24, 2012. We only analyzed one lot from each of these three vendors. Until we receive confirmation of the details, we cannot name either supplier.
We have been advised by the Knapp laboratory that they received "bosutinib" from two different suppliers, but to date we have not received confirmation as to which suppliers product (or both suppliers) is the subject of the X-ray structure.
three vendors on the above list purchased incorrect bosutinib from LC Laboratories. We do not know if they also obtained and re-sold incorrect (or correct) bosutinib from other sources. Moreover, Sellecks website displayed an NMR of the incorrect isomer as recently as late April or early May 2012. Thus there is at least an 18th vendor, and possibly a 19th, that sold an incorrect bosutinib isomer.
