Interference No. 103,675 an NMR spectrum for the compound prepared in CX 54 (CX 56). Thereafter, Dr. Chen gave both his own NMR spectrum, including a depiction of the proposed structural formula, and a sample to Ms. Huang for purposes of performing NMR analysis on said sample (CX 98; CR 642, 643). Ms. Huang obtained an NMR spectrum which she initialed and dated on 12/17/91 (CX 57). The exhibit is captioned at the top of the page "CHEN 32044-010 12/16/91." Nevertheless, the date on the right hand side of the spectrum is "13-5-93" or May 13, 1993. Chen et al. have not even addressed let alone explained this discrepancy. Dr. Chen testified that the NMR machines used at Bristol-Myers Squibb did not generate the handwritten notes (CR 577-78; CR 580, lines 2-8; CR 583, lines 2-5; CR 584, lines 3-13; CR 594, line 16 through CR 595, line 6). A sample of the compound was submitted by Dr. Chen to the Compound Control Department in January 1992. Ms.Kissel assigned the sample the Bristol-Myers Squibb compound number BMS-183582-01 (CX 60). The sample was determined to have the ability to polymerize and stabilize tubulin (CR 128; CX 182, 183). The sample was also determined to have in vitro cytotoxicity against certain cancer cells (CR 141; CX 203). The results were provided to Dr. Chen who then provided them to Dr. Farina. Ms. Huang's conclusion that the spectra she obtained were 115Page: Previous 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 NextLast modified: November 3, 2007
