Y. Ueda et al., NOVEL, WATER-SOLUBLE PHOSPHATE DERIVATIVES OF 2'-ETHOXY CARBONYLPACLITAXEL AS POTENTIAL PRODRUGS OF PACLITAXEL - SYNTHESIS AND ANTITUMOR EVALUATION, Bioorganic & medicinal chemistry letters, 5(3), 1995, pp. 247-252
Three new phosphate derivatives of paclitaxel-2'-ethylcarbonate 4a, 4b
, and 4c, have been synthesized and evaluated for in vivo antitumor ac
tivity. All were soluble in water and two derivatives 4a and 4b were f
ound to exhibit in vivo antitumor activity, comparable to paclitaxel i
n the M109 murine tumor model.
