Ra. Aitken et al., SYNTHESIS AND ANTITUMOR-ACTIVITY OF NEW DERIVATIVES OF FLAVONE-8-ACETIC ACID (FAA) .1. 6-METHYL DERIVATIVES, Archiv der pharmazie, 329(11), 1996, pp. 489-497
A range of 17 derivatives of flavone-8-acetic acid (FAA) with a B-meth
yl substituent have been prepared and their anti-tumour activity evalu
ated in vitro against a panel of human and murine tumour cell lines an
d in vivo against MAC 15A. While many of the compounds show activity c
omparable to FAA in vitro, this essentially disappears in vivo, possib
ly due to degradation before the compounds can reach the tumour site.
