Ra. Aitken et al., SYNTHESIS AND ANTITUMOR-ACTIVITY OF 6-METHYL DERIVATIVES OF FLAVONE-8-ACETIC ACID (FAA), Bioorganic & medicinal chemistry letters, 4(19), 1994, pp. 2313-2316
A range of 16 derivatives of flavone-8-acetic acid (FAA) with a 6-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.
