A Stereoisomers, see Fig. 2 b Glc glucose Rha rhamnose strated by a spectrophotometric method 96 . Heart microsomes were used in the study of antioxidant and metal chelating properties of a large group of flavonoids 97 . The catechol structure in ring B and the presence of the 2,3-double bond and 3-OH group were the structural features identified to be important for antioxidant activity. Additionally, it was stressed that the 3-OH group might constitute a chelation site for Fe2+ ions. Foti et...

Fig. 5 Structures of selected drugs and chemicals appearing in this review two leukemic resistant cell lines L121C and L5178 and in human adenocarcinoma cell line KB-V-1 169 . Barbieri et al. 170 demonstrated that quinolizidinyl derivatives of phenothiazine increased doxorubicin (77) cytotoxicity in resistant ovarian cancer cells (A2780-DX3). The presence of the rigid quinolizidine ring in the structure of the studied compounds seemed to be favorable for their anti-MDR activity. Recent studies...
