A series of protected and unprotected 3-O and 2, 3-di-O-alkyl derivatives of L-ascorbic acid
were synthesized and their cytotoxic activity against metastatic breast epithelial carcinoma (MCF-7)
cell line was evaluated. Cytotoxic activity evaluation indicated that compounds show moderate cytotoxic
effects on tested cell line. Some of the 2, 3-di-O-alkyl derivatives of L-ascorbic acid exhibited potent
inhibiting activity against MCF-7 cell line at micromolar concentrations. 2,3-di-O-4-chlorobenzyl-
L-ascorbic acid exhibited 4 fold more cytotoxic activity (IC50 = 34.09 μΜ ) against MCF-7 cell line
than L-ascorbic acid. 2, 3-di-O-alkyl derivatives exhibited more inhibition against MCF-7 cell line as
compared to the 3-O-alkyl derivatives of L-Ascorbic acid.

THP-1. On the other hand, antioxidant derivatives displayed albeit slight (2k, IC50 = 57.96–63.45 μM), but selective inhibitory effect toward all tumor cell lines. Thus, pro-oxidant and antioxidant properties can be used to predict the cytotoxic selectivity of drug against normal and cancer cells.
