Sažetak
The novel L- and D-amino acid derivatives of hydroxyurea 5a-o were prepared by aminolysis N-(1-benzotriazolecarbonyl)-amino acid amides 4a-o with hydroxylamine. The hydantoin derivatives 6a-e, m, p were synthesized by base catalysed cyclization of amides 4, common precursor for 5 and 6. X-ray crystal structure analysis shows that the C5 atom in 6e posseses S configuration which is consistent with the configuration of the starting reagent, L-leucine. Among L-amino acid derivatives of hydroxyurea, 5h and 5i inhibited specifically murine leukemia and human T-lymphocytes (IC50: 10-19 μ M) and showed selectivity with respect to normal human fibroblasts (WI 38). D-amino acid derivatives of hydroxyurea 5m and 5o inhibited the growth of all tumor cell lines (IC50: 4.8-83.9 μ M), but not the growth of normal fibroblasts (WI 38 ; IC50: >100 μ M). Results on antiviral evaluations showed that N-(1-benzotriazolecarbonyl)-amino acid amide 4m and hydantoin 6m had marked activity against the Davis strain of CMV (4m, EC50: 3.2 μ g/mL and 6m, EC50: 4.0 μ g/mL). However, these compounds showed also rather expressed cytotoxicity (4m, CC50: 43.4 μ g/mL and 6m, CC50: 12.5 μ g/mL).
