—— | 6-aminopenicillanic acid methyl ester | 13789-47-4 | C9H14N2O3S | 230.288 |
A simple synthesis of the β -lactams 11 - 13 and 16 - 17 as novel histone deacetylase (HDAC) inhibitors is described. The key synthetic strategies involved the O-alkylation of 6-APA and the coupling reactions of freshly prepared N-carbobenzyloxy-L-prolines 5 and 6 and 6-aminopenicillanates 8 - 10 and 15 in high yields. It was found that all compounds show potent growth inhibitory activity on human tumor cell lines, the most potent compound 16 exhibiting an IC50 = 2.1 μM in vitro.
