A series of D- and L-tyrosine-chlorambucil analogs was synthesized as anticancer drugs for chemotherapy of breast cancer. The novel compounds were synthesized in good yields through efficient modifications of D-and L-tyrosine. The newly synthesized compounds were evaluated for their anticancer efficacy in different hormone-dependent and hormone-independent (ER+ and ER-) breast cancer cell lines. The novel analogs showed significant in vitro anticancer activity when compared to chlorambucil. Structure-activity relationship (SAR) reveals both, the influence of the length of the spacer chain and the stereochemistry of the tyrosine moiety. Interestingly, the D-and L-tyrosinol-chlorambucil derivatives with 10 carbon atoms spacer are selective towards MCF-7 (ER+) breast cancer cell line. (C) 2010 Elsevier Ltd. All rights reserved.
