  • Title: Cysteine chloromethyl and diazomethyl ketone derivatives with potent anti-leukemic activity.
    Author: Perrey DA, Narla RK, Uckun FM.
    Journal: Bioorg Med Chem Lett; 2000 Mar 20; 10(6):547-9. PubMed ID: 10741550.
    Abstract:
    A series of cysteine diazomethyl- and chloromethyl ketone derivatives has been synthesized and evaluated against human B-lineage (Nalm-6) and T-lineage (Molt-3) acute lymphoblastic leukemia cell lines. The chloromethyl ketone compounds showed potent cytotoxicity against these cell lines, with IC50 values in the low micromolar range. The best compounds were N-acetyl-S-dodecyl-Cys chloromethyl ketone (IC50 = 2.0 microM against Nalm-6, 2.3 microM against Molt-3) and N-acetyl-S-trans,trans-farnesyl-Cys chloromethyl ketone (IC50 = 3.0 microM against Nalm-6 and 1.4 microM against Molt-3).
