  Design, synthesis and cytotoxic evaluation of 4-methylidenepyrazolidin-3-ones

  摘要：

  Three series of new 4-methylidenepyrazolidin-3-ones with various substitution patterns were synthesized and tested for the cytotoxic activity against two human leukemia cell lines NALM-6 and HL-60 as well as MCF-7 breast cancer cell line. Several obtained methylidenepyrazolidinones exhibited high cytotoxic activity with IC50 values below 10 mu M, mainly against HL-60 leukemia cell line and two of them, 18d,e, displayed IC50 <= 5 mu M, against all tested cell lines. Structure activity relationship studies revealed that the presence of phenyl substituents on both ring nitrogen atoms and vinyl or phenyl substituents in position 5 are crucial for high activity. Selected methylidenepyrazolidinones were also tested on normal human umbilical vein endothelial cells (HUVEC) and pyrazolidinone 18a was found to be 5-fold more toxic against HL-60 than normal cells.

  The synthesis of a new library of 4,4-disubstituted 3-methylidene-3,4-dihydro-2H-chroman-2-ones applying Horner-Wadsworth-Emmons methodology for the construction of an exo-methylidene moiety is reported. Corresponding 3-diethoxyphosphorylchroman-2-ones were synthesized in a three-step reaction sequence consisting of O-methylation of ethyl 2-diethoxyphosphoryl-3-oxoalkanoates, followed by reaction of

  日期：——

  A new, versatile method for the synthesis of, so far unknown, variously substituted 4-methylidenepyrazolidin-3-ones as potential cytotoxic agents is described. Target compounds were synthesized from the corresponding 4-diethoxyphosphorylpyrazolidin-3-ones which were used as Horner-Wadsworth-Emmons reagents for the olefination of formaldehyde. 4-Phosphorylpyrazolidin-3-ones were, in turn, obtained starting from the sodium salt of ethyl 2-diethoxyphosphoryl-3-hydroxy-2-propenoate, ethyl 2-acyl-2-diethoxyphosphorylacetates, or 3-methoxy-2-diethoxyphosphorylacrylate and monosubstituted or 1,2-disubstituted hydrazines.
