Trisubstituted and tetrasubstituted pyrazolines as a novel class of cell-growth inhibitors in tumor cells with wild type p53
摘要:
Derivatives with scaffolds of 1,3,5-tri-substituted pyrazoline and 1,3,4,5-tetra-substituted pyrazoline were synthesized and tested for their inhibitory effects versus the p53(+/+) HCT116 and p53 (/) H1299 human tumor cell lines. Several compounds were active against the two cell lines displaying IC50 values in the low micromolar range with a clearly more pronounced effect on the p53(+/+) HCT116 cells. The compound class shows excellent developability due to the modular synthesis, allowing independent optimization of all three to four key substituents to improve the properties of the molecules.

A new series of tridentate P,N,O ligands having hard and soft donor atoms derived from chiral amino alcohols were developed and employed in the Cu(II)-catalyzed conjugate addition of diethylzinc to substituted chalcones. The asymmetric additions to a variety of substituted chalcones afforded products in excellent yields and good to excellent enantioselectivities up to 97% ee. (c) 2008 Elsevier Ltd.
