Page/Page column 24; 25, (2018/06/16)
The present invention relates to a 1-phenylpropanone compound of formula (I), wherein X is CH2 or an atom selected from the group consisting of O, S and Se, n is an integer from 4 to 6, A is a substituent selected from the group consisting of 4-morpholyl, 1-piperidinyl, 4-methyl-1-piperazinyl, A being optionally substituted with a (C1-C3)alkyl or (C1-C3)acyl substituent, with the proviso that when X is CH2, n is equal to 5, for use as an antitumoral agent in the treatment of breast cancer, chronic lymphatic leukemia or neuroblastoma. The invention also concerns new 1-phenylpropanone compounds, and compounds as antitumoral agents.

We have previously reported the discovery and preliminary structure activity relationships of a series of β-aminoketones that disrupt the binding of coactivators to TR. However, the most active compounds had moderate inhibitory potency and relatively high cytotoxicity, resulting in narrow therapeutic index. Additionally, preliminary evaluation of in vivo toxicology revealed a significant dose related cardiotoxicity. Here we describe the improvement of pharmacological properties of thyroid hormone receptor coactivator binding inhibitors. A comprehensive survey of the effects of substitutents in key areas of the molecule was carried out based on mechanistic insight from the earlier report. This study revealed that both electron withdrawing and hydrophobic substituents on the aromatic ring led to higher potency. On the other hand, moving from an alkyl to a sulfonyl alkyl side chain led to reduced cytotoxicity. Finally, utilization of amine moieties having low pKa's resulted in lowered ion channel activity without any loss of pharmacological activity.
