摘要:
Using the cobblestone area (CA) formation inhibitory activity of human leukemic stem cell-like cells as an indicator, a fraction having the activity has been extracted from the fat-soluble fraction of Porifera, then, a compound having the activity has been isolated and purified from the aforementioned fraction, and then, the structure thereof has been determined, so that a Stelliferin compound comprising a novel compound has been identified. Moreover, it has been found that the isolated and purified Stelliferin compound significantly suppresses the niche formation of leukemic stem cell-like cells derived from human chronic myelogenous leukemia (CML) having resistance to existing antitumor agents and enhances the effects of antitumor agents on the cells. The present invention provides a pharmaceutical composition having inhibitory or suppressive activity against the niche formation of leukemic stem cells, a prophylactic agent against the recurrence of malignant tumor, which involves the combined use of other antitumor drugs, and the like.

The synthesis and in vitro and in vivo anti-breast and anti-prostate cancers activities of novel C-4 heteroaryl 13-cis retinamides that modulate Mnk-eIF4E and AR signaling are discussed. In both breast and prostate cancer cell lines, these compounds induce Mnk1/2 degradation to substantially suppress eIF4E phosphorylation. In prostate cancer cells, the compounds induce degradation of both full-length androgen receptor (fAR) and splice variant AR (AR-V7) to inhibit AR transcriptional activity. The consequences of these multiple activities resulted in inhibition of cell growth and migration and induction of apoptosis. Finally and importantly, the compounds demonstrate strong in vitro and in vivo anti-breast and anti-prostate cancer activities, with no apparent host toxicities.
