CYTISINE-LINKED ISOFLAVONOID ANTINEOPLASTIC AGENTS FOR THE TREATMENT OF CANCER

, (2019/01/04)
Cytisine-linked isoflavonoids, or pharmaceutically acceptable salts thereof or pharmaceutically acceptable compositions thereof, are useful for the treatment of conditions in which cells have a reliance on peroxisomal HSD17B4 to degrade very long chain fatty acids and provide necessary energy for cell proliferation, such as is seen in colorectal cancer and prostate cancer, for example.

Cytisine-linked isoflavonoids (CLIFs) inhibited PC-3 prostate and LS174T colon cancer cell proliferation by inhibiting a peroxisomal bifunctional enzyme. A pull-down assay using a biologically active, biotin-modified CLIF identified the target of these agents as the bifunctional peroxisomal enzyme, hydroxysteroid 17β-dehydrogenase-4 (HSD17B4). Additional studies with truncated versions of HSD17B4 established that CLIFs specifically bind the C-terminus of HSD17B4 and selectively inhibited the enoyl CoA hydratase but not the d-3-hydroxyacyl CoA dehydrogenase activity. HSD17B4 was overexpressed in prostate and colon cancer tissues, knocking down HSD17B4 inhibited cancer cell proliferation, suggesting that HSD17B4 is a potential biomarker and drug target and that CLIFs are potential probes or therapeutic agents for these cancers.

The regioselectivity of the oxidation of three monosubstituted olefins, 6-phenoxyhex-1-ene, hex-1-ene and styrene, by iodosobenzene in the presence of various Fe-, Mn- or Cr-tetraaryl-porphyrins, was studied.It was found that, besides epoxides, known products from such systems, allylic alcohols and aldehydes were formed, the latter not being derived from the corresponding epoxides.The relative importance of these reactions greatly depends upon both the metal and porphyrin constituents of the catalyst.More particularly, the competition between epoxidation and allylic hydroxylation can be efficiently controlled by non bonded interactions between the olefin and porphyrin substituents.No hydroxylation of the aromatic rings and no oxidative dealkylation of the ether function was detected.
MONOOXYGENASE-LIKE OXIDATIONS OF OLEFINS AND ALKANES CATALYZED BY MANGANESE PORPHYRINS : COMPARISON OF SYSTEMS INVOLVING EITHER O2 AND ASCORBATE OR IODOSYLBENZENE

A biphasic system using a manganese porphyrin as a catalyst and sodium ascorbate as a reducing agent is able to activate dioxygen and to oxidize olefins selectively into epoxides and alkanes into alcohols and ketones.Its properties and specifities are shown to be different from those of the manganese porphyrin-iodosylbenzene system, suggesting that a manganese -oxo complex is not involved in these O2-dependent oxidations.
