In order to discover novel hypoxia-inducible factor 1 (HIF-1) inhibitors for the cancer metastasis treatment, 68 new aryl carboxamide compounds were synthesized and evaluated for their inhibitory effect by dual luciferase-reporter assay. Based on five rounds of investigation on structure-activity relationships step by step, compound 30m was discovered as the most active inhibitor (IC50 = 0.32 μM) with no obvious cytotoxicity (CC50 > 50 μM). It effectively attenuated hypoxia-induced HIF-1α protein accumulation and reduced transcription of vascular epidermal growth factor in a dose-dependent manner, which was further demonstrated by its inhibitory potency on capillary-like tube formation, angiogenesis of zebrafish as well as cellular migration and invasion. Importantly, compound 30m exhibited antimetastatic potency in breast cancer lung metastasis in the mice model, indicating its promising therapeutic potential for prevention and treatment of tumor metastasis. These results definitely merit attention for further rational design of more efficient HIF-1 inhibitors in the future.
Decarbonylative Methylation of Aromatic Esters by a Nickel Catalyst
Okita, Toshimasa,Muto, Kei,Yamaguchi, Junichiro
supporting information, p. 3132 - 3135 (2018/05/28)
A Ni-catalyzed decarbonylative methylation of aromatic esters was achieved using methylaluminums as methylating agents. Dimethylaluminum chlorides uniquely worked as the methyl source. Because of the Lewis acidity of aluminum reagents, less reactive alkyl esters could also undergo the present methylation. By controlling the Lewis acidity of aluminum reagents, a chemoselective decarbonylative cross-coupling between alkyl esters and phenyl esters was successful.
Rh(III)-catalyzed cyclization reaction of azoles with alkynes: Efficient synthesis of azole-fused-pyridines

Decarbonylative C-H coupling of azoles and aryl esters: Unprecedented nickel catalysis and application to the synthesis of muscoride A
Amaike, Kazuma,Muto, Kei,Yamaguchi, Junichiro,Itami, Kenichiro
supporting information; experimental part, p. 13573 - 13576 (2012/10/08)
A nickel-catalyzed decarbonylative C-H biaryl coupling of azoles and aryl esters is described. The newly developed catalytic system does not require the use of expensive metal catalysts or silver- or copper-based stoichiometric oxidants. We have successfully applied this new C-H arylation reaction to a convergent formal synthesis of muscoride A.

Five-membered heterocyclic ureas are capable of forming the unfolded conformer without preorganization by using the intramolecular hydrogen bond, and are suitable for the DDA hydrogen-bonding modules. In contrast, six-membered heterocyclic ureas are desta
Design and synthesis of novel heterobiaryl amides as metabotropic glutamate receptor subtype 5 antagonists
Kulkarni, Santosh S.,Newman, Amy Hauck
, p. 2074 - 2079 (2007/10/03)
A series of heterobiaryl amides was designed and synthesized as novel mGluR5 antagonists. The synthesis using palladium catalyzed Suzuki-Miyaura cross-coupling reactions provided an array of compounds with a range of in vitro activities. In particular, compound 9e, 4(3,5-difluorophenyl)-N-(6-methylpyridin-1-yl)picolinamide, exhibited nanomolar affinity at the mGluR5 and will serve as a template for future drug design.

A catch-and-release strategy for the combinatorial synthesis of 4-acylamino-1,3-thiazoles as potential CDK5 inhibitors
Larsen, Scott D.,Stachew, Carl F.,Clare, Paula M.,Cubbage, Jerry W.,Leach, Karen L.
, p. 3491 - 3495 (2007/10/03)
Two-dimensional libraries of 4-acylamino-1,3-thiazoles 9 were prepared via Curtius rearrangement of 1,3-thiazole-4-carbonyl azides 6, trapping of the intermediate isocyanates with oxime resin, and thermal regeneration of the isocyanates from the washed resin in the presence of nucleophiles. Several compounds proved to be selective inhibitors of CDK5/p25 versus the closely homologous CDK2/cyclin A enzyme, with the best analogue (43) possessing over 100-fold selectivity.
