Autor: Mitsuhiro Yonehara, Masanobu Uchiyama, Machiko Hirayama, Nagao Kobayashi, Atsuya Muranaka, Asami Saito

Publikováno v: Chemistry Letters. 40:714-716

A novel tribenzotetraazaporphyrin with a fused azulene ring was synthesized via mixed condensation reaction of 5,6-dicyanoazulene and 3,6-dibutoxyphthalonitrile. The macrocycle exhibited several in...

Publikováno v: Synlett. 2006:1583-1585

An optically active bicyclo[3.3.0]octane ring was synthesized by an intramolecular C-H insertion reaction. Upon treatment with a catalytic amount of Rh 2 (S-DOSP) 4 , a chiral-auxiliary-containing diazoester underwent a C-H insertion reaction to give

Improvement of water-solubility of biarylcarboxylic acid peroxisome proliferator-activated receptor (PPAR) δ-selective partial agonists by disruption of molecular planarity/symmetry

Autor: Makoto Makishima, Yuichi Hashimoto, Hiroyuki Miyachi, Minoru Ishikawa, Jun Ichi Kasuga, Mitsuhiro Yonehara

Publikováno v: Bioorganicmedicinal chemistry. 18(20)

To elucidate the molecular basis of peroxisome proliferator-activated receptor (PPAR) δ partial agonism, X-ray crystal structures of complexes of the PPARδ ligand-binding site with partial agonists are required. Unfortunately, reported PPARδ parti

beta-Naphthoflavone analogs as potent and soluble aryl hydrocarbon receptor agonists: improvement of solubility by disruption of molecular planarity

Autor: Yuji Fujita, Yuichi Hashimoto, Minoru Ishikawa, Tomomi Noguchi-Yachide, Mitsuhiro Yonehara, Masashi Tetsuhashi

Publikováno v: Bioorganicmedicinal chemistry. 18(3)

The physiological role of aryl hydrocarbon receptor (AhR) is not yet fully understood, and investigation is hampered by the limited solubility of reported AhR ligands in aqueous media. To achieve improved solubility, we focused on our previous findin
