- Design and optimization of potent and orally bioavailable tetrahydronaphthalene raf inhibitors
-
Inhibition of mutant B-Raf signaling, through either direct inhibition of the enzyme or inhibition of MEK, the direct substrate of Raf, has been demonstrated preclinically to inhibit tumor growth. Very recently, treatment of B-Raf mutant melanoma patients with a selective B-Raf inhibitor has resulted in promising preliminary evidence of antitumor activity. This article describes the design and optimization of tetrahydronaphthalene-derived compounds as potent inhibitors of the Raf pathway in vitro and in vivo. These compounds possess good pharmacokinetic properties in rodents and inhibit B-Raf mutant tumor growth in mouse xenograft models.

- PROCESS FOR PREPARATION OF 2-AMINOTETRALIN DERIVATIVES AND INTERMEDIATES THEREOF
-
The present invention is to efficiently and simply prepare an optically active 7-substituted-2-aminotetralin with industrial advantage. In the process, a 7-substituted-2-tetralone or its bisulfite adduct is reduced with a microorganism to an optically active 7-substituted-2-tetralol. Then, a sulfonyl group is introduced to the hydroxy group to form an optically active 7-substituted-2-sulfonyloxytetralin. Then, with inversion of the configuration, a nitrogen substituent is introduced using a nitrogen nucleophile to form an optically active 2,7-substituted tetralin. Furthermore, if necessary, the nitrogen substituent is converted into a non-substituted amino group. Thus, an optically active 7-substituted-2-aminotetralin or its salt is prepared.
