Page/Page column 36, (2008/06/13)
The present invention provides Hsp90 family protein inhibitors comprising, as an active ingredient, a benzoyl compound represented by general formula (I): (wherein n represents an integer of 0 to 10; R1 represents substituted or unsubstituted lower alkoxy, substituted or unsubstituted lower alkoxycarbonyl, CONR7R8 or the like; R2 represents substituted or unsubstituted aryl, a substituted or unsubstituted aromatic heterocyclic group or the like; R3 and R5, which may be the same or different, each represent a hydrogen atom, substituted or unsubstituted lower alkyl, substituted or unsubstituted lower alkenyl or the like; and R4 and R6, which may be the same or different, each represent a hydrogen atom, halogen, substituted or unsubstituted lower alkyl, substituted or unsubstituted aryl or the like) or a prodrug thereof, or a pharmaceutically acceptable salt of said benzoyl compound or said prodrug.
A total synthesis of xestodecalactone A and proof of its absolute stereochemistry: Interesting observations on dienophilic control with 1,3-disubstituted nonequivalent allenes

A concise total synthesis of xestodecalactone A, utilizing a Diels-Alder strategy is described. The focal Diels-Alder reaction relied on an "ynoate" dienophile to rapidly assemble the required resorcylinic acid scaffold. During this study, Diels-Alder cycloaddition reactions involving 1,3-disubstituted nonequivalent allene dienophiles were studied, and some surprising results were encountered.
Mechanistic studies on the biomimetic reduction of tetrahydroxynaphthalene, a key intermediate in melanin biosynthesis

1,3,6,8-Tetrahydroxynaphthalene (T4HN) is an aromatic polyketide, serving as a general precursor of fungal melanin. Melanin biosynthesis involves two consecutive deoxygenations of T4HN, consisting of the reduction of a phenolic carbon followed by dehydrat

A biomimetic synthesis of scytalone, a simple derivative of tetralone, was reinvestigeted using NMR spectroscopy.Scytalone was formed from 1,3,6,8-tetrahydroxynaphthalene (1,3,6,8-THN) by sodium borohydride reduction only in the presence of sodium methoxi
