  DNA cleavage by di- and trihydroxyalkylbenzenes. Characterization of products and the roles of O2, Cu(II), and alkali

  摘要：

  Several 5-alkyl-1,3-dihydroxybenzene (5-alkylresorcinol, 1) and 6-alkyl-1,2,4-trihydroxybenzene (2) derivatives were prepared and used to study the mechanism by which such compounds effect Cu(II)-dependent DNA strand scission. Comparison of the methyl, n-pentyl, n-undecyl, and n-hexadecyl derivatives in each structural series indicated that the efficiency of DNA cleavage increased with increasing length of the alkyl substituent. DNA cleavage by the 5-alkylresorcinols appears to involve initial oxygenation of the benzene nucleus, a process that occurs readily at alkaline pH in the presence of Cu2+ and O-2. The resulting trihydroxylated benzenes mediate DNA cleavage in a reaction dependent on the presence of both Cu2+ and O-2. The mechanism appears to involve reduction of CU2+ by the trihydroxybenzene moiety in 2, with subsequent formation of reactive oxygen species. The ability of catalase and dimethyl sulfoxide to suppress DNA strand scission is consistent with the intermediacy of H2O2 and (OH)-O-. in the DNA strand scission process.

  For the sake of establishment of a versatile synthetic method for benzo [c] phenanthridine alkaloids, improvement of the Robinson synthetic method was examined. Thirteen chalcones (7a-m) were prepared by condensation of two acetophenone derivatives (15 and 16) with eleven benzaldehyde derivatives (19a-k) as fundamental starting materials. Hydrocyanation of these chalcones (7a-l) except one (7m) gave the corresponding 2, 4-bisaryl-4-oxobutyronitriles (8a-l). Eleven 2, 4-bisaryl-4-oxobutyramides (9a-k) were also prepared.

  为了建立一种通用的苯并[c]菲啶生物碱合成方法，对Robinson合成方法进行了改进。通过将两个乙酰苯衍生物（15和16）与十一种苯甲醛衍生物（19a-k）缩合，制备了十三种查尔酮（7a-m）作为基本起始材料。除了一个查尔酮（7m）外，这些查尔酮（7a-l）的氰化反应得到了相应的2,4-双芳基-4-氧代丁腈（8a-l）。还制备了十一种2,4-双芳基-4-氧代丁酰胺（9a-k）。

  moiety, the optimal activity was reached with either an allyl or a 1-butenyl group in conjugation with the benzene ring. The compounds 5 and 19 exerted better neuroprotective effects against epilepsy in vitro (cell) and in vivo (mouse) models. This study provides valuable data for further exploration and application of these compounds as potential anti-seizure medicines.
