Synthesis and Biological Evaluation of Cytotoxic 6(7)-Alkyl-2-hydroxy-1, 4-naphthoquinones
摘要:
Various Diels Alder cycloaddition conditions have been used to optimise the preparation of cytotoxic 6-alkyl-1,4-naphthoquinones, which were subsequently transformed into 6(7)-alkyl-2-hydroxy-1,4-naphthoquinones. The compounds thus prepared were evaluated for their cytotoxic activity against several neoplastic cultured cell lines and some of them showed IC50 values below the muM level.
Accordingly, there are provided, inter alia, derivatives of seriniquinone and methods useful for the treatment of cancer, and in particular treatment of melanoma and prostate cancer.

strategy used to obtain the quinonederivatives was initially based on the Diels–Alder cycloaddition between myrcene and several p-benzoquinone derivatives, followed by cyclisation of the prenyl side chain in the case of anthracene-1,4-diones. The most promising compounds, displaying MIC values in the low μg/mL range, were those bearing one or two chlorine atoms attached to the quinone ring. Time-kill curves

A new procedure to obtain anthracene-1,4-diones from p-benzoquinones and myrcene, in the presence of acids, is described. The cycloaddition reaction between α-myrcene and p-benzoquinones, followed by oxidation, led to 1,4-naphthoquinones or 1,4-anthraquinones depending upon whether the Lewis acid used in the Diels-Alder reaction, was present or absent during oxidation; furthermore, traces of acid in

A series of new furoterpenyl-1,4-naphtho(anthra)quinones have been prepared via oxidative cyclization of the corresponding 2-hydroxy-3-butenyl-1,4-naphtho(anthra)quinones. Depending on the reaction conditions the 1,2-quinones or the 1,4-quinones were obtained. Several new furo-1,4-anthraquinones were also obtained by condensation of 2,3-dichloroquinones with 1,3-dicarbonyls. The compounds synthesized have been evaluated for their cytotoxicity against neoplastic cell lines, some of them being effective below the micromolar level. (c) 2006 Elsevier Ltd. All rights reserved.
