  Curcuminoid analogs with potent activity against Trypanosoma and Leishmania species

  摘要：

  The natural curcuminoids curcumin (1), demethoxycurcumin (2) and bisdemethoxycurcumin (3) have been chemically modified to give 46 analogs and 8 pairs of 1: 1 mixture of curcuminoid analogs and these parent curcuminoids and their analogs were assessed against protozoa of the Tryponosoma and Leishmania species. The parent curcuminoids exhibited low antitrypanosomal activity (EC50 for our drug-sensitive Trypanosoma brucei brucei line (WT) of compounds 1, 2 and 3 are 2.5, 4.6 and 7.7 mu M, respectively). Among 43 curcuminoid analogs and 8 pairs of 1: 1 mixture of curcuminoid analogs tested, 8 pure analogs and 5 isomeric mixtures of analogs exhibited high antitrypanosomal activity in sub-micromolar order of magnitude. Among these highly active analogs, 1,7-bis(4-hydroxy-3-methoxy-phenyl)hept-4-en-3-one (40) was the most active compound, with an EC50 value of 0.053 +/- 0.007 mu M; it was about 2-fold more active than the standard veterinary drug diminazene aceturate (EC50 0.12 +/- 0.01 mu M). Using a previously characterized diminazene-resistant T. b, brucei (TbAT1-KO) and a derived multi-drug resistant line (B48), no cross-resistance of curcuminoids was observed to the diamidine and melaminophenyl arsenical drugs that are the current treatments. Indeed, curcuminoids carrying a conjugated keto (enone) motif, including 40, were significantly more active against 7: b. brucei B48. This enone motif was found to contribute to particularly high trypanocidal activity against all Trypanosoma species and strains tested. The parent curcuminoids showed low antileishmanial activity (EC50 values of compounds 1 and 2 for Leishmania mexicana amastigotes are 16 +/- 3 and 37 +/- 6 mu M. respectively) while the control drug, pentamidine, displayed an EC50 of 16 +/- 2 mu M. Among the active curcuminoid analogs, four Compounds exhibited EC50 values of less than 5 mu M against Leishmania major promastigotes and four against L mexicana amastigotes. No significant difference in sensitivity to curcuminoids between L. major promastigotes and L. mexicana amastigotes was observed. The parent curcuminoids and most of their analogs were also tested for their toxicity against human embryonic kidney (HEK) cells. All the curcuminoids exhibited lower toxicity to HEK cells than to T b. brucei bloodstream forms and only one of the tested compounds showed significantly higher activity against HEK cells than curcumin (1). The selectivity index for T b. brucei ranged from 3-fold to 1500-fold. The selectivity index for the most active analog, the enone 40, was 453-fold. (C) 2009 Elsevier Masson SAS.

  β-二酮部分参与四氢姜黄素的抗氧化机制。

  摘要：

  我们研究了姜黄素和姜黄素的主要代谢产物之一四氢姜黄素（THC）对叔丁基过氧化氢诱导的红细胞膜重影的脂质过氧化的抑制作用。结果表明，四氢大麻酚显示出比姜黄素更大的抑制作用。为了研究抗氧化活性的机制，我们检查了几种抑制剂的作用，例如抗氧化剂，羟基自由基清除剂，1O2猝灭剂和金属离子螯合剂。考虑到所有抑制剂均不能抑制膜过氧化，因此THC必须清除自由基，例如叔丁氧基和过氧基。为了阐明THC的抗氧化机理，特别是β-二酮部分的作用，将二甲基化的THC与由2,2'-偶氮双（2，4-二甲基戊腈）。检测到四个氧化产物，其中三个被鉴定为3,4-二甲氧基苯甲酸，3'，4'-二甲氧基苯乙酮和3-（3,4-二甲氧基苯基）-丙酸。第四氧化产物似乎是不稳定的中间体，尚未确定其详细结构。这些结果表明，THC的β-二酮部分必须通过在β-二酮部分中的两个羰基之间的活性亚甲基碳上的CC键的裂解来显示抗氧化活性。由于四氢大麻酚是

  A number of curcumin analogues were prepared and evaluated as potential androgen receptor antagonists against two human prostate cancer cell lines, PC-3 and DU-145, in the presence of androgen receptor (AR) and androgen receptor coactivator, ARA70. Compounds 4 [5-hydroxy-1,7-bis(3,4-dimethoxyphenyl)-1,4,6-heptatrien-3-one], 20 [5-hydroxy-1,7-bis[3-methoxy-4-(meth-oxycarbonylmethoxy)phenyl]-1,4,6-heptatrien-3-one], 22 [7-(4-hydroxy-3-methoxyphenyl)-4-[3(4-hydroxy-3-methoxyphenyl)acryloyl]-5-oxohepta-4,6-dienoic acid ethyl ester], 23 [7-(4-hydroxy-3-methoxyphenyl)-4-[3-(4-hydroxy-3-methoxyphenyl)acryloyl]5-oxohepta-4,6-dienoic acid], and 39 [bis(3,4-dimethoxyphenyl)-1,3-propanedione] showed potent antiandrogenic activities and were superior to hydroxyflutamide, which is the currently available antiandrogen for the treatment of prostate cancer. Structure-activity relationship (SAR) studies indicated that the bis(3,4-dimethoxyphenyl) moieties, the conjugated beta-diketone moiety, and the intramolecular symmetry of the molecules seem to be important factors related to antiandrogenic activity. The data further suggest that the coplanarity of the beta-diketone moiety and the presence of a strong hydrogen bond donor group were also crucial for the antiandrogenic activity, which is consistent with previous SAR results for hydroxyflutamide analogues. When the pharmacophoric elements of dihydrotestosterone (DHT) and compound 4 are superposed, the resulting construct implies that the curcumin analogues may function as a 17alpha-substituted DHT. Compounds 4, 20, 22, 23, and 39 have been identified as a new class of antiandrogen agents, and these compounds or their new synthetic analogues could be developed into clinical trial candidates to control androgen receptor-mediated prostate cancer growth.
