  摘要：

  使用点击化学（铜催化叠氮化物-炔烃 1,3-偶极环加成）合成含硒醌基 1,2,3-三唑，并针对六种类型的癌细胞系进行评估：HL-60（人早幼粒细胞白血病细胞） ）、HCT-116（人结肠癌细胞）、PC3（人前列腺细胞）、SF295（人胶质母细胞瘤细胞）、MDA-MB-435（黑色素瘤细胞）和OVCAR-8（人卵巢癌细胞）。一些化合物显示 IC 50值 < 0.3 μM。还使用非肿瘤细胞（例如外周血单核（PBMC）、V79 和 L929 细胞）测定了所评估的醌的细胞毒性潜力。NAD(P)H:醌氧化还原酶 1 (NQO1) 的机制作用也得到了阐明。这些化合物可以为更有效的抗癌药物开发和递送提供有前途的新先导衍生物，并且代表了报道的最活跃的拉帕酮类之一。

• Potent naphthoquinones against antimony-sensitive and -resistant Leishmania parasites: Synthesis of novel α- and nor-α-lapachone-based 1,2,3-triazoles by copper-catalyzed azide–alkyne cycloaddition

  Continuing our screening program for novel anti-parasite compounds, we synthesized seven 1,4-naphthoquinones coupled to 1,2,3-triazoles, five nor-beta-lapachone-based 1,2,3-triazoles and ten alpha-lapachone-based 1,2,3-triazoles. These and other naphthoquinonoid compounds were evaluated for their activity against promastigote forms of antimony-sensitive and -resistant strains of Leishmania infantum (syn. Leishmania chagasi) and Leishmania amazonensis. The toxicity of these compounds to mammalian cells was also examined. The substances were more potent than an antimonial drug, with IC50 values ranging from 1.0 to 50.7 mu M. Nor-alpha-lapachone derivatives showed the highest antileishmanial activity, with selectivity indices in the range of 10-15. These compounds emerged as important leads for further investigation as antileishmanial agents. Additionally, one of these compounds exhibited cross-resistance in Sb-resistant Leishmania and could provide a molecular tool for investigating the multidrug resistance mechanisms in Leishmania parasites.

  New naphthoquinone derivatives were synthesized and assayed against bloodstream trypomastigote forms of Trypanosoma cruzi, the etiological agent of Chagas' disease. The compounds were rationalized based on hybrid drugs and appear as important compounds against this parasite. From nor-lapachol were prepared five substituted ortho-naphthofuranquinones, a non-substituted para-naphthofuranquinone, a new oxyrane and an azide and from alpha-lapachone a new non-substituted para-naphthofuranquinone. Other five substituted ortho-naphthofuranquinones recently designed as cytotoxic, were also evaluated. The most active compounds were the ortho naphthofuranquinones 3-(4-methoxyphenylamino)-2,3-dihydro-2,2-dimethylnaphtho[1,2-b]furan-4,5-dione and 3-(3-nitrophenylamino)-2,3-dihydro-2,2-dimethylnaphtho[1,2-b]furan-4,5-dione with trypanocidal activity higher than that of benznidazole, the standard drug. The compounds were rationalized based on hybrid drugs and appear as important compounds against T. cruzi. The trypanocidal activity of these substances endowed with redox properties representing a good starting point for a medicinal chemistry program aiming the chemotherapy of Chagas' disease.

  In our continued search for novel trypanocidal compounds, twenty-six derivatives of para-and orthonaphthoquinones coupled to 1,2,3-triazoles were synthesized. These compounds were evaluated against the infective bloodstream form of Trypanosoma cruzi, the etiological agent of Chagas disease. Compounds 17-24, 28-30 and 36-38 are described herein for the first time. Three of these novel compounds (28-30) were found to be more potent than the standard drug benznidazole, with IC50/24 h values between 6.8 and 80.8 mu M. Analysis of the toxicity to heart muscle cells led to LC50/24 h of <125, 63.1 and 281.6 mu M for 28, 29 and 30, respectively. Displaying a selectivity index of 34.3, compound 30 will be further evaluated in vivo. The electrochemical properties of selected compounds were evaluated in an attempt to find correlations with trypanocidal activity, and it was observed that more electrophilic quinones were generally more potent.
