  Search of antitubercular activities in tetrahydroacridines: Synthesis and biological evaluation

  摘要：

  A series of 9-substituted tetrahydroacridines were synthesized by nucleophilic substitution of chloro group with different nucleophiles in 9-chlorotetrahydroacridine (2). The latter could be obtained by POCl3 mediated cyclization of the intermediate enamine, which in turn, was prepared by acid catalyzed condensation of anthranilic acid and cyclohexanone. Most of the compounds on antitubercular evaluation against M. tuberculosis H37 Rv and H37 Ra strains exhibited potent activities with MIC 6.125-0.78 mu g/mL comparable to the standard drugs.

  Linking two tacrine molecules results in a tremendous increase of activity against Plasmodia in comparison to the monomer. This finding prompted the synthesis of a library of monomeric and dimeric tacrine derivatives in order to derive structure–activity relationships. The most active compounds towards chloroquine sensitive Plasmodium strain 3D7 and chloroquine resistant strain Dd2 show IC50 values

  与单体相比，连接两个他克林分子导致抗疟原虫的活性大大增加。这一发现促进了单体和二聚他克林衍生物库的合成，以推导结构-活性关系。对氯喹敏感的疟原虫菌株3D7和对氯喹耐药的菌株Dd2最具活性的化合物在纳摩尔浓度范围内显示IC 50值，细胞毒性低，并靶向半胱氨酸蛋白酶falcipain-2，这对寄生虫的生长至关重要。

  amination protocol is described for the synthesis of N-alkyltacrines and analogs. The Josiphos ligand CyPFtBu was found to provide optimum yields: 16 examples are given. Compared to the typical high-temperature nucleophilic aromatic substitution (NAS) routes, Pd-catalyzed aminations proceed at significantly lower reaction temperatures, and enable the synthesis of otherwise inaccessible products.

  In the search for potential new anticancer drugs, an efficient synthesis of bis-tetrahydroaminoacridine (bis-tacrine) and its congeners was accomplished by bis-amination of 9-chlorotetrahydroacridine and its congeners under heated conditions.

  The critical chlorides were efficiently prepared from o-aminoaromatic acids and cycloketones in-situ in the presence of phosphorus oxychloride. In-vitro cytotoxic evaluation of the compounds was carried out against a panel of 60 human cancer cell lines. Among them, butyllinked bis-tacrine (5b) exhibited the strongest cytotoxic profile with GI50 (concentration causing 50% growth inhibition) values of approximately 0.04-0.08 μM against breast, colon, melanoma and non-small lung cancer cells. Congeners bearing a longer alkyl chain were on average 30- to 100-fold less cytotoxic against these cancer cells. Shorter connecting alkyl chains of bis-tacrine or its congeners dramatically decreased the cytotoxic effects.

  Compound 5b has been selected for further biological evaluation of its anticancer profile.

  在寻找潜在新抗癌药物的过程中，通过9-氯四氢喹啉及其同系物的双胺化，在加热条件下成功合成了双-四氢喹啉（双-他克林）及其同系物。这些关键氯化物是通过邻氨基芳香酸和环酮在磷氯化氢存在下原位高效制备的。对这些化合物进行了体外细胞毒性评估，针对60种人类癌细胞系。其中，丁基连接的双-他克林（5b）在乳腺癌、结肠癌、黑色素瘤和非小细胞肺癌细胞中表现出最强的细胞毒性，GI50（引起50%生长抑制的浓度）值约为0.04-0.08μM。具有较长烷基链的同系物对这些癌细胞的毒性平均降低了30到100倍。双-他克林或其同系物较短的连接烷基链显著降低了细胞毒性效果。化合物5b已被选中进一步评估其抗癌特性。

  Leishmaniasis is one of the most neglected diseases in modern times, mainly affecting people from developing countries of the tropics, subtropics and the Mediterranean basin, with approximately 350 million people considered at risk of developing this disease. The incidence of human leishmaniasis has increased over the past decades due to failing prevention and therapeutic measures—there are no vaccines and chemotherapy, which is problematic. Acridine derivatives constitute an interesting group of nitrogen-containing heterocyclic compounds associated with numerous bioactivities, with emphasis to their antileishmanial potential. The present work builds on computational studies focusing on a specific enzyme of the parasite, S-adenosylmethionine decarboxylase (AdoMet DC), with several 1,2,3,4-tetrahydro-acridines emerging as potential inhibitors, evidencing this scaffold as a promising building block for novel antileishmanial pharmaceuticals. Thus, several 1,2,3,4-tetrahydroacridine derivatives have been synthesized, their activity against Leishmania (Leishmania) infantum promastigotes evaluated and a structure–activity relationship (SAR) study was developed based on the results obtained. Even though the majority of the 1,2,3,4-tetrahydroacridines evaluated presented high levels of toxicity, the structural information gathered in this work allowed its application with another scaffold (quinoline), leading to the obtention of N1,N12-bis(7-chloroquinolin-4-yl)dodecane-1,12-diamine (12) as a promising novel antileishmanial agent (IC50 = 0.60 ± 0.11 μM, EC50 = 11.69 ± 3.96 μM and TI = 19.48).

  利什曼病是现代最被忽视的疾病之一，主要影响热带、亚热带和地中海盆地的发展中国家人群，约有3.5亿人可能患上该病。由于预防和治疗措施的失败，人类利什曼病的发病率在过去几十年中增加了，目前没有疫苗和化疗，这是一个问题。吖啶衍生物是一类氮杂环化合物，与众多生物活性相关，尤其是它们的抗利什曼病潜力。本研究基于对寄生虫酶S-腺苷甲硫氨酸脱羧酶（AdoMet DC）的计算研究，发现多种1,2,3,4-四氢-吖啶可能是潜在的抑制剂，表明该支架是新型抗利什曼病药物的有前途的构建块。因此，合成了多种1,2,3,4-四氢吖啶衍生物，评估了它们对利什曼原虫（利什曼原虫）幼虫的活性，并根据所得结果开展了结构-活性关系（SAR）研究。尽管大多数评估的1,2,3,4-四氢吖啶衍生物表现出高毒性，但本研究收集的结构信息使其可以与另一个支架（喹啉）结合使用，导致获得N1，N12-双（7-氯喹啉-4-基）十二烷基-1,12-二胺（12）作为有前途的新型抗利什曼病药物（IC50 = 0.60±0.11μM，EC50 = 11.69±3.96μM和TI = 19.48）。
