  芳氧基乙基硫氰酸盐是克氏锥虫和弓形虫的有效生长抑制剂

  摘要：

  作为我们旨在寻找针对寄生虫病的新型安全化疗药物的项目的一部分，设计、合成了几种结构上与抗寄生虫药物 WC-9（4-苯氧基苯氧基乙基硫氰酸酯）相关的化合物，这些化合物在末端苯环上进行了修饰，并被评估为针对克氏锥虫（恰加斯病的病原体）和弓形虫（引起弓形体病的寄生虫）的生长抑制剂。大多数合成类似物表现出相似的抗寄生虫活性，并且比我们的先导 WC-9 稍强一些。例如，两种三氟甲基化衍生物针对细胞内克氏弓形虫表现出 10.0 和 9.2 μM的 ED 50值，而针对弓形虫速殖子表现出有效的作用（针对弓形虫的 ED 50值为 1.6 和 1.9 μM ）。此外，末端芳基位于带有硫氰酸酯基团的烷基链间位的 WC-9 类似物在非常低的微摩尔范围内对克氏弓形虫和刚地弓形虫均表现出有效的抑制作用。表明对苯基取代模式对于生物活性来说不是必需的。

  As a part of our project pointed at the search of new safe chemotherapeutic and chemoprophylactic agents against parasitic diseases, several compounds structurally related to 4-phenoxyphenoxyethyl thiocyanate (WC-9), which were modified at the terminal aromatic ring, were designed, synthesized and evaluated as antiproliferative agents against Trypanosoma cruzi, the parasite responsible of American

• Structure−Activity Relationship of New Growth Inhibitors of <i>Trypanosoma</i> <i>cruzi</i>

  Several drugs bearing the 4-phenoxyphenoxy skeleton and other closely related structures were designed, synthesized, and evaluated as antiproliferative agents against Trypanosoma cruzi, the etiologic agent of Chagas' disease. The new class of drugs was envisioned by modifying the nonpolar 4-phenoxyphenoxy moiety replacing selected aromatic protons by different groups via electrophilic aromatic substitution reactions as well as introducing a sulfur atom at the polar extreme. Of the designed compounds, sulfur-containing derivatives were shown to be potent antireplicative agents against T. cruzi. Among these drugs, 4-phenoxyphenoxyethyl thiocyanate (compound 56) proved to be an extremely active growth inhibitor of the epimastigote forms of T. cruzi and displayed an IC50 of 2.2 mu M. Under the same assay conditions, this drug was much more active than Nifurtimox, one of the drugs currently in clinical use to control this disease. This thiocyanate derivative was also a very active inhibitor against the intracellular form of the parasite at the nanomolar level. Other sulfur derivatives prepared also exhibited very potent antiproliferative action against T. cruzi. The presence of a sulfur atom at the polar extreme for this family of compounds seems to be very important for biological action because this atom was always associated with high inhibition values. 4-Phenoxyphenoxyethyl thiocyanate presents very good prospective not only as a lead drug but also as a potential chemotherapeutic agent.

  New analogues of antitubercular drug PA-824 were synthesized, featuring alternative side chain ether linkers of varying size and flexibility, seeking drug candidates with enhanced metabolic stability and high efficacy. Both alpha-methyl substitution and removal of the benzylic methylene were broadly tolerated in vitro, with a biaryl example of the latter class exhibiting an 8-fold better efficacy than the parent drug in a mouse model of acute Mycobacterium tuberculosis infection and negligible fragmentation to an alcohol metabolite in liver microsomes. Extended linkers (notably propenyloxy, propynyloxy, and pentynyloxy) provided greater potencies against replicating M. tb (monoaryl analogues), with propynyl ethers being most effective under anaerobic (nonreplicating) conditions (mono/biaryl analogues). For benzyloxybenzyl and biaryl derivatives, aerobic activity was maximal with the original (OCH2) linker. One propynyloxy-linked compound displayed an 89-fold higher efficacy than the parent drug in the acute model, and it was slightly superior to antitubercular drug OPC-67683 in a chronic infection model.
