Only derivatives containing an electron deficient aromatic ring and capable of adopting flat conformations, optimal for π–π interactions with Fe(III)PPIX, inhibited β-hematin formation. The two most potent analogues showed nanomolar parasite activity, with little CQ cross-resistance, low cytotoxicity, and high in vitro microsomal stability. Selected analogues inhibited hemozoin formation in Plasmodium

with a new type of nitrile-bearing aromatic diacid chloride. The nitrile pendant groups of the polyamides were converted to an amidoxime functionality by a rapid hydroxylamine addition (APP-1 and APP-2). The CO2 adsorption capacities of these polyamides were measured at low pressure (1 bar) and two different temperatures (273 and 298 K) and high pressure (up to 225 bar – the highest measuring pressure
由于基于单乙醇胺(MEA)作为洗涤剂的新发电厂正在建设中,因此从化石燃料发电中捕获CO 2的成本仍然很高。众所周知,酰胺基肟可模仿MEA,而含a胺肟的多孔聚合物可为碳捕获提供可持续的解决方案。在这里,我们报告了第一个a胺肟多孔聚合物(APPs),其中具有a胺肟侧基的芳香族聚酰胺(芳族聚酰胺)是通过4,4'-氧二苯胺(ODA)和对苯二胺(p -PDA)的低温缩合反应合成的。含腈芳香族二酰氯的类型。通过快速加入羟胺(APP-1和APP-2),聚酰胺的腈侧基被转化为an胺肟官能团。一氧化碳2这些聚酰胺的吸附能力是在低压(1 bar)和两种不同温度(273和298 K)以及高压(最高225 bar –迄今为止最高的测量压力)于318 K下测量的。低压CO 2吸收APP-1的结果为0.32毫摩尔克-1相比APP-2(0.07毫摩尔克-1)在273 K,而在高压下它们表现出CO大幅增加2吸附能力表现出24

Selenium (Se) compounds are potential therapeutic agents in cancer. Importantly, the biological effects of Se compounds are exerted by their metabolites, with methylselenol (CH3SeH) being one of the key executors. In this study, we developed a new series of methylselenoesters with different scaffolds aiming to modulate the release of CH3SeH. The fifteen compounds follow Lipinski’s Rule of Five and with exception of compounds 1 and 14, present better drug-likeness values than the positive control methylseleninic acid. The compounds were evaluated to determine their radical scavenging activity. Compound 11 reduced both DPPH and ABTS radicals. The cytotoxicity of the compounds was evaluated in a panel of five cancer cell lines (prostate, colon and lung carcinoma, mammary adenocarcinoma and chronic myelogenous leukemia) and two non-malignant (lung and mammary epithelial) cell lines. Ten compounds had GI50 values below 10 μM at 72 h in four cancer cell lines. Compounds 5 and 15 were chosen for further characterization of their mechanism of action in the mammary adenocarcinoma cell line due to their similarity with methylseleninic acid. Both compounds induced G2/M arrest whereas cell death was partially executed by caspases. The reduction and metabolism were also investigated, and both compounds were shown to be substrates for redox active enzyme thioredoxin reductase.
