    取代吡唑类作为吡咯霉素类似物对葡萄球菌生物膜的设计、合成和生物学评价
    摘要:
    生物膜的形成使金黄色葡萄球菌能够抵抗抗生素并引起慢性感染。几种吡咯霉素化合物是有效的抗菌剂,对葡萄球菌生物膜具有抑制作用。我们设计并合成了两个系列的取代吡唑作为吡咯霉素类似物。化合物17a、17d和17h对各种耐万古霉素粪肠球菌(VRE) 和耐甲氧西林金黄色葡萄球菌(MRSA)表现出强效抗菌活性,其中化合物17d对 MRSA (MIC = 0.0625 μg/mL)、万古霉素-中间金黄色葡萄球菌(签证) (MIC = 0.0313 μg/mL)。进一步的研究表明,化合物17h可以显着减少 MRSA 的生物膜形成,并表现出良好的选择性。还评估了体外肝微粒体稳定性,结果表明17h在人肝微粒体中代谢稳定。

  • Synthesis and cytotoxicity evaluation of regioisomeric substituted N-phenyl-3′-(chrom-4-one-3-yl)-isoxazolidines: induction of apoptosis through a mitochondrial-dependent pathway

    Regio- and stereoselective 1,3-dipolar cycloadditions of C-(chrom-4-one-3-yl)-N-phenylnitrones (5) with different mono-substituted, disubstituted and cyclic dipolarophiles were carried out to obtain substituted N-phenyl-3′-(chrom-4-one-3-yl)-isoxazolidines (7a–p, 10a–c and 12a–c). Some of the obtained isoxazolidines display significant cytotoxicity against several human cancer cell lines. The preliminary bioassay results revealed that compound 10c showed higher cytotoxicity than paclitaxel against the A549 cell line with an IC50 value of 0.7 μM. Compound 10c induces apoptosis through a mitochondrial-dependent pathway in human promyelocytic leukemia (HL-60) cells as revealed by induced apoptotic bodies' formation, DNA ladder, increased Sub-G0 DNA fraction and loss of mitochondrial membrane potential (ΔΨm) in HL-60 cells.

    Abstract

    A green, mild and efficient method for Knoevenagel condensation of 3-formylchromone/2-chlroquinoline-3-carbaldehyde with active methylene compounds such as Meldrum’s acid/ethyl cyanoacetate using biosupported cellulose sulphuric acid (CSA) in the solid-state by grinding under solvent-free condition has been developed. This method provides several advantages including environmental friendliness, shor t reaction times, high yields and a simple work-up procedure. Moreover, the CSA was successfully reused for four cycles without significant loss of activity.

    An efficient and direct approach to pyrroles was successfully developed by employing 3-formylchromones as decarboxylative coupling partners, and facilitated by microwave irradiation. The protocol utilizes easily accessible feedstocks, a catalytic amount of DBU without any metals, resulting in high efficiency and regioselectivity. Notably, all synthesized products were evaluated against five different cancer cell lines and compound 3l selectively inhibited the proliferation of HCT116 cells with an IC50 value of 10.65 μM.

    通过使用 3-甲酰基色酮作为脱羧偶联剂,并在微波辐照的帮助下,成功开发出了一种高效、直接的吡咯方法。该方法利用容易获得的原料和催化量的 DBU,不含任何属,因而具有高效率和区域选择性。值得注意的是,所有合成产物都针对五种不同的癌细胞系进行了评估,化合物 3l 选择性地抑制了 HCT116 细胞的增殖,IC50 值为 10.65 μM。
