  Synthesis of novel monocarbonyl curcuminoids, evaluation of their efficacy against MRSA, including ex vivo infection model and their mechanistic studies

  摘要：

  In continuation of our effort to improve the physiological stability and the antibacterial activity of curcuminoids against drug-resistant bacteria, a series of novel monocarbonyl curcuminoids were synthesized and screened for antibacterial activity against S. aureus and E. coli strains. These curcuminoids showed potent antibacterial activity against both methicillin-sensitive and methicillin-resistant strains of S. aureus with MIC values 2-8 and 4-16 mu g/mL, respectively. They also exhibited moderate potency against E. coll. strains. The four most active curcuminoids (7d, 7i, 7m, and 7p) were on further investigation found to be very stable under physiological conditions, non-hemolytic, and non-toxic toward mammalian cells up to 150 mu g/mL concentration. Mechanistic studies revealed that these curcuminoids displayed potent bactericidal activity by targeting cell membranes. Further, in an ex vivo mammalian co-culture infection model study, remarkably, the curcuminoids 7i and 7p were able to clear the internalized bacteria in mammalian cells and the activity was found to be superior to conventional antibiotics such as vancomycin and linezolid. Therefore, the present study affords us water-soluble, stable, non-toxic curcuminoids that may serve as lead molecules for development as antibacterial agents against MRSA infections.

  查尔酮-O-烷基胺衍生物作为对抗阿尔茨海默氏病的多功能药物的开发。

  摘要：

  设计，合成和评估了一系列新颖的查耳酮-O-烷基胺衍生物，作为多功能抗阿尔茨海默氏病药物。根据实验结果，化合物23c对乙酰胆碱酯酶（IC50 = 1.3±0.01μM）和丁酰胆碱酯酶（IC50 = 1.2±0.09μM）均表现出良好的抑制作用。此外，23c表现出选择性的MAO-B抑制活性，IC50值为0.57±0.01μM。化合物23c也是潜在的抗氧化剂和神经保护剂。另外，化合物23c可以抑制自诱导的Aβ1-42聚集。此外，化合物23c是一种选择性金属螯合剂，可以抑制和分解Cu2 +诱导的Aβ1-42聚集，这在进一步的透射电子显微镜图像的支持下得以实现。此外，23c可能在体外穿过血脑屏障，并改进了东pol碱诱导的体内记忆障碍。分子模型研究表明23c可以结合AChE，BuChE，Aβ1-42和MAO-B的活性位点。综上所述，这些结果表明化合物23c可能是用于治疗AD的潜在多功能剂。

  In this work, we have developed a novel series of multi-target-directed ligands to address low levels of acetylcholine (ACh), oxidative stress, metal ion dysregulation, and the misfolded proteins. Novel apigenin-donepezil derivatives, naringenin-donepezil derivatives, genistein-donepezil derivatives and chalcone-donepezil derivatives have been synthesized, in vitro results showed that TM-4 was a reversible

  The inhibition of FLT-3 activity is an interesting target for the treatment of acute myeloid leukemia (AML). The serendipitous identification of FLT-3 inhibitors from a CK1/gamma-secretase programme provided compounds with dual inhibitory activity. We analyzed the structure-activity relationship of these inhibitors and derivatized them to arrive at compounds with reduced impact on gamma-secretase activity and enhanced FLT-3 inhibition.
