  Stilbene–Chalcone Hybrids: Design, Synthesis, and Evaluation as a New Class of Antimalarial Scaffolds That Trigger Cell Death through Stage Specific Apoptosis

  摘要：

  Novel stilbene-chalcone (S-C) hybrids were synthesized via a sequential Claisen-Schmidt-Knoevenagel-Heck approach and evaluated for antiplasmodial activity in in vitro red cell culture using SYBR Green I assay. The most potent hybrid (11) showed IC50 of 2.2, 1.4, and 6.4 mu M against 3D7 (chloroquine sensitive), Indo, and Dd2 (chloroquine resistant) strains of Plasmodium falciparum, respectively. Interestingly, the respective individual stilbene (IC50 > 100 mu M), chalcone (IC50 = 11.5 mu M), or an equimolar mixture of stilbene and chalcone (IC50 = 32.5 mu M) were less potent than 11. Studies done using specific stage enriched cultures and parasite in continuous culture indicate that 11 and 18 spare the schizont but block the progression of the parasite life cycle at the ring or the trophozoite stages. Further, 11 and 18 caused chromatin condensation, DNA fragmentation, and loss of mitochondrial membrane potential in Plasmodium falciparum, thereby suggesting their ability to cause apoptosis in malaria parasite.

  Coumarin-based novel ligands (benzylidine-bis-(4-hydroxycoumarin)-diethylamines) were easily synthesized using 4-hydroxycoumarin, aromatic aldehydes, and diethylamine. The ionic ligand structure was established by X-ray study. They are air and moisture stable ligands and have shown highly efficient catalytic activity with Pd(OAc)2 (0.1 mol % loading) in the Suzuki–Miyaura and (0.3 mol % loading) in

  使用4-羟基香豆素，芳族醛和二乙胺可以轻松合成基于香豆素的新型配体（苄基双（4-羟基香豆素）-二乙胺）。通过X射线研究建立了离子配体结构。它们是空气和湿气稳定的配体，在铃木-Miyaura中的Pd（OAc）2（0.1 mol％负载）和Mizoroki-Heck交叉偶合反应中的Pd（OAc）2（在水中或0.3 mol％负载）中显示出高效的催化活性水/乙醇混合物。钯催化剂可以有效地重复使用，而不会影响反应中各种官能团。
