4-Aminoquinoline-chalcone/- N -acetylpyrazoline conjugates: Synthesis and antiplasmodial evaluation
摘要:
1H-1,2,3-triazole linked 4-aminoquinoline-chalcone/-N-acetylpyrazoline conjugates were synthesized and evaluated against cultured chloroquine (CQ) resistant strain. Antiplasmodial activities of the synthesized conjugates revealed dependence of activity on the length of the alkyl chain as well as on the presence of methoxy substituents on ring A/ring B of the chalcone. The most potent and non-cytotoxic conjugate showed comparable antiplasmodial activity with that of CQ with an IC50 value of 53.7 nM. (C) 2017 Elsevier Masson SAS. All rights reserved.

cones and 7-chloroquinoline-pyrazolines were synthesized using 1,3-dipolar cycloaddition and evaluated for their antimycobacterial and cytotoxic activities. The compound having O-methoxy substituent on ring A and p-methoxy on ring B along with pyrazoline ring exhibited moderate activity and was noncytotoxic.
使用 1,3-偶极环加成法合成了一系列 1 H -1,2,3-三唑连接的 7-氯喹啉-查耳酮和 7-氯喹啉-吡唑啉,并评估了它们的抗分枝杆菌和细胞毒活性。A环上具有O-甲氧基取代基和B环上对甲氧基以及吡唑啉环具有中等活性且无细胞毒性的化合物。
Photophysical properties and dye-sensitized solar cell studies on thiadiazole–triazole–chalcone dendrimers
Synthesis of charge-separable and hole-transporting dendrimers with chalcone at the periphery, thiadiazole as core and triazole as branching unit has been achieved through 'click' reaction. The dendrimers are used as a charge separator in dye-sensitized solar cells (DSSCs) and exhibit higher open-circuit voltage than the bare film through the suppression of back electron transfer. As the dendrimer generations increases the dimension of the dendrimer also increases, resulting in a stronger association with I-3(-) redox couple and higher open-circuit. (C) 2012 Elsevier Ltd.
