A series of acetylenic chalcones were evaluated for antimalarial and antitubercular activity. The antimalarial data for this series suggests that growth inhibition of the W2 strain of Plasmodium falciparum can be imparted by the introduction of a methoxy group ortho to the acetylenic group. Most compounds were more active against non-replicating than replicating cultures of Mycobacterium tuberculosis

The manuscript describes the synthesis of novel 1,2,3-triazole tethered β-lactam-chalcone bifunctional hybrids via click chemistry approach utilizing azide-alkyne cycloaddition reactions and their evaluation as anticanceragents against four human cancer cell lines. The presence of a cyclohexyl substituent at N-1 of β-lactam ring and methoxy substituents, preferably ortho on ring A and para on ring
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。

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.
