Antiprotozoal activity of chloroquinoline based chalcones
摘要:
A new series of chloroquinoline based chalcones were synthesized and evaluated for in vitro antiamoebic and antimalarial activities. The results showed that out of fifteen compounds, four were found to be more active against the Entamoeba histolytica; while one compound was moderatively active compared to the standard drug metronidazole (IC50 = 1.46 mu M). In contrast, in vitro antimalarial activity against the chloroquine-sensitive (3D7) strain of P. falciparum indicated relatively low activity when compared to controls such as chloroquine and quinine (IC50 = 0.0065 mu M and 0.14 mu M, respectively). The toxicological studies of these compounds on human breast cancer MCF-7 cell line showed that all the compounds were non-toxic at the concentration range of 1.56-50 mu M.

A series of simple quinoline–chalcone conjugates have been synthesized and evaluated for their nucleolytic activity. The compounds 3c and 3d exhibited promising DNA binding and DNA photocleavage studies.
36 Novel heterocyclic chalcone derivatives were synthesized and tested for their anti‐bacterial activity. Some compounds presented good anti‐microbial activities against Gram‐positive bacteria (including the multidrug‐resistant clinical isolates). This class of compounds presented high potency against Streptococcus mutans, among which the derivatives F2 with an MIC of 2 µg/mL was as active as the standard

A series of triazolothiadiazepines were synthesized by the reaction of 4-substituted-5-aryl-1,2,4-triazoles and chalcones using p-TsOH as catalyst under solvent-free microwave irradiation conditions. Structure of all the prepared compounds were elucidated by elemental, IR, 1H NMR and mass spectral data.
