Microwave-assisted synthesis and antioxidant activity of an imine, (E)-1-(3-bromobenzylidene)-2-phenylhydrazine

Antitumor Activity of PEGylated and TEGylated Phenothiazine Derivatives: Structure–Activity Relationship

“…The ROS production starts at the mitochondrial level due to oxidative processes, where a big part of phenothiazine derivatives is accumulated [ 50 , 51 ]. Moreover, there are studies indicating that PEG and imine units also have the ability to induce significant antioxidant activity [ 52 , 53 ].…”

(E)-5-Benzyl-7-(3,4-dimethoxybenzylidene)-3-(3,4-dimethoxyphenyl)-2-phenyl-3,3a,4,5,6,7-hexahydro-2H-pyrazolo[4,3c] Pyridine

“…The antioxidant activity evaluation for the title compound was performed by following the previously reported literatures [18][19][20] with slight modification. First, 10 mg of the title compound were dissolved in 10 mL methanol (1000 µg/mL).…”

“…Then, as much as 80 µL of DPPH solution (40 µg/mL) were transferred to lines A-G, while line H was just filled with 130 µL of methanol as a blank and the test solutions were incubated for 30 min at room temperature in the dark room. The absorbance was measured at a wavelength of 517 nm with a 96-well microplate reader and the percentage of DPPH inhibition was calculated using formulae from previous reports [18][19][20]. The IC 50 value was calculated based on the linear regression equation (y = ax + b) from the curve by plotting the Ln concentration and the percentage of inhibition (see Supplementary Materials, Table S2 and Figure S34).…”
