Article Citation - WoS: 7Citation - Scopus: 7Neo-Clerodanes From Teucrium Divaricatum Subsp. Divaricatum and Their Biological Activity Assessment(Elsevier, 2023) Aydoğan, Fadime; Ali, Zülfiqar; Zülfiqar, Fazila; Karaalp, Canan; Khan, Ikhlas A.; Bedir, ErdalFifteen neo-clerodane diterpenoids (1–15), including two undescribed glycosides, teudivaricosides A (1) and B (2), together with a known iridoid glycoside (16) and a phenylpropanoid glycoside (17) from the whole plant of Teucrium divaricatum subsp. divaricatum were isolated. Their structures were determined by spectral data analysis including 1D and 2D NMR and HRESIMS. Neo-clerodane diterpenoids were evaluated for their anti-inflammatory, and antimicrobial activities. None of them showed significant antimicrobial activity against various bacterial and fungal strains (up to 20 µg/mL). All tested compounds were inactive up to the highest tested concentration of 50 µM on iNOS inhibitory activity.Article Citation - WoS: 51Citation - Scopus: 58Synthesis, Cytotoxic and Antimicrobial Activities of Novel Cobalt and Zinc Complexes of Benzimidazole Derivatives(Elsevier Ltd., 2017) Apohan, Elif; Yılmaz, Ülkü; Yılmaz, Özgür; Serindağ, Ayfer; Küçükbay, Hasan; Yeşilada, Özfer; Baran, YusufIn this study fourteen novel cobalt (II) or zinc (II) complexes of benzimidazoles were synthesized from the 1-(4-substitutedbenzyl)-1H-benzimidazoles and CoCl2·6H2O or ZnCl2. Cytotoxic activities of novel complexes were investigated against lung cancer cells (A549) and BEAS-2B. Three of the examined compounds (1, 4 and 5) showed high cytotoxic activity against A549. While the IC50 of the cisplatin was 2.56 μg/mL for A549 cells at 72 h, the IC50 values of compounds 1, 4 and 5 were 1.97, 1.87 and 1.9 μg/mL, respectively. IC50 values of these compounds for BEAS-2B cells were higher than the IC50 values for A549. While the IC50 values for BEAS-2B cells were 59.8, 24.5 and 32.67 μg/mL, respectively, the IC50 of the cisplatin was determined as 2.53 μg/mL in the present work. Three of the compounds have also high antimicrobial activity against all the microorganisms used.
