Abstract:
Oxadiazoles are an important class of heterocyclic compounds, having broad-spectrum activity.
They were also reported as anticancer, and antioxidant agents, hence it is of significant importance to explore new oxadiazoles. A series of eleven (5-aryl-N-[4-(trifluoromethyl)phenyl]-1,3,4- oxadiazol-2-amines (6a-k) was synthesized based on the structures of reported compounds, SU-101,
IMC38525, and FTAB. All these oxadiazoles were synthesized, characterized by spectral data, and further tested against melanoma, leukemia, colon, lung, CNS, ovarian, renal, breast and prostate cancer
cell lines’ panels at a single dose of 10 μM drug concentrations. N-(4-(Trifluoromethyl)phenyl)-5-(3,4- dimethoxyphenyl)-1,3,4-oxadiazol-2-amine (6h) showed significant anticancer activity, and the most
sensitive five cell lines were NCI-H522 (% GI = 53.24), K-562 (% GI = 47.22), MOLT-4 (% GI = 43.87), LOX-IMVI (% GI = 43.62), and HL-60(TB) (% GI = 40.30). The compound, 6h revealed better
%GIs than imatinib, against 36 ce ll lines, taking 54 cell lines in common. The maximum sensitivity
was recorded against cancer cell line CCRF-CEM (% GI = 68.89) by 2-(5-(4-(trifluoromethyl) phenylamino)-1,3,4-oxadiazol-2-yl)phenol (6f). The antioxidant activity of 4-(5-(4-(trifluoromethyl)
phenylamino)-1,3,4-oxadiazol-2-yl)-2-methoxyphenol (6i) was promising with an IC50 of 15.14 μM. It was observed that the oxadiazoles reported herein showed significant anticancer and antioxidant activities.
