Discovery of β-Carboline oxadiazole derivatives as fungicidal agents against rice sheath blight

A series of β-carboline oxadiazoles were synthesized, and their fungicidal activities and mechanism of action against rice sheath blight caused by Rhizoctonia solani was evaluated. The results showed that all of these compounds exhibited significant in vitro fungicidal activity. Significantly, compound 5i (EC50 = 4.2 μg/mL) displayed the best efficacy and superior fungicidal activity compared to validamycin A (EC50 = 197.6 μg/mL). Moreover, the in vivo test also demonstrated that compound 5i could effectively control rice sheath blight and showed higher in vivo protective and curative activities against R. solani than validamycin A. Preliminary mechanism studies revealed that compound 5i caused the loss of mitochondrial membrane potential, reactive oxygen species accumulation, cell membrane destruction, and DNA synthesis interference. These findings indicated that compound 5i displayed superior fungicidal activities against R. solani and could be a potential fungicidal candidate against rice sheath blight.

Synthesis and antitumoral activity of novel 3-(2-substituted-1,3,4-oxadiazol-5-yl) and 3-(5-substituted-1,2,4-triazol-3-yl) β-carboline derivatives

Several novel 1-substituted-phenyl β-carbolines bearing the 2-substituted-1,3,4-oxadiazol-5-yl and 5-substituted-1,2,4-triazol-3-yl groups at C-3 were synthesized and evaluated for their in vitro anticancer activity. The assay results pointed thirteen compounds with growth inhibition effect (GI50 50 values lying in the nanomolar concentration range (GI50 = 10 nM for both compounds). The 1-(N,N-dimethylaminophenyl)-3-(5-thioxo-1,2,4-triazol-3-yl) β-carboline (8g) was the most active compound, showing particular effectiveness on lung (GI50 = 0.06 μM), ovarian and renal cell lines. The potent anticancer activity presented for synthesized compounds 7a, 7h, and 8g, together with their easiness of synthesis, makes these compounds promising anticancer agents.
