Abstract. Fusarium Dieback, a new and lethal insect-vectored disease can host over 300 tree species including the avocado trees. This problem has recently attracted the attention of synthetic chemist not only to develop new triazol antifungal agents but also due to severe drug resistance to “classic” triazol antifungal agents. Here, a series of novel antifungal triazoles with a p-trifluoromethylphenyl moiety were synthesized and characterized by spectroscopic and spectrometric methods. Most of the target compounds synthesized showed from modest to good inhibitory activity and less phytotoxicity in comparison with the commercially available propiconazol; in particular, compounds 7 and 13 were active against both Fusarium solani and Fusarium euwallaceae. The results showed that compounds 7, 13, and 4 have great potential to be developed as new antifungal agents because of both good antifungal activity and low phytotoxicity. SAR showed that free alcohols and not O-protected compounds significantly influence the activity. Hence, a-methyl-a-1,2,4-triazole emerged as novel compound to develop new ketone-triazole-type antifungal agents for the management of Fusarium Dieback disease Resumen. Fusarium Dieback es una nueva enfermedad letal transmitida por insectos que actúan como vectores y puede atacar a más de 300 especies de árboles, incluidos los árboles de aguacate. Recientemente, este problema ha atraído la atención de los químicos sintéticos para desarrollar nuevos agentes antifúngicos triazólicos debido a la resistencia severa que desarrollan los insectos a los agentes antifúngicos triazólicos "clásicos". Durante este trabajo, se sintetizaron nuevos triazoles antifúngicos que contienen un grupo p-trifluorometilfenilo y se caracterizaron por métodos espectroscópicos y espectrométricos. La mayoría de los compuestos diana sintetizados mostraron una actividad inhibidora de modesta a buena y menos fitotoxicidad en comparación con el propiconazol que es comercialmente disponible; en particular, los compuestos 7 y 13 mostraron ser activos contra Fusarium solani y Fusarium euwallaceae. Los resultados mostraron que los compuestos 7, 13 y 4 tienen un gran potencial para desarrollarse como nuevos agentes antifúngicos debido a la buena actividad antifúngica y su baja fitotoxicidad. SAR mostró que los alcoholes libres y no los compuestos O-protegidos influyen significativamente en la actividad. Por lo tanto, el α-metil-α-1,2,4-triazol surgió como un nuevo compuesto líder para desarrollar nuevos agentes antifúngicos tipo cetona-triazol para el tratamiento de la enfermedad Fusarium Dieback.

Novel Drug

From the discovery to the golden age of antibiotics (miracle), millions of lives have been saved. The era of negligence towards chemotherapeutic agents gave birth to drug resistance. Among all the regulators of drug resistance, drug transporters are considered to be the key regulators for multidrug resistance. These transporters are prevalent from prokaryotes to eukaryotes. Endophytes are one of the unexplored wealths of nature. Endophytes are a model mutualistic partner of plants. They are the reservoir of novel therapeutics. The present review deals with endophytes as novel drug resistance reversal agents by inhibiting the drug transporters across the genera. This review also focuses on drug transporters, and mutualistic chemical diversity, exploring drug transporter modulating potential of endophytes.
