Synthesis and Biological Activities of C1-Substituted Acylhydrazone β-Carboline Analogues as Antifungal Candidates.

ABSTRACT: In our ongoing work to create potential antifungal agents, we synthesized and tested a group of C1-substituted acylhydrazone β-carboline analogues 9a-o and 10a-o for their effectiveness against Valsa mali, Fusarium solani, Fusarium oxysporum, and Fusarium graminearum. Their compositions were analyzed using different spectral techniques, such as ¹H/¹³C NMR and HRMS, with the structure of 9l being additionally confirmed through X-ray diffraction. The antifungal evaluation showed that, among all the target β-carboline analogues, compounds 9n and 9o exhibited more promising and broad-spectrum antifungal activity than the commercial pesticide hymexazol. Several intriguing findings re
