Abstract: One of the main problems affecting the world is food scarcity which is occasioned by different
causes, including difficult climatic conditions, economic and technical limitations, infrastructure
and transportation, food safety and insecurity, and diseases caused by microorganisms (phytopathogens)
such as Fusarium oxysporum whose damage triggers a series of irreversible effects on
several crops, causing economic losses worldwide. Given the complexity that the chemical control of
phytopathogens represents, various investigations have been refocused on exploring new biomimetic
actions that lead to synthesizing new compounds with potential antifungal activity. In addition, computational
chemistry and chemoinformatics tools (molecular docking and molecular dynamics) make
it possible to understand and often predict these compounds' mechanisms of action, thereby formulating
Quantitative Structure-Activity Relationship (QSAR) models. These strategies have established an
important advance in designing new molecules capable of inhibiting pathogens from a rational development
of antifungal compounds. This article reviewed the novel synthetic bioisosteres of secondary
metabolites biologically active against Fusarium oxysporum, their synthetic protocols, and the strategies
implemented for its control. The most innovative examples of this class of active organic compounds
are presented, such as N,S-dialkyl dithiocarbamates, Schiff bases, N-alkyl substituted amides,
and several heterocyclic systems with potential antifungal activity. Likewise, the use of computational
tools is discussed, showing how these results can conduce to the design of new antifungal agents.
