Aims: CYP53A15, from the sorghum pathogen Cochliobolus lunatus, is involved in detoxification of benzoate, a key intermediate in aromatic compound metabolism in fungi. Because this enzyme is unique to fungi, it is a promising drug target in fungal pathogens of other eukaryotes.
Methods And Results: In our work, we showed high antifungal activity of seven cinnamic acid derivatives against C. lunatus and two other fungi, Aspergillus niger and Pleurotus ostreatus. To elucidate the mechanism of action of cinnamic acid derivatives with the most potent antifungal properties, we studied the interactions between these compounds and the active site of C. lunatus cytochrome P450, CYP53A15.
Conclusion: We demonstrated that cinnamic acid and at least four of the 42 tested derivatives inhibit CYP53A15 enzymatic activity.
Significance And Impact Of The Study: By identifying selected derivatives of cinnamic acid as possible antifungal drugs, and CYP53 family enzymes as their targets, we revealed a potential inhibitor-target system for antifungal drug development.

Chunhua loquat is a novel cultivar that effectively avoids frost damage. However, the quality characteristics of loquats are limited, and the effects of forchlorfenuron application on loquat fruit quality and bioactive substance accumulation remain unclear. In this study, forchlorfenuron was applied at concentrations of 0 (control), 10, 20, 30, and 40 mg/L to the fruit at 24 and 38 days after bloom.

Glucose is the most abundant monosaccharide and a principal substrate in biotechnological production processes. In Pseudomonas, this sugar is either imported directly into the cytosol or first oxidised to gluconate in the periplasm. While gluconate is taken up via a proton-driven symporter, the import of glucose is mediated by an ABC-type transporter, and hence both require energy.

Cinnamic Acid Sugar Ester Derivatives (CASEDs) are a class of natural compounds that exhibit several interesting biological activities. However, to date, no examples of their use in sunscreen formulations have been reported. Here, we describe the synthesis of a series of novel cinnamic acid esters of glucose (4a-g), ribose (4h) and lactose (4i) starting from the respective acetals 3.

Colistin-resistant (COLR-Ab) is an opportunistic pathogen commonly associated with nosocomial infections, and it is difficult to treat with current antibiotics. Therefore, new antimicrobial agents need to be developed for treatment. Based on this information, we investigated the antimicrobial, antibiofilm, and combination activities of -coumaric acid (-CA), ferulic acid (FA), and -methoxycinnamic acid (-MCA) against five COLR-Ab isolates.
