Trichodermin inhibits the growth of oral cancer through apoptosis-induced mitochondrial dysfunction and HDAC-2-mediated signaling. Biomed Pharmacother 2022; 153:113351. [PMID: 35785707 DOI: 10.1016/j.biopha.2022.113351] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 06/16/2022] [Accepted: 06/24/2022] [Indexed: 11/02/2022] Open
Abstract
Trichodermin (TCD), a trichothecene first isolated from marine Trichoderma viride, is an inhibitor of eukaryotic protein synthesis. However, the potential effects of TCD on human oral squamous cell carcinoma (OSCC) cells and the underlying molecular mechanisms remain unknown. In this study, the exposure of OSCC cells (Ca922 and HSC-3 cells) to TCD suppressed cell proliferation assessed using MTT assays and colony formation assays. TCD inhibited the migration and invasion of OSCC cells (Ca922 and HSC-3 cells) through the downregulation of matrix metalloproteinase 9. After treatment of OSCC cells with TCD, the G2/M phase was arrested, caspase-related apoptosis (cleaved caspase-3 and PARP expression) was induced, and the protein level of x-linked inhibitor of apoptosis was reduced. Meanwhile, the TCD-induced cell death was reversed by the pan-caspase inhibitor Z-VAD-FMK. Furthermore, TCD diminished mitochondrial membrane potential, mitochondrial oxidative phosphorylation and glycolytic function in OSCC cells. In addition, TCD decreased the levels of histone deacetylase 2 (HDAC-2) and downstream signaling proteins, including phosphorylated STAT3 and NF-κB. Finally, TCD significantly suppressed tumor growth in a zebrafish OSCC xenotransplantation model. Overall, this evidence demonstrates that TCD is a novel promising strategy for the treatment of OSCCs.

Abstract
Some plant essential oils were reported to have antimicrobial activity and have the potential to replace chemical preservatives in food industry. In this study, the antibacterial activity and possible mechanism of Perilla frutescens essential oil (PEO) were evaluated using Enterococcus faecalis R612-Z1 as the target strain. The minimum inhibition concentration of PEO against E. faecalis was 0.5 μL/mL. The PEO solutions at the concentrations higher than minimum inhibition concentration had varying degrees of bactericidal effects against E. faecalis. With the addition of PEO, the cell membrane integrity was destroyed, the cell membrane potential was decreased, and the intracellular adenosine triphosphate loss was increased. By testing the bacterial counts and total volatile basic nitrogen contents in chicken breast meat, PEO can significantly inhibit the growth of E. faecalis. The results showed that PEO can be used as an effective natural food preservative during food storage.

Abstract
Soil-borne pathogens, including phytopathogenic fungi and root-knot nematodes, could synergistically invade vegetable roots and result in serious economic losses. The genus of Trichoderma has been proven to be a promising reservoir of biocontrol agents in agriculture. In this study, the search for antagonistic metabolites from a marine-derived fungus, Trichoderma longibrachiatum, obtained two structural series of sesquiterpenes 1-6 and cyclodepsipeptides 7-9. Notably, the novel 1 was a rare norsesquiterpene characterized by an unprecedented tricyclic-6/5/5-[4.3.1.01,6]-decane skeleton. Their structures were elucidated by extensive spectroscopic analyses, while the absolute configuration of novel 1 was determined by the comparison of experimental and calculated ECD spectra. The novel 1 and known 2 and 3 showed significant antifungal activities against Colletotrichum lagrnarium with MIC values of 8, 16, and 16 μg/mL respectively, even better than those of the commonly used synthetic fungicide carbendazim with 32 μg/mL. They also exhibited antifungal potential against carbendazim-resistant Botrytis cinerea. Cyclodepsipeptides 7-9 showed moderate nematicidal activities against the southern root-knot nematode (Meloidogyne incognita). This study constitutes the first report on the antagonistic effects of metabolites from T. Longibrachiatum against soil-borne pathogens, also highlighting the integrated antagonistic potential of marine-derived T. Longibrachiatum as a biocontrol agent.

Synthesis of Trichodermin Derivatives and Their Antimicrobial and Cytotoxic Activities. Molecules 2019; 24:molecules24203811.

Abstract
Trichothecene mycotoxins are recognized as highly bioactive compounds that can be used in the design of new useful bioactive molecules. In Trichoderma brevicompactum, the first specific step in trichothecene biosynthesis is carried out by a terpene cyclase, trichodiene synthase, that catalyzes the conversion of farnesyl diphosphate to trichodiene and is encoded by the tri5 gene. Overexpression of tri5 resulted in increased levels of trichodermin, a trichothecene-type toxin, which is a valuable tool in preparing new molecules with a trichothecene skeleton. In this work, we developed the hemisynthesis of trichodermin and trichodermol derivatives in order to evaluate their antimicrobial and cytotoxic activities and to study the chemo-modulation of their bioactivity. Some derivatives with a short chain at the C-4 position displayed selective antimicrobial activity against Candida albicans and they showed MIC values similar to those displayed by trichodermin. It is important to highlight the cytotoxic selectivity observed for compounds 9, 13, and 15, which presented average IC50 values of 2 μg/mL and were cytotoxic against tumorigenic cell line MCF-7 (breast carcinoma) and not against Fa2N4 (non-tumoral immortalized human hepatocytes).

Abstract
Trichodermol, a fungal sesquiterpene derived from the farnesyl diphosphate pathway, is the biosynthetic precursor for trichodermin, a member of the trichothecene class of fungal toxins produced mainly by the genera of Trichoderma and Fusarium. Trichodermin is a promising candidate for the development of fungicides and antitumor agents due to its significant antifungal and cytotoxic effects. It can also serve as a scaffold to generate new congeners for structure-activity relationship (SAR) study. We reconstructed the biosynthetic pathway of trichodermol in Saccharomyces cerevisiae BY4741, and investigated the effect of produced trichodermol on the host by de novo RNA sequencing (RNA-Seq) and quantitative Real-time PCR analyses. Co-expression of pESC::FgTRI5 using plasmid pLLeu-tHMGR-UPC2.1 led to trichodiene production of 683 μg L-1, while integration of only the codon-optimized FgTRI5 into the chromosome of yeast improved the production to 6,535 μg L-1. Subsequent expression of the codon-optimized cytochrome P450 monooxygenase encoding genes, TaTRI4 and TaTRI11, resulted in trichodermol, with an estimated titer of 252 μg L-1 at shake flask level. RNA-Seq and qPCR analyses revealed that the produced trichodermol downregulated the expression of the genes involved in ergosterol biosynthesis, but significantly upregulated the expression of PDR5 related to membrane transport pathway in S. cerevisiae. Collectively, we achieved the first heterologous biosynthesis of trichodermol by reconstructing its biosynthetic pathway in yeast, and the reconstructed pathway will serve as a platform to generate trichodermin analogs as potential candidates for agrochemicals and anticancer agents through further optimizations.
