Lu, Zeyu;Peng, Bingyin;Ebert, Birgitta E.;Dumsday, Geoff;Vickers, Claudia E. research published 《 Auxin-mediated protein depletion for metabolic engineering in terpene-producing yeast》, the research content is summarized as follows. Abstract: In metabolic engineering, loss-of-function experiments are used to understand and optimize metabolism A conditional gene inactivation tool is required when gene deletion is lethal or detrimental to growth. Here, we exploit auxin-inducible protein degradation as a metabolic engineering approach in yeast. We demonstrate its effectiveness using terpenoid production First, we target an essential prenyl-pyrophosphate metabolism protein, farnesyl pyrophosphate synthase (Erg20p). Degradation successfully redirects metabolic flux toward monoterpene (C10) production Second, depleting hexokinase-2, a key protein in glucose signalling transduction, lifts glucose repression and boosts production of sesquiterpene (C15) nerolidol to 3.5 g L^-1 in flask cultivation. Third, depleting acetyl-CoA carboxylase (Acc1p), another essential protein, delivers growth arrest without diminishing production capacity in nerolidol-producing yeast, providing a strategy to decouple growth and production These studies demonstrate auxin-mediated protein degradation as an advanced tool for metabolic engineering. It also has potential for broader metabolic perturbation studies to better understand metabolism

Luan, Zhen-jie;Li, Pei-pei;Li, Duo;Meng, Xiao-ping;Sun, Jing research published 《 Optimization of supercritical-CO₂ extraction of Iris lactea seed oil: Component analysis and antioxidant activity of the oil》, the research content is summarized as follows. Iris lactea Pall. var. chinensis (Fisch.) Koidz. is a widely distributed species and the seeds of this species have been used as medicine. However, the chem. composition and biol. activities of the I. lactea seed oil (ILSO) have not been studied. In this present work, extraction time, temperature, and pressure were considered as variables and response surface methodol. based on the Box-Behnken design was utilized to identify the optimal conditions for supercritical fluid extraction of the ILSO. Furthermore, the main components (including fatty acids, unsaponifiables, and volatile components) in ILSO extracted with the above optimal conditions were identified by gas chromatog.-mass spectrometry. It was found that major fatty acids present in ILSO were linoleic acid (41.31%), oleic acid (34.74%), and docosahexaenoic acid (3.18%). The total content of sterols reached as high as the level of 87.44% in unsaponifiable matter and sterols with a content over 5% included β-sitosterol (27.14%) stigmasterol (18.38%), delta5-avenasterol (15.36%), campesterol (13.21%), and betulinicaldehyde (5.80%). The physicochem. properties of ILSO were analyzed according to Chinese national standards Total polyphenol content (TPC) and total tocopherol content of ILSO were also determined

Aconitum carmichaelii is a high-value medicinal herb widely used across China, Japan, and other Asian countries. Aconitine-type diterpene alkaloids (DAs) are the characteristic compounds in Aconitum. Although six transcriptomes, based on short-read next generation sequencing technol., have been reported from the Aconitum species, the terpene synthase (TPS) corresponding to DAs biosynthesis remains unidentified. We apply a combination of Pacbio isoform sequencing and RNA sequencing to provide a comprehensive view of the A. carmichaelii transcriptome. Nineteen TPSs and five alternative splicing isoforms belonging to TPS-b, TPS-c, and TPS-e/f subfamilies were identified. In vitro enzyme reaction anal. functional identified two sesqui-TPSs and twelve diTPSs. Seven of the TPS-c subfamily genes reacted with GGPP to produce the intermediate ent-copalyl diphosphate. Five AcKSLs sep. reacted with ent-CPP to produce ent-kaurene, ent-atiserene, and ent-13-epi-sandaracopimaradie: a new diterpene found in Aconitum. AcTPSs gene expression in conjunction DAs content anal. in different tissues validated that ent-CPP is the sole precursor to all DAs biosynthesis, with AcKSL1, AcKSL2s and AcKSL3-1 responsible for C20 atisine and napelline type DAs biosynthesis, resp. These data clarified the mol. basis for the C20-DAs biosynthetic pathway in A. carmichaelii and pave the way for further exploration of C19-DAs biosynthesis in the Aconitum species.

McCully, Kilmer S. research published 《 Chemical pathology of homocysteine VIII. Effects of tocotrienol, geranylgeraniol, and squalene on thioretinaco ozonide, mitochondrial permeability, and oxidative phosphorylation in arteriosclerosis, cancer, neurodegeneration and aging》, the research content is summarized as follows. A review. A century ago a fat-soluble vitamin from leafy vegetables, later named vitamin E, was discovered to enhance fertility in animals. Vitamin E consists of 8 isomers of tocopherols and tocotrienols, each containing chromanol groups that confer antioxidant properties and differ only in the 15-carbon saturated phytyl poly-isoprenoid side chain of tocopherols and the 15-carbon unsaturated farnesyl poly-isoprenoid side chain of tocotrienols. Although tocotrienol was first isolated from rubber plants in 1964, its importance in multiple disease processes was not recognized until two decades later, when the cholesterol-lowering and anti-cancer effects were first reported. Tocotrienol (T3) protects against radiation injury and mitochondrial dysfunction by preventing opening of the mitochondrial permeability transition pore, thereby inhibiting loss of the active site for oxidative phosphorylation, thioretinaco ozonide oxygen ATP, from mitochondria by complex formation with the active site, TR2CoO3O2NAD+H2PO4-T3. The preventive effects of tocotrienol on vascular disease, cancer, neurodegeneration and aging are attributed to its effects on cellular apoptosis and senescence. Geranylgeraniol is an important intermediate in the biosynthesis of cholesterol, and cholesterol auxotrophy of lymphoma cell lines and primary tumors is attributed to loss of squalene monooxygenase and accumulation of intracellular squalene. Geranylgeraniol and tocotrienol have synergistic inhibitory effects on growth and HMG CoA reductase activity, accompanied by reduction of membrane KRAS protein of cultured human prostate carcinoma cells. Since cholesterol inhibits opening of the mPTP pore of mitochondria, inhibition of cholesterol biosynthesis by these effects of tocotrienol and geranylgeraniol produces increased mitochondrial dysfunction and apoptosis from loss of the active site of oxidative phosphorylation from mitochondria.

Liu, Qi;Wang, Yu-Mei;Fu, Wen-Hao;Zhang, Ai-Hua research published 《 Gas chromatography coupled with mass spectrometry for the rapid characterization and screening of volatile oil of Euphorbia fischeriana Steud》, the research content is summarized as follows. Gas chromatog. (GC)-mass spectrometry is a powerful tool which is used in the anal. of volatile components in food and herbal medicine. Euphorbia fischeriana Steud., a traditional Chinese herb, has been used for thousands of years in China. Recently, scientists are exploring more on the pharmacol. action of E. fischeriana. However, so far, there is no information regarding the volatile constituents of E. fischeriana. Therefore, in this study, we aimed to investigate and characterize the global chem. ingredients of volatile oil of E. fischeriana under in vitro and in vivo conditions. In this study, an accurate and rapid GC combined with the mass spectrometric method and MassHunter tool were employed to identify the comprehensive constituents and explored the absorbed components in rat serum after oral administration of E. fischeriana. According to our results, a total of 28 compounds were identified via in vitro anal. by matching with the NIST database. Of them, the following 14 compounds were tentatively characterized in the serum samples: (-)-alpha-cedrene; (+/-)-sesquithuriferone; cedrol; acorenone; neocembrene; geranylgeraniol; abietatriene; abieta-7,13-diene; cembrenol; sclareol; Et linoleate; isopimara-7,15-dien-3-one; abietadienal; and abietinol. Most of the compounds identified were diterpenes and sesquiterpenes. These results might be useful in various pharmacol. and pharmacodynamic research, and the established method could offer valuable chem. information for bioactive volatile components characterization.

Lau, Carol P. Y.;Fung, Cathy S. H.;Wong, Kwok Chuen;Wang, Yu-Hsuan;Huang, Lin;Tsui, Stephen K. W.;Lee, Oscar K.;Kumta, Shekhar M. research published 《 Simvastatin Possesses Antitumor and Differentiation-Promoting Properties That Affect Stromal Cells in Giant Cell Tumor of Bone》, the research content is summarized as follows. Giant cell tumor of bone (GCTB) is a locally aggressive destructive bone lesion. The management of pulmonary metastasis and local recurrence after the surgical treatment of GCTB remains a challenge. Pathol., stromal cells in GCTB are known as primary neoplastic cells and are recognized as incompletely differentiated preosteoblasts. Therefore, inducing GCTB stromal cells to differentiate into cells with a mature osteoblastic phenotype may stop tumor growth and recurrence. In this study, we aimed to investigate how simvastatin, a clin. approved and commonly used statin that has been known to promote the maturation of cells of the osteogenic lineage, affects GCTB stromal cells. We found that simvastatin effectively inhibited cell viability by suppressing proliferation and by inducing apoptosis in GCTB stromal cells. Moreover, simvastatin treatment upregulated the expression of genes related to osteogenic maturation, such as runt-related transcription factor 2, osteopontin, and osteocalcin, and increased the mineralization of the extracellular matrix in GCTB stromal cells. Ingenuity pathway anal. was used to discover that the vitamin D receptor pathway was involved in the simvastatin-induced osteogenic differentiation of GCTB stromal cells by upregulating the 1,25-dihydroxyvitamin D metabolism Taken together, this in vitro study demonstrates the antitumor and differentiation-promoting effects of simvastatin on GCTB stromal cells and suggests the possibility of using simvastatin as an adjuvant therapy for GCTB. These findings support further clin. investigation of the efficacy of using simvastatin as an adjuvant therapy for GCTB to reduce recurrence and distant metastasis after surgical treatment.

Li, Feng-Xing;Ren, Shu-Jian;Li, Pei-Fang;Yang, Peng;Qu, Jin research published 《 An Endo-Selective Epoxide-Opening Cascade for the Fast Assembly of the Polycyclic Core Structure of Marine Ladder Polyethers》, the research content is summarized as follows. The rapid synthesis of marine ladder polyethers from polyepoxide precursors (in analogy with the biosynthetic pathway hypothesized by Nakanishi) is hampered by the fact that the exo-selective epoxide-opening cyclization cascade that gives THF-type polyethers is preferred over the endo-selective cascade that gives the desired products. We found that perfluoro-tert-butanol (PFTB) cooperating with 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM]BF₄) can promote endo-selective epoxide-opening cyclization reactions of trisubstituted epoxy alcs. Starting from readily accessible homochiral polyepoxy alcs. with a Me group at all the endo-cyclization sites, we were able to construct polyethers up to five consecutive fused 6-, 7-, and/or 8-membered rings in one step. Notably, mols. with the 7/7/6/6 and 7/7/6/7/6 polyether frameworks of hemibrevetoxin B and brevenal, resp., could be synthesized in 40% and 17% chem. yields.

Kruk, Jerzy;Gabruk, Michal;Kryszczak, Marian;Wasik, Piotr research published 《 Protochlorophylls in Cucurbitaceae – Distribution, biosynthesis and phylogeny》, the research content is summarized as follows. Using high-resolution chromatog. we resolved monovinyl (MV)- and divinyl (DV)-protochlorophylls (Pchls) and detected all of their side-chain homologues in the inner seed coat of Cucurbita maxima, C. pepo and their varieties. Furthermore, we analyzed other less common representatives of the Cucurbitaceae family that were found to accumulate mostly MV-Pchls. All these species and varieties showed the characteristic composition of individual Pchls. Addnl., we also detected all of the corresponding protopheophytins, which accounted for between 1.1 and 35.5% of Pchls and are supposed to be degradation products of Pchls, formed during seed storage. A pigment composition anal. of C. maxima seedlings performed during deetiolation revealed that chlorophyll (Chl) a content increased gradually, while the levels of Pchl-GG and Chl-GG, a precursor of Chl a, were low and did not change significantly. However, when the seedlings were incubated with the precursor of tetrapyrrole biosynthesis (δ-aminolevulinic acid) before illumination, the Chl-GG content increased dramatically, while synthesis of Chl a was inhibited. These data indicate that in C. maxima seedlings, Chl a is not synthesized from geranylgeranyl-pyrophoshate via Chl-GG, but rather directly from phytyl-pyrophosphate. Phylogenetic anal. of Chl synthase genes revealed that many species, including those of the Cucurbitaceae family, have two or more Chl synthase genes. This suggests that these addnl. genes, at least in some species, might encode isoforms involved in Pchl synthesis.

Although World Health Organization-approved emergency vaccines are available in many countries, the mortality rate from COVID-19 remains high due to the fourth or fifth wave and the delta variant of the coronavirus. Thus, an effective mechanistic investigation in treating this disease is urgently needed. In this work, we extracted phytochems. from two mangrove plants, Pistacia integerrima and Pandanus odorifer, assessing their potential actions against the receptor-binding domain (RBD) of the spike protein of SARS-CoV-2. The antioxidant activities of Pistacia integerrima leaves and fruits were 142.10 and 97.13 μg/mL, resp., whereas Pandanus odorifer leaves and fruits were 112.50 and 292.71 μg/mL, resp.

B.;Bhattacharya, Ankita;Smitha, Attibele Ramamurthy;Hegde, Namratha;Nagegowda, Dinesh A. research published 《 A plastid-localized bona fide geranylgeranyl diphosphate synthase plays a necessary role in monoterpene indole alkaloid biosynthesis in Catharanthus roseus》, the research content is summarized as follows. In plants, geranylgeranyl diphosphate (GGPP, C₂₀) synthesized by GGPP synthase (GGPPS) serves as precursor for vital metabolic branches including specialized metabolites. Here, we report the characterization of a GGPPS (CrGGPPS2) from the Madagascar periwinkle (Catharanthus roseus) and demonstrate its role in monoterpene (C₁₀)-indole alkaloids (MIA) biosynthesis. The expression of CrGGPPS2 was not induced in response to Me jasmonate (MeJA), and was similar to the gene encoding type-I protein geranylgeranyltransferase_β subunit (CrPGGT-I_β), which modulates MIA formation in C. roseus cell cultures. Recombinant CrGGPPS2 exhibited a bona fide GGPPS activity by catalyzing the formation of GGPP as the sole product. Co-localization of fluorescent protein fusions clearly showed CrGGPPS2 was targeted to plastids. Downregulation of CrGGPPS2 by virus-induced gene silencing (VIGS) significantly decreased the expression of transcription factors and pathway genes related to MIA biosynthesis, resulting in reduced MIA. Chem. complementation of CrGGPPS2-vigs leaves with geranylgeraniol (GGol, alc. form of GGPP) restored the neg. effects of CrGGPPS2 silencing on MIA biosynthesis. In contrast to VIGS, transient and stable overexpression of CrGGPPS2 enhanced the MIA biosynthesis. Interestingly, VIGS and transgenic-overexpression of CrGGPPS2 had no effect on the main GGPP-derived metabolites, cholorophylls and carotenoids in C. roseus leaves. Moreover, silencing of CrPGGT-I_β, similar to CrGGPPS2-vigs, neg. affected the genes related to MIA biosynthesis resulting in reduced MIA. Overall, this study demonstrated that plastidial CrGGPPS2 plays an indirect but necessary role in MIA biosynthesis. We propose that CrGGPPS2 might be involved in providing GGPP for modifying proteins of the signaling pathway involved in MIA biosynthesis.

24034-73-9, Geranylgeraniol is a diterpenoid that is hexadeca-2,6,10,14-tetraene substituted by methyl groups at positions 3, 7, 11 and 15 and a hydroxy group at position 1. It has a role as a plant metabolite, a volatile oil component and an antileishmanial agent. It is a diterpenoid and a polyprenol.

Geranylgeraniol, a precursor to geranylgeranylpyrophosphate, is an intermediate in the mevalonate pathway. Geranylgeraniol has been shown to prevent bone re-absorption, inhibition of osteoclast formation, and kinase activation in vitro. When working with statins, Geranylgeraniol can reduce the toxicity without inhibiting the cholesterol-producing effects. Geranylgeraniol has been documented to counteract the effects of fluvastatin by inhibiting activation of caspase-1 and production of IL-1. Additionally Geranylgeraniol has been found to induce apoptosis in HL-60 cells.
