HC Toxin is a cell-permeable, reversible inhibitor of histone deacetylases (HDACs) (IC50 = 30 nM). Through its effects on HDACs, HC toxin has been shown to up-regulate the expression of 15-lipoxygenase-1 in colorectal cancer cells and induce fetal hemoglobin in human primary erythroid cells. HC Toxin is a cyclic tetrapeptide first isolated from H. carbonum (now C. carbonum), a pathogen of maize.
Zearalenone-13C18is intended for use as an internal standard for the quantification of zearalenone by GC- or LC-MS. Zearalenone is a mycotoxin that has been found inFusariumand has estrogenic activities.1It binds to human estrogen receptor α (ERα) and ERβ (IC50s = 9 and 5.8 nM, respectively).2Zearalenone induces precocious development of mammary tissues in young female pigs and prepucial enlargement in young male pigs.3Zearalenone (1.5-5 mg kg of diet) induces hyperestrogenism in pigs. It also induces degeneration of meiotic chromatin in oocytes and reduces fertility in pigs when administered at a dose of 200 μg kg.4Zearalenone has been found as a contaminant in wheat, maize, and barley and livestock feeds.3,4
12-oxo-13-HOME is an oxylipin derived from linoleic acid .1It is formedviaa 13-HpODE intermediate that is produced by lipoxygenase-mediated metabolism of linoleic acid.2,3,112-oxo-13-HOME has been found in corn and sunflower seedlings.4 1.Ogorodnikova, A.V., Gorina, S.S., Mukhtarova, L.S., et al.Stereospecific biosynthesis of (9S,13S)-10-oxo-phytoenoic acid in young maize rootsBiochim.

Rimsulfuron (DPX-E9636) is a sulfonylurea herbicide specifically designed for postemergence application in maize crops. This compound effectively targets and manages grasses as well as certain types of broadleaf weeds.
Sphynolactone-7 (SPL7) acts as an agonist for the Striga hyposensitive to light receptor 7 (ShHTL7) found in the parasitic plant Striga hermonthica. SPL7 selectively targets ShHTL7 with an IC50 of 0.31 µM, demonstrating higher specificity compared to ShHTL2-6, ShHTL9-10, and the strigolactone receptor AtD14 at a concentration of 10 µM, though it still inhibits ShHTL8 and ShHTL11 with IC50s of 1.2 and 7.8 µM, respectively. This compound triggers fatal germination of Striga hermonthica seeds in the absence of a host by inducing suicidal germination at a minimum effective concentration of 10 fM. Additionally, SPL7 can reduce the emergence of this obligate parasite from the soil and alleviate Striga hermonthica-induced senescence in maize when applied at a 10 nM concentration to the soil of maize and Striga hermonthica seed co-cultures.
1,2-Dilinoleoyl-3-palmitoyl-rac-glycerol is a triacylglycerol featuring linoleic acid at the sn-1 and sn-2 positions and palmitic acid at the sn-3 position. Present in various vegetable oils such as poppy seed, hazelnut, maize, and olive, this compound (3% w v) effectively reduces scald development in Delicious apples when applied right after harvest, with results observed after six months of storage.
1,2-Dilinoleoyl-3-stearoyl-rac-glycerol, a triacylglycerol, comprises linoleic acid at the sn-1 and sn-2 positions and stearic acid at the sn-3 position. It is present in various plant oils such as soybean, poppy seed, maize, evening primrose, and blackcurrant.
14-Methyl palmitic acid methyl ester is a methylated fatty acid methyl ester identified in A. indica leaf extract, S. alboflavus TD-1, and as a less prominent constituent in biodiesel from C. sorokiniana microalgae. It acts as a volatile agent emanating from maize, impeding the growth of F. verticillioides in a dose-responsive manner. Additionally, this compound is utilized as a reference standard for quantifying 14-methyl palmitic acid in diverse foods via GC-MS. [Matreya, LLC. Catalog No. 1614]
