Crotonyl-CoA, a high-energy acyl donor, is an intermediate in the fermentation of butyric acid, and in the metabolism of lysine and tryptophan. Crotonyl-CoA is important in the metabolism of fatty acids and amino acids. Crotonyl-CoA acts as a substrate for p300’s histone crotonyltransferase activity, competing with acetyl-CoA for p300-mediated histone acylation reactions. Crotonyl-CoA regulates global and gene-specific histone crotonylation levels in cells, with cellular concentration changes altering histone crotonylation at regulatory elements of activated genes. Crotonyl-CoA serves as the substrate for crotonyl-CoA reductase/carboxylase (CCRC)-catalyzed NADPH-mediated reduction and carbon dioxide trapping to form unusual alkylmalonyl-CoA polyketide synthase extender units. Crotonyl-CoA can be used for the research of LPS-induced inflammatory response .

ASF-006 sodium, a tetrapodal tryptophan derivative, is a potent viral invasion inhibitor. ASF-006 sodium shows potent antiviral activity against different SARS-CoV-2 Omicron variants but not against the ancestral SARS-CoV.2 strain (Wuhan-Hu-1). ASF-006 sodium competitively inhibits receptor-binding domain (RBD)-ACE2 binding via an allosteric mechanism. ASF-006 sodium inhibits Omicron BA.1, Omicron XBB.1.5, respiratory syncytial virus (RSV) and Ebola virus infection with IC50s of 0.02 μM, 0.3 μM, 1.52 μM and 0.2 μM, respectively. ASF-006 sodium inhibits cell entry of both HIV and enterovirus A71[1].

Leucocrystal violet (Standard) is the analytical standard of Leucocrystal violet (HY-D0233). This product is intended for research and analytical applications. Leucocrystal violet is a cationic triarylmethane dye. Leucocrystal violet generates a colored purple product in the presence of hydrogen peroxide and horseradish peroxidase, or when oxidized by periodate under the catalysis of horseradish peroxidase. Leucocrystal violet serves as a chromogenic reagent for the determination of submicrogram-level hydrogen peroxide, with no interference from tryptophan, persulfate or chromate. Leucocrystal violet reacts with blood to produce a purple/violet color in the presence of hydrogen peroxide; it forms a very weak fluorophore when acting with whole blood in an unbuffered solution, with a maximum absorption wavelength of 630 nm and a maximum fluorescence emission wavelength of 665 nm upon excitation at 630 nm. Leucocrystal violet is widely used for staining blood residues on porous and non-porous materials.

Sennidin B Standard is the analytical standard of Sennidin B (HY-N6935). This product is intended for research and analytical applications. Sennidin B is an anthraquinone compound isolated from Cassia angustifolia. Sennidin B is a DPP-4 inhibitor with an IC50 of 39.39 μM. Sennidin B is an insect chitinase inhibitor with a Ki of 80 nM against OfChi-h. Sennidin B competitively inhibits chitinase activity by forming π-π stacking interactions with key tryptophan residues in the active site through a folded conformation. Sennidin B activates PI3K/Akt to promote glucose uptake in adipocytes. Sennidin B can be used for the development of biopesticides and research on type 2 diabetes and metabolism-related signaling pathways .

Synonyms: MEHHP-d4
Mono(2-ethyl-5-hydroxyhexyl) phthalate-d4 (MEHHP-d4) is a deuterium labeled Mono(2-ethyl-5-hydroxyhexyl) phthalate (HY-133677). Mono (2-ethyl-5-hydroxyhexyl) phthalate is a biomarker for human exposure to DEHP (HY-B1945). By activating the tryptophan-kynurenine-aryl hydrocarbon receptor (AhR) pathway, mono (2-ethyl-5-hydroxyhexyl) phthalate significantly increases the viability of primary uterine leiomyoma cells and reduces cell apoptosis. Mono (2-ethyl-5-hydroxyhexyl) phthalate correlates with decreased sperm DNA damage. Mono (2-ethyl-5-hydroxyhexyl) phthalate can be used in studies related to uterine leiomyoma.

Glutaric acid (Standard) is the analytical standard of Glutaric acid. This product is intended for research and analytical applications. Glutaric acid, C5 dicarboxylic acid, is an intermediate during the catabolic pathways of lysine and tryptophan. Glutaric acid affects pericyte contractility and migration. Glutaric acid is an indicator of glutaric aciduria type I . In Vitro: Glutaric acid (GA) at concentrations of 1 and 2 mM is able to reduce TRAP measurement by up to 28% in a dose-dependent manner (β=0.77; P<0.001). Furthermore, a significantly inverse correlation is also verified between chemiluminescence and TRAP (β=0.81; P<0.001). Glutaric acid does not alter the activities of Cat and SOD, but strongly inhibits (up to 46%) the activity of GPx even at the lower concentration used (0.5 mM). It is observed that the metabolite inhibits this activity in a dose-dependent manner at concentrations as low as 0.05 mM .

Triphenyl phosphate is an orally active, blood-brain barrier-permeable aryl organophosphate flame retardant and endocrine disruptor. Triphenyl phosphate disrupts mitochondrial dynamic balance through oxidative stress, induces excessive mitophagy and apoptosis, and ultimately leads to myocardial fibrosis. In the brain, Triphenyl phosphate activates the NF-κB inflammatory pathway by disrupting the gut microbiota, alters tryptophan metabolism and elevates neurotoxins, thereby inducing anxiety- and depression-like behaviors. In the skeletal and reproductive systems, Triphenyl phosphate inhibits osteoblast differentiation and induces germ cell apoptosis by suppressing the MAPK/ERK pathway and activating the JNK signal, respectively. In adipose and placental tissues, Triphenyl phosphate promotes lipid accumulation by activating the PI3K/AKT-PPARγ axis, and disrupts placental metabolism via the MAOA/ROS/NF-κB cascade, impairing neurodevelopment of offspring .

Nerve Growth Factor 2.5S,murine submaxillary gland is a neurotrophic polypeptide and protein growth factor isolated from murine submaxillary glands. Nerve Growth Factor 2.5S,murine submaxillary gland increases the survival rate, phagocytic capacity and superoxide anion production level of mouse cells. Nerve Growth Factor 2.5S,murine submaxillary gland acts through cell membrane surface receptors to mediate the differentiation and maintenance of adrenergic neurons in the sympathetic nervous system. Nerve Growth Factor 2.5S,murine submaxillary gland loses its activity and undergoes dimer dissociation due to oxidation; it remains active after modification of specific tryptophan residues, while its tyrosine residues are not essential for activity. Nerve Growth Factor 2.5S,murine submaxillary gland may play a role in the inflammatory process .
