closed-HMRG is an HMRG (HY-D2379) with a closed spiro-ring structure. HMRG is a fluorescent dye, which serves as the fluorescent active product generated by enzyme-activated fluorescent probes targeting proteases and glycosidases. Its detection mechanism relies on the intramolecular spirocyclization equilibrium: HMRG itself exists in an open non-spirocyclic structure under physiological pH, which maintains a conjugated π system and produces strong fluorescence; whereas its probe precursors (such as Leu-HMRG, Ac-GlyPro-HMRG and βGal-HMRG) exist in a closed spirocyclic form and show no fluorescence due to the disruption of the π-conjugated system; when the target enzyme cleaves the substrate fragment linked to the probe precursor, the closed spirocyclic structure converts to the open structure of HMRG, restoring the conjugated system and generating a strong fluorescent signal. Its detection wavelength is Ex/Em = 501/524 nm .

Tolterodine (tartrate) (Standard) is the analytical standard of Tolterodine tartrate. This product is intended for research and analytical applications. Tolterodine ((R)-(+)-Tolterodine) is a mAChR inhibitor and substrate for cytochrome P450 enzymes. Tolterodine competitively binds acetylcholine, reduces sympathetic excitation, and inhibits involuntary bladder muscle contraction. Tolterodine restores the Nrf2/NF-κB signaling pathway, mediates protection against inflammatory response and ferroptosis. Tolterodine ameliorates LPS (HY-D1056)-induced reactive oxygen species production and lipid oxidation. Tolterodine can be used for the research of urinary tract infections and overactive bladder.

2,2-Bis(p-hydroxyphenyl)-1,1,1-trichloroethane-d8 is the deuterated-labeled HPTE (HY-W490804). HPTE is the active in vivo metabolite of Methoxychlor (HY-B1873), and acts as an inhibitor of 3β‑HSD and 17β‑HSD3. HPTE binds to the substrate-binding pocket of 3β‑HSD in a non-competitive manner, but competitively occupies the coenzyme NAD +-binding site, thereby inhibiting the conversion of pregnenolone to progesterone. HPTE binds to the androstenedione-binding pocket (the substrate pocket) of 17β‑HSD3 in a non-competitive manner, and competitively occupies the coenzyme NADPH-binding site, thus blocking the conversion of androstenedione to testosterone. HPTE interferes with androgen biosynthesis in Leydig cells by inhibiting the activities of these two key steroidogenic enzymes. HPTE can be used in studies related to androgen biosynthesis .

Menaquinone 9 is a naphthoquinone-type vitamin K and electron transport component produced by bacteria. Menaquinone 9 is an orally active analog of Vitamin K2 (HY-109569). Menaquinone 9 acts as an ultraviolet-sensitive, photooxidizable substrate that generates more polar photodegradation products under oxygen and ultraviolet irradiation. Menaquinone 9 binds to the αβ dimer of Escherichia coli nitrate reductase, supporting electron transport within the αβ subunit structure of the enzyme. Menaquinone 9 serves as a precursor for bone Menaquinone-4 (HY-B2156). Menaquinone 9 can be used in studies related to metabolic diseases .

Glucoamylase, Rhizopus sp. (Amyloglucosidase, Rhizopus sp.) is a starch-hydrolyzing enzyme with high catalytic efficiency towards soluble starch and raw starch. Glucoamylase, Rhizopus sp. hydrolyzes α-1,4 and α-1,6 glycosidic linkages in starch and similar substrates, and primarily releases β-glucose molecules from the non-reducing ends. Glucoamylase, Rhizopus sp. participates in glycogen metabolism and is associated with type II glycogen storage disease. Glucoamylase, Rhizopus sp. converts starch into glucose, and is applicable to the industrial production of high-fructose syrup, ethanol and other fermented products .

Research Areas:
2'-Deoxytubercidin 5'-triphosphate (C7dATP) is a deoxyadenosine triphosphate (dATP) analog that serves as a substrate for DNA polymerases. 2'-Deoxytubercidin 5'-triphosphate eliminates Hoogsteen base-pairing capacity and weakens base-stacking interactions; it is recognized and incorporated into nascent DNA strands by DNA polymerases such as Klenow and T7; it reduces DNA electrophoresis compression artifacts; it is effectively degraded by apyrase, thereby lowering the enzyme product inhibition effect caused by dATPaS. 2'-Deoxytubercidin 5'-triphosphate reduces abnormal electrophoretic mobility caused by compression of G or A residues and is used to improve the quality of DNA sequencing data .

Thioetheramide-PC (1-Palmitylthio-2-palmitoylamido-1,2-dideoxy-sn-glycero-3-phosphorylcholine) is a structurally modified phospholipid that acts as a competitive, reversible inhibitor of secretory phospholipase A2 (sPLA2). Thioetheramide-PC has an IC50 value of 2 μM at a substrate concentration of 0.5 mM. In addition to binding to the catalytic site of sPLA2, Thioetheramide-PC also binds to the activation site of the enzyme. Thioetheramide-PC binds more tightly to the activation site than to the catalytic site. As a result of this dual interaction, at low concentrations, Thioetheramide-PC may activate phospholipase activity rather than inhibit it.
Cat. No.: HY-D3442
CAS No.: 3121565-89-4
Research Areas:
ALDH2 probe 5 is a ALDH2 isoform-selective fluorescent probe with an emission wavelength centered at 494 nm. ALDH2 probe 5 is a turn-on fluorescent substrate for ALDH2; in its unreacted aldehyde form, twisted intramolecular charge transfer (TICT) occurs, resulting in fluorescence quenching. After ALDH2 probe 5 is catalytically oxidized to carboxylate by ALDH2, TICT is inhibited and fluorescence is significantly enhanced. ALDH2 probe 5 enables highly sensitive quantitative imaging of ALDH2 activity in recombinant enzymes, live cells, blood, tissue homogenates, and the brains of living mice. ALDH2 probe 5 can be used for studies related to neuroinflammation .
