Fluoresterol (22-NBD Cholesterol) is a cholesterol-specific fluorescent probe with cholesterol-mimicking binding properties. Fluoresterol is ineffective orally and does not cross the blood-brain barrier. Fluoresterol specifically binds to cholesterol transport-related proteins (such as ABCA1 and ABCG1) and is primarily used in cholesterol metabolism research, particularly for the visualization and quantitative analysis of cholesterol absorption, efflux, intracellular transport efficiency, and reverse cholesterol transport (RCT) processes. The commonly used concentration of Fluoresterol in in vitro experiments is 0.1-10 μM, and the commonly used dose in in vivo experiments is 5-20 mg/kg (gavage or intraperitoneal injection), with excitation/emission wavelengths of 472/540 nm. Fluoresterol can be applied to the study of cholesterol metabolism mechanisms related to hyperlipidemia, atherosclerosis, and non-alcoholic fatty liver disease (NAFLD) .

TASP0434299 (Compound 10) is a labeled ligand for the vasopressin V1b receptor. TASP0434299 exhibits high binding affinity for human and murine V1B receptors, with IC50 values of 0.526 nM and 0.641 nM, respectively, and shows potent antagonistic activity against the human V1B receptor with an IC50 of 0.639 nM. TASP0434299 is a substrate for human and rhesus monkey P-glycoprotein, resulting in low brain uptake in rhesus monkeys. TASP0434299 binds to V1B receptors in rat and monkey pituitary tissues in a saturable and specific manner both in vitro and in vivo. When radiolabeled with tritium or 11C, TASP0434299 serves as a prototype V1B receptor radiotracer to visualize V1B receptor in the pituitary gland of anesthetized monkeys via positron emission tomography .

Synonyms: SNAP-PEG-NH2
Target:
Research Areas:
BG-PEG-NH2 (SNAP-PEG-NH2) is an amino-terminal fluorescent probe building block and a precursor for site-specific labeling of SNAP-tag fusion proteins. BG-PEG-NH2 undergoes one-step coupling with activated carboxyl esters to form customized SNAP-tag substrates, which covalently bind to SNAP tags via a thioether bond formed at the Cys145 site. After coupling with a caged carboxyfluorescein, BG-PEG-NH2 forms a probe with Ex/Em = 500/524 nm following ultraviolet uncaging. Coupling of BG-PEG-NH2 with SeTau-647-NHS enables visualization of GPCR signal transduction. BG-PEG-NH2 is suitable for coupling reactions in aqueous phases or buffers, conjugation of labels, and labeling of intracellular or cell-surface proteins .

Research Areas:
Lys-VBOD is a Fluorescent probe for lysosomal viscosity monitoring and live cell imaging. Its detection mechanism depends on viscosity: increased viscosity restricts the twisting of the double bond between the indole and BODIPY fluorophore, as well as the rotation of the single bond between quinoline and BODIPY, which reduces non-radiative decay and leads to enhanced fluorescence intensity in high viscosity environments; it also features a morpholine group that provides lysosome-targeting properties, allowing it to localize to lysosomes for viscosity detection. The probe has excitation/emission wavelengths of Ex/Em = 602/637 nm, and its fluorescence intensity shows a good linear relationship with log-transformed viscosity values. Lys-VBOD is stable across a wide pH range of 5.35 to 10.74, is not affected by macromolecules and proteins like BSA, has a fluorescence lifetime that increases with viscosity, and can visualize real-time lysosomal viscosity changes in live cells under Dexamethasone (HY-14648) stimulation[1].

CS790AM (Coppersensor 790 acetoxymethyl ester) is a cell-permeable, Cu +-targeted near-infrared fluorescent probe (λabs=760 nm, λem=790 nm) applicable to live cells. CS790AM can cross lipophilic cell membranes, and is converted into negatively charged CS790 under the action of intracellular esterases to be retained, thus enabling highly sensitive, reversible "turn-on" detection of labile Cu + pools in live cells and mice. CS790AM possesses excellent biocompatibility and selectivity, avoids interference from other metal ions, shows no obvious toxicity, and can be rapidly cleared. CS790AM allows long-term longitudinal monitoring of individual mice, visualizes copper levels in internal organs and isolated livers, and effectively evaluates abnormal copper accumulation in Wilson's disease models (Atp7b -/-) as well as dynamic changes after chelator treatment. CS790AM can be used for research on Wilson's disease and related copper metabolic disorders .

Research Areas:
DCA is a Fluorescent probe for visualization of phase behavior in ER membranes. DCA is an ER-targeting, polarity-responsive NIR ratiometric probe, with its p-toluenesulfonamide group responsible for ER localization; its sensitivity to polarity relies on its donor-π-acceptor (D-π-A) structure, where aniline acts as the donor and dicyanomethylene acts as the acceptor, driving an intramolecular charge transfer (ICT) process upon excitation. In environments with low polarity, such as the closely packed, low water content ERₒ phase of ER membranes, DCA emits at a shorter wavelength, while in high polarity environments like the loosely packed, higher water content ERd phase, ICT leads to a red-shifted emission, allowing discrimination of the two phases via dual NIR emission colors and ratiometric imaging. Ex/Em = 488/570–620 nm and 488/665–735 nm; additional excitation/emission pairs include Ex/Em = 488/631 nm in low polarity 1,4-dioxane and Ex/Em = 488/677 nm in 1,4-dioxane with 30% water, the higher polarity condition. It shows a large Stokes shift of ~170 nm, and pH, viscosity, and biologically relevant species including Cys, GSH, H₂O₂, and metal ions do not exert marked interference on its fluorescence spectra[1].

Research Areas:
MBCB is a two-photon Fluorescent probe for dual-detection of mitochondrial SO₂ derivatives and viscosity. For SO₂ derivatives detection, the probe utilizes a Michael addition mechanism: nucleophilic addition of SO₂ derivatives to the C=C bond between the carbazole skeleton and 3-methylbenzothiazolium moiety destroys the strong intramolecular charge transfer (ICT) system between these groups, while enhancing the weak ICT system between the benzothiazole group and carbazole framework; this causes the red emission at 600 nm to decrease and the blue emission at 434 nm to increase, creating a ratiometric response based on the I₄₃₄ₙₘ/I₆₀₀ₙₘ intensity ratio. For viscosity detection, in low-viscosity environments, steric hindrance creates a twisted ICT (TICT) system with weak fluorescence, while in high-viscosity environments, intramolecular rotation is blocked, the TICT state is disrupted, and the strong ICT system is recovered, leading to a strong red emission at 567 nm with negligible change to the short-wavelength emission at 415 nm, creating a ratiometric response based on the I₅₆₇ₙₘ/I₄₁₅ₙₘ intensity ratio that has a logarithmic linear relationship with viscosity. The probe has excitation/emission wavelengths of Ex/Em = 351/434, 600 nm for SO₂ derivatives detection and Ex/Em = 351/567 nm for viscosity detection, with two-photon excitation at 740 nm for bioimaging; it also exhibits good mitochondrial targeting ability with a Pearson's colocalization coefficient of 0.93 when paired with Mito-Tracker Green. The probe shows high sensitivity and selectivity for SO₂ derivatives, has low cell cytotoxicity, and can be applied to detect exogenous/endogenous HSO₃⁻ in living cells and in vivo, as well as visualize mitochondrial viscosity changes induced by nystatin[1].
