HS-CyBz is a Fluorescent probe for H₂S detection, enabling ratiometric optical/photoacoustic dual-modality in/ex vivo imaging. Its detection mechanism relies on nucleophilic substitution of its benzoic ester group by HS⁻, which releases an enolic meso-hydroxyltricarboheptamethine cyanine that then undergoes keto-enol tautomerization to form Cy-ketone; this tautomerization causes distinct shifts in absorption and emission spectra, producing a ratiometric response that reduces interferences from tissue scattering, autofluorescence, and probe concentration. In its initial state, HS-CyBz has an excitation wavelength of 595 nm, with emission bands centered at 805 nm (main) and 630 nm (minor); upon reaction with H₂S, the 805 nm emission band decreases while the 630 nm band drastically increases, and its absorption spectrum shows a sharp band at 775 nm and a shoulder band at 708 nm, which decrease upon H₂S reaction with a minor increase at 850 nm and an isosbestic point at 825 nm. For in vivo optical imaging, excitation at 560 nm is used with emission channels at 620 nm and 790 nm, while in vivo photoacoustic imaging uses excitation at 775 nm and 825 nm. The detection limit of HS-CyBz for H₂S is 0.5 μM, and it shows high selectivity, with only H₂S inducing a distinct enhancement of the emission ratio F₆₃₀/F₈₀₅ and PA ratio PA₈₂₅/PA₇₇₅, while other biochemical species including cations, anions, reactive oxygen species, biothiols, and carboxylesterase trigger only minor changes and do not interfere with H₂S sensing. Tail intravenous injection of HS-CyBz leads to accumulation in the liver of mice, and it can be used to verify endogenous H₂S upregulation triggered by S-adenosyl-L-methionine via ratiometric optical/photoacoustic imaging .

Cat. No.: HY-184607
Nanoclusters are essentially ultrasmall nanomaterials, typically with diameters between 1 and 10 nm, composed of a specific number of metal atoms (approximately 10 to several hundred) and ligands. This structure places their size between that of small molecules and traditional nanoparticles, exhibiting quantum effects. When the size of the metal core approaches the Fermi wavelength of electrons, its band structure transitions from a continuous state to discrete energy levels, thus exhibiting molecular-like properties such as single-electron transitions, multiple absorption bands, and strong photoluminescence. Iron nanoclusters (FeNCs) are a class of ultrasmall fluorescent nanomaterials composed of several to tens of iron atoms. Synthesized using bovine serum albumin (BSA) as a template and protectant via a chemical reduction method, these materials possess excellent optical properties and biocompatibility. Furthermore, they can be functionalized through surface modification, leading to their wide application in fields such as bioanalysis, environmental monitoring, and disease diagnosis.

Cefuroxime axetil is an orally effective broad-spectrum β-lactam antibiotic that targets bacterial penicillin-binding proteins (PBPs, such as PBP3 and PBP1). Cefuroxime axetil inhibits cell wall synthesis, leading to bacterial lysis and death, with a minimum inhibitory concentration (MIC) of 0.12-4 mg/L for non-typeable Haemophilus influenzae (NTHi). Cefuroxime axetil is hydrolyzed by esterase to the active ingredient Cefuroxime (HY-B1256A) after oral absorption. Topical administration of Cefuroxime via bioadhesive nanoparticles (BNPs) can prolong the drug's retention time in the middle ear (≥7 days). Cefuroxime axetil can be used in the study of otitis media (especially NTHi infection). Cefuroxime axetil can achieve precise antibacterial effects through oral or topical nano-delivery systems, reducing systemic exposure and the risk of antibiotic resistance .

TPE-2E N-oxide is a fluorescent probe used for hypoxia detection and tumor hypoxia imaging. Due to its active intramolecular motion, TPE-2E N-oxide shows no fluorescence in aqueous solution. In hypoxic environments, its N-oxide group undergoes two-electron reduction by CYP450 reductase and other heme protein reductases expressed under hypoxia, forming hydrophobic aggregates that trigger aggregation-induced emission through the restriction of intramolecular motion. TPE-2E N-oxide exhibits selective lipid droplet localization in cells. The absorption wavelength of TPE-2E N-oxide in dichloromethane is 313 nm; in a 99% hexane/dichloromethane mixed system, its excitation wavelength is 330 nm and emission wavelength is 460 nm. For in vitro cell imaging, excitation is performed at 405 nm, with an emission wavelength range of 430-560 nm .

CR-1 is a ratiometric photoacoustic (PA) probe for in-situ real-time imaging of Zn 2+ in deep living tissues. CR-1 is formed by coupling the near-infrared cyanine dye IR825 with the Zn 2+ ligand tris (2-pyridylmethyl) amine (TMPA). Upon binding to Zn 2+, the five N atoms on TMPA coordinate with Zn 2+, leading to double bond rearrangement of IR825 and attenuation of its π-electron conjugated system. The absorption peak of CR-1 blue-shifts from 710 nm to 532 nm, enabling quantitative detection of Zn 2+ via the PA532/PA710 ratio. Free CR-1 generates a strong PA signal at 710 nm, while CR-1 bound to Zn 2+ produces a strong PA signal at 532 nm .

Targeted protein degradation(TPD) is a novel and promising approach to new drug discovery and development. It shows great potential for treating diseases with “undruggable” pathogenic protein targets and for overcoming drug resistance. Molecular glues and PROTACs are both targeted protein degraders that have attracted the most attention.

Molecular glues are small molecular degraders that mainly induce novel interaction between an E3 ligase and a target protein to form a ternary complex, leading to protein ubiquitination and subsequent proteasome degradation. Compared with PROTACs, molecular glues generally possess more favorable drug-like properties, such as lower MW, higher cell permeability, and better oral absorption. Molecular glues are emerging as a promising new therapeutic strategy.

MCE supplies a unique collection of 124 molecular glues which target various proteins. MCE Molecular Glue Compound Library is a useful tool to conduct scientific research and disease mechanism study.

ZXX2-77 is a cyclooxygenase-1 (COX-1) selective inhibitor belonging to the benzenesulfonylanilide class of compounds. It is reported as a novel analgesic that does not cause gastric damage. ZXX2-77 has a weak analgesic effect but exhibits potent COX-1 inhibitory activity in vitro. The low oral absorption rate of ZXX2-77 leads to its weak analgesic effect in vivo. At a dose of 30 mg/kg, the maximum plasma concentration of ZXX2-77 (1.2 mM) did not reach its COX-1 IC50 value (3.2 mM). In contrast, its derivative ZXX2-79, although weaker in vitro COX inhibitory activity, is better absorbed, exhibits stronger analgesic effect and hardly causes gastric damage. These findings suggest that ZXX2-77 and its derivatives as COX-1 selective inhibitors may become effective analgesics that do not cause gastric damage.

Lys(CO-C3-p-I-Ph)-OMe is a pharmacokinetic modifier (PK modifier) that can improve the PK properties of PSMA ligand molecules (such as Ac-PSMA-trillium). Lys(CO-C3-p-I-Ph)-OMe can increase the residence time of Ac-PSMA-trillium in plasma by increasing its binding capacity to albumin. Lys(CO-C3-p-I-Ph)-OMe also reduces salivary gland absorption of Ac-PSMA-trillium, potentially extending its half-life. Ac-PSMA-trillium is a suitable PSMA-targeting compound that has different biological applications after modification with different radioactive isotopes. If labeled with 111In, it can be used as DOTA chelating agent and imaging agent. Or labeled with 225Ac as a Macropa chelator for targeted radionuclide therapy (TRT) in the study of metastatic castration-resistant prostate cancer (mCRPC) .
