Biotin-11-UTP is a biotinylated uridine triphosphate that can be incorporated into short RNA strands via co-transcription with T7 RNA polymerase, and is used for synthesizing labeling reagents and detection markers. After binding to streptavidin, Biotin-11-UTP generates characteristic downward ionic current peaks during nanopore translocation, which allows the differentiation between modified and unmodified RNA. Biotin-11-UTP enables site-specific labeling of short RNA, and is suitable for single-molecule solid-state nanopore sensing detection. Biotin-11-UTP can serve as a raw material for synthesizing biotinylated single-stranded RNA probes, which is applied to rotavirus nucleic acid detection; it can also label single-stranded RNA probes targeting and immobilizing 28S ribosomal RNA in leukemia cells. Biotin-11-UTP can alter the electrophoretic mobility of transcribed RNA in agarose gels, and can be used to monitor the biotinylation degree of RNA probes .

DCA-Mln is a Fluorescent probe for ferric iron (Fe³⁺) detection. The probe works via an internal charge transfer (ICT) process from its diethylamino group to its dicyano group, which produces bright pink fluorescence in its unbound state; when Fe³⁺ is present, two molecules of DCA-Mln chelate with one Fe³⁺ ion, with one cyano group of each DCA-Mln participating in the complexation, and this binding triggers a photoinduced electron transfer (PET) process that provides a nonradiative deactivation pathway, resulting in fluorescence quenching; additionally, the probe exhibits a visible color change from purple to peach pink upon Fe³⁺ binding, enabling dual-channel detection. The probe has an excitation wavelength of 570 nm and an emission wavelength of 670 nm, and it shows a rapid response, with fluorescence stabilizing within 15 seconds of Fe³⁺ addition. DCA-Mln is cell-membrane-permeable, nontoxic at the imaging concentration of 10 μM, and can be used for Fe³⁺ detection in actual water samples, Fe³⁺ imaging in living cells, and as an anti-counterfeiting ink[1].

Boronic acid and boronic ester represent a relatively novel and promising chemical structure in drug design. Boronic acid exists in an sp²-hybridized state, possessing an empty p-orbital that can act as a Lewis acid to accept lone pairs from heteroatoms (O, N, or S). This Lewis acidity enables it to form reversible covalent bonds with amino acid residues such as lysine, serine, threonine, and histidine. Currently, five FDA-approved drugs containing boronic acid or boronic ester predominantly involve such covalent binding mechanisms in their interactions with target proteins. Furthermore, boronic acid can serve as a bioisostere for carboxylic acids, phosphates, and phenolic groups, utilized to improve pharmacokinetic properties and enhance drug efficacy.
To date, five boron-containing drugs have been approved by the FDA. The unique properties of boronic acids and boronic esters confer significant potential in drug design, with applications spanning cancer therapy (e.g., multiple myeloma), anti-infectives (e.g., fungal infections, tuberculosis), anti-inflammatory treatments (e.g., atopic dermatitis), antibacterial agents (e.g., carbapenem-resistant bacterial infections), and Reactive Oxygen Species (ROS)-responsive prodrugs, among others. The MCE Boronic Acid/Boronic Ester Fragment Library, which contains 1,488 compounds, serves as a valuable tool for the development of boron-containing drugs.

CAS No.: 486440-74-8
UE01 is an orally active, selective small-molecule modulator targeting both ULK1/ERK1/2. UE01 activates hULK1 with an EC50 of 695.30 nM and a KD of 114.3 nM for ULK1; it inhibits hERK1 with an IC50 of 179.90 nM and a KD of 114 nM for ERK1; it shows weak binding to ERK2 with a KD of 2.8 mM. UE01 induces the conformational transition of ULK1 from an inactive to an active state, enhances the phosphorylation of ULK1 Ser317 and mAtg13 Ser355, and reduces the phosphorylation of ULK1 Ser757. UE01 competitively occupies the ATP-binding pocket of ERK1, inhibits ERK1 kinase activity, and reduces the activity of the ERK1/2 signaling pathway. UE01 induces complete autophagy flux and apoptosis, upregulates Atg5, Atg7, LC3-II/LC3-I, Bax, cytochrome C (Cyt c), Cleaved-Caspase 3, Cleaved-PARP1 and E-cadherin, downregulates p62, Bcl-2, MMP-2 and MMP-9, reduces the phosphorylation of Exo70 Ser250, and promotes the proteasome-dependent degradation of Cav-1, thereby inhibiting EMT-related phenotypes and extracellular matrix degradation. UE01 can be used in studies related to triple-negative breast cancer .

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].

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 .
