Cat. No.: HY-D0041
CAS No.: 148504-34-1
Synonyms: Calcein acetoxymethyl ester
Calcein AM, has cell membrane permeability and can easily enter the cell. Calcein AM has no fluorescence and is hydrolyzed by endogenous esterase in the cell to produce polar molecule Calcein (Calcein), which has strong negative charge and cannot permeate the cell membrane. Calcein can emit strong green fluorescence, so it is often used with Propidium Iodide for cell viability/virulence detection, excitation/emission wavelength: 494/515 nm .

Thiazole Orange is an asymmetric anthocyanin dye that can be coupled with oligonucleotides (ONs) to prepare fluorescent hybridization probes. Thiazole Orange has been widely used in biomolecular detection and staining of DNA/ RNA in gels and can be used for reticulocyte analysis. Thiazole orange generates a significant fluorescence enhancement and high quantum yield when it binds with nucleic acids, especially RNA. Thiazole orange can permeate living cell membranes. Thiazole orange can use UV light for detection, but can also be detected with blue light. The excitation and emission of Thiazole orange are λex = 510 nm (488 nm and 470 nm also show strong excitation) and λem = 527 nm, respectively .

Synonyms: Dextran 3; Dextran D3; Dextran T3(MW 2400-3600)
Dextran T3 (Dextran 3; Dextran T3(MW 2400-3600)) is a neural tracer and intestinal permeability probe that can move anterogradely and retrogradely in neuronal axons by passive diffusion. Dextran T3 (MW 3,000) is able to permeate across the intestinal epithelial cell membrane in the presence of cholera toxin-induced cytoskeletal disturbance. Dextran T3 (MW 3,000) is used as a fluorescent marker to rapidly label developing neurons (such as Xenopus retinal ganglion cells) and to assess intestinal barrier function. It can be used to study axonal transport in neuroanatomy and permeability changes in intestinal pathophysiology. The Dextran series of compounds are also natural polysaccharide drug carriers that can be connected to drugs through covalent bonding methods such as ester bonds, amide bonds or click chemistry, or self-assembled to form carriers such as nanoparticles and hydrogels. Dextran is biodegradable and biocompatible, and can achieve targeted delivery and controlled release of drugs. Dextran derivatives can prolong the half-life of drugs, increase local concentrations, and reduce the activity of immune clearance .

N-Acetyl-L-tyrosine is an orally active endogenous mitochondrial stress response regulator that can permeate the cell membrane by passive diffusion. N-Acetyl-L-tyrosine induces low-level reactive oxygen species (ROS) generation by transiently perturbing mitochondrial membrane potential, triggering reverse signaling to activate FoxO and Keap1 pathways. As a result, N-Acetyl-L-tyrosine enhances the expression of antioxidant enzyme genes, exerting anti-stress and cytoprotective effects. N-Acetyl-L-tyrosine can improve heat stress tolerance, inhibit tumor growth, and regulate energy metabolism. N-Acetyl-L-tyrosine can be used in the research of aging, metabolic diseases (such as diabetes), and cancer .

Infection

2A3 (2-aminopyridine-3-carboxylic acid imidazolide) is a covalent probe reagent for Selective 2'-Hydroxyl Acylation analyzed by Primer Extension (SHAPE) that targets the RNA ribose 2'-OH group. 2A3 efficiently permeates the biological membranes of Gram-negative bacteria, Gram-positive bacteria, and mammalian cells. 2A3 exhibits no base bias and specifically labels conformationally flexible, unpaired regions within RNA. 2A3 forms covalent adducts by acylating the 2'-OH groups of flexible RNA residues. When combined with SHAPE-MaP (mutational profiling) sequencing technology, these modification sites are converted into detectable mutational signals, thereby accurately reflecting local RNA backbone flexibility and base-pairing status. 2A3 is primarily utilized in molecular biology and transcriptomics research, including the resolution of RNA structuromes in living cells, the study of RNA folding regulatory mechanisms, and the investigation of non-coding RNA functions .

Viruses are much simpler organisms than bacteria, and they are made from protein substances and nucleic acid. Despite the fact that the exact mechanism of infection is extremely specific to each type of virus, the general scheme of infection can be represented in the following manner: A virus is absorbed at the surface of a host cell and then permeates through the membrane, where it releases nucleic acid from its protein protection. Then the viral nucleic acid begins to replicate, and transcription of the viral genome takes place either in the cytoplasm, or in the nucleus of the host cell. As a result of these events, a large amount of viral nucleic acid and protein are made to make new generations of virions. Therefore, one mechanism of action of antiviral drugs is to interfere with the ability of a virus to get into a target cell. A second mechanism of action is to target the processes that synthesize virus components after a virus invades a cell, such as nucleotide or nucleoside analogs.

MCE designs a unique collection of 1,237 anti-virus compounds that target several viruses, including SARS-CoV, HBV, HCV, HIV, HSV and Influenza Virus. It’s an effective tool for anti-virus drug discovery.
