Acridine Orange hydrochloride is a cell-permeable fluorescent nucleic acid dye and lysosomal probe with a pKa of 9.65. Acridine Orange hydrochloride enters cells via passive diffusion, is protonated and accumulates in acidic lysosomes, and forms aggregates at high concentrations, producing orange-red fluorescence; when the lysosomal proton gradient or membrane integrity is impaired, Acridine Orange hydrochloride is released into the cytoplasm, green fluorescence increases and red fluorescence decreases, so it can be used to monitor lysosomal acidification status and changes in membrane permeability. Acridine Orange hydrochloride binds to nucleic acids through intercalation or electrostatic interactions, exhibiting mainly green fluorescence when bound to double-stranded DNA and mainly red fluorescence when bound to RNA or single-stranded DNA, and can be used for nucleic acid staining and differential DNA/RNA detection. The Ex/Em of Acridine Orange hydrochloride monomer is approximately 492/525 nm; when bound to double-stranded DNA it is approximately 488/520-524 nm, and when bound to RNA or single-stranded DNA it is approximately 457/630-650 nm .

Synonyms: MK-208
Famotidine (MK-208) is an orally active and highly selective histamine H2 receptor antagonist. It inhibits gastric acid secretion by blocking the Gs signaling pathway, and regulates intracellular cAMP and ERK pathways. Famotidine inhibits TLR3-mediated inflammatory pathways, and reduces the expression of various inflammatory mediators and interferon-related genes. Famotidine scavenges DPPH and nitric oxide free radicals, alleviates oxidative stress damage in gastric tissue, inhibits proMMP-9, improves vascular endothelial permeability, and restores the normal physiological functions of neutrophils and eosinophils. Famotidine crosses intestinal epithelial cells via facilitated diffusion and passive diffusion, blocks paracellular cation transport, and increases intestinal transepithelial electrical resistance. Famotidine reduces serum levels of transaminases and alkaline phosphatase, exerts analgesic effects and gastric protective effects simultaneously. Famotidine can be used in studies related to COVID-19, liver injury and acute gastric ulcer .

Synonyms: Gly-Gly; H-Gly-Gly-OH
Glycylglycine is a non-selective glycylglycine dipeptidase substrate and iNOS inhibitor. Glycylglycine can cross the cell membrane by passive diffusion and is hydrolyzed to glycine in the cell, participating in energy metabolism and antioxidant processes. Glycylglycine promotes spermatogonial stem cells (SSCs) proliferation, inhibits astrocyte overactivation and reduces nitric oxide (NO) release, while upregulating the expression of neurotrophic factors (such as PDGFA, FGF2, CNTF) to support nerve myelin repair. Glycylglycine can be used to study male reproductive biology (such as SSCs proliferation regulation) and neurodegenerative diseases (such as neuroprotective mechanisms in multiple sclerosis) .

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 .

trans-Cyclohexane-1,2-diol (TCHD) is a transient dilator of the nuclear pore complex (NPC). By interacting with the hydrophobic core (FG nucleoporin) of the NPC, trans-Cyclohexane-1,2-diol can disrupt the NPC structure and reversibly increase the permeability of the nuclear pore, allowing macromolecules larger than 40 kDa (such as plasmid DNA) to enter the cell nucleus by passive diffusion, thereby enhancing the nuclear import efficiency of non-viral vectors. trans-Cyclohexane-1,2-diol can improve the efficiency of in vitro electrotransfection or lipid-mediated gene transfection, especially significantly increasing gene expression in differentiated airway epithelial cells .
