YM 534 has antitumor activity and platelet aggregation activity, inhibits photoaffinity labeling of deglycosylated P-glycoprotein, and can be used to study leukemia.

Tetracycline hydrochloride (NCI-c55561) is the hydrochloride salt of the tetracycline, a broad-spectrum naphthacene antibiotic produced semisynthetically from chlortetracycline, an antibiotic isolated from the bacterium Streptomyces aureofaciens. In bacteria, tetracycline blocks binding of aminoacyl-tRNA to the mRNA-ribosome complex, thereby inhibiting protein synthesis and bacterial cell growth. Because naturally, fluorescing tetracycline binds to a newly formed bone at the bone/osteoid interface, tetracycline-labeling of bone and fluorescence microscopy may be used to perform bone histomorphometry.

Biotin (Vitamin H) is a water-soluble B-vitamin and is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids.

D-Desthiobiotin is a biotin derivative used in affinity chromatography and protein chromatography, as well as for protein and cell labeling, detection, and separation.

EDC hydrochloride (EDC-HCl Crosslinker) is a water-soluble carbodiimide compound. EDC hydrochloride, as a condensing agent, forms peptide bonds through the condensation reaction of carboxyl and amino groups and can be used to synthesize peptides with specific sequences and functions. EDC hydrochloride can covalently bind haptens to carrier proteins to form immune antigens, which are used in vaccine research. EDC hydrochloride can react with the 5 'phosphate group of nucleic acids and is used for the labeling of DNA and RNA. EDC hydrochloride can cross-link proteins with nucleic acids and is used to prepare immune cross-links. EDC hydrochloride, as a crosslinking agent, connects the amine-reactive NHS ester of biomolecules with the carboxyl group, which can be used for protein coupling to create hybrid molecules with new properties and functions.

Cyanoacetamide has inhibitory activity against the myeloid leukaemia cell differentiation protein Mcl-1 and is widely used in biochemical experiments and drug synthesis research.

Edaravone, a novel and potent free radical scavenger, effectively prevents MMP-9-related brain hemorrhage in rats treated with tissue plasminogen activator. Its deuterium-labeled variant, Edaravone D5, retains the original compound's attributes while offering isotopic labeling benefits.

Ethacrynic acid, a diuretic, functions as an inhibitor of L-type voltage-dependent and store-operated calcium channels, facilitating the relaxation of airway smooth muscle (ASM) cells. It exhibits anti-inflammatory effects, notably reducing retinoid-induced ear edema in mice, and inhibits glutathione S-transferases (GSTs), making it a potent suppressor of the NF-kB signaling pathway. Additionally, ethacrynic acid modulates leukotriene formation. A variant, Ethacrynic acid D5, is distinguished by its deuterium labeling.

FAPI-2 is a specific inhibitor of fibroblast-activated protein based on the radiotracer FAP labeling. It has anticancer activity and can be used in the study of pancreatic cancer.
