(2-Pyridyldithio)-PEG4 acid is a four-unit cleavable polyethylene glycol (PEG) linker specifically designed for the synthesis of antibody-drug conjugates (ADCs)[1]. It serves as a crucial component in the conjugation of antibodies and drugs, enabling targeted drug delivery and enhanced therapeutic efficacy. This linker possesses a (2-pyridyldithio) group at one end, facilitating the attachment of the linker to the specific site on the antibody molecule. The PEG4 chain provides the necessary flexibility and biocompatibility for optimal drug release while maintaining stability throughout the circulation in the body. Ultimately, (2-Pyridyldithio)-PEG4 acid is instrumental in the development and advancement of ADCs, a promising approach in cancer therapy.

Anhydroleucovorin is the predominant, biologically active form of vitamin B9 (folate) that is utilized by the body for a multitude of vital cellular functions, including DNA synthesis, repair, and methylation, as well as the production of key neurotransmitters; Anhydroleucovorin plays an essential metabolic role in the remethylation pathway, converting the amino acid homocysteine to methionine, and serves as the main folate form found in systemic circulation and transported into tissues for physiological use.

DOTAGA-FAP-2286-ALB is a derivative of Rofapitide tetraxetan. It functions as a selective inhibitor of fibroblast activation protein (FAP) with an IC50 value of 67.5 nM. By interacting with albumin, DOTAGA-FAP-2286-ALB enhances tumor retention, prolongs circulation time in the bloodstream, and improves the stability of radiometal complexes [such as 111In and 225Ac]. This compound shows promise for use in targeted radionuclide therapy (TRT) research for FAP-positive solid tumors.

Dimephosphon is an anti-inflammatory agent exhibiting both antihistamine and antiserotonin activities. It aids in maintaining spinal cord conduction function and reduces the excitability of motor neurons around lesion areas. Additionally, Dimephosphon directly stimulates lymph vessel movement, enhancing lymph circulation.

Peroxidation of common ω-6 polyunsaturated fatty acids (PUFAs) such as linoleic acid, DGLA, and arachidonic acid can give rise to 4-HNE. 4-HNE is cleared rapidly from the plasma and undergoes enterohepatic circulation as a glutathione conjugate in the rat. About two thirds of an administered dose of 4-HNE is excreted within 48 hours in the urine, primarily in the form of mercapturic acid conjugates. The C-1 aldehyde of 4-HNE is reduced to an alcohol in about half of these metabolites. The remainder are C-1 aldehydes or have been oxidized to C-1 carboxylic acids. These aldehydes and carboxylic acids can also form γ-lactols and γ-lactones, respectively, producing at least 4 or 5 end urinary metabolites of 4-HNE in vivo.

Thromboxane B2 (TXB2) is released in substantial quantities from aggregating platelets and metabolized during circulation to 11-dehydro TXB2 and 2,3-dinor TXB2. In rats and rabbits, 2,3-dinor TXB1 has been identified as another urinary metabolite of TXB2. However in human urine, only trace amounts of 2,3-dinor TXB1 have been identified. In rats, 2,3-dinor TXB1 is excreted at a much higher rate than 2,3-dinor TXB2 (19.2 ± 4.9 ng/24 hr and 1.6 ± 0.3 ng/24 hr, respectively). Therefore, urinary 2,3-dinor TXB1 is a suitable marker of thromboxane biosynthesis in rats.
