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.

3β-hydroxy-5-Cholestenoic Acid is one of the metabolites of cholesterol found in high concentrations (40-80 ng ml) in human circulation.

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.

Synthetic and natural alkyl phosphates, also known as phosphoantigens, stimulate the proliferation of γδ-T lymphocytes. Isopentenyl pyrophosphate, and related derivatives including (E)-hydroxy-dimethyl-allyl pyrophosphate ((E)-HDMAPP), are particularly effective activators of γδ-T cells. (E)-C-HDMAPP is the pyrophosphonate form of (E)-HDMAPP. The pyrophosphonate moiety in (E)-C-HDMAPP is much less susceptible to chemical or enzymatic hydrolysis than its pyrophosphate counterpart. As a result, (E)-C-HDMAPP is much more stable in solution and in vascular circulation. (E)-C-HDMAPP possesses comparable activity to (E)-HDMAPP, which is the most potent of the isoprenoid phosphoantigens. (E)-C-HDMAPP stimulates the synthesis of tumor necrosis factor (TNF-α) by γδ-T lymphocytes with an IC50 value of 0.91 nM. (E)-C-HDMAPP also significantly increases the number of circulating γδ-T cells in vivo, in cynomolgus monkeys.

It is utilized in the conjugation process between the antibody and the cytotoxic drug, enabling the targeted delivery of the drug to cancer cells. The (2-pyridyldithio) group of this linker provides stability during circulation in the bloodstream, while the hydrazine moiety allows for efficient drug release at the tumor site. Overall, the (2-pyridyldithio)-PEG1-hydrazine linker serves as a valuable tool in the development of targeted chemotherapeutic agents for cancer treatment.
