Zinc Protoporphyrin (Zn(II)-protoporphyrin IX) is an orally active, competitive inhibitor of heme oxygenase-1 (HO-1) that markedly attenuates the protective effects of Phloroglucinol (PG) against H2O2 and exhibits anti-cancer activity.

AT-121 is a dual μ-opioid and neuropeptide receptor partial agonist (Kis 16.49 and 3.67 nM, respectively). It stimulates [35S]GTPγS binding to cell membranes expressing either μ-opioid receptors or neuropeptide receptors (EC50s of 19.6 and 34.7 nM, respectively.) AT-121 (0.003-0.03 mg kg) reduced capsaicin-induced thermal anisocoria in a dose-dependent manner, but did not increase scratching activity in rhesus monkeys. In rhesus monkey drug self-administration tests, AT-121 at doses of 0.3 to 10 μg kg per injection lacked reinforcing effects (a potential marker of abuse) and did not reduce the reinforcing effects of food pellets.AT-121 (0.01 or 0.03 mg kg) did not induce hyperalgesia, a marker of tolerance, in rhesus monkeys.AT-121 is a safe non-addictive pain reliever with anti-injury and analgesic effects.

DIPQUO hydrochloride is an activator of the bone marker alkaline phosphatase (ALP), with an EC50 of 6.27 μM in C2C12 cells. DIPQUO hydrochloride promotes mouse and human osteoblast differentiation via activation of p38 MAPK-β.

Muramic acid is a prevalent constituent found in the cell walls of Gram-positive bacteria, serving as a distinguishing marker for such bacteria[1].

3-Carene(Delta-3-Carene) is a bicyclic monoterpene extracted from western larch and Douglas-fir that acts as a phytofungicide.3-Carene inhibits inflammatory infiltrates and COX-2 overexpression induced by nociceptive stimuli.3-Carene has anti-injury properties and promotes the activity and expression of alkaline phosphatase, an early marker of osteoblast differentiation.

5-Bromouridine is a uracil derivative with a broad spectrum of antitumor activity that induces apoptosis in cancer cells by inhibiting DNA synthesis.5-Bromouridine is also used as a marker for DNA and RNA, where the molecule is labeled with a radioisotope or pigment after being introduced into a DNA or RNA strand.

Glycocyamine (2-Guanidinoacetic acid), a precursor of creatine, is a replacement of dietary arginine and could support overall energy homeostasis of the bird. Glycocyamine is an important marker for renal failure, kidney transplantation, and the renal metabolic activity. The compound is a metabolite of guanidine.

2'-Deoxyguanosine monohydrate (Guanine-2'-deoxyriboside) is a nucleoside consisting of the base guanine and the sugar deoxyribose. It is like guanosine, but with one oxygen atom removed. It is a nucleoside component of DNA. 2'-Deoxyguanosine monohydrate can be converted to 8-hydroxy-deoxyguanosine (8-OHdG) due to hydroxyl radical attack at the C8 of guanine. 8-OHdG is a sensitive marker of the DNA damage This damage, if left unrepaired, has been proposed to contribute to mutagenicity and cancer promotion.

Heptadecanoic acid is a fatty acid of exogenous (primarily ruminant) origin. Many odd length long chain amino acids are derived from the consumption of dairy fats (milk and meat). Heptadecanoic acid constitutes 0.61% of milk fat and 0.83% of ruminant me

N-(5-Aminopentyl)acetamide (N-Acetylcadaverine) is the acetylated form of the polyamine cadaverine. Cadaverine is produced by the breakdown of amino acids in living and dead organisms and is toxic in large doses. N-(5-Aminopentyl)acetamide is a promising biochemical marker for cancer and many other pathophysiological conditions.

Tridecanedioic acid (Brassilic acid) is an unusual odd-numbered dicarboxylic acid that appears in the urines of children with neonatal adrenoleukodystrophy and Zellweger syndrome, as an additional marker of these peroxisomal disorders.

3-Chloro-L-Tyrosine (Chlorotyrosine), a specific marker of myeloperoxidase-catalyzed oxidation, is markedly elevated in low-density lipoprotein isolated from human atherosclerotic intima. In particular, myeloperoxidase halogenates tyrosine residues in plasma proteins and generates 3-chlorotyrosine (CY). The detection of free chlorotyrosine in blood or urine arises from the degradation of these chlorinated proteins. CY concentrations may be useful for monitoring the activation of neutrophils in asthmatic patients.

4-tert-Octylphenol, an endocrine-disrupting chemical with estrogenic properties, notably induces apoptosis in offspring mouse brain neuronal progenitor cells. This compound decreases levels of bromodeoxyuridine (BrdU), mitotic marker Ki67, and phospho-histone H3 (p-Histone-H3), thereby diminishing the proliferation of neuronal progenitors. Consequently, 4-tert-Octylphenol adversely affects brain development and behavior in mice.

3,5-Dimethoxyphenol (Phloroglucinol dimethyl ether) as a marker of Taxus poisoning, being present in all species of Taxus. It has potent tyrosinase-inhibiting activity.

Fibrinogen is a heterodimeric protein that can be cleaved by thrombin. Fibrinogen is a potential marker for cardiovascular disease and plays an important role in metabolism. Its absence can cause fibrinogenemia.

8-Amino-1-Naphthalenesulfonic Acid is a naphthalene derivative used as a fluorescent dye and as a reagent in organic synthesis. It is a highly fluorescent compound with a high Stokes shift, making it an ideal fluorescent marker for a wide range of biological systems.

Aniline-d5 is a deuterated isotope marker of Aniline, which can be used for isotope tracing.Aniline induces toxicity to the spleen through iron overload and oxidative stress via heme oxygenase 1 up-regulation and is able to lead to a significant increase in p-IKKα and p-IKKβ, which in turn increases NF-κB and AP-1 binding activity.

4-Hydroxypyrrolidine-2-carboxylic acid (4-hydroxyproline) is a non-protein amino acid and endogenous metabolite present in collagen that modulates collagen elasticity and can be used as a diagnostic marker for bone conversion and liver fibrosis.

7-Methyladenine (NSC-7857) can be used as a marker of exposure to exogenous and carcinogenic methylating agents.
