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.

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.

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.

(R,S)-Anatabine is a minor tobacco alkaloid found in the Solanaceae family of plants, and serves as a specific marker for detecting tobacco use.

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.

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.

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.

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.

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.

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.

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.

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.

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.

KS370G (Caffeic Acid Phenethyl Amide) inhibits UUO-induced renal fibrosis marker expression. KS370G is an orally active hypoglycemic and cardioprotective agent that reduces collagen deposition in obstructed kidneys and significantly decreases renal expression of inflammatory chemokines adhesion molecules and monocyte markers and improves left ventricular hypertrophy and function in the heart of pressure-overloaded mice.KS370G can be used to study renal obstructive nephropathy.

L-Alloisoleucine (L-allo-Isoleucine) is a branched chain amino acid and is a stereoisomer of L-isoleucine. It is a common constituent of human plasma (albeit at low levels). L-alloisoleucine is produced as a byproduct of isoleucine transamination. Plasma L-alloisoleucine, which is derived from L-isoleucine in vivo, can be used for the diagnosis of maple syrup urine disease (MSUD), a genetic disorder. Indeed, plasma L-alloisoleucine levels above 5 μmol L is the most specific and most sensitive diagnostic marker for all forms of MSUD.

Meconin, a noscapine metabolite, is a urinary detection marker for illicit opiate misuse. This product is intended for use as a forensic standard.

C-Reactive Protein (CRP) 201-206 acetate (C-Reactive Protein ) is the 201-206 fragment of C-Reactive Protein. C-Reactive Protein (CRP) acetate, the prototypic marker of inflammation, is a cardiovascular risk marker and may promote atherogenesis.

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

C17 Ceramide is a synthetic ceramide that contains a non-natural C17:0 fatty acid acylated to sphingosine. It has been used as a marker of arylsulfatase A and sphingolipid activator B activity in patients undergoing enzyme replacement therapy for the genetic disease metachromatic leukodystrophy.
