Betamethasone Dipropionate is the 17, 21-dipropionate ester of betamethasone, a synthetic glucocorticoid with metabolic, immunosuppressive and anti-inflammatory actions. Betamethasone dipropionate (SCH 11460) binds to specific intracellular glucocorticoid receptors and subsequently binds to DNA to modify gene expression. The synthesis of certain anti-inflammatory proteins is induced while the synthesis of certain inflammatory mediators is inhibited. As a result, there is an overall reduction in chronic inflammation and autoimmune reactions.

(-)-Epicatechin gallate ((-)-Epicatechin 3-O-gallate) is one of the catechin isomers and a potent antioxidant that can modulate a wide range of membrane proteins. Its bilayer-modifying potency was tested using gramicidin A (gA) channels as probes. All the catechins alter gA channel function and modify bilayer properties, with a 500-fold range in potency. The gallate group causes current block, as evident by brief downward current transitions.

Cyfluthrin binds to voltage-sensitive sodium channel such as Nav 1.8 sodium channel and modify their gating kinetics, thereby disrupting nerve function of pests.

2,2-Dihydroxyacetic acid (Formylformic acid) is an intermediate in the glyoxalate cycle, which enables certain organisms to convert fatty acids to carbohydrates.2,2-Dihydroxyacetic acid has been found to be associated with primary hyperoxaluria, an inborn error of metabolism. As an aldehyde, glyoxalate is also highly active and can modify proteins to form advanced glycosylation products (AGEs).

DL-Glyceraldehyde (Glyceric aldehyde) is produced from the action of the enzyme glyceraldehyde dehydrogenase, which converts glycerol to glyceraldehyde using NADP as a cofactor. When present at sufficiently high levels, DL-Glyceraldehyde can be a cytotoxin and a mutagen. A cytotoxin is a compound that kills cells. A mutagen is a compound that causes mutations in DNA. DL-Glyceraldehyde is a highly reactive compound that can modify and cross-link proteins. DL-Glyceraldehyde modified proteins appear to be cytotoxic, depress intracellular glutathione levels, and induce reactive oxygen species (ROS) production (PMID: 14981296 ). DL-Glyceraldehyde has been shown to cause chromosome damage to human cells in culture and is mutagenic in the Ames bacterial test.

10-(Phosphonooxy)decyl methacrylate (10-methacryloyloxydecyl dihydrogen phosphate) is an adhesive that can modify the surface of dentin and improve the stability of dentin bonding.

DL-2-AMINOOCTANOIC ACID, also known as α-aminooctanoic acid or α-aminooctanoic acid, can be used as a modifier to modify Na-MMT clay.

Medrysone (6α-Methyl-11β-hydroxyprogesterone) is a topical, synthetic glucocorticoid with metabolic, anti-inflammatory and anti-allergic properties. Medrysone exerts its effect by interacting with specific intracellular glucocorticoid receptors and subsequently binds to DNA to modify gene expression. This results in an induction of the synthesis of certain anti-inflammatory proteins while inhibiting the synthesis of certain inflammatory mediators. Consequently, an overall reduction in chronic inflammation and autoimmune reactions is accomplished.

N6-Methyladenosine is a methylated adenine residue, glycoside is an endogenous uridine product of transfer RNA degradation. It is the most prevalent internal modification of messenger RNA present in all higher eukaryotes and can modify viral RNA with antiviral activity.

Ac-rC Phosphoramidite can modify phosphodisulfide oligonucleotides.

DMT-2′Fluoro-dU Phosphoramidite (2'-F-dU Phosphoramidite) can be used to modify nucleosides.

Mal-amido-PEG1-C2-NHS ester is a noncleavable antibody-drug conjugate (ADC) linker that incorporates a maleimide functional group and an N-hydroxysuccinimide (NHS) ester. The NHS ester offers a means to specifically modify primary amines (-NH2) present in proteins, amine-modified oligonucleotides, and other amine-containing molecules[1][2].

CGP-28014 is an inhibitor of catechol-O-methyltransferase. CGP-28014 increases the renal excretion of both dopamine and dihydroxyphenylacetic acid (DOPAC) but does not affect renal sodium handling indicating a different mechanism of action. CGP-28014 sign

(+)-Biotin 4-amidobenzoic acid is a substrate of biotinidase, which cleaves biotin amide to give biotin in vivo. Biotin is an essential coenzyme for certain carboxylases and is used to modify histones and regulate gene transcription. Biotinidase has key roles in intestinal absorption of biotin, the transport of biotin in plasma, and in the regulation of histone biotinylation. (+)-Biotin 4-amidobenzoic acid is hydrolyzed by biotinidase to release 4-aminobenzoic acid (PABA), which can be quantified by either fluorescent or colorimetric methods. This approach is used in biotinidase activity assays in newborn screening protocols to evaluate biotinidase deficiency.

Myristoyl coenzyme A (myristoyl-CoA) is a derivative of CoA that contains the long-chain fatty acid myristic acid . It is a substrate for N-myristoyltransferase during myristoylation, a process that adds a myristoyl group to proteins either during translation to modify protein activity or post-translationally in apoptotic cells. It is also a substrate in the de novo synthesis of phosphatidylinositol .

CAY10410 is an analog of prostaglandin D2/prostaglandin J2 (PGD2/PGJ2) with structural modifications intended to give it PPARγ ligand activity and resistance to metabolism. 15-deoxy-δ12,14-PGJ2 has been shown to be a potent ligand for PPARγ. Metabolism of the cyclopentenone prostaglandins PGA2, PGJ2, and δ12-PGJ2 occurs via glutathione addition across the α,β unsaturated enone. CAY10410 was designed as an analog of the PPARγ-binding prostaglandins which could not undergo this conjugation reaction. In human neuroblastoma SH-SY5Y cells, CAY10410 was not cytotoxic at up to 25 μM. It also failed to covalently modify thioredoxin or induce oxidative stress at 50 μM.
