CAS:Controlled Product2-Amino-4'-chloroacetophenone hydrochloride is a cytotoxic compound that inhibits the polymerization of tubulin. It has been shown to have cytotoxic effects and inhibit the growth of cancer cells in vitro at low micromolar concentrations. 2-Amino-4'-chloroacetophenone hydrochloride is a member of the cytotoxic class of compounds and can be used to slow or stop cell division by inhibiting the production of proteins vital for cell division, such as tubulin. This effect is due to its ability to bind to the beta subunit of tubulin, which disrupts its structure and prevents polymerization from occurring.

Discontinued product3-(4-Methylbenzylidene)camphor
CAS:3-(4-Methylbenzylidene)camphor is a chemical compound that has two isomers, alpha and beta. It can be found in biological samples, such as human urine or wastewater, and can be used for the treatment of skin cancer. 3-(4-Methylbenzylidene)camphor is prepared by extraction from a dry sample with an organic solvent. The extraction process requires a hydroxyl group to react with the dry sample and create a liquid. The resulting liquid is then evaporated to leave behind the extract. The kinetic data of 3-(4-Methylbenzylidene)camphor was determined by measuring its rate of reaction with an analytical method. The rate of reaction increased as the concentration increased to a constant value at high concentrations, which suggests that it may have some occlusive properties in humans due to its tendency to bind to plasma proteins.

Discontinued productDipyrone
CAS:Dipyrone is an anti-inflammatory and analgesic drug that belongs to the group of non-steroidal anti-inflammatory drugs. It has been shown to inhibit the production of prostaglandins, which are involved in inflammation, by inhibiting cyclooxygenase. The polymerase chain reaction (PCR) method is a biochemical technique used to amplify a segment of DNA, typically for use as a genetic marker or for cloning a particular gene. A PCR assay can be used to detect the presence of bacterial DNA in a sample. Dipyrone has been shown to possess chemiluminescence activity, which is indicative of its ability to bind with DNA. This binding inhibits transcription and replication and may be responsible for the toxic effects on epidermal cells observed in animal studies. Dipyrone also has been shown to have anti-inflammatory activities through its inhibition of cyclooxygenase and its ability to inhibit neutrophil migration and function.

Discontinued productSodium sarcosinate - ca. 40% in water
CAS:Sodium sarcosine is a salt of sarcosine with sodium. It has an average molecular weight of 255 and is soluble in water. Sodium sarcosine is used as a biological sample for non-steroidal anti-inflammatory drugs (NSAIDs) in the study of their inhibitory properties against mammalian DNA polymerase. NSAIDs are also used to treat inflammation, pain, and fever by inhibiting prostaglandin synthesis. The rate constant for the reaction between NSAIDs and DNA polymerase was found to be 1.6x10^-4 M^-1s^-1 at 25°C, which is close to the Km value for the reaction. This finding indicates that NSAIDs may be competitive inhibitors of the enzyme, although further experiments are needed to confirm this hypothesis. Using electrochemical impedance spectroscopy, it was found that NSAIDs have a higher affinity for divalent cations than monovalent cations, suggesting that they bind to a site on the
