RS 67506 hydrochloride has been shown to have a number of biological properties, including inhibition of the synthesis of neurotransmitters such as dopamine, serotonin and norepinephrine; it also has anti-nervous system activity. This chemical was also found to inhibit the synthesis of prostaglandin E2 in human neutrophils. It is hypothesized that RS 67506 hydrochloride may inhibit phospholipase A2, which would prevent the release of arachidonic acid from phospholipids into the cell membrane and block the production of eicosanoids.

Discontinued productDesmethyl dabrafenib
CAS:Desmethyl dabrafenib is a synthetic drug product that is used in research and development. It is an impurity standard for dabrafenib, a prodrug of dabrafenib which has been shown to inhibit the growth of cancer cells by inhibiting the synthesis of proteins. Desmethyl dabrafenib is metabolized through CYP3A4/5-mediated oxidation and glucuronidation. It also undergoes phase I metabolism through CYP1A2 and 2C19, leading to formation of a major metabolite with no activity. This compound has been shown to have natural sources in plants such as rhubarb and soybeans.

Discontinued productLysolecithin
CAS:Lysolecithin is an analog of the phospholipid lecithin that has been shown to have anticancer properties. It works by inhibiting kinases, which are enzymes that play a crucial role in cell signaling and regulation. Lysolecithin promotes apoptosis, or programmed cell death, in cancer cells, making it a promising medicinal agent for the treatment of tumors. Studies have also shown that lysolecithin can inhibit protein kinase activity in human urine and inhibit the growth of cancer cells in Chinese hamsters. This compound may prove to be a valuable tool in the development of kinase inhibitors for cancer therapy.

Discontinued productBupropion (R)-Isomer
CAS:Controlled ProductBupropion is a racemic mixture of two enantiomers. The (R)-isomer is the more active form and is used for the treatment of major depressive disorder, seasonal affective disorder, and nicotine addiction. Bupropion has been shown to inhibit monoamine oxidase type A in humans and other mammals. This inhibition may be responsible for its antidepressant effects. The drug also has an effect on the liver, which can lead to serious side effects such as seizures or death if not monitored carefully. Bupropion has a high affinity for α1-acid glycoprotein, which plays a role in drug interactions with other drugs that are metabolized by this protein.
