Formula:C20H27NO3Purity:Min. 95%Molecular weight:329.4 g/mol(S)-Rabeprazole sodium
CAS:(S)-Rabeprazole sodium is an anticancer drug that acts as a kinase inhibitor. It is an analog of Rabeprazole and has been shown to inhibit the growth of cancer cells in vitro and in vivo. (S)-Rabeprazole sodium inhibits the activity of kinases, which are enzymes that play a key role in cell signaling pathways. This inhibition leads to apoptosis, or programmed cell death, in cancer cells. (S)-Rabeprazole sodium has been tested against various types of cancer, including Chinese hamster ovary cells and tumor xenografts in mice. It has also been shown to inhibit elastin degradation, which is important for preventing metastasis of cancer cells. (S)-Rabeprazole sodium may be a promising candidate for the development of new anticancer drugs that target specific kinases and proteins involved in cancer cell growth and survival.

Formula:C24H27NO4Purity:Min. 95%Molecular weight:393.48 g/molLinagliptin impurity G
CAS:Linagliptin impurity G is an impurity in the drug product Linagliptin. It is a natural substance and its CAS number is 668270-11-9. Impurity G can be synthesized from L-phenylalanine and cyclohexane carboxaldehyde in a two step process. The first step involves the reaction of L-phenylalanine with cyclohexane carboxaldehyde to yield methylcyclohexanecarboxylate, which then undergoes hydrolysis to give phenylcyclohexanol. In the second step, phenylcyclohexanol reacts with hydrochloric acid to produce phenylcyclohexanone, which is then oxidized with hydrogen peroxide to yield impurity G. Impurity G can also be found in the pharmacopoeia as a high purity HPLC standard for linagliptin.
