An impurity of Atazanavir

Desbenzyl Donepezil Hydrochloride is an impurity of Donepezil, which is a centrally acting reversible acetyl cholinesterase inhibitor for the treatment of moderate to severe Alzheimer’s disease.

5,6-Dimethoxy-2-(4-pyridylmethylene)-1-indanone is one of Donepezil impurities. Donepezil, a highly specific reversible acetylcholinesterase (AChE) inhibitor, is used to treat moderate to severe Alzheimer’s disease.

Pemetrexed binds to and inhibits the enzyme thymidylate synthase (TS) which catalyses the methylation of 2′-deoxyuridine-5′-monophosphate (dUMP) to 2′-deoxythymidine-5′-monophosphate (dTMP), an essential precursor in DNA synthesis.

An impurity of Pemetrexed, which has been approved by FDA in 2004 for the treatment of malignant pleural mesothelioma (MPM) in combination with cisplatin, a platinum-containing chemotherapeutic drug.

Pemetrexed diethyl ester is one of pemetrexed intermediates. Pemetrexed binds to and inhibits the enzyme thymidylate synthase (TS) which catalyses the methylation of 2′-deoxyuridine-5′-monophosphate (dUMP) to 2′-deoxythymidine-5′-monophosphate (dTMP), an essential precursor in DNA synthesis.
