General Information

Gimeracil Impurities and Gimeracil

Daicel Pharma specializes in synthesizing impurities for Gimeracil, an active pharmaceutical ingredient. We offer crucial impurities such as 5-Chloro-4-methoxy-2(1H)-pyridinone / Gimeracil Impurity 7, Gimeracil Impurity 16, and Gimeracil Impurity 3, which play a vital role in evaluating the purity, and safety of Gimeracil. Daicel Pharma also provides custom synthesis of Gimeracil impurities to meet specific client needs and offer worldwide delivery options.

By inhibiting the enzyme dihydropyrimidine dehydrogenase (DPD), Gimeracil [CAS: 103766-25-2], a pyridine derivative, effectively enhances the antitumor activity of fluoropyrimidines. Gimeracil helps to increase the effectiveness of fluoropyrimidine-based drugs by preventing their breakdown in the body.

Gimeracil: Use and Commercial Availability  

When combined with cisplatin, Gimeracil, as part of the product Teysuno, treats advanced gastric (stomach) cancer in adults. It is a part of antineoplastic therapy.

Gimeracil Structure and Mechanism of Action Gimeracil Structure and Mechanism of Action

The chemical name of Gimeracil is 5-Chloro-4-hydroxy-2(1H)-pyridinone. Its chemical formula is C5H4ClNO2, and its molecular weight is approximately 145.54 g/mol.

Gimeracil prevents the breakdown of 5-FU, which acts against cancer cells. It blocks the enzyme  dihydropyrimidine dehydrogenase (DPD) responsible for the degradation of 5-FU.

Gimeracil Impurities and Synthesis

During the synthesis1 of Gimeracil, various impurities may arise. Some common impurities include related pyridine derivatives, byproducts resulting from reaction side reactions, or incomplete conversion of starting materials. They can potentially impact the purity, stability, and efficacy of Gimeracil. Therefore, stringent quality control measures help monitor and control impurity levels during the synthetic process.

Daicel Pharma, in adherence to cGMP standards, has an analytical facility where we prepare Gimeracil impurities like 5-Chloro-4-methoxy-2(1H)-pyridinone / Gimeracil Impurity 7, Gimeracil Impurity 16 and Gimeracil Impurity 3. We offer a comprehensive Certificate of Analysis (CoA) for these impurities, providing a detailed characterization report. The CoA includes data obtained through techniques, 1H NMR, 13C NMR, IR, MASS, and HPLC purity analysis2. Upon request, we provide additional data like 13C-DEPT. We can synthesize unknown Gimeracil impurities or degradation products. Each delivery has a comprehensive characterization report.
