The Concept of Pharmaceutical Intermediates
Pharmaceutical intermediates are intermediate chemicals made in the process of chemical drug synthesis, belonging to fine chemical products, whose upstream industry is the basic chemical raw material manufacturing industry, and the downstream industry is the chemical drug API and preparation manufacturing industry. The synthesis of chemical drugs depends on high-quality pharmaceutical intermediates. This kind of chemical products, do not need the production license of drugs, can be produced in the ordinary chemical factory, as long as to achieve some level, can be used in the synthesis of drugs.
Take nucleotide intermediates as an example: they are compounds produced as an intermediate step in the synthesis of nucleotide drugs. Nucleotides are composed of nucleosides and phosphoric acid, and are the building blocks of important biomolecules in living organisms, including DNA and RNA. Nucleotide intermediates include:
1. nucleoside intermediates: such as deoxyribonucleotide (dNTP), nucleotide diphosphate (NTP), deoxyribonucleotide triphosphate (dNTP), nucleotide triphosphate (NTP) and so on.
2. Nucleotide intermediates: such as deoxyribonucleotide diphosphate (dNTP), nucleotide triphosphate (NTP), deoxyribonucleotide triphosphate (dNTP), nucleotide tetraphosphate (NTP) and so on.
These nucleotide intermediates play an important role in the process of drug synthesis and can be further transformed through different chemical reactions to eventually form nucleotide drugs with specific pharmacological activities.
