[资源] 药物从研发到上市的命名变化(转)

The vast majority of chemicals that are synthesized
in medicinal chemistry research never make it to the
market place and it would be impractical to name
them all. Instead, research groups label them with a
code which usually consists of letters and numbers.
Th e letters are specific to the research group undertaking the work and the number is specific for the compound. Th us, Ro31-8959, ABT-538, and MK-639 were
compounds prepared by Roche, Abbott, and Merck
pharmaceuticals respectively. If the compounds concerned show promise as therapeutic drugs they are
taken into development and named. For example, the
above compounds showed promise as anti-HIV drugs
and were named saquinavir, ritonavir, and indinavir
respectively. Finally, if the drugs prove successful and
are marketed as medicines, they are given a proprietary,
brand, or trade name, which only the company can use.
For example, the above compounds were marketed as
Fortovase
®
, Norvir
®
and Crixivan
®
respectively (note
that brand names always start with a capital letter and
have the symbol R or TM to indicate that they are registered brand names). Th  e proprietary names are also
specific for the preparation or formulation of the drug.
For example, Fortovase
®
(or Fortovase
TM
) is a preparation containing 200 mg of saquinavir in a gel-filled,
beige-coloured capsule. If the formulation is changed,
then a different name is used. For example, Roche sell
a different preparation of saquinavir called Invirase
®
which consists of a brown/green capsule containing 200 mg of saquinavir as the mesylate salt. When a
drug’s patent has expired, it is possible for any pharmaceutical company to produce and sell that drug as
a generic medicine. However, they are not allowed to
use the trade name used by the company that originally
invented it. European law requires that generic medicines are given a recommended International Nonproprietary Name(rINN), which is usually identical to
the name of the drug. In the UK, such drugs were given
a British Approved Name(BAN), but these have now
been modified to fall in line with rINNs.
As the naming of drugs is progressive, early research
articles in the literature may only use the original letter/
number code as the name of the drug had not been allocated at the time of publication.
Throughout this text, the names of the active constituents are used rather than the trade names, although
the trade name may be indicated if it is particularly
well known. For example, it is indicated that sildenafil
is Viagra
®
and that paclitaxelis Taxol
®
. If you wish to
