Pregunta 2
Pregunta
biological drugs (also known as [blank_start]biologics[blank_end]) are [blank_start]large[blank_end] molecule drugs. They are usually [blank_start]proteins[blank_end] such as [blank_start]peptides[blank_end] or antibodies but could be a nucleic acid. When discovered they are referred to as a [blank_start]NBE[blank_end]

Pregunta 3
Pregunta
a blockbuster drugs earns over $10 billion a year
Respuesta
- True
- False
Pregunta 4
Pregunta
where DON'T novel small molecules come from
Respuesta
-
Nature
-
Endogenous compounds
-
In silico drug design
-
you too drugs
Pregunta 5
Pregunta
which of the following is NOT a reason why analogue synthesis is required for endogenous lead compounds?
Respuesta
-
natural ligand may have undesirable duration of action
-
natural ligand may be metabolised too quickly
-
natural ligand may be chemically unstable
-
natural ligand may not have pharmacophore
Pregunta 6
Pregunta
synthetic drugs can be designed with computer modelling software
Respuesta
- True
- False
Pregunta 7
Pregunta
a me too drug has a similar structure to an existing drug, modified enough to make the compound [blank_start]novel[blank_end], but not so much that [blank_start]activity[blank_end] is affected.
Respuesta
-
novel
-
similar
-
typical
-
normal
-
activity
-
functional groups
-
side effects
Pregunta 8
Pregunta
which one of the following is true
Respuesta
-
side effects caused by drugs are never useful
-
side effects from drugs can be useful by providing a new lead compound for the same condition
-
side effects from drugs can be useful by providing a new lead compound for a different condition
-
side effects from drugs are always useful even if no new lead compounds are found
Pregunta 9
Pregunta
The definition for a lead compound is - a novel compound discovered to have pharmaceutical potential which is a good starting point for drug development.
Respuesta
- True
- False
Pregunta 10
Pregunta
natural product derivatives are a natural derivative of a synthetic molecule
Respuesta
- True
- False
Pregunta 11
Pregunta
Natural product derivatives are used as drug compounds because they are [blank_start]less[blank_end] complex and [blank_start]smaller[blank_end] so easier to deliver, and possibly [blank_start]easier to deliver[blank_end]. The active part of the molecule may be used to save [blank_start]time and money[blank_end].
Respuesta
-
less
-
more
-
equally as
-
smaller
-
larger
-
have a higher LogP
-
easier to deliver
-
more lipinski like
-
better formulated as creams
-
time and money
-
space
-
wastage and filtration
Pregunta 12
Pregunta
Which of the following are challenges with natural products
Respuesta
-
chrial centres which leads to 10,000's of isomers
-
unusual functional groups causes complex chemistry
-
difficult and ineffective multistep synthesis
-
novel structures means scientists cannot predict LogP values
Pregunta 13
Pregunta
The large molecular weight of many natural products causes:
Respuesta
-
I.V to often be the route of administration
-
Good absorption through SGLT channels in the duodenal epithelium
-
them to be stable in the stomach due to oxygen (ether) groups
