Don’t we just love the fact that these days so much
bioactivity data is freely available at no cost (to the end user)? I think we do. The
more, the better. So, what would your answer be if someone asked you if you
consider it to be a good idea if they would deposit some of their unpublished bioactivity
data in ChEMBL? My guess is that you would be all in favour of this idea. 'Go
for it', you might even say. On the other hand, if the same person would ask you
what you think of the idea to deposit some of ‘your bioactivity data’ in ChEMBL
the situation might be completely different.
First and foremost you might respond that
there is no such bioactivity data that you could share. Well let’s see about
that later. What other barriers are there? If we cut to the chase then there is
one consideration that (at least in my experience) comes up regularly and this
is the question: 'What’s in it for me?' Did
you ask yourself the same question? If you did and you were thinking about
‘instant gratification’ I haven’t got a lot to offer. Sorry, to disappoint you.
However, since when is science about ‘instant gratification’? If we would all
start to share the bioactivity data that we can share (and yes, there is data
that we can share but don’t) instead of keeping it locked up in our databases
or spreadsheets this would make a huge difference to all of us. So far the main
and almost exclusive way of sharing bioactivity data is through publications
but this is (at least in my view) far too limited. In order to start to change
this (at least a little bit) the concept of ChEMBL supplementary bioactivity
data has been introduced (as part of the efforts of the Open PHACTS project, http://www.openphacts.org).
Here is how it works: If you have unpublished bioactivity
data that has been generated in an assay that can be found in ChEMBL (since the
publication where the assay is described is also in ChEMBL), you can now
deposit this data in ChEMBL (see http://dx.doi.org/10.6019/CHEMBL2094195 for an example). The obvious
situation would be one where only a subset of the results have been reported in
the publication but there are many more results (e.g. inactives). If you work
in an industrial setting and might feel that you are not be in a position to
release additional chemical structures you could think about depositing
bioactivity data for compounds in (older) patents. Or you have reported
bioactivity data in a poster. These are only examples and there are many more
opportunities. In some cases we might explore new territory and the progress
might be slow, but if we don’t try new things we are stuck with what we have. 'Do
we really want this?' I hope the answer is no. So, let’s not focus on ‘instant
gratification’ but help to grow the body of freely available bioactivity data
by contributing to ChEMBL supplementary bioactivity data. If we could just give
it a go it might make a difference. The concept might be quite restricted (e.g.
the assay needs to be published) but we need to start somewhere. If you want to
find out more about ChEMBL supplementary bioactivity data why not drop ChEMBL
Help a line (chembl-help@ebi.ac.uk) and put ‘ChEMBL supplementary bioactivity
data’ in the subject field. And don’t worry, you are not committing yourself by
wanting to know more.
ChEMBL, and the whole world of drug discoverers, is looking forward to hearing from you.
