A
Okay,
thanks
for
coming
along
everybody,
sixth
of
august,
open
source,
antibiotics
series-
two,
I
think
a
lot
of
things
are
in
progress
at
the
moment,
so
I
just
wanted
to
sort
of
catch
up
and
make
sure
we're
not
missing
anything
and
make
sure
everyone's
on
the
same
page
about
where
we
are
and
what
we're
doing,
because
it's
august
and
yeah
people
are
on
vacation,
and
so
this
is
probably
our
last
august
meeting.
A
While
things
are
chugging
along
the
background,
unless
something
important
happens,
and
we
want
to
call
a
quick,
a
quick
meeting,
but
we
don't,
I
don't
think
we
need
some
for
for
a
while.
The
the
main
reason
why
we
didn't
get
together
last
time
last
week
were
these
results.
A
That
came
through
from
paul,
where
we
we
had
some
interesting
data
back
for
for
mssa,
but
the
the
mercer
results
were
a
little
bit
off
in
the
sense
that
the
control
compound
gave
nothing
so
gave
you
an
activity,
and
so
I
think
that
we're
going
to
have
to
so.
I
asked
paul
if
he
could
redo
that
essay
and
he
said
no
problem.
It's
just
that,
as
with
most
other
people
he's
on
vocation
for
a
bit
so
we'll
get
to
this
at
the
beginning
of
september.
So
we
have
a
bit
of
a
delay
there.
B
Do
you
think
it
would
be
worth
adding
on
other
compounds,
because
I
think
ed
ed's
been
making
some
new
stuff
yeah?
Oh.
A
B
No
we'll
have
to
just
well,
I
mean
at
least
we'll
get
all
the
data
in
one
big
look
at
data
in
one
big
chunk
from
new
and
old
compounds
alike.
A
Yeah
so
yeah,
if
we
have
anything
else
for
sure
I
mean
you
know,
we're
obviously
interested
in
these
compounds
and
we
want
to
so.
If
the
mssa
dead
or
anything
to
go
by,
then
there
are
some
actives
in
here.
I
guess
that's,
that's
one
thing,
but
you
could
we
just
impossible
to
conclude,
we.
A
Yep,
so
so
we
have
to
wait
unfortunately
and
yeah,
but
anything
comes
in
in
the
meantime
we
can
add
it.
I'm
sure.
I
think
that
there
was
a
I
think.
Paul
mentioned
to
me.
There
was
a
small
change
in
his
in
his
mercer
essay
that
he
recently
bought
in
something-
and
I
forget
what
it
is
sorry
so
there
there
is
a
change
that
that
could
explain
why
the
data
don't
quite
work
for
mersa
in
this
case,
so
he's
very
happy
to
redo
it.
I.
C
A
Okay,
so
that's
what
we
have
to
do,
unfortunately,
but
that's
the
way
it
is
and
then
the
other
compounds
have
gone
to
dndi,
so
dana
dana
shipped
those
a
few
days
ago
right.
So
they
have
gone
for
testing
against
the
other
pathogens,
which
is
great.
So
I
guess
we.
A
A
I
don't
know
what
the
pipeline
is
like
either.
Sorry,
okay
and
then
you
know
alex
is
still
working
on
the
talks
and
I
will
I
will
catch
up
with
her
to
see
how
that
is
going,
because
we
need
that
for
our
paper
and
whatever
in
whatever
form,
and
then
I
was
just
going
to
mention
one
other
thing
briefly,
which
is
oh
the
mechanism.
A
Action
stuff
lee
is
is
on
the
case
and
is,
I
think,
searching
for
the
relevant
compounds
that
we
need
to
run
those
experiments
and
just
correct
if
I'm
wrong,
but
sorry
I'm
just
bringing
it
up
now,
because
there
was
a
comment,
I
think
from
him
about
whether
they
have
enough
compound-
and
he
said
something
like
he's
yeah.
He
hasn't
got
any
comment
left,
but
he
thinks
he
might
be
able
to
get
some
from
some
other
team
member
from
tim
wilson's
group.
A
So
we
just
got
to
chase
that
that
was
a
few
days
ago.
So
I
think
we've
just
got
to
make
sure
that
he
has
enough
so
that
he
can
run
those
experiments.
He
has.
He
has
the
funding
and
he
has,
I
think,
the
person
to
do
it,
so
he's
just
got
to
make
sure
it's
scheduled
in
in
good
time.
A
I
I
checked
on
the
grant
status
over
there
and
there's
still
there's
still
money
left
for
him
to
cover
these
experiments,
so
we're
in
good
shape
for
that
all
right
and
then
just
on
the
the
chemistry
so
so
giada.
He
has
those
two
compounds
in
the
the
mercer
evaluation
and
is
finished
in
the
lab.
There
were
some
other
molecules
that
we
could
make
in
theory.
A
If
we
see
activity
there,
then
we
might
want
to
continue
to
push
those
with
the
variation
in
the
in
the
northwest
position
with
a
means
up
in
that
position,
and
then
I
think
that
ed,
you
were
done
with
compounds
that
you
were
making
for
this
series.
There's
nothing
else
in
the
pipeline
here.
A
Three
new
ones
that
that
are
two
go
in
right
in
the
next
round,
so
we
can
add
those
to
the
current
shipment
right
to
paul
right
and
then
dana
was
doing
the
one
parts
hi
there.
A
Lost
track
of
time,
don't
worry.
We
were
just
saying
that,
along
with
the
re-evaluation
of
the
compounds
in
paula's
assay
that
we
can
add
in
any
other
compounds
that
are
coming,
would
that
include
some
from
from
your
warm
pots
is
more
coming
through
there.
C
B
Was
another
right
and
there
was
another
possible
compound
I
posted
about-
maybe
another
chord
change
could
be
done.
There's
a
precursor!
That's
not
that
expensive,
two
amino
pyrazine
and
six
another
nitrogen
on
the
core.
If
you
scroll
down,
you
should
see
it
on
that.
A
C
Yeah
one
thing
I
think
that
maybe
we
should
do
is
like
the
match
pair
to
1002,
just
with
the
methyl,
I
I
don't
think
that's
actually
been
tested
and
a
lot
of
our
compounds
kind
of
match.
Back
to
that,
so
I
was
going
to
look
at
making
a
bit
of
that
unless
you
have
some
at
any.
U
I
mean,
I
assume
that
you
guys
would
have
made
that
compound,
but.
C
Yeah
yeah
I
was,
I
was
just
looking
through,
and
I
noticed
that
we've.
Never
we
didn't
actually
have
that.
Just
the
methyl,
which
I
think
you
know
in
terms
of
publication,
would
be
good
for
as
a
benchmark
right.
D
Compound
back,
it's
equally
metabolized
as
as
the
actual
methyl,
so
the
isotope
didn't
help
with
the
overall
metabolism.
Something
we
did
observe,
though,
is
about
a
10-fold
improvement
in
the
selectivity,
so
it
was
significantly
less
cytotoxic
to
the
host
cell.
D
Yeah
yeah
I'd
expect.
I
expect
it
to
be
a
little
bit
less
lipophilic,
based
on
sort
of
the
size
as
well
as
sort
of
the
deuterium
effect
on
the
felicity,
but
not
not
to
the
extent
that
we
saw
what.
B
Obviously,
would
it
wonder
if
I
posted
a
seat
yeah
almost.
B
On
on
the
six
membered,
the
five
six
core,
if
we
pop
that
off,
put
deuterium
on
there,
that'd
be
interesting.
A
D
So
that's
why
we
looked
at
putting
it
on
for
the
n
methyl
because
it's
obviously
an
unknown
metabolic
liability
in
the
series.
But.
D
D
No,
no
real
answer
is,
is
the
truth
behind
it,
like?
Maybe
you
could
say
that
in
the
actual
whole
cell
itself
there
was
some
metabolism
and
there
was
a
toxic
metabolite
forming
yeah
that
that
isn't
forming
with
the
deutero
compound
by
the
end,
methylation,
but
that's
very
hand
wave,
and
we
have
no
evidence
behind
it.
Yeah.
D
Yeah
exactly
right,
especially
with
the
long
incubation
times
but
yeah
like
no
evidence
behind
it
and
it'd,
be
very
hand-wavy
to
say
that.
A
Okay
and
then
yes,
so,
while
we're
looking
at
this,
the
yeah
anthony,
you
had
a
an
example
of
another
called
another
purity,
nitrogen
that
you
were
suggesting
here
right.
It's
not
that
expensive!
It's.
D
D
If
that's
the
case,
once
again,
I've
got
about
every
single
positional
analog
of
the
nitrogen
in
that
core
I've
already
made
with
the
four
fluorophenyl.
So
if
you're
interested
in
those
just,
let
me
know-
and
I
could
do
the
the
isobutyl
alkylation
to
the
entire
suite
wow.
B
A
B
Even
even
in
methyl
or
in
it
or
an
ethylation,
to
save
your
time,
because
it
seems
like
all
right,
like
there's,
probably
a
way
to.
D
G
A
So
the
nitrogen
isomers
of
the
throne
right
is
what
you're
talking
about
the
position.
That's
right!
That's
right!
Right,
yep!
So.
A
A
Okay,
that
is
interesting
just
to
see
what
we
could
do
with
that,
it's
just
offline
dana.
Would
you
just
mind
talking
to
equivalent
about
the
availability
of
those
materials
and
just
checking
what
we
can
do
with
that?
Is
that
really
handy
and
then
maybe
posting
something
here
about
what
we
can
then
access
by
by
working
with
colon
on
those
molecules?
A
That's
really
interesting:
yeah,
okay
and
then
the
last
thing
yeah
there
was
just
the
the
comment
from
laurie
who
couldn't
join
us
today
about
the
these
compounds
that
we
were
talking
about
previously.
A
Not
these
sorry
yeah.
I
guess
I
guess
the
I
I
assume
she's
talking
about
these
compounds
here
where
the
idea
was
to
put
on
the
the
alkyl
group,
and
I
think
you
were
saying
that
the
in
order
to
do
that
we'd
need
to
you
guys
would
need
to
resynthesize
some
of
the
core
and
we
would
just
needed
to
discuss
whether
whether
that
was
still
an
aim
is
have
I
got
that
right
or
have
I.
D
Were
selected
for
you
so
when
I
went
and
had
a
look
at
now
stocks
of
these,
I
think
the
original
plan
these
were
meant
to
all
be
in
stock,
but
several
of
them
aren't
okay
or
at
least
not
enough
to
push
through
to
the
to
the
final
compound.
D
So
I
was
asking
about
the
the
three
five
difluro,
for
example.
Was
that
something
were
interested
in
or
was
it
just
by
chance
that
we
were
meant
to
have
it
on
stock.
D
Yeah
so
from
our
point
of
view,
it
makes
just
as
much
sense
to
make
the
four
floor
of
fennel
and
save
down
on
making
multiple
different
compounds.
D
So
yeah,
so
I'm
I
think
larry
was
just
sort
of
getting
out
with
the
components
of
this
that
were
truly
interesting
to
you
or
is
it
out
of
convenience?
And
if
it's
out
of
convenience
you
assuming
we're
going
to
have
to
resynthesize
some
of
these
if
they're
anything
that
you're
more
interested
that
can
fit
in
with
the
sar
that
you're
of
your
program,
let
us
know
because
it's
it's
just
the
same
amount
of
effort's
going
to
be
put
in.
So
why
not
make
more
impactful
compounds.
B
A
At
this
stage,
the
main
thing
was
to
explore
the
alkylation
of
the
nitrogen,
because
that
was
giving
us
the
most
promising
data.
I
mean
that
was
pretty
much
as
far
as
we
got,
and
so
I
think
the
idea
was
to
try
and
add
on
the
same
group
to
the
nitrogens
here,
whilst
exploring
the
rest
of
the
core
to
see.
If
we
could,
you
know,
combine
potency
associated
with
the
n,
alcohol
and
other
bits
of
the
molecule
and
because
they're
available,
we
thought
well.
A
D
Well,
because,
assuming
I'm
already
teaming
up
with
dana
to
discuss
some
of
those
core
modifications
anyway,
I
can
let
her
know
what
we
have
on
hand
immediately
now,
and
we
can
sort
of
talk
offline
about
that.
A
Generating
data
on
these
nh
compounds
is
just
less
desirable
than
alcohol
and
that
that
was
the
reason
we
just
wanted
to
to
try
and
populate
the
sar
a
little
bit
more
so
yeah
don't
want
you
to
have
to
synthesize
a
bunch
of
things
when
a
a
smaller.
A
A
A
Okay,
that
would
be
good,
because
that
would
because
those
who
go
in
the
next,
all
assay
yeah,
which
would
be
good
if
they
come
in
the
next
couple
weeks,
all
right,
okay,
I
think
that
was
pretty
much
everything
we
don't
have
flavia
on
the
call
right
to
tell
us
how
the
homology
series
is
going,
because
that
would
be
really
nice
too.
A
If
he
was
able
to
ship
those
in
the
next
couple
of
weeks,
I
will
catch
up
with
him
offline
to
see
how
that's
going
and
whether
or
not
we
could
expect
something.
It
should
be
very
convenient
I'll.
Also
try
and
do
this
newsletter-
that's
been
on
me
for
ages.
During
my
research
break,
okay
was.
A
Wanted
to
mention
or
that
we
should
be
planning
for
the
next
few
weeks.
I
think
we,
you
know,
we
still
need
the
the
this
crucial
sar
data
and
all
the
molecules
that
we're
talking
about,
and
we
still
need
the
moa
results
from
lee,
and
these
are
priorities
for
for
this
month
during
the
vacation
time.
A
All
good,
okay!
Well
great!
I
think
we
will
have
you
know
a
few
weeks
off
and
we
can
discuss
online
and
then
have
first
meeting
back.
I
think
at
the
beginning
of
the
beginning
of
september,
so
I
think
it's
that
september
third
will
be
the
next
one,
if
that's
okay
with
everybody,
so
we
can
communicate
online
as
per
usual.
