The present invention relates to a chemical compound of the formula (I):
1
in which R
1
is:
2
R
2
is H, alkyl, which may optionally be substituted by halogen or N
2
, or NH
2
;
m and o are 0 to 3 and n is 0 or 1;
a
p
, b
q
and c
r
are amino acid chains and p, q and r denote the number of amino acids, where a and/or b and/or c may likewise comprise at least one side chain represented by (CH
2
)
m
Y
n
(CH
2
)
o
C(Z)R
2
where Y, Z, R
2
, m, n, and o have the same meanings as in formula (I), and p, q and r may be identical or different and are an integer from 0 to 1000;
R
3
and R
4
are, independently of one another, H, alkyl, aryl, a heterocycle, an amino protective group or a carboxyl protective group;
R
5
and R
6
are, independently of one another, alkyl which may comprise at least one heteroatom selected from N, O and S, aryl or a heterocycle;
X is a methine group, a nitrogen or phosphorus atom;
Y is an oxygen atom, sulfur atom or an NH group; and
Z is an oxygen atom, sulfur atom or an NR
7
group, where R
7
is H, alkyl, aryl, a heterocycle, O-alkyl, O-aryl, O-heterocycle, NR
2
or NHCONR
2
, where R is H, alkyl, aryl or a heterocycle, and to the use thereof as inhibitor of transglutaminases.
