Phthalate derivatives that are aspartate-P-semialdehyde dehydrogenase (ASADH) inhibitor compounds, aspartate N-acetyltransferase (ANAT) inhibitor compounds, or both, are described, as well as methods of making the same, and methods of using the same.
Tryptophan derivatives of formula (1) are described:
1
wherein:
Ar is an optionally substituted aromatic or heteroaromatic group;
X is an oxygen or sulphur atom;
Alk is a chain
2
in which m is zero or the integer 1 or 2 and R is a carboxylic acid (—CO
2
H) or a derivative or biostere thereof;
R
2
is an optionally substituted aliphatic group;
R
3
is an optional substituent;
n is zero or the integer 1, 2 or 3;
and the salts, solvates, hydrates and N-oxides thereof.
The compounds are able to inhibit the binding of LFA-1 to its ligands and are of use in the prophylaxis and treatment of inflammatory diseases or disorders or autoimmune diseases.
A process for producing an aromatic compound is disclosed, which comprises coupling an aromatic sulfinic acid or a salt thereof with an aromatic halogen compound having at least one halogen atom attached to a carbon atom of the aromatic nucleus thereof or a vinyl group-containing halogen compound having at least one halogen atom attached to a carbon atom of said vinyl group in the presence of a catalyst compound containing an element selected from the platinum group. metals.
