The invention relates to a group of novel thieno-pyrrole compounds of Formula (I): wherein: R1, R2, R3, R4 and R5 are as defined in the specification, which are useful as gonadotrophin releasing hormone antagonists. The invention also relates to pharmaceutical formulations of said compounds, methods of treatment using said compounds and to processes for the preparation of said compounds.
The compounds of the invention are compounds represented by the following general formula (1):
1
wherein E represents one selected from the group consisting of a methylidyne group and a nitrilo group, R
1
represents one selected from the group consisting of optionally substituted aryl groups and optionally substituted heteroaryl groups, R
2
represents one selected from the group consisting of a hydrogen atom and alkyl groups, W
1
represents an amino acid residue, A represents one selected from the group consisting of a carbonyl group and a sulfonyl group, X
1
represents one selected from the group consisting of optionally substituted alkylene groups and optionally substituted alkenylene groups, and p represents 0 or 1;
and their pharmacologically acceptable salts, which exhibit thrombopoietin-like activity.

The electron impact (EI) induced massspectral fragmentation of seventeen, including seven newly synthesized, N-1 and C-6carboxyalkyl- and alkoxycarbonylalkyl-substitutedderivatives of uracil and thymine was investigated. Fragmentation pathways are proposed on the basis of accurate mass and metastable transition measurements. The correlation between the intensities of the M+* and selected fragment
