The invention relates to a bicyclic heteroaromatic derivative compound according to general formula (I), (see formula I) or a pharmaceutically acceptable salt thereof, wherein R1 is NR5R6, OR5, SR5 or R7 ; R5 and R6 are independently selected from H, (1-8C)alkyl, (2-8C)alkenyl, (2-8C)alkynyl, (3-8C)cycloalkyl, (2-7C)heterocycloalkyl, alkyl(1-8C)carbonyl, (6-14C)arylcarbonyl, (6-14C)aryl or (4-13C)heteroaryl, or R5 and R6 together are joined in a (2-7C)heterocycloalkyl ring; R7 is (3-8C)cycloalkyl, (2-7C)heterocycloalkyl, (6-14C)aryl or (4-13C) heteroaryl, R2 is (1-8C) alkyl, (2-8C) alkenyl, (2- 8C)alkynyl, or (6-14C)aryl or (4-13C)heteroaryl, both optionally substituted with one or more substituents selected from (1-8C)alkyl, (l-8C)alkylthio, (1-8C)(di)alkylamino, (1- 8C)alkoxy, (2-8C)alkenyl, or (2-8C)alkynyl; R3 is (1-8C)alkyl, (2-8C)alkenyl, (2-8C)alkynyl, (3-8C)cycloalkyl, (2-7C)heterocycloalkyl, or (6-14C)aryl or (4-13C)heteroaryl, both optionally substituted with one or more substituents selected from (1-8C)alkyl, (1-8C)(di)alkylamino or (1-8C) alkoxy; X is S, O or N(R4); R4 is H, (1-8C) alkyl, (1-8C)alkylcarbonyl, (6-14C)arylcarbonyl or (6-14C)aryl(1-8C)alkyl; Y is CH or N; Z is NH2 or OH; A is S, N(H), N(R9), O or a bond; R9 can be selected from the same groups as described for R2 and B is N(H), O or a bond. The compounds of the invention have LH receptor activating activity and can be used in fertility regulating therapies.
