The present invention relates to certain substituted 1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid derivatives of Formula (Ia) and pharmaceutically acceptable salts thereof, which exhibit useful pharmacological properties, for example, as agonists of the S1P1 receptor.

##STR00001##

Also provided by the present invention are pharmaceutical compositions containing compounds of the invention, and methods of using the compounds and compositions of the invention in the treatment of S1P1 receptor-associated disorders, for example, psoriasis, rheumatoid arthritis, Crohn's disease, transplant rejection, multiple sclerosis, systemic lupus erythematosus, ulcerative colitis, type I diabetes, acne, microbial infections or diseases and viral infections or diseases.

Certain aspects of the invention relate to compounds, compositions and methods that are useful for treating or preventing a disease in a subject by enhancing the degradation of a protein. In other aspects, said compounds can be useful research tools for investigating protein degradation. In other aspects, said compounds are useful research tools for investigating protein function. In certain embodiments, the degraded protein is implicated in a disease or disorder whose pathology is related at least in part to the excessive expression of the protein or the expression of a mutant form of the protein.
