One aspect of the invention provides a composition of novel high penetration compositions (HPC) or a high penetration prodrug (HPP) for treatment of Parkinson's disease. The HPCs/HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPCs/HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

Isoquinoline compounds for treating various diseases and pathologies are disclosed. More particularly, the present disclosure concerns the use of an isoquinoline compound or analogs thereof, in the treatment of disorders characterized by the activation of Wnt pathway signaling (e.g., cancer, abnormal cellular proliferation, angiogenesis, Alzheimer's disease, lung disease, inflammation, auto-immune diseases and osteoarthritis), the modulation of cellular events mediated by Wnt pathway signaling, as well as neurological conditions/disorders/diseases linked to overexpression of DYRK1A.

The invention concerns particular compounds of the iminosugars class, with a piperidine ring, having a D-gluco configuration and comprising a quaternary centre in the a position of the nitrogen of the piperidine ring. These compounds have the ability to stabilize human acid α-glucosidase while being selective with respect to other glycosidases. They are particularly advantageous for use as chaperone molecules of this enzyme for the treatment of Pompe disease.
