The compounds and pharmaceutical compositions of the present invention are believed to significantly inhibit Dyrk 1a activity which suggests that the agents could provide therapeutic benefit for Down syndrome, since Dyrk 1a overproduction in Down syndrome appears to account for the developmental cognitive impairment and reduction in neurogenesis. The compounds and pharmaceutical compositions, administered during early post-natal development, may increase neurogenesis and thereby reduce cognitive impairment which may ultimately allow individuals with Down syndrome to live a more independent life.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
