## Abstract

The present invention relates to substituted pyrrole compounds which modulate the activity of protein kinases and are therefore useful in treating diseases caused by dysregulated protein kinase activity, in particular Jak family kinases. The present invention also provides methods for preparing these compounds, pharmaceutical compositions comprising these compounds, and methods of treating diseases utilizing such compounds or the pharmaceutical compositions containing them.
