Novel potent and selective pyrazolylpyrimidine-based SYK inhibitors.

Hybridisation of amino-pyrimidine based SYK inhibitors (e.g. 1a) with previously reported diamine-based SYK inhibitors (e.

Optimization of a series of potent, selective and orally bioavailable SYK inhibitors.

Spleen tyrosine kinase (SYK) is a non-receptor cytosolic kinase. Due to its pivotal role in B cell receptor and Fc-receptor signaling, inhibition of SYK has been targeted in a variety of disease areas. Herein, we report the optimization of a series of potent and selective SYK inhibitors, focusing on improving metabolic stability, pharmacokinetics and hERG inhibition.

A case of extramedullary solitary plasmacytoma arising at the uterine cervix.

Extramedullary plasmacytomas are localized plasma cell neoplasms that arise in tissues other than bone and bone marrow. Primary plasmacytomas of the female genital tract are extremely rare and present a substantial diagnostic challenge. We report a case of a 38-year-old woman who presented with an endocervical polypoid.
