Design of amidobenzimidazole STING receptor agonists with systemic activity.

Stimulator of interferon genes (STING) is a receptor in the endoplasmic reticulum that propagates innate immune sensing of cytosolic pathogen-derived and self DNA. The development of compounds that modulate STING has recently been the focus of intense research for the treatment of cancer and infectious diseases and as vaccine adjuvants. To our knowledge, current efforts are focused on the development of modified cyclic dinucleotides that mimic the endogenous STING ligand cGAMP; these have progressed into clinical trials in patients with solid accessible tumours amenable to intratumoral delivery.

A selective inhibitor of PRMT5 with in vivo and in vitro potency in MCL models.

Protein arginine methyltransferase-5 (PRMT5) is reported to have a role in diverse cellular processes, including tumorigenesis, and its overexpression is observed in cell lines and primary patient samples derived from lymphomas, particularly mantle cell lymphoma (MCL). Here we describe the identification and characterization of a potent and selective inhibitor of PRMT5 with antiproliferative effects in both in vitro and in vivo models of MCL. EPZ015666 (GSK3235025) is an orally available inhibitor of PRMT5 enzymatic activity in biochemical assays with a half-maximal inhibitory concentration (IC50) of 22 nM and broad selectivity against a panel of other histone methyltransferases.

The catalytic role of INCENP in Aurora B activation and the kinetic mechanism of Aurora B/INCENP.

Aurora kinases are a family of serine/threonine protein kinases that play essential roles in mitosis and cytokinesis. AurB (Aurora B kinase) has shown a clear link to cancer and is being pursued as an attractive cancer target. Multiple small molecules targeting AurB have entered the clinic for the treatment of cancer.

Modulation of kinase-inhibitor interactions by auxiliary protein binding: crystallography studies on Aurora A interactions with VX-680 and with TPX2.

VX-680, also known as MK-0457, is an ATP-competitive small molecule inhibitor of the Aurora kinases that has entered phase II clinical trials for the treatment of cancer. We have solved the cocrystal structure of AurA/TPX2/VX-680 at 2.3 A resolution.

Binding of TPX2 to Aurora A alters substrate and inhibitor interactions.

The Aurora kinases are a family of serine/threonine kinases involved in mitosis. The expression of AurA is ubiquitous and cell cycle regulated. It is overexpressed in many tumor types, including breast, colon, and ovarian.
