The present invention relates to methods for treating cancer comprising utilizing a combination of signal transduction inhibitors. More specifically, the present invention relates to combinations of so called cell cycle inhibitors with mitogen stimulated kinase signal transduction inhibitors, more specifically combinations of CDK inhibitors with mitogen stimulated kinase signal transduction inhibitors, more preferably MEK inhibitors. Other embodiments of the invention relate to additional combinations of the aforesaid combinations with standard anti-cancer agents such as cytotoxic agents, palliatives and antiangiogenics. Most specifically this invention relates to combinations of 6-acetyl-8-cyclopentyl-5-methyl-2-(5-piperazin-1-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one including salt forms, which is a selective cyclin-dependent kinase 4 (CDK4) inhibitor, in combination with one or more MEK inhibitors, most preferably N-[(R)-2,3-dihydroxy-propoxy]-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide. The aforementioned combinations are useful for treating inflammation and cell proliferative diseases such as cancer and restenosis.

The invention relates to a novel synthesis method of a CDK4 (cyclin-dependent kinase 4) inhibitor. A reaction of 2-chloro-8-cyclopentyl-5-methylpyrido[2,3-d]pyrimidin-7(8H)-one with acetylchloride is taken as an initial reaction, consequent reactions are performed, and the CDK4 inhibitor is prepared; the preparation method is simple and easy to implement, the yield is high, the quality is high, and industrial production is facilitated.

Described herein is the use of CDK inhibitors such as roscovitine for inducing apoptosis of granulocytes, for example neutrophils. Their use for treating inflammatory diseases is also provided.

The present invention relates to CDK inhibitors and their use in the treatment of cell proliferative diseases such as cancer. The compounds of the invention may further act as HDAC inhibitors.

The present disclosure describes combination therapies comprising an antagonist of Programmed Death 1 receptor (PD-1) and the CDK inhibitor dincaciclib, and the use of the combination therapies for the treatment of cancer, and in particular for treating cancers that express PD-L1.

The present invention relates to a pharmaceutical combination comprising a CDK inhibitor and at least one antioxidant enzyme inhibitor for use in the treatment of cancer. The present invention also relates to a method for the treatment of cancer comprising administering to a subject in need thereof, a therapeutically effective amount of a CDK inhibitor and a therapeutically effective amount of at least one antioxidant enzyme inhibitor. The pharmaceutical combination of the present invention exhibits synergistic effect when used in the treatment of cancer.

The present invention relates to the use of one or more biomarkers to evaluate the likelihood that a CDK4 inhibitor would produce an anti-cancer effect in a subject. It is based, at least in part, on the discovery that cancer treatment with a CDK4 inhibitor is more effective where treated cancer cells undergo cellular senescence rather than a transient cell cycle arrest, where cellular senescence is associated with decreased MDM2 protein level. Accordingly, in non-limiting embodiments, the present invention provides for methods, compositions, and kits for a companion diagnostic for CDK4 inhibitors, and in particular, to the use of MDM2 expression as a biomarker for the likelihood that a cancer can be successfully treated by CDK4 inhibition.
