Never Gonna Give You Up – Current Developments in Covalent Protein Kinase Inhibitors

Never give up.

Recent developments of protein kinase inhibitors as potential AD therapeutics

Present Alzheimer's disease (AD) therapies suffer from inefficient effects on AD symptoms like memory or cognition, especially in later states of the disease. Used acteylcholine esterase inhibitors or the NMDA receptor antagonist memantine address one target structure which is involved in a complex, multifactorial disease progression. So the benefit for patients is presently poor. A more close ...

Prolonged and tunable residence time using reversible covalent kinase inhibitors

Drugs with prolonged on-target residence times often show superior efficacy, yet general strategies for optimizing drug-target residence time are lacking. Here we made progress toward this elusive goal by targeting a noncatalytic cysteine in Bruton's tyrosine kinase (BTK) with reversible covalent inhibitors. Using an inverted orientation of the cysteine-reactive cyanoacrylamide electrophile, we...

PARP Inhibitors in Reproductive System Cancers: Current Use and Developments

The repair of DNA damage is a critical cellular process governed by multiple biochemical pathways that are often found to be defective in cancer cells. The poly(ADP-ribose) polymerase (PARP) family of proteins controls response to single-strand DNA breaks by detecting these damaged sites and recruiting the proper factors for repair. Blocking this pathway forces cells to utilize complementary me...

Endogenous Protein Kinase Inhibitors

A thermostable inhibition of ATP:protein phosphotransferase (EC 2.7.1.37) (protein kinase) which is present in crude tissue extracts has been resolved by gel chromatography (Sephadex G-100) into two molecular forms. These two forms will be referred to as type I and type II inhibitor. The type I inhibitor (M, = 24,000) is specific for CAMP-dependent protein kinase and corresponds to the inhibito...
