UK122 is a Selective Urokinase-Type Plasminogen Activator (uPA) Inhibitor
Urokinase, also known as urokinase-type plasminogen activator (uPA), is a serine protease found in humans and other animals. Specifically, UPA is relevant to tissue remodeling and cell migration. The active form of uPA binds to its high-affinity receptor on the cell surface, and specific inhibitors can regulate its enzyme...
DP-C-4 is a CRBN-Based dual PROTAC for EGFR and PARP
Proteolysis targeting chimera (PROTAC) is a bifunctional small molecule. Interestingly, dual PROPACs are dual-targeted degradation molecules that combine the concepts of PROTAC and dual-targeting. Dual PROPACs degrade two completely different pathway targets while simultaneously taking advantage of both PROTAC and dual-target drugs. Thus, dual PROPACs not only achieve the...
Venadaparib (IDX-1197) is a Potent and Selective PARP Inhibitor
PARP is an enzyme that involved in a number of cellular processes such as DNA repair, and programmed cell death. The PARP family comprises 17 members. They have all very different structures and functions in the cell. Importantly, the main role is to detect and signal single-strand DNA breaks...
Sitravatinib (MGCD516) is an Orally Bioavailable RTK Inhibitor with PD-1 Blockade Activity
Sarcomas are rare but highly aggressive mesenchymal tumors. Mutation and overexpression of many receptor tyrosine kinases (RTKs) including c-Met, PDGFR, c-Kit and IGF1-R drive defective signaling pathways in sarcomas. Sitravatinib is a small molecule inhibitor targeting multiple receptor tyrosine kinases involved in driving sarcoma cell growth. Moreover, Sitravatinib significantly...
Lonafarnib is an Orally Active FPTase Inhibitor
Farnesyl transferase (FTase) is a zinc-dependent enzyme, which coordinates a zinc cation on its β subunit at the lip of the active site. FTase has two subunits: a 48kDa α-subunit and a 46kDa β-subunit. And it adds a 15-carbon isoprenoid called a farnesyl group to proteins bearing a CaaX...
Rineterkib is an Orally Active RAF and ERK1/2 Inhibitor
ERK1 and ERK2 are related protein-serine/threonine kinases that participate in the Ras-Raf-MEK-ERK signal transduction cascade. This cascade participates in the regulation of a large variety of processes. It includes cell adhesion, cell cycle progression, cell migration, cell survival, differentiation, metabolism, proliferation, and transcription. MEK1/2 catalyze the phosphorylation of human...
YUM70, a Selective GRP78 Inhibitor, Induces ER Stress-Induced Apoptosis
GRP78 (Glucose-regulated protein, 78 kDa) is a key regulator of endoplasmic reticulum (ER) stress signaling. In this study, researchers describe the discovery of a series of GRP78 inhibitors. YUM70 is an ER stress inducer and kills cells by activating the apoptosis pathway. Especially, YUM70 treatment induces ER stress and...
