staurosporine

Staurosporine (AM-2282) is a protein kinase inhibitor with ATP-competitive and non-selective inhibitory activity (IC50=6/15/2/3/3000 nM) against PKC, PKA, c-Fgr, phosphorylase kinase and TAOK2. Staurosporine also induces apoptosis.

Staurosporine-Boc is a natural product isolated from the actinomycete Streptomyces staurosporeus and functions as a potent, non-selective protein kinase inhibitor. It can inhibit various protein kinases, including protein kinase C (PKC), tyrosine kinase, and serine/threonine kinase. Due to its broad inhibitory profile, Staurosporine-Boc is widely used as a tool compound in biological research, particularly in the study of cell signaling pathways.

K-252a is a protein kinase inhibitor targeting serine-threonine, tyrosine, and CAM kinases. In vitro, it blocks NGF-induced TrkA signalling and neural differentiation, exhibiting antitumour, antibacterial, anti-inflammatory, and neuroprotective activities.

K-252c is a staurosporine analog isolated from Nocardiopsis sp. and is a cell-permeable PKC inhibitor (IC50: 2.45 μM). K-252c also inhibits β-lactamase, chymotrypsin, and malate dehydrogenase. K-252c causes apoptosis in human chronic myelogenous leukemia cancer cells.

Picroside I (6'-Cinnamoylcatalpol), a hepatoprotective agent, is reported to be antimicrobial and used against hepatitis B. It has antioxidant, and anti-inflammatory activities, it may be the valuable anti-invasive drug candidates for cancer therapy by suppressing Collagenases and Gelatinases. Picroside I can enhance basic fibroblast growth factor(bFGF)-, staurosporine- or dbc-mitogen-activated protein (MAP)-induced neurite outgrowth from PC12D cells.

1. Nardosinone has inhibitory effect on Ang II-induced hypertrophy in H9c2 cells, might be mediated by targeting PI3K/Akt and MEK/ERK signaling pathways. 2. Nardosinone could protect against the neuronal injury exposed to OGD, which may be relevant to the

Co-treatment with Tanshinone IIB (TSB) significantly inhibits the DNA laddering, cytotoxicity and apoptosis of rat cortical neurons induced by staurosporine in a concentration-dependent manner; TSB also suppresses the elevated Bax protein and decreased bc

Compound 7, also known as 3′-O-Demethyl-4′-N-demethyl-4′-N-acetyl-4′-epi-staurosporine, serves as an inhibitor of protein kinases, displaying IC50 values of 0.092 μM for PKC-α, 0.26 μM for ROCK, and 0.77 μM for ASK1. Additionally, this compound exhibits significant cytotoxicity towards PC-3 cancer cells, with an IC50 of 0.16 μM [1].
