Myristic acid is a 14-carbon saturated fatty acid. It is incorporated into myristoyl coenzyme A (myristoyl-CoA) and transferred by N-myristoyltransferase to the N-terminal glycine of certain proteins either during translation to modify protein activity or post-translationally in apoptotic cells.Formal Name:...

Verruculogen is a tremorgenic mycotoxin isolated from species of Penicillium, Aspergillus, and other fungi. It selectively inhibits the activation of large-conductance calcium-activated potassium channels (KCa1.1/BK) potassium channels by charybdotoxin with a K1/2 value of 170 nM. Verruculogen also promotes the...

1-Deoxysphinganine is an atypical sphingolipid that lacks the C1-hydroxyl group of canonical sphinganine and is formed when serine palmitoyltransferase condenses palmitoyl-CoA with alanine instead of serine during sphingolipid synthesis. Plasma levels of 1-deoxysphinganine are increased in patients with hereditary...

Geldanamycin is a benzoquinone ansamycin antibiotic which binds heat shock protein 90 (Hsp90) and its paralog GRP94, altering their actions. Through its interaction with these chaperones, geldanamycin indirectly affects numerous client proteins with roles in diverse cellular processes, including gene expression,...

SB 218078 is an inhibitor of checkpoint kinase 1 (Chk1) that blocks phosphorylation of cdc25 with an IC50 value of 15 nM. It less potently inhibits cdc2 and PKC (IC50s = 250 and 1,000 nM, respectively) and causes 85% inhibition of PKD1 at 1 µM. SB 218078 releases G2 cell cycle arrest induced by gamma-irradiation or...
