ANISOMYCIN

Description

Anisomycin (22862-76-6) activates JNK/SAPKs and reduces c-fos and c-jun. Protein synthesis inhibitor. Anisomycin induces apoptosis and sensitizes cells to anoikis. Cell permeable.

Chemical properties

Crystalline

The Uses of ANISOMYCIN

Anisomycin is a phenylmethylenepyrrolidine first isolated from Streptomyces griseolus in 1954 as an antiprotozoan with antifungal activity. Anisomycin is an inhibitor of protein synthesis by binding to the 60S ribosomal subunit. Interestingly, anisomycin has found use for the induction of amnesia in animal models. More recently, anisomycin has been demonstrated to induce apoptosis, to be a selective signalling agonist, to activate mitogen-activated protein (MAP) kinases and to be immunomodulatory via its action on T cells.

The Uses of ANISOMYCIN

It is applied as an antiparasitic agent and antineoplastic agent. It acts as a protein synthesis inhibitor (blocks translation), potent activator of stress-activated protein kinases (JNK/SAPK) and p38 MAP kinase. It also scts as a potent signaling agonist to selectively elicit homologous desensitization of immediate early gene induction (c-fos, fosB, c-jun, junB and junD). Activates mitogen-activated protein (MAP) kinases (JNK/SAPK and p38/RK).

What are the applications of Application

Anisomycin is activator of JNK (c-Jun N-terminal kinases) and p38

Definition

ChEBI: An antibiotic isolated from various Streptomyces species. It interferes with protein and DNA synthesis by inhibiting peptidyl transferase or the 80S ribosome system.

Biological Activity

Protein synthesis inhibitor (blocks translation). Potent activator of stress-activated protein kinases (JNK/SAPK) and p38 MAP kinase. Acts as a potent signaling agonist to selectively elicit homologous desensitization of immediate early gene induction (c-fos, fosB, c-jun, junB and junD).

Biochem/physiol Actions

Antibiotic isolated from Streptomyces griseolus that inhibits protein synthesis. Acts by inhibiting peptidyl transferase activity in eukaryote ribosomes. Reported to induce apoptosis in a variety of cells including promyelocytic leukemia cells, Jurkat cells, ventricular myocytes, and colon adenocarcinoma cells. Initiates intracellular signals and immediate early gene induction. Selective signaling agonist. Potent Jun-NH2 terminal kinase (JNK) agonist. Activates mitogen-activated protein (MAP) kinases (JNK/SAPK and p38/RK). Antiprotozoal agent.

Safety Profile

Poison by ingestion,intraperitoneal, subcutaneous, and intravenous routes.When heated to decomposition it emits toxic fumes ofNOx.
