Allgemeine Beschreibung

Chemical structure: aureolic acid

Anwendung

Chromomycin A3 from Streptomyces griseus has been used as a reagent in flow sorting. It has also been used to stain spermatozoa to evaluate the sperm nuclear chromatin integrity.

Biochem./physiol. Wirkung

Chromomycin A3 from Streptomyces griseus is an antibiotic exhibiting anti-bacterial, anti-fungal and antitumor activities. It serves as a fluorescent DNA stain. It is useful for the detection of protamine deficiency in sperm chromatin. The compound blocks macromolecule synthesis by a specific, reversible interaction with DNA in the presence of bivalent metal ions. Binding to DNA minor groove mediates an efficient competitive inhibition of DNA gyrase and significantly affects topoisomerase II activity.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.
