BRYOSTATIN 1 Usage And Synthesis

Uses

Bryostatin 1 has been used to study its effects on spontaneous Crohn′s disease (CD) like colitis in?mice. It has also been used to study its effects as an anthelmintic drug on adult Syphacia muris infection in rats.

Definition

ChEBI: A member of the class of bryostatins that is (17E)-2-oxooxacyclohexacos-17-ene which is substituted by hydroxy groups at positions 4, 10, and 20; an acetoxy group at position 8; methyl groups at positions 9, 9, 18, and 19; 2-methoxy-2-oxoe hylidene groups at positions 14 and 24; an (E,E)-octa-2,4-dienoyloxy group at position 21; and with oxygen bridges linking positions 6 to 10, 12 to 16, and 20 to 24. It is one of the most abundant member of the class of br ostatins.

Biological Activity

Protein kinase C (PKC) activator that binds with high affinity (K i = 1.35 nM). Initially activates and subsequently induces downregulation of PKC isozymes. Sensitizes tumor cells to cytotoxic effects of anticancer agents.

Biochem/physiol Actions

Bryostatin 1 (Bry1) is a macrocyclic lactone. This synaptogenic compound is obtained from the marine bryozoan?Bugula neritina. Bry1 is capable of reversing synaptic loss. It can enable synaptic maturation in animal models with several neurological disorders. It possesses antidepressant activity, when administered intracebroventricularly. Bry1 is known to participate in protecting cell tight junctions (TJs), anti-inflammatory functions and immune regulation.

storage

Store at -20°C
