General description
Pentabromopseudilin (PBP) is a potent antibiotic originally isolated from the marine bacterium Pseudomonas bromoutilis. 2 PBP exhibits cytotoxic, antibacterial and phytotoxic activities, including the inhibition of human 12- and 15-lipoxygenases3 and potent inhibition of myosin-dependent processes. 4-5 PBP was identified as a potent inhibitor of the motor activity of vertebrate myosin V with an IC50 value of 1.2μM. 5 PBP inhibits the ATPase activity of myosin by increasing its affinity for ADP, reducing ATP-binding and hydrolysis rates, and through coupling between actin and nucleotide-binding sites in the motor domain. 4 Recently, it was also demonstrated that PBP suppresses TGF-β activity.
Other Notes

[reaction: see text] A regioselective synthesis of propargylamines by the coupling of propargyl alcohols with tosylamines and carbamates catalyzed by an air- and moisture-tolerant rhenium-oxo complex is described. The ability to couple functionalized components allows for convergent approaches to nitrogen-containing

Myosin activity is crucial for many biological functions. Strong links have been established between changes in the activity of specific myosin isoforms and diseases such as cancer, cardiovascular failure, and disorders of sensory organs and the central nervous system. The

We have identified pentabromopseudilin (PBP) as a potent inhibitor of myosin-dependent processes such as isometric tension development and unloaded shortening velocity. PBP-induced reductions in the rate constants for ATP binding, ATP hydrolysis and ADP dissociation extend the time required per
