Applications CK 1827452 is a promising new drug in systolic heart failure. It accelerates the transition of myosin into the force-generating state without affecting cardiac myocyte calcium homeostasis. CK 1827452 increases cardiac function by increasing the duration of ejection without changing the rates of contraction. References Meijs, M. et al.: Eur. J. Heart. Fail., 14, 232 (2012); Malik, F. et al.: J. Mol. Cell. Card., 51, 454 (2011)

Stability Hygroscopic and Moisture Sensitive Applications Bortezomib is the first proteasome inhibitor to be approved by the US FDA for multiple myeloma, a blood cancer. A reversible inhibitor of the 26S proteasome-a barrel-shaped multiprotein particle found in the nucleus and cytosol of all eukaryotic cells. Targets the ubiquitin-proteasome pathway. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Nawrocki, S.T., et al: Cancer Research, 65, 11510 (2005); Drahl C.: Chem. and Eng. News, 87, 41 (2009);

Applications Colistin B Sulfate Salt is sulfate salt form of Colistin B which is used as an antibiotic in the treatment of infectious diseases resulting from multi-drug resistant (MDR) gram-negative bacteria.
