Arimoclomol (INN; originally codenamed BRX-345, which is a citrate salt formulation of BRX-220) is an experimental drug developed by a biopharmaceutical company CytRx Corporation. In 2011 the worldwide rights to arimoclomol were bought by Danish biotech company Orphazyme ApS. The European Medicines Agency (EMA) and U.S. Food & Drug Administration (FDA) granted orphan drug designation to arimoclomol as a potential treatment for Niemann-Pick type C in 2014 and 2015 respectively. Arimoclomol is believed to function by stimulating a normal cellular protein repair pathway through the activation of molecular chaperones. Since damaged proteins, called aggregates, are thought to play a role in many diseases, CytRx believes that arimoclomol could treat a broad range of diseases.

Route of Administration: Oral

In Vitro Use Guide

Human SH-SY5Y cells were used for activity evaluation. For quantitative analysis, of cell viability by fluorescence microscopy, cells were harvested at the indicated time point after single or co-application of celastrol and Arimoclomol (50 or 250 mkM). An equal volume of cell suspension was mixed with 0.4 % trypan blue (T10282; Life Technologies) and incubated for 2 min. The cell suspension was loaded into a disposable Countess® cell counting chamber slide, and the percent of cells stained by trypan blue was quantified using a Countess® automated cell counter.
