Product Overview

Stemolecule LY411575 is a selective, cell permeable, small molecule gamma secretase inhibitor which blocks Notch activation1. Notch signaling is a pathway known to regulate both differentiation and proliferation of cells in diverse adult tissues. LY411575 has been shown to promote goblet cell differentiation in mice intestine. Concurrently, LY411575 inhibits cell proliferation2. LY411575 has also been observed to promote neural differentiation of mouse embryonic stem (ES) cells3

White powder


For a 10 mM concentrated stock solution of LY411575, reconstitute the compound by adding 1.04 ml of DMSO to the entire contents of the vial. If precipitate is observed, warm the solution to 37°C for 2 to 5 minutes. For cell culture, the media should be prewarmed prior to adding the reconstituted compound. Note: for most cells, the maximum tolerance to DMSO is less than 0.5%. This molecule is soluble in DMSO at 100 mM.

Storage and Stability

Store powder at 4°C protected from light. Following reconstitution, store aliquots at -20°C. Stock solutions are stable for 6 months when stored as directed.

Quality Control

The purity of LY411575 was determined by HPLC analysis. The accurate mass was determined by mass spectrometry. Cellular toxicity of LY411575 was tested on mouse embryonic stem cells.

Matthew Mehana Hello. I recently just found out about compound "LY-411575". I've had slight hearing loss for the past 2 years and if feels like my ears are "clogged" due to all the frequency loss. Is this new compound a cure for hearing loss? And can it be taken my humans yet? Please reply, I haven't been myself since it suddenly happened. I hope this is at least a good start?
