 Use of (1S,2S)-ML-SI3


(1S,2S)-ML-SI3 is the trans-isomer of ML-SI3, a TRPML inhibitor. The (-)-isomer is a potent inhibitor of TRPML1 and TRPML2 (IC50=1.6 μM/2.3 μM) and a weak inhibitor of TRPML3 (IC50=12.5 μM), whereas the (+)-enantiomer is an inhibitor on TRPML1 (IC50=5.9 μM), but an activator on TRPML 2 and 3[1].
