ML SA1 is a selective TRPML agonist with an EC50 value of 15.3μM [1]. The ML SA1 exhibits remarkable antiviral activity, significantly inhibiting the RNA of dengue virus (DENV) and zika virus (ZIKV), with IC50 values of 8.93μM and 52.99μM, respectively[2]. ML SA1 inhibits viral infection by down-regulating the expression of TRPML2 and TRPML3, negatively regulating the expression of the late endosome marker Rab7, and promoting the transport of vesicles from the late endosome to the lysosome[3]. The ML SA1 has been widely used to rescue Alzheimer-related alterations of the endosomal-autophagic-lysosomal system [4].
In vitro, ML SA1 treatment (30μM) for 24 hours significantly increased the expression of LC3-II in NRK-52E cells and promoted autophagy of the cells[5]. Treatment with 25μM ML SA1 for 18 hours significantly reduced the α-synuclein aggregates and protein levels in HEK293T cells[6]. 10μM of ML SA1 pretreatment for 1 hour significantly reduced the production of cleaved caspase-3 in mouse hippocampal neuronal cells induced by oxygen-glucose deprivation (OGD), and decreased the apoptosis rate of neurons[7].
In vivo, ML SA1 treatment via subretinal space injection at a single dose 10μM (5μl) significantly improved retinal structure and the outer nuclear layer, and reduced the apoptosis of photoreceptor cells in a rat model of retinal detachment (RD) [8].

| Cell experiment [1]: | |
Cell lines | NRK-52E cells |
Preparation Method | NRK-52E cells were grown in DMEM medium with 10% (v/v) fetal bovine serum (FBS), 0.2mM glutamine, 100U/ml penicillin, and 100μg/ml streptomycin at 37°C in 5% CO2/atmosphere. Cells (2×105 cells/ml) were seeded onto 24-well plates allowed to adhere in a 5% CO2 incubator at 37°C overnight. Cells were treated with different concentrations of ML SA1 (0, 3, 10, and 30µM) for 24h. The expression of autophagy marker LC3-II was evaluated. |
Reaction Conditions | 0, 3, 10, and 30µM; 24h |
Applications | ML SA1 treatment significantly enhanced the LC3-II levels in NRK-52E cells in a dose-dependent manner. |
| Animal experiment [2]: | |
Animal models | Sprague-Dawley rats |
Preparation Method | Male Sprague-Dawley rats (250-300g) were housed singly in a standard environment with food and water ad libitum. The rats were anaesthetized by intraperitoneal injection of chloral hydrate 10%; 0.3ml/100g), and 0.5% tropicamide drops were used to dilate the pupils. Then, the eye surface was anaesthetized with 0.5% hydrochloride, and the conjunctival sac was rinsed using levofloxacin before the surgery. A 30-G needle was inserted into the subretinal space at a 45° angle from 2mm behind the limbus of the cornea through the sclera and vitreous cavity, and 50μl of 10% sodium hyaluronate was injected into the subretinal space to establish the RD model. For each animal, the right eye was used to develop the RD model, and the left eye served as a normal control. Any animal that experienced surgical complications was excluded from the study. After the RD model was established, a microinjector was used to carry out injections. ML SA1 was diluted in DMSO, and DMSO (5μl; 0.1%) and ML SA1 (5μl; 10μM) were gently injected into the subretinal space of RD model rats in the DMSO group and ML SA1 group, respectively. |
Dosage form | 10µM (5µl) for once; subretinal space injection |
Applications | ML SA1 treatment significantly improved retinal structure and the outer nuclear layer, and reduced the apoptosis of photoreceptor cells in RD rats. |
