[0001] This application claims the benefit of U.S. Provisional Application Serial No. 63 / 618,506 filed January 8, 2024; which is hereby incorporated by reference in its entirety. BACKGROUND OF THE INVENTION
[0002] TRPML1, also named Mucolipin-1, is a ligand-gated cation channel expressed mostly in intracellular organelles like the late endosome and lysosome of many mammalian cells. This channel is member of the large family of Transient receptor potential (TRP) channels and has, with TRPML2 and TRPML3, two close analogues. Loss-of-function mutations in the gene encoding for TRPML1, the 12,000 base pair gene MCOLN-1 located in human chromosome 19p 13, are the direct cause of Type IV mucolipidosis (MLIV), an autosomal recessive lysosomal storage disease.
[0003] At the molecular level, TRPML1 is a Ca2+-permeable, non-selective cation channel formed of four six-transmembrane spanning proteins each of 580 amino acids. The channel opens upon binding of its endogenous ligand phosphatidylinositol-3,5-bisphosphate (PtdIns(3,5)P2)) to its pore region. Channel activity is modulated by pH and PtdIns(4,5)P2 levels. TRPML1 is an inwardly rectifying channel permeable to different mono- and divalent cations, including Na+, K+, Ca2+, and Fe2+. Its N-terminal API sequence targets the channel to the lysosome while a C-terminal AP2 sequence is responsible for intracellular trafficking and internalization. In addition, TRPML1 has four putative N-linked glycosylation sites in its luminal loop between TM1 and 2. It is reported that TRPML channels can be formed as homo-tetramers (e.g., TRPML1, TRPML2, and TRPML3) but also in some cases as heterotetramers where one channel is composed of different members of the TRPML family.
[0004] TRPML 1 is found in all mammalian tissues with highest expression levels in brain, spleen, liver, kidney, and heart. Expression is found in many cell types, including neurons, myeloid cells, macrophages, microglia, podocytes, and muscle cells. TRPML 1 is involved in function of late endosome / lysosomes (LELs), more specifically in protein trafficking, lysis, and autophagy.
[0005] Lysosomes are organelles filled with hydrolytic enzymes, characterized by a low luminal pH of about 5, a high luminal Ca2+ concentration of about 0.5 mM, and a membrane polarization of about +60 mV.
[0006] TRPML 1 in LELs is reported to be responsible for the formation of transport vesicles, and it is required for the reformation of lysosomes from LEL hybrid organelles and autolysosomes, mostly due to its Ca2+ permeability. TRPML 1 is likely also important for iron release from the lysosome after degradation of iron-binding proteins like cytochrome C. In addition, TRPML 1 is reported to regulate autophagy, probably in an mTOR-independent manner, by promoting TFEB translocation to the nucleus via calcineurin activation. SUMMARY OF THE INVENTION
[0007] In Type IV mucolipidosis (MLIV), the lack of functional TRPML1 leads to severe intellectual disability, motor deficits, retinal degeneration, and systemic symptoms leading to a strongly reduced life expectancy. Cells from MLIV patients show increased autophagosomes, accumulation of lysofuscin, and lipid accumulation in the lysosomes.
[0008] Failure of TRPML1-dependent autophagosome-lysosome fusion is also thought to impair clearance of apoptotic neurons by macrophages and microglia cells. Experimental results suggest involvement of TRPML1 in neurodegenerative diseases like Alzheimer's and amyotrophic lateral sclerosis (ALS). For example, Alzheimer's disease related loss-of-function mutations in presenilin 1 lead to dysregulation of lysosomal Ca2+ homeostasis via TRPML1 modulation. On the other side, overexpression of TRPML1 in rodent Alzheimer's models reduced neuronal apoptosis and rescued memory impairments. Pharmacological activation of TRPML1 showed similar effects, clearing accumulated sphingolipids and Ap peptides from lysosomes. In another study TRPML1 activation was sufficient to upregulate lysosomal exocytosis, rescue defective a-syn secretion and prevent a-syn accumulation in iPSC-derived dopaminergic neurons from patients expressing mutant PARK9. Similarly, TRPML1 activation rescued motor neurons from death and ER stress induced by the cycad neurotoxin beta-methylamino-L-alanine, L-BMAA as a model for ALS.
[0009] Therefore, it is desired to develop TRPML1 modulators to rescue impaired lysosomal function and cellular autophagy in neurodegenerative diseases.
[0010] Despite widespread interest for several years across the pharmaceutical industry, currently described small molecule TRPML1 agonists are not optimized for functional activity and drug like properties. Consequently, there is still an unmet need for compounds which can efficiently stimulate TRPML1 and that can be delivered to the different target organs which are sites of any TRPML1-mediated pathology.

[00252] The final clone for the TRPML1 assay is HEK T-REx / GCaMP6f / TRPMLl. GCaMP6fis a genetically encoded calcium indicator that is stably expressed in this cell line and used as a fluorescent read-out. Assay protocol
[00253] Experiments were performed in 384 MTP format. Cells are seeded at 15000 cells / well in 20 pl / well of Optimem + 0.5% FBS without selection antibiotics. Twenty-four hours later, cells are assayed for the response to various compounds using the Ca2+ sensitive GCaMP6f protein stably expressed in the cells as readout.
[00254] The experiment was performed in a 384-well format according to the following procedures: • 24 h after seeding, the cells were pre-incubated at room temperature for about 10 min. • Started the experiment at the FLIPRTETRA by injecting 10 pL / w of 3x concentrated test compounds and controls in Ca2+ free Tyrode’s buffer. Monitored the kinetic response over a period of 300 seconds. • Final DMSO concentration: 0.5%
[00255] Data from FLIPRTETRA measurements were analyzed with the Genedata Screener0 software. Data analysis Compound % Activity Calculate the Kinetic Response Value (KRV) as: (MAXca- Baseline) / Baseline = [(max(sec5... 290) - mean (sec 1... sec2)) / mean (sec 1... sec2)] Normalize the KRV to the median (<>) of Neutral and Stimulator control wells: r ., x— < NeutralControls > Activity [%] _ Ago = 100 * (——---:-------------------------—---------) < Stimulator Controls > — < NeutralControls > Example B: TFEB Translocation Assay Reporter and Cell line
[00256] Reporter TFEB: the reporter is fused to a sequence of monomeric red fluorescent protein.
[00257] The reporter TFEB have been stably expressed in U2OS cell line and used as read-out. Assay protocol
[00258] Experiments were performed in 384 MTP well format. Cells were seeded in 384-w at a density of 4000 cells / well in 20 pl / well complete growth medium without antibiotics. Twenty-four hours later, cells were treated with compounds and incubated for further 2 hours. Then the cells were imaged and assayed for the response to various compounds using the reporter for TFEB expressed in the cells as readout.
[00259] The experiments were performed in a 384-well format according to the following procedure: • 24 h after seeding, cell culture medium was carefully removed and replaced with 20 pl of Opti-MEM (30’ incubation at 37 °C before compound addition). • Then, cells were incubated with compounds diluted in Opti-MEM + 0.015% Tween 80 at the desired concentration, with the reference molecule (agonist) Torin-1 at a top concentration of 1 pM (max signal), and with the other reference molecule (agonist) MLSA-5 at top concentration of 20 pM for 2 hours at 37°C and 5% CO2. The final percentage of DMSO was 0.5% in all the conditions. • Staining of the nuclei was obtained by incubating the cells with 24 pM / well of Hoechst 3342 in standard Tyrode’s buffer for 15 min at RT. • Then the cells were fixed with PFA 4% for 30 min at RT. • After three washes with standard Tyrode’s buffer, samples were acquired by recording two fluorescence emission channels (DS-red and blue) at 20X magnification and with at least 3 fields of view per well in an Operetta CLS microscope (PerkinElmer). • Image analysis was performed by using Harmony software (PerkinElmer). The image analysis involved the following steps: flat-field illumination correction, nuclei segmentation, cytoplasm segmentation and calculation of intensity fluorescence in the cytosol and nuclei compartments. Measurements of signal intensity ratio (nucleus to cytoplasm) was used to obtain information on the effects of compounds on the TFEB translocation. • Data from image analysis measurements were finally loaded and analyzed for normalization and fitting procedures in Genedata Screener© software.
