Molecular Weight 415.79 CAS No. 899713-86-1
Solubility (25°C)* In vitro DMSO 30 mg/mL (72.15 mM)
Ethanol 21 mg/mL (50.5 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5% DMSO 95% Corn oil
0.75mg/ml Taking the 1 mL working solution as an example, add 50 μL of 15 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
0.75mg/ml Taking the 1 mL working solution as an example, add 50 μL of 15 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description ML348 (GNF-Pf-1127) is a potent and selective APT1 (Acyl protein thioesterase 1)/lysophospholipase 1 (LYPLA1) inhibitor with Ki values of 280 nM and >10 μM for APT1 and APT2, respectively.
Targets
APT1 [1]
280 nM(Ki)
In vitro

ML348 increases brain palmitoylation and inhibits the palmitate-removing enzyme acyl-protein thioesterase 1 (APT1), restores axonal transport, synapse homeostasis, and survival signaling to wild-type levels without toxicity, also increases BDNF trafficking in human HD induced pluripotent stem cell-derived cortical neurons.[2]
In vivo

In HD knock-in mice, ML348 efficiently crosses the blood-brain barrier to restore palmitoylation levels and reverse neuropathology, locomotor deficits, and anxio-depressive behaviors.[2]

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    STHdh cells, human HD patient iPSC-derived cortical neurons, CAG140 neurons

  • Concentrations

    10, 1 μM

  • Incubation Time

    1, 4h

  • Method

    ML348, palmostatin B, and ML349 are diluted in 100% dimethyl sulfoxide (DMSO) for primary concentration. For STHdh cells and immunofluorescence of neurons plated on coverslips, we administered acute treatment with 10 μM for 1 hour before and during the acquisition time. For the fractionation experiments, we plated cortical neurons on 10-cm dishes and we treated cells for 4 hours with 1 μM ML348 before lysis. For neurons within microchambers, 1 μM ML348 is administered within each compartment of the microfluidic device beginning on days in vitro (DIV)2 and continuing daily until DIV12, while for BDNF pHluorin analysis, compartments are treated for 4 hours with 1 μM ML348 before acquisition.
