Description of ML 348

ML 348 is a selective and reversible lysophospholipase 1 (LYPLA1) inhibitor with an IC50 of approximately 210nM, exhibiting 14-fold selectivity for LYPLA1 over LYPLA2[1-2]. ML 348 can be used to study protein palmitoylation and the biological functions of LYPLA1, and it significantly inhibits enzymatic activity in heart, lung, and kidney tissues[3-4].

In vitro, pretreatment of porcine alveolar macrophages (PAMs) with ML 348 (1μM) for 24–36 hours, followed by infection with porcine reproductive and respiratory syndrome virus (PRRSV-2; MOI=0.1), significantly suppressed viral ORF7 mRNA transcription and nucleocapsid protein (N protein) expression, while reducing viral titers[5]. Pretreatment of NRAS-mutant melanoma cells with ML 348 (≤12.5μM) for 6 hours did not significantly affect cell viability and did not markedly inhibit phosphorylation of the NRAS downstream signaling pathways ERK and AKT[6].

In vivo, chronic subcutaneous infusion of ML 348 (0.3mg/kg) for 28 days in 7-month-old symptomatic CAG140 Huntington's disease knock-in mice effectively crossed the blood-brain barrier, significantly improved motor coordination and alleviated anxiety-depressive-like behaviors, and reversed neuropathological changes[7]. Oral administration of ML 348 (70mg/kg) for 90 days in 12-month-old symptomatic 3KL α-synucleinopathy model mice significantly enhanced motor coordination, spatial memory, and long-term memory, and restored hippocampal synaptic plasticity[8].

Protocol of ML 348

Cell experiment [1]:

Cell lines

NRAS mutant melanoma cells

Preparation Method

Cells were treated with ML 348 (≤12.5µM) for 6 hours to assess acute signaling changes.

Reaction Conditions

≤12.5μM; 6h

Applications

ML 348 caused minor increases in AKT phosphorylation but did not alter ERK or S6 phosphorylation, indicating no biologically significant impact on NRAS downstream signaling pathways.

Animal experiment [2]:

Animal models

CAG140 knock-in HD mice (Huntington disease model)

Preparation Method

Mice were subcutaneously infused with ML 348 (0.3mg/kg/day) via Alzet osmotic pumps for 28 days. Behavioral tests and tissue analyses were conducted during and after treatment.

Dosage form

0.3mg/kg; subcutaneous infusion; Chronic administration; Daily for 28 days.

Applications

ML 348 treatment restored motor coordination in the horizontal ladder test (reduced error rate and crossing time), improved balance in rotarod tests, and alleviated anxio-depressive behaviors in novelty-suppressed feeding tests. ML 348 increased brain palmitoylation levels, reduced mutant huntingtin (mHTT) nuclear accumulation, and restored corticostriatal synapse density.
