Description of ML351

ML351 is a selective 15-lipoxygenase-1 (15-LOX-1; 12/15-LOX) inhibitor with an IC50 of 200nM[1]. 15-LOX-1 is a member of the lipid oxidase family that can trigger phospholipid peroxidation in the plasma membrane. By inhibiting 15-LOX-1, ML351 can reduce the production of harmful oxidative products in cells[2].

In vitro, HT-22 cells treated with ML351 (0-10μM) dose-dependently reversed glutamate-induced cell death[1]. ML351 (10μM) treatment of peritoneal macrophages (PMφ) cells for 2 h inhibited the inflammatory response induced by Kdo2-Lipid A and suppressed the mRNA expression of 12/15LOX and inducible nitric oxide synthase (iNOS )[3].

In vivo, ML351 (50 mg/kg) treated with acute heart failure mice by subcutaneous injection significantly reduced myocardial infarction size on days 1 and 5, increased CD11b expression, and reduced inflammatory responses in the heart and spleen [3]. ML351 (24 mg/kg) treated with intraperitoneal injection in non-obese diabetic (NOD) mice for 8 weeks reduced blood glucose levels, reduced oxidative stress markers in pancreatic β cells, and increased antioxidant enzyme levels [4]. ML351 (50μM/kg) treated with intraperitoneal injection in rats undergoing orthodontic treatment for 14 days strongly inhibited orthodontic-induced root resorption (OIRR) and suppressed the appearance of osteoclasts and odontoclasts [5].

Protocol of ML351

Cell experiment [1]:

Cell lines

Peritoneal macrophage (PMϕ)

Preparation method

PMϕ were isolated from male C57BL/6 mice after injection of cold media (DMEM with 10% heat inactivated FBS, 1% antibiotic/antimycotic) into the peritoneal cavity. After 4–6 h at 37°C, 5% CO2 in the incubator, cells are well attached and ready for experiments. ML351 (10μM) was added in direct contact to the cells for 2 h.

Reaction Conditions

10 μM ; 2 h

Applications

ML351 decreased 12LOX gene expression (0.52 fold) and 15LOX gene expression (0.73 fold) with no change in 5LOX expression compared with the control group.

Animal experiment [2]:

Animal models

NOD/ShiLTJ (NOD) mice

Preparation method

Six-week-old NOD mice were injected intraperitoneally with vehicle or 24 mg/kg ML351 daily for 2 weeks.

Dosage form

24 mg/kg; i.p.

Applications

Treatment of NOD mice with ML351 led to improved glycemic control and significantly reduced insulitis.
