Biological Activity

Description

ML355 is a potent and selective inhibitor of human 12-Lipoxygenase with an IC50 of 290 nM and shows excellent selectivity over related lipoxygenases and cyclooxygenases.

Targets

12-LOX ^[1]

In vitro
In vitro	ML355 displays nM potency against 12-LOX and excellent selectivity over related lipoxygenases and cyclooxygenases^[1].
Cell Research	Cell lines	U87 cells
	Concentrations	10 µM
	Incubation Time	24 h
	Method	Cells were treated with indicated concentration of drug for 24 h.

In Vivo
In vivo	In vivo PK studies where ML355 is administered as a solution via IV (3mpk) and PO (30mpk) demonstrated that ML355 is orally bioavailable (%F = 20) with good half-life (T1/2 = 2.9 hours). At 30 mpk dosing, ML355 achieves a Cmax of over 135 times the in vitro IC50 and remains over IC50 value for over 12 hours. The compound has low clearance (3.4 mL/min/kg) and good overall exposure (AUCinf) of 38 µM. Although, the volume of distribution (VD) observed is low (0.55 L/kg), the rest of the PK profiling results suggest a reasonable distribution between tissue and blood^[1].
Animal Research	Animal Models	C57BL/6 mice
	Dosages	15 or 30 mg/kg
	Administration	p.o.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
