Biological Activity

Description	Palmitic acid (Hexadecanoic acid, Cetylic acid) is the most common saturated fatty acid found in animals, plants and microorganisms with anti-tumor activity.

In vitro
In vitro	Palmitic acid (PA) binds TLR4 via the adaptor protein MD2 and that the TLR4 signal induced by PA stimulates dendritic cells activation and maturation accompanied by a robust IL-1β response. Palmitic acid is a TLR4/MD-2 ligand. It exerts pro-inflammatory activity through TLR4^[1].
Cell Research	Cell lines	The insulinoma cell line INS-1
	Concentrations	250 μmol/L
	Incubation Time	24 or 48 h
	Method	The INS-1 cells are seeded onto 96-well plates at 4,000 cells/well with 10% BSA and incubated with T0901317 (10 μmol/L), palmitic acid (250 μmol/L), a combination of T0901317 and palmitic acid or PBS (mock control) for 24 or 48 h. After the treatment incubation, 20 μl of MTT solution (5 mg/mL MTT in PBS, pH 7.4) are added to each well, followed by incubation at 37°C for 4 h. The supernatants are removed from the wells and DMSO (15 μl/well) is added to dissolve the crystals. The optical density at a wavelength of 490 nm is measured using a microplate reader.

In Vivo
In vivo	In a dose-dependent fashion, palmitic acid rapidly reduces mouse locomotor activity by a mechanism that did not rely on TLR4, MyD88, IL-1, IL-6 or TNFα but is dependent on fatty acid chain length. Palmitic acid induces anxiety-like behavior in mice while increasing amygdala-based serotonin metabolism^[2].
Animal Research	Animal Models	C57BL/6J mice
	Dosages	0.3, 3, and 30 μmol/mouse
	Administration	i.p.

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.
