Overview - LPI and 2-ALPI

Description of LPI and 2-ALPI

LPI is a proposed endogenous ligand/agonist for GPR55 (Roberto Piñeiro et al. 2012)

2-ALPI is a proposed endogenous ligand/agonist for GPR55 (Saori Oka et al. 2009)

Other Names:

Lysophosphatidylinositol and 2-arachidonoyl lysophosphatidylinositol
LPI: L-alpha-lysophosphatidylinositol; L-α-lysophosphatidylinositol

LPI IUPAC Name: [(2S)-2-hydroxy-3-[hydroxy-[(2R,3S,5R,6R)-2,3,4,5,6-pentahydroxycyclohexyl]oxyphosphoryl]oxypropyl] acetate

LPI Molecular Formula: C11H21O12P

2-ALPI: 2-arachidonoyl-LPI; 2-arachidonoyl-lysophosphatidylinositol; 2-arachidonoyl-sn-glycero-3-phospho-D-myo-inositol 4,5-bisphosphate

2-ALPI IUPAC Name: [(1R,2S,3R,4R,5S,6R)-2,3,5-trihydroxy-4-[[(2R)-3-hydroxy-2-[(5Z,8Z,11Z,14Z)-icosa-5,8,11,14-tetraenoyl]oxypropoxy]-oxidophosphoryl]oxy-6-phosphonatooxycyclohexyl] phosphate

2-ALPI Molecular Formula: C29H46O18P3-5

LPI and 2-ALPI Properties and Effects

The LPI/GPR55 axis may play a negative role in the pathology of:
• May worsen metabolic disorders (e.g., obesity, diabetes, inflammation)
• May worsen developments and metastasis of certain cancer (e.g., breast cancer, colon cancer, uterine/endometrial cancer)
• May worsen non-alcoholic steatosis & steatohepatitis
• May worsen myocardial ischemia/reperfusion injury via a GPR55/ROCK-dependent pathway
• Inflammation (mixed results with some studies suggesting pro- vs anti-inflammatory effects)

Inhibitors of LPI: Δ9-tetrahydrocannabivarin, cannabidivarin, and cannabigerovarin are inhibitors of LPI (Sharon Anavi-Goffer et al. 2012); CBD (E Ryberg et al. 2007)

LPI and 2-ALPI Receptor Binding

Endocannabinoidome (eBCome)
• Both LPI and 2-LPI are proposed endogenous ligand/agonist for GPR55.
• LPI activates TRPV2 (Kazuki Harada et al. 2017)
