Leucic acid α-Hydroxyisocaproic acid	Drug Metabolite Hydroxycarboxylic Acid Receptor (HCAR) AMPK ERK	Metabolic Disease Inflammation/Immunology
Leucic acid (α-Hydroxyisocaproic acid) is an orally active end-product of the microbial metabolism of leucine. Leucic acid can bind to *HCAR2, alters AMPK* and *ERK1/2* phosphorylation status, suppresses lipid synthesis, promotes catabolism, reduces adiposity, enhances lean mass and exercise capacity. Leucic acid suppresses pro-inflammatory cytokine secretion, inflammation-related gene mRNA expression. Leucic acid decreases basal protein synthesis, attenuates myotube atrophy. Leucic acid can be used for the research of obesity ^[2] .

HY-107581

MK-1903 1 Publications Verification	GPR109A MMP	Metabolic Disease Inflammation/Immunology
MK-1903 is an orally active full agonist of *GPR109a/HCAR2, with an EC₅₀* of 12.9 nM. MK-1903 activates antilipolytic and vasodilatory pathways, reduces plasma free fatty acid levels, and induces skin flushing. MK-1903 stimulates the expression of *HCAR2* protein and regulates the inflammatory response of microglia. MK-1903 prevents the enhanced firing activity of spinal nociceptive neurons. MK-1903 triggers the release of MMP-9 and the formation of NET. MK-1903 can be used in the research of dyslipidemia and neuroinflammation-based central nervous system diseases ^[2] .

HY-156025

HCAR2 agonist 1	Hydroxycarboxylic Acid Receptor (HCAR)	Inflammation/Immunology
HCAR2 agonist 1 (Compound 9n) is a G_i protein-biased allosteric modulator of *HCAR2. HCAR2* agonist 1 activates the G_i protein signaling pathway. HCAR2 agonist 1 shows anti-inflammatory effect, and reduces mRNA level of pro-inflammatory cytokine (TNF-α, IL-1β, IL-6, and MCP-1). HCAR2 agonist 1 enhances anti-inflammatory effects of orthosteric agonists in the mouse model of colitis .
