HY-W744699

Larixol (+)-Larixol	Src ERK Akt	Inflammation/Immunology
Larixol is an fMLP inhibitor and also inhibits Src kinase, ERK1/2, p38 and AKT phosphorylation signals in immune regulation. Larixol can interfere with the interaction between the βγ subunit of the fMLP receptor Gi protein and its downstream molecules, thereby inhibiting fMLP-induced respiratory burst. Larixol inhibits fMLP (0.1 μM)-induced superoxide anion production (IC₅₀: 1.98 μM), cathepsin G release (IC₅₀: 2.76 μM), and chemotaxis. Larixol improves neutrophil hyperactivation and reduces inflammation or tissue damage. A series of Larixol derivatives were found to have inhibitory effects on FSGS-related TRPC6 functional mutants .

HY-156025

HCAR2 agonist 1	Others	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 .

HY-110202

MRS5698	Adenosine Receptor	Neurological Disease Inflammation/Immunology
MRS5698 is a selective G_i protein-coupled A₃ adenosine receptor (A₃AR) agonist, with K_is of approximately 3 nM for human and mouse A₃AR, respectively. MRS5698 can be used for the research of pain and psoriasis .

HY-112779

Pertussis Toxin	Others	Infection
Pertussis Toxin is a protein-based AB₅-type exotoxin produced by the bacterium Bordetella pertussis, which causes whooping cough. Pertussis Toxin inhibits *G protein-coupled receptor (GPR)* signaling through Gi proteins .

HY-150524

UDP-Galactose	Endogenous Metabolite P2Y Receptor	Metabolic Disease
UDP-Galactose is a monosaccharide involved in nucleotide sugar metabolism. UDP-Galactose and its derivatives act as a natural agonist for G_i protein-conjugated P2Y₁₄ receptors in the immune system (IC₅₀=0.67 μM, hP2Y₁₄) .

HY-107024

Osteogenic Growth Peptide (10-14) OGP(10-14); Historphin	Src	Others
Osteogenic Growth Peptide (10-14) (OGP(10-14)), the C-terminal truncated pentapeptide of osteogenic growth peptide (OGP), retains the full OGP-like activity. Osteogenic Growth Peptide (10-14) is responsible for the binding to the OGP receptor and activates an intracellular Gi-protein-MAP kinase signaling pathway. Osteogenic Growth Peptide (10-14) is a potent mitogen and stimulator of osteogenesis and hematopoiesis. Osteogenic Growth Peptide (10-14) acts as a Src inhibitor .

Isomaltulose monohydrate	Formyl Peptide Receptor (FPR) Src ERK Akt p38 MAPK	Others
Isomaltulose monohydrate is a fMLP inhibitor and also inhibits Src kinase, ERK1/2, p38 and AKT phosphorylation signals in immune regulation. Isomaltulose monohydrate can interfere with the interaction between the βγ subunit of the fMLP receptor Gi protein and its downstream molecules, thereby inhibiting fMLP-induced respiratory burst. Isomaltulose monohydrate inhibits fMLP (0.1 μM)-induced superoxide anion production (IC₅₀: 1.98 μM) , cathepsin G release (IC< sub>50: 2.76 μM) and chemotaxis. Isomaltulose monohydrate can improve excessive activation of neutrophils and reduce inflammation or tissue damage. A series of derivatives of Isomaltulose monohydrate are found to have inhibitory effects on FSGS-related TRPC6 functional mutants .
