Harmane is a benzodiazepine receptor inhibitor (IC₅₀=7 μM), with IC₅₀ values for mACh, Opioid Receptor, MAO-A/B, and α2-adrenergic receptor of 24 μM, 2.8 μM, 0.5 μM, 5 μM, and 18 μM, respectively. Harmane also inhibits haloperidol and serotonin, with IC₅₀ values of 163 μM and 101 μM, respectively. Harmane inhibits the I1 imidazoline receptor (IC₅₀=30 nM) to reduce blood pressure and has antidepressant, anti-anxiety, anticonvulsant, and analgesic effects. Harmane inhibits dopamine biosynthesis by decreasing tyrosine hydroxylase (TH) activity and enhancing L-DOPA-induced cytotoxicity in PC12 cells. Additionally, Harmane can increase the mutagenic effect induced by 2-acetylaminofluorene (AAF) .

Ethyl 3,4-Dihydroxybenzoate-13C3

Ethyl 3,4-Dihydroxybenzoate- ¹³C₃ (Protocatechuic acid ethyl ester- ¹³C₃) is the ¹³C-labeled Ethyl 3,4-dihydroxybenzoate (HY-W016409). Ethyl 3,4-dihydroxybenzoate (Protocatechuic acid ethyl ester) is an orally effective, blood-brain barrier-permeable, competitive prolyl hydroxylase (PHD) inhibitor that inhibits the hydroxylation modification of hypoxia-inducible factor (HIF) by PHD. Ethyl 3,4-dihydroxybenzoate stabilizes HIF-1α by inhibiting PHD, activates downstream pathways to induce autophagy and apoptosis of tumor cells, and regulates inflammatory responses, inhibits the NF-κB pathway, improves vascular permeability, and promotes osteoblast differentiation. Ethyl 3,4-dihydroxybenzoate has anti-tumor, anti-hypoxic injury, and bone metabolism regulation effects. It can also be used in the research of cardiovascular protection (such as reducing myocardial ischemic damage), bone tissue engineering (promoting osteogenesis/inhibiting osteoclast differentiation), and prevention and treatment of high-altitude cerebral edema .

Harman-d3

Harman-d₃ is deuterium labeled Harmane. Harmane is a benzodiazepine receptor inhibitor (IC₅₀=7 μM), with IC₅₀ values for mACh, Opioid Receptor, MAO-A/B, and α2-adrenergic receptor of 24 μM, 2.8 μM, 0.5 μM, 5 μM, and 18 μM, respectively. Harmane also inhibits haloperidol and serotonin, with IC₅₀ values of 163 μM and 101 μM, respectively. Harmane inhibits the I1 imidazoline receptor (IC₅₀=30 nM) to reduce blood pressure and has antidepressant, anti-anxiety, anticonvulsant, and analgesic effects. Harmane inhibits dopamine biosynthesis by decreasing tyrosine hydroxylase (TH) activity and enhancing L-DOPA-induced cytotoxicity in PC12 cells.

SR11237	RAR/RXR Tyrosine Hydroxylase	Neurological Disease Inflammation/Immunology
SR11237 GMP is SR11237 (HY-107413) produced by using GMP guidelines. GMP small molecules works appropriately as an auxiliary reagent for cell therapy manufacture. SR11237 is a RXR activator and lipid metabolism regulator that promotes the differentiation of induced neural stem cells into dopaminergic (TH-positive) neurons. SR11237 induces transcriptional regulation of lipogenic genes and cholesterol transporters, increases glycosaminoglycan release, and elevates total cellular triglyceride levels. SR11237 promotes heterodimerization of RXR with Nurr1, thereby enhancing tyrosine hydroxylase expression and facilitating dopamine release. SR11237 produces a synergistic effect when used in combination with bFGF/EGF. SR11237 is mainly used in studies related to osteoarthritis and Parkinson's disease .
