Triazophos-d₅ (Hostathion 40EC-d₅) is the deuterium labeled Triazophos(HY-B0828) . Triazophos, a non-systemic insecticide and acaricide that acts as an acetylcholinesterase (AChE) inhibitor, covalently and irreversibly binds to the acetylcholine binding site, thus blocking the hydrolysis of acetylcholine and leading to hyperexcitability; it is effective against a variety of soil insects and mites, including aphids, thrips, midges, beetles, Lepidoptera larvae, cutworms, and spider mites in crops such as ornamentals, cotton, rice, maize, soybeans, oil palms, olives, and coffee.

Tolterodine tartrate-d14

Tolterodine tartrate-d₁₄ (Kabi-2234-d₁₄) is deuterium labeled Tolterodine tartrate. Tolterodine ((R)-(+)-Tolterodine) is a mAChR inhibitor and substrate for cytochrome P450 enzymes. Tolterodine competitively binds acetylcholine, reduces sympathetic excitation, and inhibits involuntary bladder muscle contraction. Tolterodine restores the Nrf2/NF-κB signaling pathway, mediates protection against inflammatory response and ferroptosis. Tolterodine ameliorates LPS (HY-D1056)-induced reactive oxygen species production and lipid oxidation. Tolterodine can be used for the research of urinary tract infections and overactive bladder.

Propoxur-d7

Propoxur-d₇ is the deuterium labeled Propoxur. Propoxur is a reversible, competitive, orally active AChE inhibitor that can cross the blood-brain barrier. Propoxur inhibits AChE activity to induce neurotoxicity, while promoting MMP-2 expression and enhancing tumor cell migration and invasion by inducing intracellular ROS generation and activating the ERK/Nrf2 signaling pathway. On the one hand, Propoxur inhibits AChE, leading to acetylcholine accumulation and causing neurological dysfunction; on the other hand, it promotes Nrf2 nuclear translocation through ROS-dependent ERK1/2 phosphorylation, and upregulates MMP-2 and other invasion-related proteins. Propoxur is also a carbamate insecticide used to combat turf, forestry, and household pests .

Arecaidine propargyl ester hydrobromide		Alkynes
Arecaidine propargyl ester hydrobromide is an agonist of M2 muscarinic acetylcholine receptors and has the activity of inhibiting tumor cell proliferation. The application of arecaidine propargyl ester hydrobromide has shown that it can reduce the number of ovarian cancer cells in vitro and induce apoptosis and the production of reactive oxygen species (ROS) at specific concentrations. Arecaidine propargyl ester hydrobromide can also arrest cells at the G2/M phase of the cell cycle and increase the percentage of abnormal mitosis. Arecaidine propargyl ester hydrobromide is more sensitizing to ovarian surface epithelial cells with higher M2 receptor levels than to cancer cells. Arecaidine propargyl ester hydrobromide exhibits the effect of lowering arterial blood pressure when interacting with the cardiovascular system in a natural physiological state, indicating its potential pharmacological application .

Acetyl-L-carnitine hydrochloride 2 Publications Verification O-Acetyl-L-carnitine hydrochloride; ALCAR hydrochloride		Cationic Lipids
Acetyl-L-carnitine (O-Acetyl-L-carnitine; ALCAR) hydrochloride is an orally active mitochondrial energy metabolism regulator and neuroprotectant that can penetrate the blood-brain barrier. Acetyl-L-carnitine hydrochloride selectively enters cells and the brain through the organic cation transporter OCTN2. Acetyl-L-carnitine hydrochloride can participate in fatty acid β-oxidation, promote acetylcholine synthesis, regulate mitochondrial function and inhibit oxidative stress as an acetyl donor. Acetyl-L-carnitine hydrochloride exerts its activity by enhancing energy metabolism, protecting neurons and improving synaptic plasticity. Acetyl-L-carnitine hydrochloride is mainly used in the study of neurodegenerative diseases and metabolic disorder-related diseases such as neonatal hypoxic-ischemic brain damage, Alzheimer's disease, and depression .
