Apexbio Technology LLC Chlorprothixene (hydrochloride) 6469-93-8 10g
Chlorprothixene hydrochloride (CAS 6469-93-8) is a small-molecule antagonist targeting dopamine (D1 D2 D3 D5) and histamine H1 receptors It modulates neurotransmission by blocking these receptors thereby regulating dopaminergic and histaminergic pathways Chlorprothixene hydrochloride exerts its biological activity primarily through receptor antagonism In in vitro studies it demonstrates nanomolar affinity with Ki values of 18 nM (D1) 2 96 nM (D2) 4 56 nM (D3) 9 nM (D5) and 3 75 nM (H1) Additionally it reduces SARS-CoV viral replication (IC50 13 0 18 5 M depending on strain) Based on these pharmacological properties chlorprothixene hydrochloride holds research potential in antipsychotic therapy antiviral investigation and modulation of inflammation in cystic fibrosis models
Apexbio Technology LLC Mefenamic Acid 61-68-7 10g
Mefenamic acid (CAS 61-68-7) is a non-steroidal anti-inflammatory compound that acts by inhibiting cyclooxygenase (COX) enzymes leading to decreased synthesis of prostaglandins involved in inflammation and pain signaling It is extensively studied for its ability to modulate inflammatory pathways and is commonly utilized as a pharmacological tool in research focused on pain mechanisms inflammatory responses and prostaglandin-mediated processes Mefenamic acid is often employed in in vitro and in vivo models to evaluate the effects of COX inhibition on physiological and pathological conditions
Apexbio Technology LLC Diclofenac 15307-86-5 10g
Diclofenac (CAS 15307-86-5) is a phenylacetic acid derivative classified as a non-steroidal anti-inflammatory drug (NSAID) It exerts its biological activity by inhibiting cyclooxygenase (COX)-1 and COX-2 enzymes thereby suppressing prostaglandin synthesis that mediates inflammation and pain signaling Structurally the incorporation of two ortho chlorine atoms on the phenyl ring increases molecular rigidity which has been associated with enhanced potency Diclofenac is widely used in research to study inflammatory pathways pain mechanisms and as a reference compound in the evaluation of cyclooxygenase inhibition and potential gastrointestinal protective strategies in combination therapies
Apexbio Technology LLC Naproxen Sodium 26159-34-2 10g
Naproxen sodium (CAS 26159-34-2) is a non-selective cyclooxygenase (COX) inhibitor that suppresses both COX-1 and COX-2 activity In vitro it exhibits IC50 values of 35 48 mol/L for COX-1 and 64 62 mol/L for COX-2 Naproxen sodium influences satellite cell biology by affecting proliferation fusion and differentiation particularly when both COX-1 and COX-2 are inhibited In HCA-7 colon cancer cells naproxen reduces cell viability with an IC50 of 1 45 0 07 M after 48-hour exposure Clinically repeated dosing in volunteers results in substantial inhibition of COX isoforms while research in menstrual migraine models shows significant reductions in headache parameters
Apexbio Technology LLC Betaine hydrochloride 590-46-5 10g
Betaine hydrochloride (CAS 590-46-5) is a quaternary ammonium compound that serves as a methyl group donor in cellular metabolism notably participating in the methionine-homocysteine cycle to modulate homocysteine levels Extracted from natural sources such as wolfberry and Achyranthes this molecule is soluble in water and ethanol facilitating its use in various assay systems Betaine hydrochloride is frequently employed in biomedical research to investigate metabolic regulation methylation processes and osmoregulatory mechanisms The compound should be stored tightly sealed in cool dry conditions to maintain stability for experimental applications
