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 Trimethoprim 738-70-5 10g
Trimethoprim (CAS 738-70-5) is a small-molecule inhibitor targeting bacterial dihydrofolate reductase (DHFR) It is designed to selectively inhibit DHFR thereby disrupting folate metabolism and nucleic acid synthesis in bacteria Trimethoprim exerts its biological activity primarily through competitive inhibition of bacterial DHFR In experimental studies trimethoprim demonstrates inhibitory activity with IC50 values ranging from approximately 5 to 15 nM against bacterial DHFR enzymes Based on these pharmacological properties trimethoprim holds research potential in studies of microbiology urinary tract infections bacterial metabolism folate biosynthesis antimicrobial resistance and in the pharmacological profiling of antibacterial agents
Apexbio Technology LLC Solvent Blue 35 17354-14-2 10g
Solvent Blue 35 (CAS 17354-14-2) is a synthetic lipophilic dye used for selective staining of triglycerides in animal tissue samples It integrates into nonpolar solvents such as alcohols and hydrocarbons to facilitate visualization of neutral lipid components within histological techniques Solvent Blue 35 is applied in laboratory settings for analyzing lipid accumulation distribution and metabolism Based on these properties Solvent Blue 35 holds research potential in the investigation of physiological and pathological lipid storage including fatty liver disease metabolic disorders obesity and related biomedical studies of lipid metabolic pathways
Apexbio Technology LLC Naftopidil 57149-07-2 10g
Naftopidil (CAS 57149-07-2) is a small molecule that functions as a selective antagonist of 1-adrenergic receptors By blocking these receptors naftopidil inhibits adrenergic signaling associated with smooth muscle contraction in the lower urinary tract and vascular tissues In clinical studies administration of naftopidil has been associated with significant improvements in international prostatic symptom scores demonstrating its impact on lower urinary tract symptoms Naftopidil is primarily investigated for its antihypertensive properties and its potential to ameliorate symptoms associated with benign prostatic hyperplasia making it relevant for research on urological and cardiovascular disorders
Apexbio Technology LLC Fuchsine base monohydrochloride 632-99-5 10g
Fuchsine base monohydrochloride (632-99-5) is a synthetic dye belonging to the triphenylmethane family It is designed for staining applications to visualize cellular and tissue components in histological and cytological studies Fuchsine base monohydrochloride exerts its biological activity primarily through binding with negatively charged groups particularly carboxyl-rich sites within cell structures Based on these properties Fuchsine base monohydrochloride holds research potential in biomedical cytological and histological applications for the analysis of tissue morphology cellular anatomy and biological process visualization

Apexbio Technology LLC L-Phenylephrine 59-42-7 10g
L-Phenylephrine (CAS 59-42-7) is a selective agonist of the adrenergic 1A receptor exhibiting a Ki of 1 4 M with markedly lower affinity for 1B (Ki 23 9 M) and 1C (Ki 47 8 M) subtypes In vitro L-Phenylephrine has been shown to reduce apoptosis in neonatal rat cardiomyocytes following hypoxia and serum deprivation and to stimulate proliferation in neural progenitor cells It also increases the cross-sectional area and modulates gene expression in rat neonatal cardiomyocytes In vivo local administration in rats induces cutaneous anesthesia through 1-adrenergic receptor activation and clinical data suggest oral administration reduces nasal airway resistance These properties make L-Phenylephrine a valuable tool for studying 1A-adrenergic receptor-mediated cellular responses
