Apexbio Technology LLC Tolbutamide 64-77-7 1g
Tolbutamide (CAS 64-77-7) is a small molecule inhibitor known to suppress cyclic adenosine monophosphate (cAMP)-dependent protein kinase activity with an IC50 value of 4 mM It reduces both basal and cAMP-stimulated kinase activities in cellular models including soluble and membrane-bound forms from canine cardiac tissue In adipose tissue tolbutamide s inhibition of cAMP-dependent protein kinase underlies its reported suppression of lipolysis Additionally tolbutamide has been shown to increase connexin43 mRNA levels while decreasing Ki-67 expression in glioma cells suggesting roles in cell proliferation studies This compound is used in research focused on kinase signaling and metabolic regulation
Apexbio Technology LLC Bifonazole 60628-96-8 1g
Bifonazole (60628-96-8) is a small-molecule inhibitor targeting sterol 14 -demethylase It is designed to block this enzyme thereby impairing ergosterol biosynthesis critical to fungal membrane structure and function Bifonazole exerts its biological activity primarily through inhibition of sterol 14 -demethylase In in vitro studies Bifonazole demonstrates antifungal inhibitory activity with reported IC50 values generally ranging from 0 5 to 4 g/mL depending on fungal species and experimental conditions Based on these pharmacological properties Bifonazole holds research potential in antifungal efficacy evaluation and mechanism-specific assays targeting sterol biosynthesis and membrane disruption
Apexbio Technology LLC LAP 85073-19-4 1g
Lithium phenyl-2 4 6-trimethylbenzoylphosphinate (LAP CAS 85073-19-4) is a photoinitiator that generates free radicals upon exposure to light Through this radical formation LAP facilitates photopolymerization reactions commonly employed in biomedical research such as the fabrication of hydrogels for 3D bioprinting applications The free radicals produced by LAP can exert cytotoxic and potentially mutagenic effects under experimental conditions necessitating careful optimization in cell-based assays LAP is widely utilized for controlled light-mediated crosslinking in tissue engineering and biofabrication studies
Apexbio Technology LLC Sulforhodamine B sodium salt 3520-42-1 1g
Sulforhodamine B sodium salt (CAS 3520-42-1) is a fluorescent dye used for quantification of total cellular protein Sulforhodamine B sodium salt functions by electrostatically binding to cellular protein residues In cell-based studies fluorescence intensity after washing off unbound dye reflects the protein content of cultured cells This principle is applied for protein quantification assays including cytotoxicity assessments and cell proliferation assays Based on these properties Sulforhodamine B sodium salt is utilized in cell biology and biomedical research applications
Apexbio Technology LLC L-(-)-α-Methyldopa (hydrate) 41372-08-1 1g
L-(-)- -Methyldopa (hydrate) (CAS 41372-08-1) is a small molecule that functions as an agonist selective for 2-adrenergic receptors Through its sympatholytic properties it diminishes central adrenergic outflow resulting in decreased blood pressure This compound is widely utilized in biomedical research to investigate mechanisms of adrenergic signaling and to model antihypertensive pharmacological effects Its ability to modulate neurotransmitter pathways makes it a useful tool for studies of cardiovascular regulation and central nervous system pharmacodynamics
Apexbio Technology LLC Calcium Levofolinate 80433-71-2 1g
Calcium Levofolinate (CAS 80433-71-2) is the calcium salt of levoleucovorin the biologically active enantiomer of folinic acid It functions as a reduced folate cofactor bypassing dihydrofolate reductase inhibition to support DNA and RNA synthesis In biomedical research Calcium Levofolinate is used to modulate the effects of antifolate chemotherapeutic agents such as methotrexate reducing cytotoxicity in normal cells It is also investigated for its ability to enhance the cytotoxic activity of 5-fluorouracil through stabilization of the ternary complex with thymidylate synthase facilitating studies on nucleotide metabolism and chemotherapeutic mechanisms
