Apexbio Technology LLC Sulfadoxine 2447-57-6 10g
Sulfadoxine (CAS 2447-57-6) is a small-molecule inhibitor targeting dihydropteroate synthase It is designed to competitively inhibit this enzyme thereby disrupting folate biosynthesis in Plasmodium parasites Sulfadoxine exerts its biological activity primarily through inhibition of dihydropteroate synthase mediated folate synthesis In cell-based studies sulfadoxine demonstrates inhibitory activity against human immunodeficiency virus (HIV) replication within peripheral blood mononuclear cells (PBMCs) with an IC50 value in the micromolar range Based on these pharmacological properties sulfadoxine holds research potential in antimalarial drug investigation parasite metabolic pathway studies pathogen susceptibility assays antiviral pharmacological experiments and investigations of host-pathogen interactions and viral replication mechanisms
Apexbio Technology LLC Spermine 71-44-3 10g
Spermine (71-44-3) is a small-molecule inhibitor targeting inward rectifier potassium (K ) channels It is designed to block channel conductance thereby modulating cellular excitability and resting membrane potential Spermine exerts its biological activity primarily through direct inhibition of K channel function In experimental studies spermine demonstrates strong channel inhibition with an IC50 value of approximately 31 nM at a membrane potential of 50 mV in cloned IRK1 potassium channels Based on these pharmacological properties spermine holds research potential in potassium channel modulation neuronal excitability studies and investigation of neurological conditions associated with altered glutamatergic signaling and polyamine metabolism
Apexbio Technology LLC Clofibrate 637-07-0 10g
Clofibrate (CAS 637-07-0) is a small-molecule agonist targeting peroxisome proliferator-activated receptor alpha (PPAR-alpha) It is designed to activate PPAR-alpha thereby regulating lipid and lipoprotein metabolism pathways Clofibrate exerts its biological activity primarily through PPAR-alpha activation leading to enhanced peroxisome proliferation and fatty acid oxidation In both human and mouse models Clofibrate demonstrates agonist activity with EC50 values of 55 M and 500 M respectively Based on these pharmacological properties Clofibrate holds research potential in investigating lipid metabolism triglyceride regulation and the roles of PPAR-alpha signaling in hyperlipidemia and related metabolic disorders
