Cayman Chemical, 5 mg, UN1544
-
Cytochalasin D
Cayman ChemicalA cell-permeable inhibitor that binds actin filaments, but not actin monomers, to inhibit polymerization at concentrations as low as 0.2 µM.
-
Cytochalasin B
Cayman ChemicalA cell-permeable mycotoxin which binds to the barbed end of actin, reversibly inhibiting the elongation and shortening of actin filaments; blocks diverse cellular functions, including cell division, migration, phagocytosis, exocytosis, chemotaxis, and glucose transport.
-
Cytochalasin A
Cayman ChemicalInhibits actin polymerization; uniquely inhibits HIV-1 protease (IC50 = 3 μM); rapidly and reversibly inhibits glucose transport by competitively binding glucose transporters (Ki = 4.0 μM); induces the phosphorylation of the tyrosine phosphatase PTP3 of Dictyostelium, activating STATc.
-
Muscimol
Cayman ChemicalA full GABAA agonist and partial GABAC agonist; binds GABAA on both high- and low-affinity sites (Kd = 10 and 270 nM, respectively), stimulating chloride efflux with an EC50 of 200 nM; activates GABAC receptors with an EC50 of 1.3 μM; impairs memory formation and retrieval; attenuates airway constriction.
-
Cytochalasin C
Cayman ChemicalA cell-permeable inhibitor of actin polymerization that has been shown to be 10 times less toxic in mice than cytochalasin D.
-
(-)-Huperzine A
Cayman ChemicalA natural sesquiterpene alkaloid that inhibits AChE in rat cortex in vitro (IC50 = 82 nM) and displays oral AChE inhibitory activity in animals.
