| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

EG-011 is a first-in-class, potent Wiskott-Aldrich Syndrome Protein (WASP) activator that activates the self-inhibited form of WASP via strong actin polymerization.In addition, EG-011 has selective anti-lymphoma activity. |
| Dihydrocytochalasin B
Dihydrocytochalasin B is a Cytokinesis inhibitor and changes the morphology of the cells, similar to that of cytochalasin B. |
| Cytochalasin B
Cytochalasin B is a cell-permeable mycotoxin binding to the barbed end of actin filaments, disrupting the formation of actin polymers, with Kd value of 1.4-2.2 nM for F-actin. |
| Jasplakinolide
Jasplakinolide is an actin-specific reagent that promotes actin polymerization and stabilizes actin filaments. |
| Cytochalasin D
Cytochalasin D is a cytopermeable actin polymerization inhibitor derived from fungi, which inhibits g-actin -- Cofilin interaction by binding g-actin. Cytochalasin D can also inhibit the binding of Cofilin to F-actin, reduce the release of exosomes and induce YAP phosphorylation. |
