Laulimalide is an Microtubule stabilizing agent. Laulimalide is a potent inhibitor of cellular proliferation in cancer cell lines (IC50 reported to be 3-30 nM, dependent on cell line used). Laulimalide causes cells to arrest in the prometaphase of the cell cycle, prevents formation of bipolar spindle and increases kinetochore tension in preformed spindles.
| Molecular Weight | 514.65 |
| Formula | C30H42O7 |
| CAS Number | 115268-43-4 |
| Solubility (25°C) | DMSO ~10 mg/mL |
| Storage | -20°C, sealed |
| Species | Mouse | Rat | Rabbit | Guinea pig | Hamster | Dog |
| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| 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.
