Manumycin A is a selective, competitive inhibitor of protein farnesyl transferase (FTase) with respect to farnesylpyrophosphate (Ki=1.2 μM), and as a noncompetitive inhibitor with respect to the Ras protein.
Manumycin A is also an antibiotic. Manumycin A induces apoptosis and exerts antitumor activity.
Manumycin A suppresses exosome biogenesis and secretion via targeted inhibition of Ras/Raf/ERK1/2 signaling.
Manumycin A is a nSMase inhibitor with EC50 of 0.25 μM.

| 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.
