It is structurally analogous to belamide A and dolastatin 15. It's appearance is that of a powdery, white, substance.

Structural Characteristics and Determination
The N-terminus for Caldoramide is N,Ndimethylvaline which is attached to a valine which is attached to an N-Me-valine connected to an N-Me-isoleucine which is attached to the C-terminus. The molecule can also be written as N,N-diMe-Val-Val-N-Me-ValN-Me-Ile-3-O-Me-4-benzylpyrrolinone.

Extraction
Freeze-dried samples of Caldora penicillata had EtOAc−MeOH and H2O−EtOH applied to them in order to extract Caldoramide. The extractswere partitioned with n-BuOH and H2O and then fractions were taken based on solubility in either EtOAc or BuOH. Caldoramide was extracted from the BuOH soluble fraction.

Pharmacological Relevance
Caldoramide has been found to be effective at combatting cancerous pathways.
