Epoxomicin
Antibiotic. Potent anticancer compound. Cell permeable, potent, selective and irreversible 20S proteasome inhibitor. Predominantly inhibits the chymotrypsin-like (CTRL) activity of the proteasome. Exhibits lower level inhibition of proteasome trypsin-like and caspase-like activitives (100 and 1,000-fold slower rates respectively). Anti-inflammatory. Antimicrobial and antimalarial. Anti-parasitic. Stimulates bone formation by inhibiting osteoblast proteasome activity. Induces Parkinson's-like symptoms in rats. The ubiquitin-proteasome system (UPS) and autophagy serve as two complementary, reciprocally regulated protein degradation systems. Blockade of UPS by Epoxomicin activates autophagy.

Lanreotide
Laromustine is a sulfonyl hydrazine prodrug with antineoplastic activity. Laromustine releases the DNA chloroethylating agent 90CE after entering the blood stream; 90CE chloroethylates alkylates the 06 position of guanine, resulting in DNA crosslinking, strand breaks, chromosomal aberrations, and disruption of DNA synthesis. Intracellular metabolism of this agent also releases methyl isocyanate which inhibits 06-alkyl-guanine transferase, an enzyme involved with DNA repair.
