Mechanism of Action
Bortezomib selectively and reversibly inhibits the 26S proteasome, targeting the ?5 catalytic subunit (PSMB5). This causes accumulation of misfolded and regulatory proteins (e.g., p21, p27, p53, I?B?), leading to cell-cycle arrest, apoptosis, reduced angiogenesis, and suppressed tumor growth.

Research Applications & Pharmacology
-
Oncology models: Demonstrates antitumor efficacy in preclinical studies of multiple myeloma, mantle-cell lymphoma, lung, breast, prostate, pancreatic, colon cancers, melanoma, and head & neck cancers, resulting in reduced tumor growth, angiogenesis, metastasis, and extended survival.
-
Mechanism-focused studies: Shows effects on NF??B inhibition, JNK activation, ER stress pathways, and apoptotic signaling.
-
Combination research: Enhances efficacy when used with chemotherapy, radiation, immunotherapy, and novel agents without increasing toxicity in animal models.
-
Pharmacokinetics: Administered IV or SC. Half-life ~9–15 hours; proteasome inhibition sustains ~72 hours post-dose.
Safety Profile & Key Precautions
Preclinical and clinical observations include:
-
Myelosuppression: Neutropenia, thrombocytopenia
-
Gastrointestinal: Nausea, diarrhea
-
Neuropathy: Sensory peripheral neuropathy
-
Other effects: Fatigue, fever, rash, hypotension, tumor lysis syndrome
-
Lethality in high-dose animal studies (?1.5?mg/kg) with weight loss and GI inflammation
Lab Handling Suggestions:
-
Reconstitute under sterile conditions
-
Dose carefully in vivo, monitor blood count and weight
-
Ensure PPE and safe disposal protocols are followed
