Summary
This review details the development of Herceptin, a targeted therapy for HER2-positive breast cancer. It highlights key decisions in creating the first successful tyrosine kinase inhibitor for cancer treatment.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- The human epidermal growth factor receptor-2 (HER2) is a validated target for cancer therapy.
- Herceptin is a monoclonal antibody approved for HER2-positive breast cancer treatment, used in over 150,000 women.
- Understanding the developmental history of Herceptin offers insights into targeted drug discovery.
Observation:
- The specific developmental history, critical decision points, and rationale for pursuing a monoclonal antibody approach for HER2 have not been fully documented.
- This review aims to elucidate these pivotal events and decisions.
- The development of Herceptin represents a significant milestone in targeted cancer therapeutics.
Findings:
- The review details the critical events and decision-making processes that led to the development of Herceptin.
- It explains the strategic choices made during the drug discovery and development program.
- Herceptin emerged as the first therapeutic agent successfully targeting tyrosine kinases in cancer.
Implications:
- Sharing the Herceptin development experience can inform future drug discovery and development processes.
- The success of Herceptin provides a model for developing targeted therapies against other HER family members.
- New therapeutic strategies and future directions for targeting the HER family are discussed.

Anticoagulant Drugs: Low-Molecular-Weight Heparins
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
Antiviral Nucleoside Inhibitors
Antiviral Nucleoside InhibitorsAntiviral nucleoside inhibitors are structural analogs of natural nucleosides that interfere with viral DNA or RNA synthesis. These compounds selectively target viral polymerases due to their resemblance to host nucleosides, thereby disrupting viral genome replication.Mechanism of Acyclovir ActionAcyclovir is a guanosine analog with a three-carbon acyclic side chain. It selectively targets herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2),...
Export of Misfolded Proteins out of the ER
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...
Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
