Bevacizumab is a recombinant humanized monoclonal antibody belonging to the immunoglobulin G1 (IgG1) subclass. It is designed to specifically bind to vascular endothelial growth factor A (VEGF-A), a critical signaling glycoprotein that regulates angiogenesis and vascular permeability. Structurally, Bevacizumab is composed of two identical heavy chains and two identical light chains, each linked by disulfide bonds to form a Y-shaped configuration typical of IgG antibodies, with a total molecular weight of approximately 149 kilodaltons (kDa).
The variable regions contain three complementarity-determining regions (CDRs) within each chain, forming the paratope that interacts with specific epitopes on human VEGF-A. This binding is mediated through hydrogen bonding, van der Waals forces, and electrostatic interactions that confer Bevacizumab high affinity and specificity, typically in the nanomolar range. The antigen-binding process is highly selective, preventing VEGF-A from engaging its native receptors, VEGFR-1 (Flt-1) and VEGFR-2 (KDR), located on the surface of endothelial cells. This molecular blockade inhibits receptor dimerization and downstream intracellular signaling cascades, including the MAPK and PI3K-AKT pathways, which are responsible for cellular proliferation, migration, and survival.
The constant (Fc) region of Bevacizumab contributes structural stability and extends the molecule’s circulating half-life through neonatal Fc receptor (FcRn) recycling. It also allows the antibody to maintain dimeric stability under physiological conditions. Bevacizumab’s glycosylation pattern within its Fc domain supports folding and solubility while minimizing undesired immune effector function such as complement activation or antibody-dependent cytotoxicity.
