Protein-bound paclitaxel, also known as nanoparticle albumin–bound paclitaxel or nab-paclitaxel, is an injectable formulation of paclitaxel used to treat breast cancer, lung cancer and pancreatic cancer, among others. Paclitaxel kills cancer cells by preventing the normal breakdown of microtubules during cell division.
Paclitaxel is one of several cytoskeletal drugs that target tubulin. Paclitaxel-treated cells have defects in mitotic spindle assembly, chromosome segregation, and cell division. Unlike other tubulin-targeting drugs, such as colchicine, that inhibit microtubule assembly, paclitaxel stabilizes the microtubule polymer and protects it from ...

A drug in blood exists in two forms: bound and unbound. Depending on a specific drug's affinity for plasma proteins, a proportion of the drug may become bound to the proteins, with the remainder being unbound. If the protein binding is reversible, then a chemical equilibrium will exist between the bound and unbound states, such that:
In 2013, the U.S. Food and Drug Administration approved protein-bound paclitaxel (also known as nab-paclitaxel, sold as Abraxane) used with gemcitabine. This regimen may be less toxic—but perhaps less effective—alternative to FOLFIRINOX for treating late-stage pancreatic cancer.
The structure of paclitaxel, a widely used mitotic inhibitor.. A mitotic inhibitor, microtubule inhibitor, or tubulin inhibitor, is a drug that inhibits mitosis, or cell division, and is used in treating cancer, gout, and nail fungus.
These drugs act nonspecifically. Electrophilic alkylating agents such as nitrogen mustards, methanesulfonates, and cisplatins tend to act in this manner to produce a variety of DNA damage products such as mono- and dialkylation, inter- and intrastrand crosslinks, and DNA-protein crosslinks.
