Docetaxel-PNP

**Semantic type:** Organic Chemical|Pharmacologic Substance

**Definition:** A polymeric nanoparticle (PNP) formulation containing the taxane docetaxel, a semi-synthetic analogue of paclitaxel, with antineoplastic activity. Docetaxel binds specifically to the beta-tubulin subunit of the microtubule, stabilizing tubulin and inhibiting microtubule disassembly, which results in cell-cycle arrest at the G2/M phase, preventing cell proliferation. This agent also inhibits pro-angiogenic factors such as vascular endothelial growth factor (VEGF) and induces various mediators of the inflammatory response. Compared to docetaxel alone, the PNP formulation may enhance stability and improve delivery.

**Synonyms:** - PNP-DTX
