Necuparanib

**Semantic type:** Pharmacologic Substance

**Definition:** A low molecular weight heparin derivative and heparan sulfate proteoglycan (HSPG) mimetic with no or minimal anticoagulant activity and potential antineoplastic activities. Upon administration, necuparanib mimics HSPGs by binding to and inhibiting various heparin-binding growth factors, chemokines, and cytokines such as VEGF, HGF, FGF2, SDF-1a, heparanase and P-selectin all of which are essential for tumor angiogenesis and metastasis to occur. This inhibits heparin binding growth factor-mediated signaling and disrupts tumor-stromal interactions eventually leading to an inhibition of angiogenesis and tumor cell progression. In addition, M402 may enhance the cytotoxic effect of other chemotherapeutic agents.

**Synonyms:** - HSGAG Mimetic M402 - Heparan Sulfate Glycosaminoglycan Mimetic M402 - M402 - NECUPARANIB
