Dalotuzumab (MK-0646) is a recombinant humanized IgG1 monoclonal antibody that specifically targets the insulin-like growth factor 1 receptor (IGF-1R). its mechanism of action involves the inhibition of IGF-mediated oncogenic signaling, which subsequently induces apoptosis and cell cycle arrest in tumor cells, and it has demonstrated enhanced antitumor efficacy when used in combination with other chemotherapeutic agents.

Description | Dalotuzumab (MK-0646) is a recombinant humanized IgG1 monoclonal antibody that specifically targets the insulin-like growth factor 1 receptor (IGF-1R). its mechanism of action involves the inhibition of IGF-mediated oncogenic signaling, which subsequently induces apoptosis and cell cycle arrest in tumor cells, and it has demonstrated enhanced antitumor efficacy when used in combination with other chemotherapeutic agents. |
In vitro | Dalotuzumab (33 nM, 24 h) was used to treat IGF-1-induced MCF7 cells, and the changes in cell cycle and the expression of IGF-IR and IRS-1 proteins were detected. Results: Dalotuzumab was able to induce cell cycle arrest in IGF-1-induced MCF7 cells and also inhibited the autophosphorylation of IGF-IR and IRS-1. [1] |
In vivo | Methods: Dalotuzumab (MK-0646) (250 µg/mouse initially, then 125 µg/mouse, intraperitoneally twice a week for 40 days) was used to treat Swiss nude mice bearing MCF-7 and A549 xenograft tumors, and its tumor inhibition was observed. Results: Dalotuzumab reduced the average tumor volume of nude mice in the MCF-7 and A549 models by 70% and 72%, respectively. [1] |
