生物活性

製品説明 Pralatrexate is an antifolate, and structurally a folate analog. Its IC50 is < 300 nM in some cell lines. Pralatrexate induces tumor cell apoptosis.
in vitro Pralatrexate and bortezomib exhibits concentration- and time-dependent cytotoxicity against a broad panel of T-lymphoma cell lines. This compound shows synergism when combined with bortezomib in all cell lines studied. It also induces potent apoptosis and caspase activation when combined with bortezomib across the panel. The agent significantly modulates the expression of p27, NOXA, HH3, and RFC-1 as assessed by Western blot assays. [1] This compound is rationally designed for improved cellular transport via RFC-1, and to have greater intracellular drug retention through the enhanced formation of polyglutamylated conjugates. It is thought to exert its pharmacological effect primarily through inhibition of DHFR, having an IC50 in the picomolar range. [2] This chemical demonstrates superior intracellular transport via the reduced folate carrier, and increased accumulation within cells by enhanced polyglutamylation. It exhibits antitumor activity that is superior to the activity of other antifolates. [3] Its enhanced activity relative to methotrexate (MTX) is due to its much more rapid rate of transport and polyglutamation, the former less important when the carrier is saturated. [4]
in vivo Pralatrexate treatment results in treatment-related toxicity in MV522 mice models, as determined by significant weight loss in some animals prior to death; however, remaining mice regains all lost weight by Day 35. [2]
