Molarity Calculator

Trimetrexate (CI-898) isethionate is an antibiotic, also a potent and orally active dihydrofolate reductase (DHFR) inhibitor, reducing the production of DNA and RNA precursors and leading to cell death, with IC50 values of 4.74 nM and 1.35 nM for human DHFR and Toxoplasma gondii DHFR. Trimetrexate isethionate can also inhibit the growth of various cancer cells. Trimetrexate isethionate can be used for researching Pneumocystis carinii pneumonia (PCP) and cancer.

IC50 & Target[1]

Toxoplasma

 

In Vitro

Trimetrexate isethionate (0.1 μM; 18 h) completely inhibits proliferation of toxoplasma in murine macrophages[3].
Trimetrexate isethionate (1 μM) can cross the toxoplasma cell membrane and rapidly reaches high intracellular concentrations (108 pmol/107 cells within 10 min) [3].
Trimetrexate (0.1 mM; 24 h) inhibits cell growth by 50-60% in SNU-C4 and NCI-H630 cell lines[5].
Trimetrexate (1 and 10 mM; 24 h) produces lethality and inhibits DHFR in C4 cells[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay[5]

Cell Line: SNU-C4 and NCI-H630
Concentration: 0.1 mM
Incubation Time: 24 h
Result: Inhibited cell growth by 50-60% in both cell lines.

Cell Proliferation Assay[5]

Cell Line: C4 cells
Concentration: 1 and 10 mM
Incubation Time: 24 h
Result: Produced 42% and 50% lethality at 1 and 10 mM, respectively.
In Vivo

Trimetrexate (180 mg/kg or 30 mg/kg; p.o. or i.p.; daily) isethionate extends the median survival of the toxoplasma infected mice and shows antitoxoplasma activity[3].
Trimetrexate (0-30 mg/kg; i.v.; once daily for 5days) isethionate shows chronic toxicity in rats[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Toxoplasma infected female BALB/c mice weighing about 20 g[3]
Dosage: 180 mg/kg or 30 mg/kg
Administration: 180 mg/kg per day orally in the drinking water or 30 mg/kg per day i.p.
Result: Extended the median survival of the infected mice to 10 d (p.o.) or 19 d (i.p.).
Animal Model: Charles River Wistar Crl(WI)BR rats weighing approximately 150 to 200 g[4]
Dosage: 0, 1, 10, or 30 mg/kg
Administration: Intravenous injection, once daily for 5 consecutive days followed by a 23-day recovery period
Result: Showed chronic toxicity, the testicular changes persisting during the course of multiple cycles of dosing were not reversible within 21 days, but required an additional 56 days for essentially complete recovery.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
