Lometrexol hydrate  (Synonyms: DDATHF hydrate)

目錄號: HY-14521B 純度: ≥99.0%
COA 產(chǎn)品使用指南

Lometrexol (DDATHF) hydrate 是一種抗嘌呤類抗葉酸 (antifolate) 藥,可抑制甘氨酰胺核糖核苷酸甲?;D(zhuǎn)移酶 (GARFT) 的活性,但不會引起可檢測水平的 DNA 鏈斷裂。Lometrexol hydrate 可以進一步抑制嘌呤從頭合成,導致異常的細胞增殖,凋亡 (apoptosis) 和細胞周期停滯。Lometrexol hydrate 具有抗癌活性。Lometrexol hydrate 還是一種有效的人絲氨酸羥甲基轉(zhuǎn)移酶 1/2 (hSHMT1/2) 抑制劑。

生物活性

Lometrexol (DDATHF) hydrate, an antipurine antifolate, can inhibit the activity of glycinamide ribonucleotide formyltransferase (GARFT) but do not induce detectable levels of DNA strand breaks. Lometrexol hydrate can further inhibit de novo purine synthesis, causing abnormal cell proliferation and apoptosis, even cell cycle arrest. Lometrexol hydrate has anticancer activity. Lometrexol hydrate also is a potent human Serine hydroxymethyltransferase1/2 (hSHMT1/2) inhibitor[1][2][3].

體外研究
(In Vitro)

Lometrexol (DDATHF) 水合物與 GART 緊密結(jié)合,導致細胞內(nèi)嘌呤核糖核苷酸快速和長時間消耗[3]
Lometrexol (1-30 μM;2-10 小時) 水合物誘導 L1210 細胞的快速和完全生長抑制[3]。
Lometrexol (1 μM;2-24 小時) 水合物誘導小鼠白血病 L1210 細胞的細胞周期停滯[3]。

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

Cell Viability Assay[3]

Cell Line: Mouse leukemia L1210 cells
Concentration: 1, 30 μM
Incubation Time: 2, 4, 6, 8, 10 hours
Result: Induced rapid and complete growth inhibition.

Cell Cycle Analysis[3]

Cell Line: L1210 cells
Concentration: 1 μM
Incubation Time: 2, 4, 8, 12, 24 hours
Result: Caused a rapid loss of the G2/M phase population of cells and an early S phase accumulation of cells by 8 hours. By 24 h, the S phase population appeared to be slowly shifting to higher DNA content, and hence, from mid-to-late S phase.

Animal Model: C57BL/6 mice (7-8 week, 18-20 g)[1]
Dosage: 15, 30, 35, 40, 45 and 60 mg/kg
Administration: Intraperitoneal injection; on gestation day 7.5
Result: Increased the rate of embryonic resorption and growth retardation in a dose-dependent manner.
Animal Model: C57BL/6 mice (7-8 week, 18-20 g)[1]
Dosage: 40 mg/kg
Administration: Intraperitoneal injection; on gestation day 7.5
Result: Inhibited glycinamide ribonucleotide formyl transferase (GARFT) activity and GARFT activity was maximally inhibited after at 6 hours.
Decreased the levels of ATP, GTP, dATP, and dGTP of NTDs embryonic brain tissue significantly at 6 hours.
Animal Model: C57BL/6 mice (7-8 week, 18-20 g)[1]
Dosage: 40 mg/kg
Administration: Intraperitoneal injection; on gestation day 7.5, for 4 days
Result: Decreased the expression of proliferation-related genes (Pcna, Foxg1 and Ptch1) and increased the expression of apoptosis-related genes (Bax, Casp8 and Casp9) in NTD groups.

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.
