Sparfosic acid trisodium

产品介绍

Sparfosic acid trisodium 是天门冬氨酸氨甲酰转移酶 (aspartate transcarbamoyl transferase) 的有效抑制剂，具有抗肿瘤和抗代谢物活性。天冬氨酸氨甲酰转移酶催化第二步 de novo 嘧啶生物合成。Sparfosic acid trisodium 协同增强 5-氟尿嘧啶 (5-FU) 和干扰素-α (IFN) 对人结肠癌细胞系的细胞毒性。

生物活性

Sparfosic acid trisodium is a DNA antimetabolite agent and a potent inhibitor of aspartate transcarbamoyl transferase. Aspartate transcarbamoyl transferase catalyzes the second step of de novo pyrimidine biosynthesis. Sparfosic acid trisodium synergistically enhances the cytotoxicity of a combination of 5-fluorouracil (5-FU) and interferon-alpha (IFN) against human colon cancer cell lines.

体外研究

Sparfosic acid (N-(Phosphonacetyl)-L-aspartate, PALA) treatment causes apoptosis in the resistant Br1 cells.
Sparfosic acid (PALA, 300 µM) shows progressive accumulation of cells in S phase and activation of an apoptotic pathway leading to cell death.

Cell Cycle Analysis

Cell Line:	Br-l and L-2 cell lines established from metastasis in nude mouse injected with the human tumor cell line MDA-MB-435.
Concentration:	300 µM.
Incubation Time:	12, 24 and 48 h.
Result:	Cells were predominantly in S phase in both the cell lines, although slightly higher proportion of cells in S phase were noted in L-2 than Brl-3prl cells.

Western Blot Analysis

Cell Line:	Br-l and L-2 cell lines.
Concentration:	300 µM.
Incubation Time:	4, 10 and 24 h.
Result:	There was moderate difference in the level of phosphorylated Rb proteins seen in the two cell types. Marked increase in the amount of cyclin A protein was detected in the L-2 cells undergoing apoptosis with the highest level detected at 10 h post-drug treatment. In contrast, there was no increase in the level of cyclin A seen in the Brl-3prl cells. Cyclin E protein was found elevated in the L-2 cells and Brl-3prl cells compared to their respective controls.

体内研究
(In Vivo)

Sparfosic acid (490 mg/kg; i.p.; on days 1, 5, and 9; mice bearing B16 melanoma) trisodium shows the life-span is increased survives 77 to 86% longer than controls. Lewis lung carcinoma is highly sensitive to Sparfosic acid trisodium. Treatment on days 1, 5, and 9 following s.c. implantation of Lewis lung carcinoma is curative to 50% of the mice^[4].
