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

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Sparfosic acid trisodium) usually boasts enhanced water solubility and stability.

Description

Sparfosic acid, a DNA antimetabolite agent, is a potent inhibitor of aspartate transcarbamoyl transferase, the enzyme catalyzing the second step of de novo pyrimidine biosynthesis. Sparfosic acid synergistically enhances the cytotoxicity of a combination of 5-fluorouracil (5-FU) and interferon-alpha (IFN) against human colon cancer cell lines[1][2][3].

In Vitro

Sparfosic acid (N-(Phosphonacetyl)-L-aspartate, PALA) causes apoptosis in the resistant Br1 cells[1].
Sparfosic acid (300 µM) shows progressive accumulation of cells in S phase and activation of an apoptotic pathway leading to cell death[1].

Cell Viability Assay[1]

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 hours
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[1]

Cell Line: Br-l and L-2 cell lines
Concentration: 300 µM
Incubation Time: 4, 10 and 24 hours
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.
In Vivo

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

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.
