Sparfosic acid
Based on 6 publication(s) in Google Scholar
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.

Biological Activity
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 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.
-
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.
