DPAP
DPAP is a p-ERK1/2 inhibitor with an IC50 of 7.85 μM against p-ERK1/2. DPAP inhibits the expression of p-MEK1/2 and disrupts the Ras-ERK signaling pathway. DPAP inhibits the expression of COX-2 in nerve cells. DPAP damages DNA and mitochondria, induces Apoptosis via the mitochondrial pathway, and upregulates PD-L1. DPAP inhibits melanoma metastasis and angiogenesis, and inactivates spinal microglia and astrocytes. DPAP exhibits anti-melanoma activity and can be combined with anti-PD-1 monoclonal antibodies to modify anti-tumor effects. DPAP is applicable for the research of melanoma.

The cellular uptake of DPAP (2 μM; 72 h) in A375 melanoma cells is 2.53-fold higher than that of CDDP[1].
DPAP (72 h) inhibits the proliferation of melanoma A375 cells, mouse melanoma B16-F10 cells, and normal renal HK-2 cells. After 72 h of incubation, its IC50 values are 8.05 μM, 5.96 μM, and 35.12 μM, respectively, indicating selective cytotoxicity against cancer cells[1].
DPAP (1-8 μM; 72 h) increases the level of DNA-bound Pt in A375 melanoma cells; at 8 μM for 72 h, it upregulates the expression of γ-H2AX, indicating the presence of DNA damage[1].
DPAP (8 μM; 48 h) induces S-phase cell cycle arrest in melanoma A375 cells[1].
DPAP (8 μM; 72 h) regulates the expression of apoptosis-related proteins (upregulating Cyt c and Bax, downregulating Bcl-2) and induces late apoptosis in human melanoma A375 cells[1].
DPAP (8 μM; 72 h) regulates the Ras-ERK signaling pathway in melanoma A375 cells[1].
DPAP (8 μM; 24 h) downregulates the expressions of p-ERK1/2 and COX-2, but does not alter the expression of NF-L, in HT22 mouse hippocampal neuronal cells[1].

Cell Line:A375 cells
-
Concentration:8 μM
-
Incubation Time:48 h
-
Result:Arrested A375 cells primarily in the S phase, similar to CDDP, indicating inhibition of DNA synthesis.
-
Cell Line:A375 cells
-
Concentration:8 μM
-
Incubation Time:72 h
-
Result:Significantly downregulated p-MEK1/2 and p-ERK1/2 expression relative to control cells, while having only slight effects on NRAS, MEK1/2, and ERK1/2 expression.
-
Cell Line:HT22 cells
-
Concentration:8 μM
-
Incubation Time:24 h
-
Result:Suppressed p-ERK1/2 and COX-2 expression in HT22 cells relative to control cells, and did not affect NF-L expression, unlike CDDP which reduced NF-L levels.
DPAP (1.5 mg Pt kg−1; intravenous injection; once every 2 days; for 1 week) inhibits the activation of microglia and astrocytes in the spinal dorsal horn of melanoma-bearing mice, demonstrating potential to alleviate cancer pain-related central sensitization[1].
Combination treatment with DPAP (2.5 mg Pt kg-1; intravenous injection; once every 2 days; for 2 consecutive weeks) and anti-PD-1 mAb (12.5 mg kg-1; intravenous injection; administered on days 4, 9 and 14) synergistically enhances the anti-melanoma efficacy[1].
DPAP (10-40 mg kg-1; intravenous injection; once every 2 days) exhibits a high median lethal dose of 33.60 mg kg-1 and favorable biocompatibility in healthy female C57BL/6 mice[1].
