Pyramidatine
Pyramidatine (Haplamidine) is a P-glycoprotein inhibitor with an IC50 of 39.29 µM. As a sensitizer, Pyramidatine enhances Vincristine (HY-N0488A)-induced Apoptosis and G2/M phase arrest, while potentiating the activity of Vincristine against drug-resistant oral cancer. Pyramidatine can be used in research related to oral cancer and mammary adenocarcinoma.

Biological Activity
Pyramidatine (10 µM; 24 h) enhances VCR-induced apoptosis in KB/VCR cells, increasing the apoptotic rate to 31.31% when used at 10 µM in combination with 0.2 µM VCR for 24 h[1].
Pyramidatine (10 µM; 48 h) upregulates pro-apoptotic marker expression in KB/VCR cells when used at 10 µM in combination with 0.2 µM VCR for 48 h[1].
Pyramidatine (10 µM; 24 h) enhances VCR-induced G2/M arrest in KB/VCR cells, resulting in 97.44% of cells arrested in G2/M phase when used at 10 µM in combination with 0.2 µM VCR for 24 h[1].
Pyramidatine inhibits Verapamil (HY-14275)-stimulated P-gp ATPase activity in recombinant human P-gp membranes with an IC50 of 39.29 µM[1].
Pyramidatine (10 µM; 36 h) suppresses P-gp protein expression in KB/VCR cells[1].

-
Cell Line:KB/VCR cells
-
Concentration:10 µM (alone); 10 µM (combined with 0.2 µM VCR)
-
Incubation Time:24 h
-
Result:Induced 6.59% apoptosis in KB/VCR cells when used alone at 10 µM.
Increased the apoptotic rate to 31.31% when combined with 0.2 µM VCR, which was 2.13-fold higher than VCR alone (14.73%) and higher than the verapamil-positive control combination (21.83%).
-
Cell Line:KB/VCR cells
-
Concentration:10 µM (alone); 10 µM (combined with 0.2 µM VCR)
-
Incubation Time:48 h
-
Result:Significantly increased the expression of cleaved PARP and pro-apoptotic Bax protein in KB/VCR cells when combined with 0.2 µM VCR.
-
Cell Line:KB/VCR cells
-
Concentration:10 µM (alone); 10 µM (combined with 0.2 µM VCR)
-
Incubation Time:24 h
-
Result:Resulted in 22.41% of KB/VCR cells arrested in G2/M phase when used alone at 10 µM.
Increased the G2/M arrest rate to 97.44% when combined with 0.2 µM VCR, which was higher than VCR alone (63.18%) and the verapamil-positive control combination (89.57%).
