values >100 μM, 40 μM, >100 μM, 14 μM for PDE1, PDE2, PDE3 and PDE5. Respectively.
RT-PCR
| Cell Line: | Human A549 type II lung epithelial cells. |
| Concentration: | 1 μM (H 2 O 2 200 μM). |
| Incubation Time: | 30 min. |
| Result: | Prevented H 2 O 2 -induced changes in gene expression levels in A549 cells. |
Cell Viability Assay
| Cell Line: | NB4 cells. |
| Concentration: | 30 μM. |
| Incubation Time: | 3 days. |
| Result: |
Exerted a significant enhancing effect on the induction of STAT1 observed in ATRA-treated NB4 cells.
Caused a significant increase in the number of cells expressing NBT-R activity. |
Piclamilast (RP 73401, 10 mg/kg, 30 min) alone does not affect the MST of leukemia-bearing animals. Piclamilast combined with ATRA (HY-14649) significantly more effective than ATRA alone in increasing the MST (40 days; interval 34–45 days) of leukemia-bearing animals.
| Animal Model: | SCID mice. |
| Dosage: | 10 mg/kg (combined with ATRA (HY-14649)). |
| Administration: | Injection daily. |
| Result: | Significantly more effective than ATRA alone in increasing the MST (40 days; interval 34–45 days) of leukemia-bearing animals. |
