体外研究
Piclamilast (RP 73401, 1 μM, 30 min) significantly inhibits the changes in 23 genes via mechanisms involving AP-1 activation and c-Jun phosphorylation at Ser63.
Piclamilast (RP 73401) exhibits IC 50 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.

体内研究
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.
