Forodesine (10-30 μM; 24 and 48 hours; RPMI-8226, MOLT-4 and 5T33MM cells) treatment is partially inhibition of proliferation[1].
Forodesine (10-30 μM; 24 and 48 hours; RPMI-8226, MOLT-4 and 5T33MM cells) has no effect on the MM cells at 24 hours, while it could reduce the percentage of living cells in the MOLT-4 cells with 40%[1].
Forodesine (BCX-1777), in the presence of 2'-deoxyguanosine (dGuo, 3-10 μM), inhibits human lymphocyte proliferation activated by various agents such as interleukin-2 (IL-2), mixed lymphocyte reaction (MLR) and phytohemagglutinin (PHA) (IC50 values < 0.1-0.38 μM)[2].

Correlation between PNP and HER-2 in SKBR3 cells. Western blot analysis showing protein expression levels of HER-2 and PNP in SKBR3 cells treated with vehicle control (CTL), Forodesine (BCX-1777, a PNP inhibitor; 10 μM; 48 h), or trastuzumab (a HER-2 inhibitor). The results showed that inhibition of PNP using BCX-1777 resulted in significant (p < 0.01) upregulation of HER-2 by ~1.45 fold.

SKBR3 cell viability was assessed using the MTT assay and expressed as a percentage relative to untreated control (CTL) cells. Data shown are representative blots from three independent biological replicates (n = 3). The results showed that treatment with Forodesine (BCX-1777, 10 μM; 48 h) alone, a pharmacological PNP inhibitor, significantly reduced the cell viability by ~30%. A combination of BCX-1777 with trastuzumab resulted in a further reduction in the cell viability (~34%, p < 0.01). These results demonstrated that inhibition of PNP enhanced the cytotoxic effect of HER-2 inhibition.

The adolescent mice were administered water either with or without 0-15 mg/kg Forodesine (BCX-1777) for 1 week, and then the ovaries were obtained for immunofluorescence and hematoxylin staining. The results showed that compared with the control, oral administration of 10 and 15 mg/kg BCX-1777 significantly decreased the number of growing follicles in the ovaries.
