Forodesine(BCX-1777 freebase; Immucillin-H) is an orally bioavailable PNP inhibitor with picomolar potency; induces apoptosis, mainly in T cells.IC50 value:Target: PNP inhibitorForodesine and ara-G cytotoxicities were higher in T-cell acute lymphoblastic leukemia (T-ALL) samples than in B-cell precursor (BCP)-ALL and acute myeloid leukemia (AML) samples. Resistance to forodesine did not preclude ara-G sensitivity and vice versa, indicating that both drugs rely on different resistance mechanisms [1]. BCX1777 was well tolerated at doses up to 300 mg once daily and showed preliminary evidence of activity in relapsed or refractory peripheral T/natural killer-cell malignancies, warranting further investigation [2]. after 48 hours of treatment with forodesine there was a slight dGTP increase in 5T33MM and RPMI-8226 MM cells associated with partial inhibition of proliferation and a limited induction of apoptosis [3]. In the presence of 10 μM deoxyguanosine, forodesine effectively inhibited the growth of CEM cells but not that of CEM/ara-G cells [4].
