Description
Curator's Comment: Description was created using several sources including: https://www.ncbi.nlm.nih.gov/pubmed/16778146 | http://investor.shareholder.com/biocryst/releasedetail.cfm?releaseid=179991 | https://www.ncbi.nlm.nih.gov/pubmed/17016779 | https://clinicaltrials.gov/ct2/show/NCT00289562 | http://www.ema.europa.eu/docs/en_GB/document_library/Orphan_designation/2009/10/WC500006254.pdf

Forodesine hydrochloride is the salt of the synthetic high-affinity transition-state analog forodesine (BCX-1777, immucillin-H), a substrate designed to mimic the properties or the geometry of the transition state of reaction. It is an anticancer drug that has been developed for the treatment of different hematologic malignancies. In December 2006, orphan designation (EU/3/06/421) was granted by the European Commission to Napp Pharmaceuticals Research Limited, United Kingdom, for forodesine hydrochloride for the treatment of acute lymphoblastic leukemia. Forodesine hydrochloride has been evaluated in Phase I/Phase II clinical trials for several cancer types including chronic lymphocytic leukemia (CLL), B-Cell acute lymphoblastic leukemia and refractory cutaneous T-cell lymphoma (CTCL). Forodesine is a potent purine nucleoside phosphorylase (PNP) inhibitor that acts by elevating plasma 2'-deoxyguanosine (dGuo) and intracellular deoxyguanosine triphosphate, which in turn affects deoxynucleotide-triphosphate pools and induces cell death by apoptosis. Forodesine in the presence of dGuo inhibited the proliferation of CEM-SS (T-acute lymphoblastic leukemia) cells with an IC50 of 0.015 uM. This inhibition by forodesine and dGuo was accompanied by a 154-fold and 8-fold elevation of endogenous dGuo triphosphate (dGTP) and deoxyadenosine triphosphate (dATP) pools, respectively. Cytotoxic activity of forodesine in the presence of dGuo was selective to T lymphocytes. It is a 10- to 100-fold more potent inhibitor of human lymphocyte proliferation than other known PNP inhibitors such as PD141955 and BCX-34.8

Sample Use Guides

In Vivo Use Guide
Forodesine (200 mg/day) for up to 24 weeks in patients with advanced, fludarabine-treated chronic lymphocytic leukemia
Route of Administration: Oral
In Vitro Use Guide
Primary human CLL lymphocytes were incubated on the same day of their isolation from blood with or without 2 uM forodesine and 10 uM dGuo for 0, 4, 8, 16, and 24 hours. The nucleotides in the leukemia cells were extracted by 60% methanol and the dNTPs were quantitated by DNA polymerase assay in these cell extracts. CLL cells showed a wide variation in the accumulation of intracellular dGTP without any effect on other deoxynucleotides.
