Peldesine (BCX 34) dihydrochloride 是一种有效的，竞争性，可逆和口服活性的嘌呤核苷磷酸化酶 (PNP) 抑制剂，对人，大鼠和小鼠红细胞 (RBC)PNP的IC50分别为 36 nM，5 nM 和 32 nM。Peldesine dihydrochloride 还是一种 T 细胞 (T-cell) 增殖抑制剂，IC50为 800 nM。Peldesine dihydrochloride 可用于皮肤 T 细胞淋巴瘤，牛皮癣和HIV感染的研究。

Peldesine (BCX 34) dihydrochloride is a potent, competitive, reversible and orally active purine nucleoside phosphorylase (PNP) inhibitor with IC 50 s of 36 nM, 5 nM, and 32 nM for human, rat, and mouse red blood cell (RBC) PNP, respectively. Peldesine dihydrochloride is also a T-cell proliferation inhibitor with an IC 50 of 800 nM. Peldesine dihydrochloride has the potential for cutaneous T-cell lymphoma, psoriasis and HIV infection research [1] [2] [3] [4].

Peldesine (BCX 34; 0-50 μM; 72 hours; Jurkat cells) could inhibit the T-cell proliferation completely at a concentration of less than 10 μM, in the presence of dGuo (10 μM). In contrast, the B-cell proliferation is not affected by Peldesine [1]. Peldesine (BCX 34) suppresses T-cell immune reaction in an IL-2-independent manner, and this means that Peldesine might affect a late phase rather than an early stage in T-cell activation [1]. Peldesine also, in the presence but not in the absence of deoxyguanosine, inhibits human leukemia CCRF-CEM T-cell proliferation with an IC 50 of 0.57 μM but not rat or mouse T-cell proliferation up to 30 μM [3]. Cell Viability Assay [1] Cell Line: Jurkat cells Concentration: 0-50 μM Incubation Time: 72 hours Result: In the presence of 10 μM dCuo, had a complete inhibitory effect for T-cell lines.
