A metabolite of Amifostine. | [Biological Activity]
wr-1065, a dephosphorylated metabolite of amifostine?(ethyol), can protect against the immediate and delayed effects of radiation exposure.wr-1065 can protect against zidovudine (azt) – induced genetoxicity. the lymphoblastoid cell line molt-3 cells were exposed to 0/10μm azt for 96h. in the first 24h 0/5?μm wr-1065 was added and cyt b was added in 76h in the cells, the viability of azt treated molt-3 cells did not altered.[1] moreover, in rko36 cell lines (derivative rko human colorectal carcinoma carrying a gfp-pcmv-egfp2xho), 4 mm final concentration (ec50) wr-1065 treatment for 30min immediately before irradiation showed protective effects against cell chromosomal damage and death induced by ionizing radiation and delayed genomic instability. but 40??m wr-1065 did not show immediate radio-protective effects in irradiated rko36 cells.[2] wr-1065 acts as radioprotective agents mainly through suppression of the homologous recombination pathway. in spd8 chinese hamster cell line, both 4 mm wr-1065 for 30min and 10 ?m for 24h significantly reduced the homologous recombination induced by 0.2 mm hydroxyurea for 24h or 100 nm camptothecin for 1h. while wr-1065 did not show its radioprotective effects in irradiated homologous recombination-deficient irs 1sf cells compared with homologous recombination-proficient cells aa8/cxr3(p＜0.05).[3]with spray drying technique using plga (polylactide co-glycolide) as the polymer matrix, wr-1065 were prepared into nanoparticles. 500mg/kg wr-1065/plga nanoparticles in which containing 21.7(w/w wr-1065) were administrated orally in mice to determined its radio-protective role. wr-1065plga nanoparticles treatment mice showed noteworthy higher 30-day survival, less bone marrow suppression and less intestinal injury compared non-treated control mice, indicated its significant radio-protective effects.[4] | [Biochem/physiol Actions]
WR-1065 is cytoprotective cell-permeable reactive oxygen species scavenger and p53 activator and re-activator. Recently shown to have antiretroviral activity and an active metabolite of Amifostine which selectively protects normal tissues from the damaging effects of anti-neoplastic radiation therapy. | [in vivo]
The results show that Amifostine thiol dihydrochloride (Amifostine thiol) attenuates the severity of 6-OHDA-induced catalepsy (P<0.001) when compare with 6-OHDA-lesioned rats. Also it has been observed that Amifostine thiol dihydrochloride improves catalepsy in dose dependent manner (P<0.001). Pretreatment with three different doses of Amifostine thiol dihydrochloride (20, 40 and 80 μg/2 μL/rat) for 3 days before 6-OHDA administration, significantly (P<0.001) elevates SOD activity and restores it to normal range compare with 6-OHDA lesioned rats[3]. | [storage]
