It is one of the most important antitumor agents for clinical treatment of ovarian, breast non-small cell lung and prostate cancers. It is known that these types of cancer cells have high beta-glucuronides enzyme which can catalyze the hydrolysis of glucuronides. This is why the synthesis compounds which undergo glucuronidation come into question in the imaging and therapy of these cancer cells. The aim of current study is conjugation of glucuronic acid (G) to the starting substance PAC, labeling with I-131 and to perform its in vivo biological evaluation. Glucuronic acid derived paclitaxel compound [paclitaxel-glucuronide (PAC-G)] was labeled with I-131 using iodogen method. According to thin layer radio chromatography (TLRC) method, the radio-chemical yield of I-131-PAC-G was 84.30 +/- 7.40% (n = 10). The biodistribution of I-131-PAC-G in healthy female and male Wistar Albino rats has been investigated. Imaging studies on male Balb-C mice were performed by using the Kodak FX PRO in vivo Imaging System. The range of the breast/blood, breast/muscle; ovary/blood, ovary/muscle ratios is approximately between 1.29 and 11.34 in 240 min, and between 0.71 and 8.24 in 240 min for female rats. The prostate/blood and prostate/muscle ratio is between 1.94 and 6.95 in 30 min for male rats. All these experimental studies indicate that I-131-PAC-G may potentially be used in breast, ovary and prostate tissues as an imaging agent. Also it is thought that (131)-PAC-G bears a theraphy potential because of the I-131 radionuclide and can be improved with further investigations.en10.1524/ract.2012.1922info:eu-repo/semantics/closedAccessPaclitaxel (PAC)Paclitaxel-glucuronideI-131-paclitaxel-glucuronide (I-131-PAC-G)Article1005339345WOS:000305114100009Q1
