Abstract: In the present paper, the synthesis of 11C-labeled Kendine 91 (a HDAC inhibitor which has shown in vitro and in vivo activity in HCT 116 and MOLT 4 human cancer cell lines) is described for the first time. The radiosynthesis has been approached by reaction of the non-radioactive precursor 6-((3-(4-hydroxyphenyl)-5-phenyl-1H-pyrrole-2-carboxamide))hexanehydroxamic acid with [11C]CH3I in basic media. Despite the presence of more than one reactive site in the chemical structure of the precursor, acceptable radiochemical yield (8.2±2.1%, decay corrected to the end of bombardment), specific activity (28.2±9.4 GBq/μmol) and radiochemical purity values (>95%) were obtained in reasonably short preparation times (∼40 min). Despite the moderate radiochemical yield, final radioactivity and radioactivity concentration values (1.8±0.3 GBq and 180 MBq/ml, respectively) should be sufficient for putative in vivo studies in animals.
