Previously unreported15N labeled Azidothymidine (AZT) was prepared as an equimolar mixture of two isotopomers: 1‐15N‐AZT and 3‐15N‐AZT. Polarization decay of15N NMR signal was studied in high (9.4 T) and low (~50 mT) magnetic fields.15NT1values were 45 ± 5 s (1‐15N‐AZT) and 37 ± 2 s (3‐15N‐AZT) at 9.4 T, and 140 ± 16 s (3‐15N‐AZT) at 50 mT.15N‐AZT can be potentially15N hyperpolarized by several methods. These sufficiently long15N‐AZTT1values potentially enable hyperpolarizedin vivoimaging of15N‐AZT, because of the known favorable efficient (i.e., of the time scale shorter than the longest reported here15NT1) kinetics of uptake of injected AZT. Therefore, 3‐15N‐AZT can be potentially used for HIV molecular imaging using hyperpolarized magnetic resonance imaging.
