Synthesis and bioevaluation of a 177Lu-labeled unsymmetrical cationic porphyrin derivative as a tumor targeting agent
A cationic porphyrin derivative namely, 5-carboxymethyleneoxyphenyl-10,15,20-tri(p-N-methylpyridyl)porphyrin was synthesized and conjugated with a bi-functional chelating agent namely, p-NH2-benzyl-DOTA (p-aminob...

Neutral 99mTc(CO)3 complexes of “clicked” nitroimidazoles for the detection of tumor hypoxia
In the present work, three neutral 99mTc(CO)3 complexes of nitroimidazole were synthesized and their potential to detect tumor hypoxia is evaluated in vivo. Triazole derivatives of 2-, 4- and 5-nitroimidazole wer...

Radiosynthesis and Bioevaluation of [68Ga]-Labeled 5,10,15,20-Tetra(4-methylpyridyl)-porphyrin for Possible Application as a PET Radiotracer for Tumor Imaging
Porphyrins have inherent ability to localize preferentially in tumor lesions. Cationic porphyrins are readily water soluble and reported to exhibit strong DNA-binding capabilities. Therefore, attempt has been ...

Synthesis and evaluation of a phenylbenzothiazole-based 99mTc(CO)3-radiotracer for possible application in imaging of β-amyloid plaques in Alzheimer’s disease
The 2-phenyl benzothiazole pharmacophore is known to have high affinity for amyloid beta (Aβ) and is therefore derivatized, to [N-(4′-benzothiazol-pyridin-2-yl-methyl-amino)-acetic acid (BTPAA)] for radiolabeling...
