Chemistry on Their Way into a New Century

چکیده
68Ga faces a renaissance initiated by the development of new 68Ge/68Ga radionuclide generators, sophisticated 68Ga radiopharmaceuticals, preclinical research and state-of-the-art clincial diagnoses via positron emission tomography/computed tomography (PET/CT). A new type of 68Ge/68Ga generator became commercially available in the first years of the 21st century, with eluates based on hydrochloric acid. These generators provided ‘cationic’ 68Ga instead of ‘inert’ 68Gacomplexes, and opened new pathways of MeIII radiopharmaceutical chemistry. The last decade has seen a 68Ga rush. Increasing interest in generator-based 68Ga radiopharmaceuticals in diagnostic applications has been accompanied by its potential use in the context of diease treatment planning, made possible by the inherent option expressed by theranostics. However, widespread acceptance and clinical application requires optimization of 68Ge/68Ga generators both from chemical and regulatory perspectives.

Half-Century Journey from Synthetic Organic Chemistry to Mathematical Stereochemistry through Chemoinformatics
My half-century journey started from synthetic organic chemistry. During the first stage of my journey, my interest in stereochemistry was initiated through the investigation on the participation of steric effects in reactive intermediates, cylophanes, strained heterocycles, and organic compounds for photography. In chemoinformatics as the next stage of the journey, I proposed the concept of im...
