Macrocyclic chelators (I) for chelation of alpha-emitting radiometal ions, such as actinium-225 are provided. Also provided are radiometal complexes containing an alpha-emitting radiometal ion bound to the macrocyclic chelator via coordinate bonding, and radioimmunoconjugates containing the radiometal complexes covalently linked to a targeting ligand, such as an antibody or antigen binding fragment thereof. The radioimmunoconjugates can be produced by click chemistry reactions. Methods of using the radiocomplexes and radioimmunoconjugates for selectively targeting neoplastic cells for radiotherapy and for treating neoplastic diseases and disorders are also described.

Provided are a novel low-molecular-weight compound that suppresses production of induction type MMPs, particularly MMP-9, rather than production of hemostatic type MMP-2, as well as a prophylactic/therapeutic drug for autoimmune diseases or osteoarthritis. An amide derivative represented by the following formula (I)
wherein each symbol is as defined in the specification, or a pharmacologically acceptable salt thereof.

Reaction of primary and secondaryalcohols with tetrahydrofuran and a catalytic amount of 1-tert-butylperoxy-1,2-benziodoxol-3(1H)-one in the presence of carbontetrachloride at 50 °C provides an efficient method for protecting the hydroxy group as 2-tetrahydrofuranyl ethers.
