The present invention relates to new synthetic methods for preparing 2-methoxyisobutylisonitrile and metal isonitrile complexes, such as tetrakis(2-methoxyisobutylisonitrile)copper(I) tetrafluroroborate, which are used in the preparation of technetium (
99m
Tc) Sestamibi, and novel intermediate compounds useful in such methods.

Discovery of N-{5-[3-(3-hydroxypiperidin-1-yl)-1,2,4-oxadiazol-5-yl]-4-methyl-1,3-thiazol-2-yl}acetamide (TASP0415914) as an orally potent phosphoinositide 3-kinase γ inhibitor for the treatment of inflammatory diseases
Class I phosphoinositide 3-kinases (PI3Ks), particularly PI3K gamma, have become attractive drug targets for inflammatory and autoimmune disorders such as rheumatoid arthritis. Herein, we describe the synthesis and the structure-activity relationships (SAR) of a series of 2-amino-5-oxadiazolyl thiazoles, culminating in the identification of 8j (TASP0415914), an orally potent inhibitor of phosphoinositide 3-kinase gamma (PI3K gamma). TASP0415914 demonstrated good potency in a cell-based assay and, furthermore, exhibited in vivo efficacy in a collagen induced arthritis (CIA) model in mice after oral administration.
