原始语种摘要: Abstract(#br)SSR180575 (7‐chloro‐ N , N, 5‐trimethyl‐4‐oxo‐3‐phenyl‐3,5‐dihydro‐4 H ‐pyridazino[4,5‐ b ]indole‐1‐acetamide) is the lead compound of an original pyridazinoindole series of potent and highly selective TSPO (peripheral benzodiazepine receptor) ligands. Isotopic labeling of SSR180575 with the short‐lived positron‐emitter carbon‐11 (T1/2: 20.38 min) at its 5‐methylpyridazino[4,5‐ b ]indole moiety as well as at its N,N ‐dimethylacetamide function by methylation of the corresponding nor ‐analogues was investigated. Best results in terms of radiochemical yields and purities were obtained for the preparation of [ indole‐N‐methyl‐ 11C]SSR180575, where routine production batches of 4.5–5.0 GBq of radiochemically pure (>99%) i.v. injectable solutions (specific...
