Malinka, W. published the artcileSynthesis and preliminary screening of derivatives of 2-(4-arylpiperazin- 1-ylalkyl)-3-oxoisothiazolo[5,4-b]pyridines as CNS and antimycobacterial agents, Application In Synthesis of 87179-40-6, the publication is Pharmazie (2000), 55(6), 416-425, database is CAplus and MEDLINE.
Isothiazolopyridines, e.g. I (X = S, SO2; X1 = CO, CH2CH2, CH2CH2CH2; R = H, 3-Cl, 3-CF3, 2-MeO), were prepared that possess a side chain at the isothiazole ring typical, among others, for trazodone or NAN-195. Representatives of these novel isothiazolopyridines were examined for acute toxicity and in several commonly used CNS tests in mice and for arterial blood pressure in rats. Three of the five compounds tested showed significant analgesic activity. The most active compound, I (X = S; X1 = CH2CH2; R = 3-Cl) exhibited analgesic action in the writhing test in a dose 1/1280 of LD50 (LD50 = 1135.5 mg/kg) after administration i.p. to mice. Addnl., the compounds described here and related isothiazolopyridines obtained previously were evaluated against Mycobacterium tuberculosis H37Rv at 12.5 μg/mL in in vitro assays. Seven of the nineteen compounds tested showed 100% inhibition of that mycobacterium.
