The synthesis of the quinolone, 7-ethyl-3-methyl-4,7-dihydro-4-oxoisothiazolo[5,4-b]pyridine-5-carboxylic acid 4 was accomplished utilizing the Gould-Jacobs dependent route. The compound had very weak in vitro activity as compared to nalidixic acid versus E. coli, P. aeruginosa, K. pnuemoniae, S. aureus and P. mirabilis. 相似文献
