The synthesis and in vitro activity of 7 beta-(2-aminopyridyl-2-alkoxyiminoacetamido)cephalosporins with various substituents at the 3-position are described. The effects of substitution pattern on the pyridine ring, oxime substituent and 3-substituent were studied as a function of the MIC values. Of these various kinds of derivatives, 7 beta-[2-(2-aminopyridin-6-yl)-2-alkoxyiminoacetamido]cephalo sporins exhibited significantly higher activity against most of micro-organisms.
