Synthesis and Biological Activity of 4-(Sulphonamidomethyl)coumarins
Hanmantgad, Hrikant S.,Kulkarni, Manohar V.,Patil, Vemanna D.
, p. 459 - 461 (2007/10/02)
Various sulphanilamidomethylcoumarins (III a-w) have been synthesised by a four-step route.These sulphonamides have been characterised by their spectral data and some of them show better antibacterial activity against Staph. aureus and Esch. coli than the standard (sulphanilamide).Structure activity relationship has also been studied.
