IDENTIFICATION OF A BACTERIAL GROWTH INHIBITOR FROM HELA CELLS: A KETOALDEHYDE

Brian G Sparkes 1,2,*, C Paul Kenny 1,2
PMCID: PMC223322  PMID: 5264149

Abstract

The growth-inhibiting factor found earlier in human cell cultures appeared to be a ketoaldehyde. An infrared spectral study of 2,4-dinitrophenylhydrazine derivatives suggested that the ketoaldehyde was 4-hydroxy-2-ketobutyraldehyde. The compound, when synthesized, gave the same DNPH derivatives as the natural substance.
