A new 5'-nucleotidase inhibitor named nucleoticidin was produced by Pseudomonas sp. YM-3229G. It was isolated from a fermentation broth by trichloroacetic acid extraction, ethanol precipitation and Dowex 1 and DEAE-52 column chromatography. It inhibited 5'-nucleotidase activity of snake venom and rat liver membrane. It also showed antitumor activity against solid type Sarcoma 180.
