It has weak anti-tumor cell activity and moderate anti-aspergillus and fusarium activity, but has no effect on yeast. Dorrigocin B has stronger antitumor and antifungal activities than Dorrigocin A. It can restore the morphology of RAS-deformed NIH/3T3 cells from the deformed phenotype to the normal phenotype.
