Abstract: The present invention is based on the discovery that certain fermentation products of the marine actinomycete strains CNB392 and CNB476 are effective inhibitors of hyperproliferative mammalian cells. The CNB392 and CNB476 strains lie within the family Micromonosporaceae, and the generic epithet Salinospora has been proposed for this obligate marine group. The reaction products produced by this strain are classified as salinosporamides, and are particularly advantageous in treating neoplastic disorders due to their low molecular weight, low IC50 values, high pharmaceutical potency, and selectivity for cancer cells over fungi.

Abstract: The present invention provides methods for the isolation of a new group of actinomycetes and for the identification of members of this group based on characteristic nucleotide sequences and phylogenetic analyses. This group is phylogenetically distinct from all other known actinomycetes and represents a novel genus that includes multiple new species. Members of this group can be recognized by signature MAR2 nucleotides present in their 16S rRNA gene sequences and by standard phylogenetic treeing methods.

Abstract: The invention is a group of compounds named halovirs with antiviral activity that are structurally related to compounds isolated from a marine fungus CNL240. Halovirs are comprised of a short, amphipathic helical peptide with an extended lipid moiety on the N-terminal end of the peptide. The halovirs have demonstrated activity against herpes simplex virus, types I and II.
