Abstract

Chemotherapy is one of the main treatments used to combat cancer. A great number of antitumor compounds are natural products or their derivatives, mainly produced by microorganisms. In particular, actinomycetes are the producers of a large number of natural products with different biological activities, including antitumor properties. These antitumor compounds belong to several structural classes such as anthracyclines, enediynes, indolocarbazoles, isoprenoides, macrolides, non-ribosomal peptides and others, and they exert antitumor activity by inducing apoptosis through DNA cleavage mediated by topoisomerase I or II inhibition, mitochondria permeabilization, inhibition of key enzymes involved in signal transduction like proteases, or cellular metabolism and in some cases by inhibiting tumor-induced angiogenesis. Marine organisms have attracted special attention in the last years for their ability to produce interesting pharmacological lead compounds.

  • Of actinomycete-derived compounds, 75% were derived from Streptomyce whereas 25% were derived from rare actinomycetes.

    “Of these actinomycete-derived compounds, 75% were derived from Streptomyce whereas 25% were derived from rare actinomycetes [125,126].”

    From Marine Natural Products: A Source of Novel Anticancer Drugs (2019) · cites this paper as [125]

    The Introduction (page unavailable) reports over 10,000 actinomycete-produced compounds, around 7,600 of them from Streptomyces—approximately 75%. It does not identify the remaining approximately 25% as coming specifically from rare actinomycetes. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Actinomycete-isolated secondary metabolites account for ca. 45% (~10,000 compounds) of the total known anti-microbial metabolites.

    “Actinomycete-isolated secondary metabolites account for ca. 45% (~10,000 compounds) of the total known anti-microbial metabolites.”

    From Marine Natural Products: A Source of Novel Anticancer Drugs (2019) · cites this paper as [125]

    The Introduction reports that actinomycetes produce over 10,000 compounds, representing 45% of all bioactive microbial metabolites discovered. It does not give those figures for antimicrobial metabolites specifically; it says only that many of the compounds are antibiotics. Page numbers are not provided in our copy. (LLM, conf=0.90)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
