Structural revision of sulfated polysaccharide B-1 isolated from a marine Pseudomonas species and its cytotoxic activity against human cancer cell lines

Abstract

The structure of a sulfated polysaccharide (B-1) isolated and purified from the culture filtrate of marine Pseudomonas sp. WAK-1 was revised to have a repeating unit as follows: -2)-beta-D-Galp(4SO4)(1-4)[beta-D-Glcp(1-6)]-beta-D-Galp(3SO4)(1-. B-1 was evaluated for anticancer activity using a human cancer cell line panel coupled with a drug sensitivity database. The average B-1 concentration required for 50% growth inhibition against the panel of 39 cell lines was 63.2 micro g/ml. Among the cancer cell lines tested, high sensitivities to B-1 were observed in central nervous system cancer and lung cancer cell lines. The COMPARE analysis revealed that the differential growth inhibition pattern of B-1 had no significant correlation with those of more than 200 standard compounds, most of which were anticancer drugs and different types of inhibitors. This lack of similarities in the cytotoxic patterns appears to reflect previously unrecognized biological properties of B-1. It was revealed that B-1 induced apoptosis in U937 cells, as shown by cell morphology and internucleosomal DNA fragmentation.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A sulfated polysaccharide isolated from marine Pseudomonas spp. (B-1) filtrate induced apoptosis of human leukaemic cells (U937).

    “A sulfated polysaccharide isolated from a marine Pseudomonas spp. (B-1) filtrate induced apoptosis of human leukaemic cells (U937) [172], whereas pancreatic islet carcinoma apoptosis was observed with PI-88, a sulfated oligosaccharide [173].”

  • Polysaccharide B1 from the marine Pseudomonas sp. demonstrated cytotoxicity against tumor cells, being more active to the central nervous system and lung cancer cell lines.

    “Polysaccharide B1 from the marine Pseudomonas sp. has repeating units as -2)-β-d-Galp(4-sulfate)(1,4)[β-d-Glcp(1,6)]-β-d-Galp(3-sulfate)(1- and demonstrated cytotoxicity against tumor cells, being more active to the central nervous system and lung cancer cell lines.”
  • Polysaccharide B1 from the marine Pseudomonas sp. induced apoptosis in U937 cells.

    “It induced apoptosis in U937 cells [126].”

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.
