Disease relevance of CUCURBITACIN R - DATISCA PRINCIPLE B

  • The subfraction (F-III) from CH2Cl2 extract and compounds isolated as cucurbitacin B and E also inhibited carrageenan-induced edema [1].
 

High impact information on CUCURBITACIN R - DATISCA PRINCIPLE B

  • Cucurbitacin B (cucB) prevents stimulation by 20E of an ecdysteroid-responsive reporter gene in a transfection assay [2].
  • A new sulfated cucurbitacin, cucurbitacin B 2-sulfate (1) and a new cucurbitacin glucoside, cucurbitacin G 2-O-beta-D-glucopyranoside (2) together with two known cucurbitacin glucosides, arvenin I and arvenin III were isolated from the root bark of Helicteres angustifolia [3].
  • Cucurbitacin B 2-Sulfate and Cucurbitacin Glucosides from the Root Bark of Helicteres angustifolia [3].
  • Cucurbitacin B (1) imparts a bitter taste to the flesh of the fungus; however, it occurs in the fruiting bodies mainly esterified as tasteless fatty acid esters 2a-c. In vitro growth inhibitory effects of compounds 1-4 on proliferation of four different human tumor cell lines (A549, CAKI-1, HepG2, MCF-7) were evaluated by using a 1-day MTT assay [4].
  • The F-DCM was also able to prevent PGE2 formation in exsudate leakage induced by carrageenan, as well as Cucurbitacin B, its active principle [5].
