Description:

Jatropholone B shows antiproliferative activity against cancer cell lines. It also has gastroprotective activity in preventing the gastric lesions in mice.

In vitro:

Planta Med. 2009 Nov;75(14):1520-2.

Antiproliferative activity of the diterpenes jatrophone and jatropholone and their derivatives.[Pubmed: 19562659 ]

The antiproliferative activity of the diterpenes jatropholone A and B, 16 semi-synthetic derivatives thereof, and that of jatrophone and its three derivatives was assessed on human cell cultures.
METHODS AND RESULTS:
The cells used comprised normal lung fibroblasts (MRC-5), gastric adenocarcinoma (AGS), leukemia (HL-60), lung cancer (SK-MES-1), and bladder carcinoma (J82). Jatropholone A ( 1) was inactive against all the tumor cell lines; however, its acetylation rendered a compound with antiproliferative activity. The epimeric Jatropholone B ( 8) was active against all the cancer cell lines, and its derivatives presented different effects on the selected cell lines.
CONCLUSIONS:
While jatrophone ( 19) showed strong anticancer activity, its derivatives 9beta,13alpha-dihydroxyisabellione and 13alpha-hydroxy-9 beta-acetoxyisabellione were less active.

In vivo:

Gastroprotective effect and cytotoxicity of semisynthetic jatropholone derivatives.[Pubmed: 17691058]

The gastroprotective effect of the diterpenes jatropholone A, Jatropholone B and 16 semisynthetic derivatives was assessed in the HCl/ethanol-induced gastric lesion model in mice and the cytotoxicity was determined towards fibroblasts and AGS cells.
METHODS AND RESULTS:
In a dose-response study, Jatropholone B reduced gastric lesions by 65% at 6 mg/kg and jatropholone A by 54% at 100 mg/kg. The Jatropholone B derivatives 9 - 14 and the compounds 15 - 18 were compared at a single oral dose of 25 mg/kg while the jatropholone A derivatives 2 - 7 were assessed at 100 mg/kg. A decrease in gastroprotective activity was observed for the ether as well as for the ester derivatives of Jatropholone B. The methyl and propyl ethers of jatropholone A were more gastroprotective than the natural product. The placement of an additional methyl group at C-2 in the Jatropholone B derivatives led to a loss of selectivity, the methyl and propyl ethers lack a gastroprotective effect. Jatropholone B was not toxic towards AGS cells and fibroblasts. Jatropholone A was active only against AGS cells. The gastroprotective effect of the epimeric jatropholones was selective showing a higher effect for Jatropholone B.
CONCLUSIONS:
These results further support that the stereochemistry of the methyl group at C-2 in the jatropholones plays a relevant role in preventing the gastric lesions in mice. The compounds 3, 5 - 7, 10 and 12 - 18 are described for the first time.
