Cytotoxic and Antitumor Constituents in Pericarps ofMallotus japonicus

Planta Medica, 1990
A variety of phloroglucinol derivatives isolated from the pericarps of Mallotus japonicus were assessed for growth inhibiting activity against human larynx (HEp-2) and lung (PC-13) carcinoma cells as well as mouse B16 melanoma, leukemia P388, and L5178Y cells. Most of these derivatives were proved to be significantly cytotoxic in culture.

Studies on Cytotoxic Constituents in Pericarps of Mallotus japonicus, Part II

Journal of Natural Products, 1985
Two new phloroglucinol derivatives, mallotolerin (8) and mallotochromanol (9), were isolated from the cytotoxic fraction of the pericarps of Mallotus japonicus. The new derivatives were identified as 3-(3-methyl-2-hydroxybut-3-enyl)-5-(3-acetyl-2,4-dihydroxy-5-me thy l-6- methoxybenxyl)-phlorbutyrophenone (8) and 8-acetyl-5,7-dihydroxy-6-(3-acetyl-2,4 ...

Phloroglucinol derivatives from fruits of Mallotus japonicus

Phytochemistry, 1983
Abstract Two new rottlerin-like phloroglucinol derivatives were isolated from the fruits of Mallotus japonicus and identified by chemical and spectral data as 3-(3, 3-dimethylallyl)-5-(3-acetyl-2, 4-dihydroxy-5-methyl-6-methoxybenzyl)-phloracetophenone and 3-(3-methyl-2-hydroxybut-3-enyl)-5-(3-acetyl-2, 4-dihydroxy-5-methyl-6-methoxybenzyl ...

Further phloroglucinol derivatives in the fruits of Mallotus japonicus

Phytochemistry, 1985
Abstract Two new rottlerin-like phloroglucinol derivatives were detected from the fruits of Mallotus japonicus and identified as 3-(3,3-dimethylallyl)-5-(3-acetyl-2,4-dihydroxy-5-methyl-6-methoxybenzyl)-phlorobutyrophenone and -phloroisobutyrophenone by spectral studies.

Structure and biosynthesis of malloprenols from Mallotus japonicus

Phytochemistry, 1980
Abstract The mallo prenol isolated from the leaves of Mallotus japonicus was elucidated to be a mixture of (2Z,6Z, 10Z, 14Z, 18Z, 22Z, 26E, 30E, 34E)-3,7,11,15,19,23,27,31,35,39-decamethyl-2,6,10,14,18,22,26,30,34,38-tetracontadecaen-1-ol and its C45- and C55-homologues and not the previously reported structure.

Glucosylation of salicylic acid by cell suspension cultures of Mallotus japonicus

Plant Cell Reports, 1990
Salicylic acid was converted into its O-glucoside when administered to cell suspension cultures of Mallotus japonicus. The efficiency of the glucosylation was highest in the cells grown in Linsmaier-Skoog medium containing 1 μM 2,4-dichlorophenoxy-acetic acid at any scale of culture (7 ml - 3 1).

ent-Labdane Diterpenes from the Stems of Mallotus japonicus

Journal of Natural Products, 2013
Eight new ent-labdane diterpenoids, mallonicusins A-H (1-8), were isolated from the stems of Mallotus japonicus. Their structures, including the absolute configurations, were determined by extensive analyses of spectroscopic data and the ECD spectra of the Pr(FOD)₃ complex of substrates in CCl₄. The absolute configuration of compound 1 was confirmed by

Antitumor-Promoting Activity of Mallotojaponin, a Major Constituent of Pericarps of Mallotus japonicus

Oncology, 2009
Mallotojaponm, a major constituent of the pericarps of Mallotus japonicus (Euphorbiaceae), inhibited the action of tumor promoter in vitro and in vivo; it inhibited tumor promoter-enhanced phospholipid metabolism in cultured cells, and also suppressed the promoting effect of 12-O-tetradecanoylphorbol-13-acetate on skin tumor formation in mice initiated
