ABSTRACT A cardenolide glycoside, 3 beta-O-(2'-O-acetyl-l- thevetosyl)-15(14-->8)-abeo-5 beta-(8R)-14-oxo-card-20(22)-enolide (2'-O-acetyl cerleaside A), was isolated from a methylene chloride extract of the seeds of Cerbera odollam, together with four known compounds: cerleaside A, 17 alpha-neriifolin, 17 beta- neriifolin and cerberin. Their structures were elucidated by spectroscopic methods. All compounds except cerleaside A exhibited cytotoxic activities against oral human epidermoid carcinoma (KB), human breast cancer cell (BC) and human small cell lung cancer (NCI-H187).

    ABSTRACT: The toxicity of the sea mango (Cerbera manghas L.) is well known. The plant is ranked as one of the deadliest of the southern Asian coastline. Cardenolidic heterosides are responsible for the cardiotoxicity of trees of the Cerbera genus. We have identified and determined the concentration of the principal glycosidic steroids present in the seeds of sea mangos (Thailand). Drug screening of an extract of the seeds was carried out using ultra-high performance liquid chromatography coupled to photodiode array detection and mass spectrometry (UHPLC-PDA-MS) with quantification at 219nm. Identification was confirmed by UHPLC-HRMS. Deacetyltanghinin (m/z 549.3055±2ppm), neriifolin (m/z 535.3259±2ppm), tanghinin (m/z 591.3169±2ppm) and cerberin (577.3375±2ppm) were the most abundant glycosidic steroids present in the sea mango seeds. A seed of the dried ripe fruit had concentrations of 1209.1, 804.2, 621.4 and 285.9μg/g, respectively. A seed of the fresh unripe fruit had concentrations of 49.4, 47.0, 3.5 and 2.3μg/g.

    ABSTRACT: Objective To investigate the efficacy of 17 ethnomedicinal plants belonging to Apocynaceae family used in combination with 16 conventional antibiotics against non-multidrug resistant-, multidrug resistant (MDR)-, and extensive drug resistant (XDR) Acinetobacter baumannii (A. baumannii). Methods Antibacterial activity and resistance modifying ability of 272 combinations were determined by growth inhibition assays and further confirmed by time-kill assay. Results Among the combinations of the antibiotics with Apocynaceae ethanol extracts on this pathogen, 15 (5%) had synergistic effects, 23 (8%) had partial synergistic effects and 234 (86%) had no effects. Synergistic activity was observed mostly when the Apocynaceae extracts were combined with rifampicin or cefazolin. Interestingly, 10 out of 17 combinations between the extracts and rifampicin displayed synergistic or partial synergistic behaviors. Holarrhena antidysenterica extract was additionally tested to restore rifampicin activity against clinical isolates of MDR and XDR A. baumannii. With respect to total or partial synergy, 70% was XDR A. baumannii isolates and 66% was MDR A. baumannii isolates. Conclusions Holarrhena antidysenterica extract clearly demonstrated the ability to restore rifampicin activity against both A. baumannii ATCC19606 and clinically isolated A. baumannii. Additional studies examining its active principles as well as mechanisms of actions such as the effects on efflux pumps and outer membrane permeability alterations are recommended.

    ABSTRACT: We report the isolation of two known iridoid glucosides theviridoside (1) and theveside (2) from the aqueous extract of leaves of Cerbera odollam and semi-synthetic derivatisation of theveside prepared in a single step under protection group-free conditions. Derivatives 2a-j were evaluated for cytotoxicity towards five human cancer cell lines of different origins, namely SKBR3 (breast), HeLa (cervical), A375 (skin), HepG2 (liver) and HCT-116 (colon), and IC50 values were determined. Derivatives 2b and 2h exhibited moderate cytotoxicity against HCT-116 and A375 cell lines, respectively.
