2,4-Bis(4-hydroxybenzyl)phenol Inhibits Heat Shock Transcription Factor 1 and Sensitizes Lung Cancer Cells to Conventional Anticancer Modalities

18.04.2014 | Taesook Yoon; Ga-Young Kang; Ah-Reum Han; Eun-Kyoung Seo; Yun-Sil Lee, Journal of Natural Products, 2014

Heat shock factor 1 (HSF1) is a transcription factor that regulates expression of heat shock protein (HSP) genes in response to stress. HSPs are expressed at high levels in a wide range of tumors. It has been reported that HSF1 and HSPs are associated closely in tumorigenesis. In the present ...

Diterpenoids from Croton laui and Their Cytotoxic and Antimicrobial Activities

15.04.2014 | Cui-Ping Liu; Jin-Biao Xu; Jin-Xin Zhao; Cheng-Hui Xu; Lei Dong; Jian Ding; Jian-Min Yue, Journal of Natural Products, 2014

Fourteen new diterpenoids including clerodane (1–12), labdane (13), and norlabdane (14) types, as well as nine known analogues were isolated from the aerial parts of Croton laui. Their structures were established on the basis of spectroscopic analysis, and that of crotonolide H (11) was confirmed ...

Voacamine Modulates the Sensitivity to Doxorubicin of Resistant Osteosarcoma and Melanoma Cells and Does Not Induce Toxicity in Normal Fibroblasts

10.04.2014 | Maria Condello; Dario Cosentino; Silvia Corinti; Gabriella Di Felice; Giuseppina Multari; Francesca Romana Gallo; Gi ..., Journal of Natural Products, 2014

In previous studies it has been demonstrated that the plant alkaloid voacamine (1), used at noncytotoxic concentrations, enhanced the cytotoxicity of doxorubicin and exerted a chemosensitizing effect on cultured multidrug-resistant (MDR) U-2 OS-DX osteosarcoma cells. The in vitro investigations ...
