Thai/Lanna medicinal plant recipes have been used for the treatment of several diseases including liver cancer. In this study, methanolic extracts (MEs) of 23 plants were tested for antiproliferative activity on human hepatoma cell line (Hep G2) by the sulforhodamine B (SRB) assay. Nine MEs with potent antiproliferative activity (IC50 < 100 µg/mL) were obtained and further semipurified by liqui...
Synthesis of a new series of pyrimidinyl-imidazo[2,1-b]thiazole derivatives is described. Their antiproliferative activity against A375 human melanoma cell line was tested and the effect of substituents on the pyrimidinyl ring side chain was investigated. The biological results indicated that most of the newly synthesized compounds showed moderate activity against A375, compared with Sorafenib....
BACKGROUND Haematoxylum brasiletto is a tree that grows in Central America, commonly known as "Palo de Brasil," which is used in the traditional medicine for the treatment of cancer and gastric ulcers. OBJECTIVE The aim of this study was to isolate the compounds responsible for antiproliferative activity of H. brasiletto. MATERIALS AND METHODS A bioassay-guided fractionation of ethanol extr...
In our continuing structure-activity relationship study of a new class of erythromycin A (EM-A) derivatives with antiproliferative activity, a new series of de(N-methyl) EM-A dimers jointed by a four-atom linker, -CH2CH = CHCH2-, were prepared and their antiproliferative activity against three human tumor cell lines was evaluated by MTT assay. The most active EM-A dimer, compound 1b, that carry...
Several novel N-(9-oxo-9H-xanthen-4-yl)benzenesulfonamides derivatives were prepared as potential antiproliferative agents. The in vitro antiproliferative activity of the synthesized compounds was investigated against a panel of tumor cell lines including breast cancer cell lines (MDA-MB-231, T-47D) and neuroblastoma cell line (SK-N-MC) using MTT colorimetric assay. Etoposide, a well-known anti...
The cytotoxic chloroform fraction of Euphorbia aellenii afforded two cycloartane type triterpenes — cycloart-25-en-3,24-diol (1) and 24-methylene-cycloartan-3-ol (2) — for the first time from this plant. Preparation of cycloartane derivatives, 3, 24-O-diacetyl-cycloart-25-en as compound 3 and 3-O-acetyl-24-methylene-cycloartan (4) were conducted by acetylating of 1 and 2, respectively. The ...
background: functional defects in mitochondria are involved in the induction of cell death in cancer cells. the process of programmed cell death may occur through the mechanisms of apoptosis. several potential lead molecules such as camptothecin (cpt) and its analogues have been isolated from plants with anticancer effect. the aim of the present study was to understand the necrotic effect versu...
