Two new 2-(2-phenylethyl)chromone derivatives (1–2), comprising 5,6,7,8-tetrahydro-2-(2-phenylethyl)chromone and benzylacetone moieties, together with one new 2-(2-phenylethenyl)chromone (3) were isolated from the ethyl acetate extraction of agarwood originated from Gyrinops salicifolia Ridl. All structures were unambiguously elucidated on the basis of 1D and 2D NMR spectra as well as by HRESIMS data. All isolated compounds were tested for acetylcholinesterase (AChE) inhibitory activity and cytotoxic activity against human myeloid leukemia cell line (K562). However, none of the compounds displayed AChE inhibitory activity at a concentration of 50 µg mL−1 or cytotoxic activity against K562 cell line.

Cancer is a major public health burden in both developed and developing countries. Plant-derived compounds have played an important role in the development of useful anti-cancer agents. The current study was designed to evaluate the cytotoxic activity of chemical compounds from the stem bark of Styrax obassia. Seven known compounds (1–7) were isolated and identified. Compound 2 exhibited cytotoxic activity against the breast cancer cell line MCF-7 with an IC50 of 27.9 μM, followed by the human cervical cancer cell line Hela with an IC50 of 23.3 μM, and the human promyelocytic leukemia cell line HL-60 with an IC50 of 47.8 μM. Compound 7 exhibited cytotoxicity against Hela cells with an IC50 of 16.8 μM, followed by MCF-7 cells with an IC50 of 53.5 μM. This is the first study to investigate the significant anti-tumor properties of isolated compounds from the stem bark of S. obassia.

The present study describes the cytotoxic properties of a series of 15 cyclic imides observed against different endothelial cells and K562 leukemic cells. Initially, eight structurally unrelated compounds were evaluated against cultured bone marrow endothelial cells (BMEC) and human umbilical vein endothelial cells (HUVEC). Only two imides showed cytotoxic activity at 10 μm. In continuation of our screening, eight compounds, structurally related to the compound with the higher cytotoxic activity, were assayed against endothelial cells and the K562 leukemic cell line. All of these new compounds except two exhibited cytotoxic and antiproliferative activities at concentrations below 10 μm against BMEC and HUVEC, respectively. The K562 leukemia cell line was only affected by concentrations of 100 μm. Preliminary SAR analysis indicated that the cytotoxic activity of these compounds was related to the presence of a planar imide ring directly bound to an aromatic ring.

Gold nanoparticles (AuNP) are potentially developed as nanomedicine because AuNP is easily synthesized, functionalized, and biocompatible. With gum arabic as a stabilizer, vincristine was conjugated with gold nanoparticles. As a reducing agent, it used 0.02 M Natrium Boro Hidrat (NaBH4)  solution. Gold nanoparticles (AuNP) coated with conjugated gum Arabic (GA) and vincristine (VCR) were successfully synthesized and characterized. The conjugation of GA-VCR and AuNP displayed a narrow hydrodynamic particle size distribution with average size < 100 nm by TEM and  PSA (particle size analyzer). We investigated the cytotoxic activity of conjugated vincristine-gum arabic-gold nanoparticle by tetrazolium salt assay (MTT) using cancer cell line CCR-CEM. Cytotoxic activity of conjugated VCR-GA-AuNP before and after purification by Size Exclusion Chromatography (SEC), against leukemia cell line CCRF-CEM, was described by IC50 value. All formulation had a cytotoxic of activity with IC50 <20 μg/ml. The IC50 of samples against CCRF cell line were 1,026 μg/mL and  2,607 ug/mL, respectively.

Abstract The Eleutherococcus species including 40 species native to Asia are medicinal plants widely used in traditional medicine. Some of these species are cultivated at the botanical gardens in Europe. On the basis on our earlier studies it was concluded that the extracts of analyzed species act as antioxidants, inhibitors of MMPs, and cytotoxic against Jurkat 45 leukemia cell line. In this study, the anti-leukemic potential of roots and leaves from six Eleutherococcus species cultivated in Poland was determined. The in vitro cytotoxic activity towards human promyelotic leukemia cell line HL60 using trypan blue assay was evaluated. The induction of apoptosis in stimulated leukemia cells was determined by AnnexinV method. Morphological changes in treated cells were observed by microscopic investigations. The results showed that ethanolic extracts from the roots and the leaves of E. senticosus, E. setchuensis, E. sessiliflorus, E.gracilistylus, E. henryi and E. divaricatus exhibit cytotoxic effect towards leukemic HL60 cells. The received IC50 values for roots ranged from 49- 208 μg/mL and for the leaves from 116-518 μg/mL. The ethanol extract from the roots of E. divaricatus showed the highest cytotoxic and proapoptotic effect on HL60 human lymphoid leukemia cell line.
