five flavonoid glycosides were isolated from the n-butanol soluble fraction of the ethanolic extract of rapistrum rugosum and their structures were assigned from 1h- and 13c-nmr spectra (dept) with 2d nmr as quercetin-3-o-α-l-rhamnopyranoside (1), quercetin-3-o-β-d-xyloside (2), quercetin, 3-o-α-l-arabinopyranoside,7-o-α-l-rhamnopyranoside (3), kaempferol 3-o-α-l-arabinopyranoside, 7-o-α-l-rham...

In vitro studies were carried out to evaluate the cytotoxic potential of the ethanolic and aqueous extracts of Luffa acutangula against human neuronal glioblastoma cells (U343) and human lung cancer cells (A549). Screening of these extracts was done using the brine shrimp lethality bioassay, MTT assay and SRB assay. The results showed the significant decrease of the viability of the cells in a ...

BACKGROUND The plant Launaea procumbens belongs to the family Asteraceae and traditionally used in the treatment rheumatism, kidney, liver dysfunctions and eye diseases. In the present study Phytochemical analysis and fractions of methanolic extract of L. procumbens leaves were tested in vitro for their cytotoxicity. OBJECTIVES Phytochemical analysis and cytotoxic activity of methanolic extra...

Acetylated betulinic acid ( BA ) was converted into mono-substituted benzylamides 2 – 14 . Screening in SRB assays showed them as cytotoxic for a variety of different human tumor cell lines. While parent not within the limits assay (cut-off 30 ​μM), target amides were cytotoxic. Their bioactivity well their cell/non-tumor selectivity depended on substitution pattern aromatic ring. The most acti...

Atranorin 1, Usnic acid 2, and D-Arabinitol 3 were isolated from Usnea aciculifera by extensive column chromatography. The structures elucidated based on the comprehensive spectral analysis including FT IR, GC MS, ESI 13C NMR, 1H NMR. compounds evaluated for their cytotoxic activity against LN-229 glioblastoma cancer cell line performing Sulforhodamine B assay (SRB). 2 showed strong with an IC5...

BACKGROUND Anisochilus carnosus (L.f.) wall (Lamiaceae), an annual herb which grows at high altitude is used extensively in folk medicine for the treatment of ailments such as gastric ulcer and skin diseases. The aim of our study was to evaluate the anticancer activity of different extracts of the leaves of A.carnosus. An attempt was also made to estimate the luteolin content in different extra...

Four sorbicillinoids (1-4) and seven bisorbicillinoids (5-11), including two new compounds, 6-demethylsorbicillin (1) and 10,11-dihydrobisvertinolone (6), were isolated from a marine-derived fungus Trichoderma sp. Their cytotoxic activities against HL-60 cell line were evaluated by Sulforhodamine B (SRB) assay method and flow cytometric analysis.

Some 2-thiouracils and fused 2-thiouracils were evaluated for their cytotoxicity study .The synthesized compounds were tested for their cytotoxicity effects towards (CaCo-2) cancer cell line using SRB assay. The results showed that compound 1b displayed promising cytotoxic activity and found to be more potent than standard, doxorubicin.

Here, we developed Pluronic® P123/F127 (poloxamer) mixed micelles for the intravenous delivery of the anticancer drug sorafenib (SRB) or its combination with verteporfin (VP), a photosensitizer for photodynamic therapy that should complement well the cytotoxicity profile of the chemotherapeutic. SRB loading inside the core of micelles was governed by the drug:poloxamer weight ratio, while in th...

Some water bodies in the Sinos River Basin (SRB) have been suffering the effects of pollution by residential, industrial and agroindustrial wastewater. The presence of cytotoxic and genotoxic compounds could compromise the water quality and the balance of these ecosystems. In this context, the research aimed to evaluate the genotoxicity and cytotoxicity of the water at four sites along the SRB ...
