Published: January 2013

The synthesis of new acridinone and dioxophenothiazine derivatives along with their tubulin polymerization inhibitory and antiproliferative activities is reported. The analysis of correlation for cytotoxic and antitubulin potential of tested compounds showed that 4-methoxyphenylethyl derivatives 18a and 19a were highly cytotoxic but were regarded to have no significant antitubulin activity. However, the introduction of a 3-hydroxy substituent leading to compounds 18e and 19e, strongly increased the antitubulin potential but was associated with a loss of the antiproliferative activity. Modeling studies, topoisomerase inhibition assays and cell cycle analysis have been performed to better investigate the mechanism of action of such compounds.

Plants constitute a source of natural phytochemical components which are widely known for their potential biological activities. This work concerned a study of the antioxidant, anticancer and anti-inflammatory activities of squirting cucumber (Ecballium elaterium L.) parts (flowers, fruits, leaves and stems) using different solvent extracts (cyclohexane, dichloromethane, ethyl acetate, methanol and water).

This study evaluated the antioxidant and antiproliferative effects of aqueous, ethanolic and methanolic extracts of Sedum nicaeense flowers and leaves. The MTT assay assessed cytotoxicity against colorectal cancer cells (Caco-2, HCT-116), breast cancer cells (T47D, MCF-7) and normal fibroblasts (MRC-5), while the ferric-reducing antioxidant power (FRAP) assay measured antioxidant capacity. Essential oils from flowers and leaves were analyzed using gas chromatography-mass spectrometry (GC-MS).

Novel pH-sensitive polymeric photosensitizer carriers from the phthalocyanine (Pc) group were investigated as potential photodynamic therapy drugs for the treatment of breast cancer. Their high antiproliferative activity was confirmed by photocytotoxicity studies, which indicated their high efficacy and specificity toward the SK-BR-3 cell line. Importantly, the Pcs encapsulated in the polymeric nanoparticle (NP) carrier exhibited a much better penetration into the acidic environment of tumor cells than their free form.

The discovery of novel anti-cancer drugs motivated us to synthesize a new series of triple 1,2,3-triazole-based arm scaffolds featuring distinct un functionalized alkyl and/or aryl side chains with possible anti-cancer action using the click chemistry approach under both conventional and green microwave irradiation (MWI) methods. The Cu(I) catalyzed cycloaddition reaction of targeted tris-alkyne with un functionalized aliphatic and aromatic azides has been adopted as an efficient approach for synthesizing the desired click adducts. Microwave irradiation improved the synthetic processes, resulting in higher yields and faster reaction times.

Pleurotin (1) is a benzoquinone meroterpenoid known for its wide-spectrum antitumor and antibiotic activities, notably acting as natural inhibitors of the thioredoxin reductase (TrxR). Pleurotin (1) has been chemically synthesized, but only in milligram quantities through at least 13 longest linear steps with 0.8 % overall yield due to its complex structure such as fused hexacyclic core with 8 contiguous stereocenters.
