Cannabis sativa is one of the oldest medicinal plants used by humans, containing hundreds of bioactive compounds. The biological effects and interplay of these compounds are far from fully understood, although the plant’s therapeutic effects are beyond doubt. Extraction methods for these compounds are becoming an integral part of modern Cannabis-based medicine. Still, little is known about how different methods affect the final composition of Cannabis extracts and thus, their therapeutic effects. In this study, different extraction methods were tested, namely maceration, Soxhlet, ultrasound-assisted extraction (UAE), and supercritical CO2 extraction methods. The obtained extracts were evaluated for their cannabinoid content, antioxidant properties, and in vitro bioactivity on human colon cancer and healthy colon cells. Our data suggest that Cannabis extracts, when properly prepared, can significantly decrease cancer cell viability while protecting healthy cells from cytotoxic effects. However, post-processing of extracts poses a significant limitation in predicting therapeutic response based on the composition of the crude extract, as it affects not only the actual amounts of the respective cannabinoids but also their relative ratio to the primary extracts. These effects must be carefully considered in the future preparations of new therapeutic extracts.

Gut Fermentation

Intake of fibre has beneficial properties on gut health. Butyrate, a product of bacterial gut fermentation, is thought to contribute to positive effects by retarding growth and enhancing apoptosis of tumour cells. One mechanism is seen in its capacity to modulate histone acetylation and thereby transcriptional activity of genes. Next to butyrate, propionate and acetate are also major products of gut fermentation and together they may exert different potencies of cellular effects than butyrate alone. Since virtually nothing is known on combination effects by SCFA mixtures, here we had the aim to assess how physiological relevant concentrations and mixtures of SCFA modulate histone acetylation in human colon cells. HT29 colon cancer cells were incubated with mixtures of butyrate, acetate and propionate and with the individual compounds as controls. Histone acetylation was determined with acid-urea gel electrophoresis and immunoblotting. Acetylated histones slowly increased over 24 h and persisted up to 72 h in butyrate-treated HT29 cells. Butyrate (5–40 mm) and propionate (20–40 mm) enhanced histone acetylation significantly after 24 h incubation, whereas acetate (2·5–80 mm) was ineffective. Mixtures of these SCFA also modulated histone acetylation, mainly due to additive effects of butyrate and propionate, but not due to acetate. In conclusion, physiological concentrations of propionate together with butyrate could have more profound biological activities than generally assumed. Together, these SCFA could possibly mediate important processes related to an altered transcriptional gene activation and thus contribute to biological effects possibly related to cancer progression or prevention.

Background: Many pyrazole piperazine derivatives are known to exhibit a wide range, thus being attractive for the drug design and synthesis of interesting class of widely studied heterocyclic compounds. It is therefore necessary to devote continuing effort for the identification and development of New Chemical Entities (NCEs) as potential antibacterial and anticancer agents to address serious health problems. Methods: A series of new compounds containing pyrazole ring linked to a piperazine hydrochloride moiety were synthesized and screened for their antibacterial activity, cytotoxicity of novel scaffolds are described by variation in therapeutic effects of parent molecule. The structure variants were characterized by using a blend of spectroscopic 1H NMR, 13C NMR, IR, Mass and chromatographic techniques. Results: When tested for in vitro antibacterial and anticancer activities, several of these compounds showed good activities. The target compounds 9b, 9a and 9e exhibited a high degree of anticancer activity against human colon cancer cell line Caco-2 and human breast cancer cell line MDAMB231. Further, 9a, 9b, 9d, and 9h showed better activity towards four medically relevant organisms; Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Klebsiella Species compared to CPF. In the present investigation, cheminfomatics tools Molinspiration, 2003 and MolSoft, 2007 for the prediction of insilico molecular properties and drug likeness for the target compounds 9a-h was evaluated and positive results were observed. Conclusion: Our study revealed that the molecular framework presented here could be a useful template for the identification of novel small molecules as promising antibacterial/ anticancer agents.

Pterostilbene is a dietary phytochemical that has been found to possess several biological activities, such as antioxidant and anti-inflammatory. Recent studies have shown that it exhibits the hallmark characteristics of an anticancer agent. The aim of the study was to investigate the anticancer activity of pterostilbene against HT-29 human colon cancer cells, focusing on its influence on cell growth, differentiation, and the ability of this stilbene to induce cell death. To clarify the mechanism of pterostilbene activity against colon cancer cells, changes in the expression of several genes and proteins that are directly related to cell proliferation, signal transduction pathways, apoptosis, and autophagy were also evaluated. Cell growth and proliferation of cells exposed to pterostilbene (5–100 µM) were determined by SRB and BRDU assays. Flow cytometric analyses were used for cell cycle progression. Further molecular investigations were performed using quantitative real-time RT-PCR. The expression of the signaling proteins studied was determined by the ELISA method. The results revealed that pterostilbene inhibited proliferation and induced the death of HT-29 colon cancer cells. Pterostilbene, depending on concentration, caused inhibition of proliferation, G1 cell arrest, and/or triggered apoptosis in HT-29 cells. These effects were mediated by the down-regulation of the STAT3 and AKT kinase pathways. It may be concluded that pterostilbene could be considered as a potential therapeutic option in the treatment of colon cancer in the future.
