: Chalcones are an interesting class of compounds endowed with a plethora of biological activities beneficial to human health. These chemo types have continued to attract increased research attention over the years; hence, numerous natural and synthetic chalcones have found with interesting anticancer activities through the inhibition of various molecular targets including ABCG2, BCRP, P-glycoprotein, 5α-reductase, Androgen receptor (AR), Histone deacetylases (HDAC), Sirtuin 1, proteasome, Vascular endothelial growth factor (VEGF), Cathepsin-K, tubulin, CDC25B phosphatase, Topoisomerase, EBV, NF-κB, mTOR, BRAF and Wnt/β-catenin. Moreover, the study of intrinsic mechanisms of action, particularly relating to specific cellular pathways and modes of engagement with molecular targets, may help medicinal chemists to develop a more effective, selective, and cost-effective chalcone-based anticancer drugs. This review, therefore, sheds light on the effect of structural variations on the anticancer potency of chalcone hybrids reported in 2018-2019 alongside their mechanism of action, molecular targets, and potential impacts on effective cancer chemotherapy.

Ramalin, a new L-glutamic acid derivative of phenylhydrazide (Y-glutamyl-N'-(2-hydroxyphenyl) hydrazide, 1) was isolated from the Antarctic lichen, Ramalina terebrata after a series of bioactivity guided fractionation of crude aqueous methanolic extract. Ramalin showed stronger antioxidant activities than commercially available standards, ascorbic acid, trolox, BHA, kojic acid in both, in vitro and in vivo test systems. In addition, ramalin showed no/less toxicity effects against two human cell lines; fibroblast (CCD-986SK) cells and keratinocyte (HaCaT). Thus, realign merits for cosmetic application and industrial scale production were needed. We developed a cost effective total synthesis of ramalin with 71.5% yield and described here.

Slope Instabilities

<p>Rupestrian Cultural Heritage (CH) sites were among the first man-made works in the history of humanity, therefore playing a key role in building the memory and roots of human society. These sites were often carved in slopes formed by soft rocks, which due to their peculiar lithological, geotechnical and morpho-structural features are often prone to weathering, deterioration and slope instability issues. The use of advanced remote sensing (RS) techniques combined with traditional methods (e.g. field surveys, laboratory analysis), can provide fundamental data to implement a specific site-specific and inter-disciplinary approach for the sustainable protection and conservation of rupestrian CH sites. In this context Infrared Thermography (IRT), thanks to the technological development of portable high-resolution and cost-effective thermal imaging cameras, can be profitably used for the detection of CH conservation issues (namely fractures, water seepage, moisture and surface weathering). In this paper several applications of IRT in integrated methodologies for rupestrian sites conservation in mountainous regions of Georgia will be presented. The aim of this work is to evaluate the potential of IRT in the field of CH protection and conservation strategies, in order to provide a useful versatile and low-cost tool, to be profitably used in management plans of rupestrian CH characterized by similar contexts. Advantages and constraints of the adopted method will be discussed, as well as general operative recommendations and future perspectives.</p>

The search for lead product with beneficial pharmacological properties has become a great challenge and costly. Extraction and synthetic modification of bioactive compounds from natural resources has gained great attention and is cost effective. In this study, kojic acid was produced from fungal fermentation, using sago waste as substrate, and chemically incorporated with chalcones and azobenzene to form a series of kojic ester derivatives and evaluated for antibacterial activities. Kojic ester bearing halogenated chalcone demonstrated active inhibition against Staphylococcus aureus compared to that of standard ampicillin. The inhibition increased as the electronegativity of halogens decreased, while incorporation of azobenzene derivatives on kojic acid backbone demonstrated fair antibacterial activity against Escherichia coli with minimum inhibitory concentration (MIC) of 190–330 ppm. The presence of C=C and N=N reactive moieties in both chalcone and azo molecules contributed to the potential biological activities of the kojic acid ester.

Technological development makes it possible to simplify and accelerate decision-making processes by adequately processing and evaluating large volumes of data. Sub-data obtained from large data sets have a very important practical role in asset valuation, forecasting and valuing delineated or difficult-to-map areas, or in the context of portfolio management. Land valuation is a separate segment within asset valuation and it requires a specific methodological approach on behalf of evaluators. In this study, the authors compared the transaction data of arable land and the value of other land use categories. Based on empirical assessments, the authors developed proposals for the fast and cost-effective determination of the value of land use categories other than arable land - mainly meadows and pastures.

There is a great interest in the development of green protocols to avoid environmental and health hazards. In this research, the eco-friendly and cost-effective synthesis of gold nanoparticles (GNPs) has been achieved by the green method using ethanolic turmeric crude extract at pH 7. The bioac-tive compounds of turmeric crude extract are responsible for the reduction, capping and sta-bility of the GNPs. The characterization of GNPs was carried out by ultraviolet-visible (UV-vis) spectroscopy, Fourier transforms infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM) and energy dispersive X-ray (EDX) spectroscopy. The UV-vis spectral study indicated the formation of GNPs with a surface plasmon resonance (SPR) band at 547 nm. FTIR analysis of turmeric crude extract and GNPs showed that phenolic groups reduced the gold ions. The FESEM analysis showed the polydisperse morphology of GNPs with average size of 26.6 nm±7.4 nm. The elemental composition determined by EDX re-vealed the presence of gold. The synthesized GNPs can be useful in a variety of applications involving medicine, cosmetics, environment and nutraceutical.
