Smirnova, Irina published the artcileHollongdione arylidene derivatives induce antiproliferative activity against melanoma and breast cancer through pro-apoptotic and antiangiogenic mechanisms, Application of 2,3-Dimethoxybenzaldehyde, the main research area is melanoma breast cancer hollongdione arylidene derivative antiangiogensis; Antiproliferative activity; Arylidene; CAM assay; Claisen-Schmidt aldol condensation; Cytotoxicity; Dammarane triterpenoids; Dipterocarpol; Hollongdione; NCI-60; rtPCR.

The use of natural compounds as starting point for semisynthetic derivatives has already been proven as a valuable source of active anticancer agents. Hollongdione (4,4,8,14-tetramethyl-18-norpregnan-3,20-dion), obtained by few steps from dammarane type triterpenoid dipterocarpol, was chem. modified at C2 and C21 carbon atoms by the Claisen-Schmidt aldol condensation to give a series of arylidene derivatives The anticancer activity of the obtained compounds was assessed on NCI-60 cancer cell panel, revealing strong antiproliferative effects against a large variety of cancer cells. 2,21-Bis-[3-pyridinyl]-methylidenohollongdione 9 emerged as the most active derivative as indicated by its GI50 values in the micromolar range which, combined with its high selectivity index values, indicated its suitability for deeper biol. investigation. The mechanisms involved in compound 9 antiproliferative activity, were investigated through in vitro (DAPI staining) and ex vivo (CAM assay) tests, which exhibited its apoptotic and antiangiogenic activities. In addition, compound 9 showed an overall inhibition of mitochondrial respiration. rtPCR anal. identified the more intimate activity at pro-survival/pro-apoptotic gene level. Collectively, the hollongdione derivative stand as a promising therapeutic option against melanoma and breast cancer provided that future in vivo anal. will certify its clin. efficacy.

Popova, Svetlana A. published the artcileIsobornylchalcones as scaffold for the synthesis of diarylpyrazolines with antioxidant activity, Related Products of isoquinoline, the main research area is diarylpyrazoline isobornylchalcone scaffold antioxidant activity; Fe2+/ascorbate-initiated lipid peroxidation; antioxidant activity; diarylpyrazolines; isobornylchalcones.

The pyrazoline ring is defined as a “”privileged structure”” in medicinal chem. A variety of pharmacol. properties of pyrazolines is associated with the nature and position of various substituents, which is especially evident in diarylpyrazolines. Compounds with a chalcone fragment show a wide range of biol. properties as well as high reactivity which is primarily due to the presence of an α, β-unsaturated carbonyl system. At the same time, bicyclic monoterpenoids deserve special attention as a source of a key structural block or as one of the pharmacophore components of biol. active mols. A series of new diarylpyrazoline derivatives based on isobornylchalcones with different substitutes (MeO, Hal, NO2, N(Me)2) was synthesized. Antioxidant properties of the obtained compounds were comparatively evaluated using in vitro model Fe2+/ascorbate-initiated lipid peroxidation in the substrate containing brain lipids of laboratory mice. It was demonstrated that the combination of the electron-donating group in the para-position of ring B and OH-group in the ring A in the structure of chalcone fragment provides significant antioxidant activity of synthesized diarylpyrazoline derivatives

Li, Ge published the artcileDesign and Green Synthesis of Piperlongumine Analogs and Their Antioxidant Activity against Cerebral Ischemia-Reperfusion Injury, Formula: C9H10O3, the main research area is piperlongumine analog green synthesis antioxidant cerebral ischemia reperfusion injury; structure activity piperlongumine analog cerebral ischemia reperfusion injury; Michael acceptor; Piperlongumine analogs; antioxidation; cerebral ischemia-reperfusion injury; green synthesis; neuroprotection; stroke.

The supplementation of exogenous antioxidants to scavenge excessive reactive oxygen species (ROS) is an effective treatment for cerebral ischemia reperfusion injury (CIRI). Piperlongumine (PL) is a kind of natural product which has great potential as a neuroprotective agent, but it also has obvious neurotoxicity. Moreover, its neuroprotective effects remain to be improved. In this study, a series of novel PL analogs were designed on the foundation of the screened low-toxic diketene skeleton with antioxidation and the 3,4,5-trimethoxyphenyl group, which might increase the antioxidant activity of PL. The cytotoxicity and activity tests on a series of PL analogs I [R1 = 3,4,5-(MeO)3C6H2, R2 = 2,4-Cl2C6H3, 2-HOC6H4, piperidin-1-yl, etc.; R1 = H, R2 = 3,4,5-(MeO)3C6H2], which were synthesized by a novel green synthesis method, indicated that all of these compounds without obvious toxicity have remarkable antioxidant effects, especially compared with diketene skeletons and PL. The cytoprotection of the active compound also decreased significantly when the carbon-carbon double bonds of the mol. skeleton were reduced. More importantly, further study revealed that compound I [R1 = 3,4,5-(MeO)3C6H2, R2 = 2,4,6-(MeO)3C6H2], which has the best activity, can confer protection for cells against oxidative stress and attenuate brain injury in rats. Overall, our findings provide a promising drug candidate for the treatment of CIRI and guide the further development of drug research in oxidative stress-mediated diseases.

Subagyono, Rr dirgarini j. n. published the artcilePyrolysis of fast growing wood Macaranga gigantea: Product characterisation and kinetic study, SDS of cas: 86-51-1, the main research area is growing wood macaranga gigantea pyrolysis activation energy.

Fast-growing wood Macaranga gigantea has been pyrolyzed and its pyrolysis products have been characterized and their formation kinetics studied. Pyrolysis of M. gigantea wood was carried out by varying the temperature and time of pyrolysis to determine the effect of these two parameters on product yields and product characteristics. In general, an increase in pyrolysis temperature and time increased the yield of liquid and gas products, the concentration of cellulose, hemicellulose and lignin-derived compounds, but decreased the biochar yield. The organic phase liquid pyrolysis products mainly contained phenolic compounds and their derivatives, eugenols, furans, aldehydes and ketones. Fourier-transform IR spectroscopy and pyrolysis-gas chromatog.-mass spectrometry analyses of biochar showed that thermal decomposition of M. gigantea required temperatures higher than 300°C to optimize thermal decomposition and carbonization of lignin, cellulose and hemicellulose. The concentration of phenols and benzenediols in biochar decreased with an increase in pyrolysis temperature M. gigantea pyrolysis kinetics studies showed that wood pyrolysis occurred through four main stages with activation energy (Eα) values, based on calculations by the Friedman and Kissinger-Akahira-Sunose methods, of 28.1-99.0 kJ/mol and 35.6-104.9 kJ/mol, resp. The spectra produced by thermogravimetric analyzer coupled with a Fourier-transform IR spectroscopy showed that H2O and CO2 were produced during pyrolysis and the volatile compounds produced were predominantly phenolic compounds, in accord with characterization results of the liquid products by gas chromatog.-mass spectrometry and NMR spectroscopy.
