This paper describes a liquid-liquid biphasic flow reaction system that is simple to control. In a liquid-liquid biphasic flow reaction, the slug-flow in the tube reactors generally improves the reaction rate. However, we show that larger tube diameters decreased the reaction rate and the formation of the slug-flow was influenced by the tube diameter, the size of the mixer, and the pump mechanism. These results indicated that technical difficulties with the slug-flow could be an obstacle to scale-up. To resolve this problem, we suggest the use of a Taylor vortex flow reactor to achieve a higher reaction rate than with batch and slug-flow systems.

Twenty-four 1,2-diarylbenzimidazole derivatives were designed, synthesized and biologically evaluated. It turned out that most of them were potential anticancer drugs. Among them, compound c24 showed the highest anti-tumor activity (GI(50) = 0.71-2.41 mu M against HeLa, HepG2, A549 and MCF-7 cells), and low toxicity to normal cells (CC50 > 100 mu M against L02 cells). In the microtubule binding assay, c24 showed the most potent inhibition of microtubule polymerization (IC50 = 8.47 mu M). The binding ability of compound c24 to tubulin crystal was verified by molecular docking simulation experiment. Further studies on HepG2 and HeLa cells showed that compound c24 could cause mitotic arrest of tumor cells to G2/M phase then inducing apoptosis. To sum up, compound c24 is a promising microtubule assembly inhibitor.

With the aim of expanding the scope of SAR on piperlongumine (PL), a naturally occurring anticancer molecule, we have designed a novel hybrid molecule bearing 3,4-dihydroisoquinolin-1(2H)-one and trans-cinnamic acids. The structure, based on hybridization strategy, is used for hybridization of naturally occurring scaffolds. We have synthesized 14 hybrid molecules by coupling 3,4-dihydroisoquinolin-1(2H)-one core with cinnamic acids using the mix anhydride approach. The newly synthesized inhibitors were evaluated for cell viability against breast cancer MCF-7 and cervical cancer HeLa cell lines. Furthermore, the active compounds were screened for their potential in breast cancer MDA-MB-231, cervical cancer C33A cell lines, prostate cancer DU-145, PC-3, and normal VERO cells. From the series, compound 10g was seen to inhibit MCF-7 cell growth significantly with GI(50) < 0.1 mu M along with growth inhibition in MDA-MB-231 (GI(50) = 20 mu M) and C33A (GI(50) = 3.2 mu M). While the inhibitor 10i inhibits MCF-7 breast cancer cell growth GI(50) = 3.42 mu M along with inhibition of cell growth in MDA-MB-231 (GI(50) = 30 mu M), HeLa (GI(50) = 7.67 mu M), C33A (GI(50) = 13 mu M), DU-145 (GI(50) = 6.45 mu M), PC-3 (GI(50) = 8.68 mu M), and VERO (GI(50) = 2.93 mu M), respectively. Furthermore, molecular docking study demonstrated these compounds could bind tightly to the colchicine domain of tubulin through a network of favorable steric and electrostatic interactions and thus act as a tubulin polymerization inhibitor.

Naloxone is an opioid antagonist with high affinity for -opioid receptor, and for this reason it is used for the emergency treatment of opioid overdose. Originally, it was available only as an injectable product. However, for the ease of administration, intranasal (IN) formulations have also become available. These IN formulations contain preservatives and stabilizers such as benzalkonium chloride (BKC), benzyl alcohol (BA), and ethylenediaminetetraacetic acid (EDTA). Some of these ingredients are known to affect permeability of drugs. This study focuses on investigating the effect of formulation variables including choice of preservatives, stabilizer, and pH on the permeability and stability of naloxone IN formulations. The in vitro permeability of naloxone was evaluated employing EpiAirway tissue-mounted Ussing chambers. BKC was found to enhance the apparent permeability (P-app) of naloxone significantly (p<0.05) at very low concentration, while BA caused similar enhancement at a much higher concentration. EDTA was found to decrease P-app of naloxone by lowering the pH, and the P-app of naloxone was found to decrease approximately 51-fold with the decrease in formulation pH from 6.0 to 4.0. The product stability was, however, found optimal only below pH 5.0. Thus, selection of formulation ingredients, buffering agent, and pH of IN formulation is a balancing act for achieving desired permeability and optimal stability to achieve reasonable shelf life of naloxone IN formulation.

A nanomagnetic catalyst based on the nano-Fe3O4 core was synthesized and used in the synthesis of the hexahydroquinoline derivatives which acts as a solid heterogeneous catalyst. The as-prepared catalyst was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction, energy dispersive X-ray spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, vibrational sample magnetometry, and thermal gravimetric analysis. Catalyst activity was tested in the synthesis of hexahydroquinoline derivatives. The FTIR shows that the catalyst can activate as the carbonyl group of the benzaldehyde, so that it can motivate the reaction. The proposed method has important features which include solvent free, mild, high yield, shorter reaction time, easy preparation and separation of the catalyst, and efficient workup procedure. On the other hand, the design of experiment was used as a systematic method for the programing of the reaction condition. Optimization showed that the optimal reaction temperature and amount of catalyst were 65 degrees C and 0.05 g, respectively.

Formula: C7H6O2. I found the field of Biochemistry & Molecular Biology; Pharmacology & Pharmacy; Food Science & Technology very interesting. Saw the article Qualitative Chemical Characterization and Multidirectional Biological Investigation of Leaves and Bark Extracts of Anogeissus leiocarpus (DC.) Guill. & Perr. (Combretaceae) published in 2019.0, Reprint Addresses Ferrante, C (corresponding author), Univ G dAnnunzio, Dept Pharm, I-66100 Chieti, Italy.; Zengin, G (corresponding author), Selcuk Univ, Fac Sci, Dept Biol, TR-42130 Konya, Turkey.; Mahomoodally, MF (corresponding author), Univ Mauritius, Fac Sci, Dept Hlth Sci, Reduit 230, Mauritius..

Anogeissus leiocarpus (DC.) Guill. & Perr. (Combretaceae) has a long history of use by folk populations for the management of multiple human ailments. Based on the published literature, there has been no attempt to conduct a comparative assessment of the biological activity and the phytochemical profiles of the leaves and stem bark of A. leiocarpus extracted using methanol, ethyl acetate, and water. By high-performance liquid chromatography with electrospray ionization mass spectrometric detection (HPLC-ESI-MSn) analysis, quinic, shikimic, gallic, and protocatechuic acids were tentatively identified from all the extracts, while chlorogenic, caffeic, ferulic, and dodecanedioic acids were only characterised from the leaves extracts. Additionally, a pharmacological study was carried out to evaluate potential protective effects that are induced by the extracts in rat colon and colon cancer HCT116 cell line. In general, the methanol and water extracts of A. leiocarpus leaves and stem bark showed potent radical scavenging and reducing properties. It was noted that the stem bark extracts were more potent antioxidants as compared to the leaves extracts. The methanol extract of A. leiocarpus leaves showed the highest acetyl (4.68 mg galantamine equivalent/g) and butyryl (4.0 mg galantamine equivalent/g) cholinesterase inhibition. Among ethyl acetate extracts, the pharmacological investigation suggested stem bark ethyl acetate extracts to be the most promising. This extract revealed ability to protect rat colon from lipopolysaccharide-induced oxidative stress, without exerting promoting effects on HCT116 cell line viability and migration. As a conclusion, A. leiocarpus represents a potential source of bioactive compounds in the development of novel therapeutic agents.

Electronic cigarettes (e-cigarettes) have become popular alternatives to traditional tobacco. Despite this, a comprehensive evaluation of their long-term effects and safety for the consumers and the environment is missing. To contribute to filling this gap, headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME/GC-MS) was employed to establish and compare the volatile fingerprints of traditional tobacco and e-cigarettes. The analysis of traditional tobacco included two popular brands and different parts of the cigarette (solid tobacco, cigarette smoke, cigarette paper and filter). Regarding the e-cigarettes, two e-liquids, with and without nicotine, their main constituents (e-bases) and corresponding vapours, obtained under default vaping (power) conditions, were analysed. A total of 80 volatile organic compounds (VOCs) were identified in traditional tobacco, of which 14 carbonyl compounds, 9 benzene derivatives, 9 ethyl esters and 9 hydrocarbons. Slight differences in the volatile profile of cigarette paper and filter between the two brands were also detected, showing that exogenous components of tobacco influence the flavour and harmfulness perceived by the smokers. In turn, 92 VOCs were identified in e-cigarettes, including 31 ethyl esters, 18 alcohols and 10 hydrocarbons. No VOCs with potentially toxic or harmful effects were identified in the vapour of Do It Yourself (DIY) liquids and Premium samples. Therefore, taking into consideration the volatile compositions obtained for smoking and vaping procedures under normal conditions of operation and using certified e-liquid mixtures, the e-cigarettes analysed seemed to constitute a valid and less harmful alternative to traditional tobacco for smokers, secondhand smokers and the environment.

Background Baloxavir marboxil (baloxavir) is a new anti-influenza virus agent that is comparable to oseltamivir phosphate (oseltamivir). Since the efficacy of baloxavir in preventing household transmission of influenza is not well established, we compared the secondary household influenza virus transmission rates between patients on baloxavir vs oseltamivir. Methods Between October 2018 and March 2019, we enrolled index patients (diagnosed with influenza and treated with baloxavir or oseltamivir) and household members. The secondary attack rate of household members was compared between index patients treated with baloxavir vs oseltamivir. Risk factors of household transmission were determined using multivariate logistic analyses. Results In total, 169 index patients with influenza type A were enrolled. The median age was 27.0 (interquartile range; 11-57) years. The number of index patients treated with baloxavir and oseltamivir was 49 and 120, respectively. The secondary attack rate was 9.0% (95% confidence interval [CI]: 4.6-15.6) in the baloxavir group and 13.5% (95% CI: 9.8-17.9) in the oseltamivir group. In the multivariate analysis, independent risk factors were 0-6 years of age (odds ratio [OR] 2.78, 95% CI: 1.33-5.82,p < 0.01) and not being on baloxavir treatment. (OR: 0.63, 95% CI: 0.30-1.32,p = 0.22). Conclusion The household secondary attack rate of influenza was comparable in patients treated with baloxavir vs oseltamivir. Therefore, baloxavir can be used as an alternative therapy to oseltamivir in reducing household transmission of influenza.
