Hydroxy- and alkoxycarbonylation reactions constitute important industrial processes in homogeneous catalysis. Nowadays, palladium complexes constitute state-of-the-art catalysts for these transformations. Herein, we report the first efficient platinum-catalysed alkoxycarbonylations of olefins including sterically hindered and functionalized ones. This atom-efficient catalytic transformation provides straightforward access to a variety of valuable esters in good to excellent yields and often with high selectivities. In kinetic experiments the activities of Pd- and Pt-based catalysts were compared. Even at low catalyst loading, Pt shows high catalytic activity.

I found the field of Biotechnology & Applied Microbiology; Engineering; Food Science & Technology very interesting. Saw the article Improved yield and antioxidant activity of essential oil from Alpinia zerumbet (Zingiberaceae) leaves by underwater shockwave pretreatment published in 2021.0. Application In Synthesis of Methyl 3-phenyl-2-propenoate, Reprint Addresses Kuraya, E (corresponding author), Okinawa Coll, Natl Inst Technol, Sci & Technol Div, 905 Henoko, Nago, Okinawa 9052192, Japan..

The aromatic perennial plant Alpinia zerumbet (Pers.) Burtt & Smith (Zingiberaceae) is widely distributed in the tropical and sub-tropical regions of Japan, from southern Kyushu to the Ryukyu Islands. Its essential oil has a distinct aroma and antioxidant activity but is expensive due to low extraction efficiencies. Applying underwater shockwave pretreatment to A. zerumbet leaves is expected to enable more effective essential oil extraction during subsequent steam distillation. Thus, we subjected A. zerumbet leaves to shockwave pretreatment and analyzed its effects on the essential oil yield and components. Multiple cracks formed in the cell walls via spalling destruction induced by the shockwaves, creating permeation pathways that improved the passage of water vapor and greatly increased the essential oil yield. Moreover, the pretreatment increased the antioxidant activity of the essential oil and its water extract. Underwater shockwave processing selectively and effectively destroyed the fiber and/or cell structures of the leaves, resulting in efficient essential oil extraction. This novel process has the potential for application to many extraction processes, such as the extraction of compounds from medicinal plants. The dynamic control of instantaneous high pressures based on underwater shockwaves could pave the way for a new field of industrial technology. (C) 2020 Institution of Chemical Engineers.

Background Several studies have reported the association between polymorphisms in Matrix metalloproteinases (MMPs) gene family and risk of Multiple sclerosis (MS). However, the results have been inconsistent and inconclusive. To resolve this issue, here we performed a systematic review and meta-analysis of the MMP-91562 C/T (rs3918242), MMP-3 (- 1612 5A/6A), and MMP-2 (- 1306 C/T) polymorphisms and susceptibility to MS. Methods We conducted a comprehensive systematic search in the major electronic database, including Scopus and PubMed to look up for relevant studies published before December 2019 that surveyed the association between the MMP-91562 C/T (rs3918242), MMP-3 (- 1612 5A/6A), and MMP-2 (- 1306 C/T) polymorphisms and susceptibility to MS. The level of association between the polymorphisms and susceptibility to MS in the polled analysis was determined by calculating the odds ratio (OR) and the corresponding 95% confidence interval (CI). Results We found 15 studies containing 2430 MS subjects and 2304 controls. A statistically significant association was observed in the all five comparisons of the MMP-91562 C/T polymorphism and MS risk as follows: dominant model (OR = 1.62, 95% CI = 1.03-2.53, P = 0.03), recessive model (OR = 2.69, 95% CI = 1.68-4.29, P < 0.001), allelic model (OR = 1.51, 95% CI = 1-2.28, P = 0.04), TT vs. CC model (OR = 3.20, 95% CI = 1.87-5.46, P < 0.001), and CT vs. CC model (OR = 1.53, 95% CI = 1.02-2.28, P = 0.04). Conclusions Our meta-analysis revealed significant association of MMP-9 (- 1562 C/T) Single-nucleotide polymorphism (SNP) with MS susceptibility that increased the disease risk. SDS of cas: 103-25-3.

A key event in the directed evolution of enzymes is the systematic use of mutagenesis and selection, a process that can give rise to mutant libraries containing millions of protein variants. To this day, the functional analysis and identification of active variants among such high numbers of mutational possibilities is not a trivial task. Here, we describe a combinatorial semi-rational approach to partly overcome this challenge and help design smaller and smarter mutant libraries. By adapting a liquid medium transesterification assay in organic solvent conditions with a combination of virtual docking, iterative saturation mutagenesis, and residue interaction network (RIN) analysis, we engineered lipase B from P. antarctica (CalB) to improve enzyme recognition and activity against the bulky aromatic substrates and flavoring agents methyl cinnamate and methyl salicylate. Substrate-imprinted docking was used to target active-site positions involved in enzyme-substrate and enzyme-product complexes, in addition to identifying ‘hot spots’ most likely to yield active variants. This iterative semi-rational design strategy allowed selection of CalB variants exhibiting increased activity in just two rounds of site-saturation mutagenesis. Beneficial replacements were observed by screening only 0.308% of the theoretical library size, illustrating how semi-rational approaches with targeted diversity can quickly facilitate the discovery of improved activity variants relevant to a number of biotechnological applications.

The purpose of this study was to inspect the suitability of sweet basil (Ocimum basilicumL.) for phytoremediation of heavy metal contaminated areas in urban areas of Egypt through study the impact of the most common pollutants in Egypt: cadmium (Cd) and lead (Pb) on morphological traits, and essential oil (EOs) content of sweet basil. The experiment was done under greenhouse conditions. The applied treatments tested in this experiment for Cd concentrations were 5, 10, 15, 20, 25 ppm and for Pb: 100, 350, 750, 1,000, 1,500 ppm. The composition and amount of EOs had been determined using gas chromatography-mass spectrometry (GC-MS). The results indicated that the contaminated soil had a negative impact on morphological traits development of basil (e.g., the decline in fresh and dry weight). The increase in Cd and Pb concentrations enhanced the EOs yield of sweet basil. In general, basil cultivation in the Cd and Pb contaminated soils could cause undesirable impacts on morphological traits; however, the presence of these metals has a major influence on the EOs yield, composition, and phytoremediation of the soil.

Treatment of 2-arylbenzoic acids with N-chlorosuccinimide (NCS) and NaI at 70 degrees C under fluorescent lighting condition gave the corresponding 3,4-benzocoumarins in good yields under transition-metal-free condition. It was found that the reactivity of NCS with NaI for the formation of 3,4-benzocoumarins from 2-arylbenzoic acids was as high as that with NIS. Thus, the formation of carboxyl radicals and their cyclization onto an aromatic ring from 2-arylbenzoic acids with much less expensive NCS and NaI, than NIS could be successfully carried out to form 3,4-benzocoumarins.

This report describes the synthesis of five new colorful 6-aryldibenzo[b,d]pyrylium cation salts, a largely unexplored structural unit. These rare compounds are benzannulated structural derivatives of the well-known flavylium cations found widespread in natural pigments. These new dyes are directly compared to three previously synthesized 6-aryldibenzo[b,d]pyrylium cation salts as well as eight colorful isomeric 9-aryldibenzo[b,d]pyrylium cation, or 9-arylxanthylium, salts. The 9-arylxanthylium unit is commonly found in the biologically important rhodamine and rosamine dyes, yet six of the analogs presented in this study were either previously unreported or not isolated. The visual and spectroscopic properties of all 16 compounds were analyzed as a function of the structural differences between the compounds. All compounds displayed reversible halochromism in organic solution, displaying bright colors under acidic conditions and becoming colorless under basic conditions. (C) 2020 Elsevier Ltd.
