A Nanomechanical Study on Deciphering the Stickiness of SARS-CoV-2 on Inanimate Surfaces

The SARS-CoV-2 virus that causes the COVID-19 epidemic can be transmitted via respiratory droplet-contaminated surfaces or fomites, which urgently requires a fundamental understanding of intermolecular interactions of the coronavirus with various surfaces. The corona-like component of the outer surface of the SARS-CoV-2 virion, named spike protein, is a key target for the adsorption and persistence of SARS-CoV-2 on various surfaces. However, a lack of knowledge in intermolecular interactions between spike protein and different substrate surfaces has resulted in ineffective preventive measures and inaccurate information. Herein, we quantified the surface interaction and adhesion energy of SARS-CoV-2 spike protein with a series of inanimate surfaces via atomic force microscopy under a simulated respiratory droplet environment. Among four target surfaces, polystyrene was found to exhibit the strongest adhesion, followed by stainless steel (SS), gold, and glass. The environmental factors (e.g., pH and temperature) played a role in mediating the spike protein binding. According to systematic quantification on a series of inanimate surfaces, the adhesion energy of spike protein was found to be (i) 0-1 mJ/m(2) for hydrophilic inorganics (e.g., silica and glass) due to the lack of hydrogen bonding, (ii) 2-9 mJ/m(2) for metals (e.g., alumina, SS, and copper) due to the variation of their binding capacity, and (iii) 6-11 mJ/m(2) for hydrophobic polymers (e.g., medical masks, safety glass, and nitrile gloves) due to stronger hydrophobic interactions. The quantitative analysis of the nanomechanics of spike proteins will enable a protein-surface model database for SARS-CoV-2 to help generate effective preventive strategies to tackle the epidemic.

Inhibitory effect of 3,4-diaryl-3-pyrrolin-2-one derivatives on cyclooxygenase 1 and 2 in murine peritoneal macrophages

AIM: To develop a whole-cell assay based on murine peritoneal macrophages and evaluate the inhibitory effect of candidate compounds on cyclooxygenase-1 (COX-1) and COX-2. METHODS: Macrophages were stimulated with calcimycin or hpopolysaccharide (LPS) for various periods. Their abilities to convert endogenous arachidonic acid to 6-keto-PGF(1alpha) or PGE(2) were examined by radioimmunoassay (RIA). RNA level of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and COX-1/2 was detected by reverse transcription polymerase chain reaction (RT-PCR) using specific primers. RESULTS: Rofecoxib selectively inhibited LPS-induced, COX-2-derived PGE(2) synthesis with an IC50 value of (4.7+/-0.5) nmol/L compared with maximum inhibitory ratio of 17.3 % for the inhibition of calcimycin induced, COX-1-derived 6-keto-PGF(1alpha) synthesis. Indomethacin exhibited dual inhibitory effects on COX-1 and COX-2 with IC50 of (4.7+/-1.1) nmol/L and (7.1+/-1.2) nmol/L, respectively. Two series of 17 compounds were tested. Most of compounds in series 11 showed comparable inhibitory activities to rofecoxib on COX-2. The relative position of the sulfonylphenyl group to the lactam carbonyl group has important effects on COX-2 inhibitory activity. CONCLUSION: The established whole cell assay is appropriate for drug-design oriented in vitro assay. 3,4-Diaryl-3-pyrrolin-2-one derivatives were proved to be prospective new type of COX-2 selective inhibitors.

Acceptorless dehydrogenative coupling with Ru-based catalysts for the synthesis of N-heteroaromatic compounds

Ru-Catalyzed acceptorless dehydrogenative coupling (ADC) and auto-transfer-hydrogenative (ATH) reactions are effective, versatile transformations for the constructions of N-heteroaromatic compounds from alcohols. Water and hydrogen are the by-products and the starting alcohols are less toxic, more readily available and more easily handled than their halogenated counterparts. A variety of homogeneous ruthenium catalysts, alcohols and partner-substrates such as amines, ammonia, amidines and nitriles, have been used to build N-heteroaromatic compounds in one-pot, multi-step syntheses. This review details recently reported Ru catalysts employed for these reactions, describing the scope of each methodology, proposed reaction mechanisms, regioselectivity of coupling and applications in synthesis.

The study of genotoxicity of two newly synthesized pyrrolinone derivatives on L5178Y mouse lymphoma and bone marrow cells

Genotoxic activity of two newly synthesized pyrrolinone derivatives (lactone (PTB) and lactame (PTP)) was studied both in vitro and in vivo. The substances were incubated with L5178Y mouse lymphoma cells for 4 h, then washed from the substances, and incubated for 18 h. PTP induced significantly increased number of micronuclei (MN) only at the highest dose used (1000 mug/ml). The 20-fold increase of the concentration of PTP led to 2.4-fold increase of the number of MN. PTP wasn’t toxic for lymphoma cells in the applied concentration range. In contrast, PTB induced significantly increased number of MN in lymphoma cells beginning from the concentration of 50 mug/ml and was toxic for lymphoma cells at concentrations of 500 mug/ml and higher. In the comet assay with L5178Y mouse lymphoma cells both substances were active at all concentrations used (PTP at concentrations of 50 mug/ml and 100 mug/ml, and PTB at concentrations of 100 mug/ml and 250 mug/ml). Acute toxicity and MN-inducing activity of compounds were studied on Swiss albino mice. PTB was substantially more toxic for mice than PTP (LD50 was 200 mg/kg and 370 mg/kg respectively). In mouse bone marrow polychromatic erythrocytes PTP induced significantly increased number of MN only at a dose equal to 1/2 of LD50. In contrast, PTB was mutagenic at all doses used -1/2, 1/5, and 1/10 of LD50. At equitoxic doses PTB induced more than 2-fold and 3.5-fold increased levels of MN compared with PTP (1/2 and 1/5 of LD50 respectively). The replacement of =NH group to =O group in chemical structure of pyrrolinone derivatives leads to substantial increase in acute toxicity for mice (1.85-fold) and MN induction activity both in vivo and in vitro.

Inactivation of Thioglucosidase from Sinapis alba (White Mustard) Seed by Metal Salts

The glucosinolates which are specialized plant metabolites of Brassica vegetables are prone to hydrolysis catalyzed by an endogenous enzyme myrosinase (thioglycoside hydrolase, thioglucosidase) that exists in Brassica plant tissue causing volatile isothiocyanates release. Currently existing literature data on the inactivation of myrosinase is insufficient in particular for use in the analysis of volatile and odor compounds in vegetables rich in glucosinolates. In this study, the impact of different metal salts in effective inactivation of enzyme activity was investigated by solid-phase microextraction (SPME) and GC/MS system in aqueous samples and kohlrabi matrix. A saturated solution of calcium chloride which is commonly used to stop enzyme activity in plant tissue inactivates the myrosinase-glucosinolate system. However, even without the participation of myrosinase, it changes the reaction pathway towards nitrile formation. The model experiment shows that optimum efficiency in inhibition of the enzyme system shows iron(III) ions, silver ions, and anhydride sodium sulfate resulting in no volatile products derived from glucosinolates. However, in the kohlrabi matrix, the strongest enzyme inhibition effect was observed for silver salt resulting in no volatile products, also both anhydrous Na2SO4 and saturated CaCl2 solution seem to be useful inhibitors in flavor studies.

Preparation and physical properties of intrinsic low-k polyarylene ether nitrile with enhanced thermo-stability

Polyarylene ether nitrile (PEN) random copolymers were prepared from 6AF, BHPF, and 2, 6-dichlorobenzonitrile according to the nucleophilic aromatic substitution polymerization. The chemical structure of PEN random copolymers was characterized by the FT-IR and H-1-NMR spectrum, respectively. The thermal properties of the PEN random copolymers were investigated by using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The resulting PEN copolymers have excellent thermal stability with high glass transition temperature (T-g) ranging from 187? to 271? and the 5% weight loss temperature (T-5%) of PEN copolymers greater than 490? in nitrogen atmospheres. Meanwhile, the PEN films have excellent mechanical property, the tensile strength ranges from 55 to 95 MPa. Moreover, the dielectric properties of the PEN random copolymers were investigated by dielectric tests. The dielectric constants (k) and loss tangent (tan delta) of PEN (PEN-6-AF/BHPF100) film is only 2.3 and 0.03 at 1 kHz, respectively. More importantly, the dielectric properties were found to be relatively stable until the T-g, which can be attributed to the existence of BHPF units in the molecular backbone.
