The rate of mutability of pathogenic H1N1 influenza virus is a threat. The emergence of drug resistance to the current competitive inhibitors of neuraminidase, such as oseltamivir and zanamivir, attributes to a need for an alternative approach. The design and synthesis of new analogues with alternate approach are particularly important to identify the potential neuraminidase inhibitors which may not only have better anti-influenza activity but also can withstand challenge of resistance. Five series of scaffolds, namely aurones (1a-1e), pyrimidine analogues (2a-2b), cinnamic acid analogues (3a-3k), chalcones (4a-4h) and cinnamic acid linkages (5a-5c), were designed based on virtual screening against pandemic H1N1 virus. Molecular modelling studies revealed that the designed analogues occupied 430-loop cavity of neuraminidase. Docking of sialic acid in the active site preoccupied with the docked analogues, i.e. in 430-loop cavity, resulted in displacement of sialic acid from its native pose in the catalytic cavity. The favourable analogues were synthesized and evaluated for the cytotoxicity and cytopathic effect inhibition by pandemic H1N1 virus. All the designed analogues resulting in displacement of sialic acid suggested alternate binding mechanism. Overall results indicated that aurones can be measured best among all as potential neuraminidase inhibitor against pandemic H1N1 virus. [GRAPHICS] .

The one-pot three-component reaction of p-quinone monoacetals (or p-quinol ethers), l-proline and naphthols is developed for the synthesis of N-aryl-2-arylpyrrolidines under mild conditions with high chemo- and regioselectivity. The reaction may involve multiple processes including condensation, decarboxylation and demethoxylation for the the generation of N-arylated 3,4-dihydro-2H-pyrrolium followed by controllable capture by naphthols. In the absence of a naphthol, p-quinone monoacetal coupled with l-proline to form a complex dipyrroloquinoline product.

Arylation of carbonyls, one of the most common approaches toward alcohols, has received tremendous attention, as alcohols are important feedstocks and building blocks in organic synthesis. Despite great progress, there is still a great gap to develop an ideal arylation method featuring mild conditions, good functional group tolerance, and readily available starting materials. We now show that electrochemical arylation can fill the gap. By taking advantage of synthetic electrochemistry, commercially available aldehydes (ketones) and benzylic alcohols can be readily arylated to provide a general and scalable access to structurally diverse alcohols (97 examples, >10 gram-scale). More importantly, convergent paired electrolysis, the ideal but challenging electrochemical technology, was employed to transform low-value alcohols into more useful alcohols. Detailed mechanism study suggests that two plausible pathways are involved in the redox neutral alpha-arylation of benzylic alcohols.

Product Details of 100-83-4. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Synthesis of 17 beta-hydroxysteroid dehydrogenase type 10 steroidal inhibitors: Selectivity, metabolic stability and enhanced potency published in 2021, Reprint Addresses Poirier, D (corresponding author), CHU Quebec, Donald Poirier Lab Med Chem, Res Ctr, CHUL, T4-42,2705 Laurier Blvd, Quebec City, PQ G1V 4G2, Canada.. The CAS is 100-83-4. Through research, I have a further understanding and discovery of 3-Hydroxybenzaldehyde.

17beta-Hydroxysteroid dehydrogenase type 10 (17 beta-HSD10) is the only mitochondrial member of 17 beta-HSD family. This enzyme can oxidize estradiol (E2) into estrone (E1), thus reducing concentration of this neuroprotective steroid. Since 17 beta-HSD10 possesses properties that suggest a possible role in Alzheimer’s disease, its inhibition appears to be a therapeutic strategy. After we identified the androsterone (ADT) derivative 1 as a first steroidal inhibitor of 17 beta-HSD10, new analogs were synthesized to increase the metabolic stability, to improve the selectivity of inhibition over 17 beta-HSD3 and to optimize the inhibitory potency. From six D-ring derivatives of 1 (17-C = O), two compounds (17 beta-H/17 alpha-OH and 17 beta-OH/17aC CH) were more metabolically stable and did not inhibit the 17 beta-HSD3. Moreover, solid phase synthesis was used to extend the molecular diversity on the 3b-piperazinylmethyl group of the steroid base core. Eight over 120 new derivatives were more potent inhibitors than 1 for the transformation of E2 to E1, with the 4-(4-trifluoromethyl-3-methoxybenzyl)piperazin-1-ylmethyl-ADT (D-3,7) being 16 times more potent (IC50 = 0.14 mM). Finally, D-ring modification of D-3,7 provided 17 beta-OH/17 alpha-C CH derivative 25 and 17 beta-H/17 alpha-OH derivative 26, which were more potent inhibitor than 1 (1.8 and 2.4 times, respectively).

Pyrrolizidine alkaloids (PAs) are genotoxic carcinogenic phytotoxins mostly prevalent in the Boraginaceae, Asteraceae and Fabaceae families. Heliotropium species (Boraginaceae) are PA-producing weeds, widely distributed in the Mediterranean region, that have been implicated with lethal intoxications in livestock and humans. In Israel, H. europaeum, H. rotundifolium and H. suaveolens are the most prevalent species. The toxicity of PA-producing plants depends on the PA concentration and composition. PAs occur in plants as mixtures of dozens of various PA congeners. Hence, the risk arising from simultaneous exposure to different congeners has to be evaluated. The comparative risk evaluation of the three Heliotropium species was based on recently proposed interim relative potency (iREP) factors, which take into account certain structural features as well as in vitro and in vivo toxicity data obtained for several PAs of different classes. The aim of the present study was to determine the PA profile of the major organ parts of H. europaeum, H. rotundifolium and H. suaveolens in order to assess the plants’ relative toxic potential by utilizing the iREP concept. In total, 31 different PAs were found, among which 20 PAs were described for the first time for H. rotundifolium and H. suaveolens. The most prominent PAs were heliotrine-N-oxide, europine-N-oxide and lasiocarpine-N-oxide. Europine-N-oxide displayed significant differences among the three species. The PA levels ranged between 0.5 and 5% of the dry weight. The flowers of the three species were rich in PAs, while the PA content in the root and flowers of H. europaeum was higher than that of the other species. H. europaeum was found to pose a higher risk to mammals than H. rotundifolium, whereas no differences were found between H. europaeum and H. suaveolens as well as H. suaveolens and H. rotundifolium.

I found the field of Chemistry very interesting.

The selective N-alkylation of anilines with benzylic alcohols can be switched in favor of the dehydrogenative condensation process using the nitrile-ligated Knolker’s complex by conducting the reaction either in a closed system under inert conditions, or in an open system in air. The selective formation of imines, containing reactive C=N bonds, provides an opportunity towards further functionalization. Indeed, a one-pot three-component condensation of alcohols, amines and phosphites, promoted by an iron-based Knolker-type complex in combination with a chiral BINOL-based phosphoric acid, provides access to enantioenriched -N-alkylaminophosphonates.

Conventional detection and identification of the fungi causing postharvest diseases in fruits are time-consuming, laborious, and can only be performed after the manifestation of symptoms. In this work, an alternative method based on headspace analysis, and which allows the early detection of fungi species frequently found papaya fruit, is presented. Volatile compounds of four in vitro fungi cultures (Alternaria alternata, Colletotrichum gloeosporioides, Fusarium solani, and Lasiodiplodia theobromae) were extracted using solid-phase microextraction (SPME) and analyzed by gas chromatography coupled with mass spectrometry. The resulting chromatographic fingerprints were explored by conventional principal component analysis (PCA) and analysis of variance (ANOVA)-PCA. Decomposition of the original matrix, according to the factors proposed in the experimental design, by ANOVA before applying the PCA improved the distinction of the control and fungi samples. The main chromatographic peaks referring to the metabolites produced by each species were successfully identified using the proposed analysis. A primary alcohol with five carbons and phenylethyl alcohol were observed in all fungi species and so could be used as an indicative of postharvest disease. Although unique metabolites were detected for all fungi species, only those from C. gloeosporioides and another from F. solani could be surely identified, such as thymolmethyl and 3,6-dimethylhept-6-en-4-yn-3-ol, respectively. The in vitro results obtained are promising, and it is expected that the biomarkers detected in this work will be useful in future development of methods for the early detection and classification of papaya fungi species.

A series of seven new (1, 3, 6, 7, 10, 12, and 13) and six (2, 4, 5, 8, 9, and 11) known diarylpentanoid analogs were synthesized and assessed for their nitric oxide (NO) and alpha-glucosidase inhibitory activities as well as their antioxidant capacity. Nine compounds (2, 3, 4, 5, 6, 8, 11, 12, and 13) were found to exhibit comparable activity to that of curcumin (IC50 = 13.0 mu M), in which compound 8 has displayed strongest NO inhibitory activity with the IC50 values of 17.5 mu M. Meanwhile, four compounds (1, 7, 12, and 13) were found to possess better alpha-glucosidase inhibitory activity than that of curcumin (30.9 mu M), with the IC50 values ranging from 19.4 to 24.9 mu M. On the other hand, none of the synthesized compounds has achieved better DPPH scavenging activities than that of curcumin, indicating the relatively poor antioxidant potential of desired diarylpentanoid structure. Structure-activity relationship (SAR) study disclosed that the existence of meta-hydroxyphenyl and bromo groups is crucial for antiinflammatory and anti-alpha-glucosidase activities, respectively. Molecular docking study showed that bromo moiety could form additional hydrophobic contacts with alpha-glucosidase, thereby increased the inhibition of diarylpentanoid against alpha-glucosidase. The overall results suggested that diarylpentanoids with poly-meta-hydroxylated phenyl ring and multiple bromo groups may lead to the discovery of new diarylpentanoids with both antiinflammatory and anti-alpha-glucosidase activities.
