Synthesis of Nitrogen- and Oxygen-Containing Heterocycles by Prins Cyclization in Continuous Flow

Aza-silyl-Prins and oxa-Prins cyclization reactions in continuous-flow chemistry are described for the synthesis of the corresponding tetrahydropyridines and pyran derivatives, respectively. In particular, the use of pyridine-carboxaldehydes for aza-silyl-Prins reaction led to either a symmetrical triarylmethane or two new bicyclic compounds. 4-Fluorinated-2-substituted tetrahydropyran derivatives were also obtained in the oxa-Prins cyclization with good selectivity in favor of the anti-isomer.

Alkaloids Modulate the Functioning of Ion Channels Produced by Antimicrobial Agents via an Influence on the Lipid Host

It is widely recognized that an alteration in membrane physical properties induced by the adsorption of various drugs and biologically active compounds might greatly affect the functioning of peptides and proteins embedded in the membrane, in particular various ion channels. This study aimed to obtain deep insight into the diversity of the molecular mechanisms of membrane action of one of the most numerous and extremely important class of phytochemicals, the alkaloids. Protoalkaloids (derivatives of beta-phenylethylamine, benzylamines, and colchicines), heterocyclic alkaloids (derivatives of purine, quinolysidine, piperidine, pyridine, quinoline, and isoquinoline), and steroid alkaloids were tested. We evaluated the effects of 22 compounds on lipid packing by investigating the thermotropic behavior of membrane lipids and the leakage of a fluorescent marker from unilamellar lipid vesicles. The alteration in the transmembrane distribution of the electrical potential was estimated by measuring the alkaloid induced changes in the boundary potential of planar lipid bilayers. We found that benzylamines, the chili pepper active components, capsaicin and dihydrocapsaicin, strongly affect not only the elastic properties of the lipid host, but also its electrostatics by dramatic decrease in membrane dipole potential. We concluded that the increase in the conductance and lifetime of gramicidin A channels induced by benzylamines was related to alteration in membrane dipole potential not to decrease in membrane stiffness. A sharp decrease in the lifetime of single ion pores induced by the antifungal lipopeptide syringomycin E, after addition of benzylamines and black pepper alkaloid piperine, was also mainly due to the reduction in dipole potential. At the same time, we showed that the disordering of membrane lipids in the presence of benzylamines and piperine plays a decisive role in the regulation of the conductance induced by the antifungal polyene macrolide antibiotic nystatin, while the inhibition of steady-state transmembrane current produced by the antimicrobial peptide cecropin A was attributed to both the dipole potential drop and membrane lipid disordering in the presence of pepper alkaloids. These data might lead to a better understanding of the biological activity of alkaloids, especially their action on voltage-gated and mechanosensitive ion channels in cell membranes.

Organocatalytic asymmetric synthesis of highly substituted pyrrolidines bearing a stereogenic quaternary centre at the 3-position+

An organocatalytic asymmetric cascade reaction has been developed for the synthesis of highly substituted pyrrolidines having a stereogenic quaternary centre at the 3-position. N-Tosyl aminomethyl enone and trans–cyano-,-unsaturated ketone were utilized as the reaction partners in this method. Cinchonidine derived bifunctional amino-squaramide catalysts were the best to obtain the products in high enantio- and diastereoselectivities.

Discovery of aryl-piperidine derivatives as potential antipsychotic agents using molecular hybridization strategy

Schizophrenia is a chronic, disabling mental disorder that affects about one percent of world’s population. Drugs acting on multiple targets have been demonstrated to provide superior efficacy in schizophrenia than agents acting on single target. In this study, based on FW01, a selective potent 5-HT1A receptor agonist discovered via dynamic pharmacophore-based virtual screening, molecular hybridization strategy was employed to optimize its in vitro activity over D-2 and 5-HT2A receptors. The optimized compound 9f was found to show dual potent D-2 and 5-HT2A receptors antagonistic activity. In addition, compound 9f showed good in vivo metabolic stability with t(1/2) of 2 h in ICR mice and good capability to penetrate the blood-brain barrier with (K)p value of 4.03. These results demonstrated that the dual D-2 and 5-HT1A receptor antagonist 9f could serve as a promising lead compound to discover potent antipsychotic agents. (c) 2020 Elsevier Masson SAS.

Mechanism of synergistic DNA damage induced by caffeic acid phenethyl ester (CAPE) and Cu(II): Competitive binding between CAPE and DNA with Cu(II)/Cu(I)

Caffeic acid phenethyl ester (CAPE) is an active polyphenol of propolis from honeybee hives, and exhibits antioxidant and interesting pharmacological activities. However, in this study, we found that in the presence of Cu (II), CAPE exhibited pro-oxidative rather than antioxidant effect synergistic DNA damage was induced by the combination of CAPE and Cu(II) together as measured by strand breakage in plasmid DNA and 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG) formation, which is dependent on the molar ratio of CAPE:Cu(II). Production of Cu(I) and H2O2 from the redox reaction between CAPE and Cu(II), and subsequent center dot OH formation was found to be responsible for the synergistic DNA damage. DNA sequencing investigations provided more direct evidence that CAPE/Cu(II) caused preferential cleavage at guanine, thymine and cytosine residues. Interestingly, we found there are competitive binding between CAPE and DNA with Cu(II)/Cu(I), which changed the redox activity of Cu(II)/Cu(I), via complementary applications of different analytical methods. The observed DNA damage was mainly attributed to the formation of DNA-Cu(II)/Cu(I) complexes, which is still redox active and initiated the redox reaction near the binding site between copper and DNA. Based on these data, we proposed that the synergistic DNA damage induced by CAPE/Cu(II) might be due to the competitive binding between CAPE and DNA with Cu, and site-specific production of center dot OH near the binding site of copper with DNA. Our findings may have broad biological implications for future research on the pro-oxidative effects of phenolic compounds in the presence of transition metals.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4395-98-6 help many people in the next few years. HPLC of Formula: C6H10N2.

Khellinoflavanone, a Semisynthetic Derivative of Khellin, Overcomes Benzo[a] pyrene Toxicity in Human Normal and Cancer Cells That Express CYP1A1

Cytochrome P450 family 1 (CYP1) enzymes catalyze the metabolic activation of environmental procarcinogens such as benzo[a] pyrene, B[a] P, into carcinogens, which initiates the process of carcinogenesis. Thus, stopping the metabolic activation of procarcinogens can possibly prevent the onset of cancer. Several natural products have been reported to show unique ability in inhibiting CYP1 enzymes. We found that khellin, a naturally occurring furanochromone from Ammi visnaga, inhibits CYP1A1 enzyme with an IC50 value of 4.02 mu M in CYP1A1-overexpressing human HEK293 suspension cells. To further explore this natural product for discovery of more potent and selective CYP1A1 inhibitors, two sets of semisynthetic derivatives were prepared. Treatment of khellin with alkali results in opening of a pyrone ring, yielding khellinone (2). Claisen-Schmidt condensation of khellinone (2) with various aldehydes in presence of potassium hydroxide, at room temperature, provides a series of furanochalcones 3a-v (khellinochalcones). Treatment of khellinone (2) with aryl aldehydes in the presence of piperidine, under reflux, affords the flavanone series of compounds 4a-p (khellinoflavanones). The khellinoflavanone 4l potently inhibited CYP1A1 with an IC50 value of 140 nM in live cells, with 170fold selectivity over CYP1B1 (IC50 for CYP1B1 = 23.8 mu M). Compound 4l at 3x IC50 concentration for inhibition of CYP1A1 completely protected HEK293 cells from CYP1A1-mediated B[a] P toxicity. Lung cancer cells, A549 (p53+) and Calu-1 (p53null), blocked in growth at the S-phase by B[a] P were restored into the cell cycle by compound 4l. The results presented herein strongly indicate the potential of these khellin derivatives for further development as cancer chemopreventive agents.

Synthesis, biological evaluation, and in silico study of some unique multifunctional 1,2,4-triazole acetamides

The imperative demand for antibacterial agents and enzyme inhibitors prompted us to synthesize some new compounds, 6a-6k, bearing multifunctional moieties. The target acetamides were derived from 4-phenyl-5-(1-tosylpiperidin-4-yl)-4H-1,2,4-triazole-3-thiol (3). The structural analysis was carried out using modern spectroscopic techniques including IR, NMR, and EIMS spectral analysis. The antibacterial activity was screened against five bacterial strains including three gram-negative and two gram-positive ones. Enzyme inhibition was carried out against lipoxygenase enzyme and results were supported by in silico study. The synthesized compounds were proved to be potent antibacterial agents and enzyme inhibitors.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 10465-81-3, in my other articles.

Synthesis of N -substituted 3-(2-aryl-2-oxoethyl) 3-hydroxyindolin-2-ones and their conversion to N -substituted (E)-3-(2-aryl-2-oxoethylidene)indolin-2-ones: synthetic sequence, spectroscopic characterization and structures of four 3-hydroxy compounds and five oxoethylidene products

An operationally simple and time -efficient approach has been developed for the synthesis of racemic N-substituted 3-(2-aryl-2-oxoethyl)-3-hydroxyindolin-2ones by a piperidine-catalysed aldol reaction between aryl methyl ketones and N-alkylisatins. These aldol products were used successfully as strategic intermediates for the preparation of N-substituted (E)-3-(2-hetary1-2-oxoethylidene)indolin-2-ones by a stereoselective dehydration reaction under acidic conditions. The products have all been fully characterized by ‘H and 13C NMR spectroscopy, by mass spectrometry and, for a representative selection, by crystal structure analysis. In each of (RS)-1-benzy1-3-hydroxy 3 [2 (4 methoxypheny1)-2-oxoethyl]indolin-2-one, C24H21N04, (Ic), and (RS)-1-benzy1-3-{214(dimethylamino)pheny11-2-oxoethyll-3-hydroxyindolin-2-one, C25H24N203, (Id), inversion -related pairs of molecules are linked by 0 H 0 hydrogen bonds to form R22(10) rings, which are further linked into chains of rings by a combination of C H 0 and C H -7r(arene) hydrogen bonds in (Ic) and by C H rr(arene) hydrogen bonds in (Id).

New thiazolidine-2,4-dione derivatives combined with organometallic ferrocene: Synthesis, structure and antiparasitic activity

Favourable physicochemical properties of an organometallic ferrocene and antiplasmodial potency of compounds containing the thiazolidine-2,4-dione framework (TZD-4) prompted us to explore compounds containing both the thiazolidine-2,4-dione core and the ferrocenyl unit with the primary aim of identifying compounds with promising antiprotozoal activities. Thus, a new series of rationally designed ferrocene-based thiazolidine-2,4-dione derivatives, containing a selection of secondary cyclic amines, was synthesised and fully characterised using standard spectroscopic techniques. The resulting compounds were screened for their antiplasmodial and antitrypanosomal activities against both the chloroquine-resistant (Dd2) strain of Plasmodium falciparum and the Nagana Trypanosoma brucei brucei 427. The general trend that emerged indicated that the target compounds were more selective towards T. b. brucei compared to the P. falciparum parasite. Moreover, the analogues bearing methylpiperazine (8a) and piperidine (8b) rings were more active against T. b. brucei compared to hit compound TZD-4. Except compound 8b, which appeared promising, none of the synthesised compounds showed better activity than TZD-4 against the P. falciparum parasite. All the synthesised compounds were non-toxic and often showed >90% viability of the HeLa cell line screened.
