Use of an efficient polystyrene-supported cerium catalyst for one-pot multicomponent synthesis of spiro-piperidine derivatives and click reactions in green solvent

One-pot multicomponent reactions are very demanding in synthetic organic chemistry. Here we report a new polystyrene-supported cerium catalyst (PS-Ce-amtp) obtained via an easy two-step procedure, which was thoroughly characterized using various techniques. PS-Ce-amtp catalyses the environmentally benign one-pot multicomponent synthesis of spiro-piperidine derivatives through the reaction of substituted aniline, cyclic active methylene compound and formaldehyde at room temperature. The catalyst also exhibits excellent catalytic activity in one-pot synthesis of 1,4-disubstituted 1,2,3-triazoles via click reaction between in situ generated azides (derived from anilines and amines) and terminal alkynes. The catalyst can be recovered easily after reaction and reused five times without significant loss in its catalytic activity. The advantageous features of this catalyst are atom economy, operational simplicity, short reaction times, easy handling and high recycling efficiency.

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 4005-49-6 help many people in the next few years. Safety of N-(7H-Purin-6-yl)benzamide.

Structural Basis for the Inhibition of Mycobacterial MmpL3 by NITD-349 and SPIRO

Novel antitubercular agents are urgently needed to combat the emergence of global drug resistance to human tuberculosis. Mycobacterial membrane protein Large 3 (MmpL3) is a promising drug target because its activity is essential and required for cell-wall biosynthesis. Several classes of MmpL3 inhibitors have been developed against Mycobacterium tuberculosis (Mtb) with potent anti-tuberculosis activity. These include the drug candidate SQ109, which has progressed to phase IIb/III clinical trials. Here, we have determined the crystal structures of MmpL3 in complex with NITD-349 and SPIRO. Both inhibitors bind deep in the central channel of transmembrane domain and cause conformational changes to the protein. The amide nitrogen and indole nitrogen of NITD-349 and the piperidine nitrogen of SPIRO interact and clamp Asp645. Structural analysis of the two structures reveals that these inhibitors target the proton relay pathway to block the activity of MmpL3. The findings presented here enrich our understanding of the binding modes of MmpL3 inhibitors and provide directions to enable further rational drug design targeting MmpL3. (C) 2020 Elsevier Ltd.

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.

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.

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.

With optically active chiral d-hydroxy ester (S)-4 and chiral 1,5-diol (R)-5 obtained by asymmetric hydrogenation of racemic ethyl 5-hydroxyoctanoate (rac-4) with chiral spiro iridium catalyst Ir-(R)-SpiroPAP as chiral starting materials, the efficient enantioselective syntheses of (-)-indolizidine 167B and (+)-coniine were achieved by using intramolecular reductive amination and N-substitution/cyclization, respectively, as a key step to construct the chiral aza-bicyclic[4.3.0]nonane skeleton and chiral piperidine ring.

Arynes as Radical Acceptors: TEMPO-Mediated Cascades Comprising Addition, Cyclization, and Trapping

The application of arynes as radical acceptors is described. The stable radical TEMPO (2,2,6,6-tetramethyl piperidine 1-oxyl) is shown to add to various ortho-substituted benzynes generating the corresponding aryl radicals which engage in 5-exo or 6-endo cyclizations. The cyclized radicals are eventually trapped by TEMPO. The introduced method provides ready access to various dihydrobenzofurans, oxindoles, and sultones by a conceptually novel approach.

Design, synthesis, evaluation and molecular modeling studies of some novel N-substituted piperidine-3-carboxylic acid derivatives as potential anticonvulsants

Novel Schiff bases of 1-(2-Aminoethyl)piperidine-3-carboxylic acid were synthesized, characterized and screened for anticonvulsant activity. Compounds were evaluated for in vitro blood-brain barrier (BBB) permeability by parallel artificial membrane permeability BBB assay (PAMPA-BBB). Compounds 5d, 5f, 5j, 5l, 5m, 5n, 5w, 5x and 5y elicited considerable in vitro permeability across BBB and further screened for in vivo anticonvulsant activity by sc-PTZ and DMCM-induced seizure models. The outcome of the in vivo models suggested that 5d, 5w, and 5y were most potent amongst the synthesized compounds. The neurotoxicity evaluation of 5d, 5w, and 5y by rotarod indicates no impairment of muscle coordination in comparison to standard diazepam. The MTT assay revealed that the test compounds (5d, 5w, and 5y) were not found to alter the cell viability considerably. In silico molecular docking and dynamics simulations were carried out on the homology modeled protein of human GABA transporter 1 (GAT1), which exhibited complementary interactions of compound 5w within the active binding pocket.
