Discovery of 3-((dimethylamino)methyl)-4-hydroxy-4-(3-methoxypheny1)-N-phenylpiperidine-1-carboxamide as novel potent analgesic

Management of moderate to severe pain by clinically used opioid analgesics is associated with a plethora of side effects. Despite many efforts have been dedicated to reduce undesirable side effects, moderate progress has been made. In this work, starting from Tramadol, a series of 3-((dimethylamino)methyl)-4hydroxy-4-(3-methoxyphenyl)piperidine-1-carboxamide derivatives were designed and synthesized, and their in vitro and in vivo activities were evaluated. Our campaign afforded selective opioid receptor (MOR) ligand 2a (K-i (MOR): 7.3 +/- 0.5 nM; K-iDOR: 849.4 +/- 96.6 nM; K-i KOR: 49.1 +/- 6.9 nM) as potent analgesic with ED50 of 3.1 mg/kg in 55 degrees C hot plate model. Its antinociception effect was blocked by opioid antagonist naloxone. High binding affinity toward MOR of compound 2a was associated with water bridge, salt bridge, hydrogen bond and hydrophobic interaction with MOR. The high selectivity of compound 2a for MOR over delta opioid receptor (DOR) and kappa opioid receptor (KOR) was due to steric hindrance of compound 2a with DOR and KOR. 2a, a compound with novel scaffold, could serve as a lead for the development of novel opioid ligands.

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.

Application of 477600-74-1, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 477600-74-1 is helpful to your research.

The genus Cassia L.: Ethnopharmacological and phytochemical overview

Nature gifts medicinal plants with the untapped and boundless treasure of active chemical constituents with significant therapeutic potential that makes these plants a beneficial source in the development of phytomedicines. Genus Cassia, with approximately 500 species, is a large group of flowering plants in the family Fabaceae. Cassia species are widely distributed throughout different regions mainly tropical Asia, North America, and East Africa. In the folk medicinal history, these plants are used as laxative and purgative agents. In the Ayurveda system of medicine, they are used to cure headache and fever. Cassia plants exhibit pharmacological activities at large scales such as antimicrobial, anticancer, antiinflammatory, antioxidant, hypoglycemic, hyperglycemic, antimutagenic, and antivirals. The phytochemical investigations of genus Cassia demonstrate the presence of more than 200 chemical compounds, including piperidine alkaloids, anthracene derivatives (anthraquinones), flavonoids, pentacyclic triterpenoids, sterols, phenylpropanoids, and gamma-naphthopyrones. The literature illustrated anthraquinones and flavonoids as major secondary metabolites from this genus. However, some Cassia plants, with rich contents of anthraquinones, still show toxicology properties. As Cassia plants are used extensively in the herbal system of medicine, but only senna dosage forms have achieved the status of the pharmaceutical market as standard laxative agents. In conclusion, further investigations on isolating newer biologically active constituents, unknown underlying mechanisms, toxicology profiles, and clinical studies of Cassia species are needed to be explored. This review article specifies the systematic breach existing between the current scientific knowledge and the fundamentals for the marketization of genus Cassia products.

5-Methylene N-acyl dihydropyridazinium ions as novel Mannich-type acceptors in 1,4 additions of nucleophiles

1,4,5,6-Tetrahydropyridazine featuring an iminium cation flanked by an exocyclic double bond was successfully employed as an N-acyliminium acceptor. Thus, in the presence of a Lewis acid (BF3 center dot OEt2), generation and in situ interception of 5-methylene N-acyl dihydropyridazinium species with a range of various nucleophiles afforded diversified and functionalized 5-methylenyl-1,4-dihydropyridazine derivatives in good yields with excellent gamma’-regioselectivity.

Synthesis and styrene copolymerization of novel trisubstituted ethylenes: 11. Halogen ring-substituted propyl 2-cyano-3-phenyl-2-propenoates

Novel trisubstituted ethylenes, ring-substituted propyl 2-cyano-3-phenyl-2-propenoates, RPhCH=C(CN)CO2C3H7 (where R is 4-chloro-3-fluoro, 2-fluoro-5-iodo, 2-fluoro-6-iodo, 2-trifluoromethyl, 3-trifluoromethyl, 4-trifluoromethyl, 2-trifluoromethoxy, 3-trifluoromethoxy, and 4-trifluoromethoxy) were prepared and copolymerized with styrene. The ethylenes were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and propyl cyanoacetate and characterized by CHN analysis, FTIR, H-1 and C-13 NMR. All the ethylenes were copolymerized with styrene in solution with radical initiation (ABCN) at 70 degrees C. The composition of the copolymers was calculated from nitrogen analysis, and the structures were analyzed by FTIR, H-1 and C-13 NMR. Decomposition of the copolymers in nitrogen (TGA) occurred in two steps, first in the 250-500 degrees C range with residue (0.5-3.1% wt.), which then decomposed in the 500-700 degrees C range.

Four xanthenyl-derived compounds: a comparative investigation of their host behaviour in the presence potential saturated and unsaturated heterocyclic six-membered ring guest solvents

Four xanthenyl-derived host compounds, namely trans-N,N ‘-bis(9-phenyl-9-xanthenyl)cyclohexane-1,4-diamine (1,4-DAX), trans-N,N ‘-bis(9-phenyl-9-thioxanthenyl)cyclohexane-1,4-diamine (1,4-DAT), N,N ‘-bis(9-cyclohexyl-9-xanthenyl)ethylenediamine (OED) and N,N ‘-bis(9-cyclohexyl-9-thioxanthenyl)ethylenediamine (SED) were assessed for their selectivity behaviour in the presence of both the saturated and unsaturated heterocyclic six-membered ring guest solvents morpholine (MOR), piperidine (PIP), dioxane (DIO) and pyridine (PYR). Related compounds OED and SED behaved similarly when each was recrystallized from mixtures of these guests, both selecting for MOR and discriminating against PYR, while, surprisingly, the performance of structurally-similar 1,4-DAX and 1,4-DAT in equivalent conditions, on the other hand, was entirely contrasting: only 1,4-DAX formed complexes from such guest mixtures and 1,4-DAT failed to do so in each instance. Furthermore, 1,4-DAX preferred PYR, an observation distinct from that of OED and SED. Single crystal diffraction (SCXRD) experiments were carried out on suitable crystals formed by 1,4-DAX with these guests, and it was revealed that the preference for PYR may be attributed to both host-guest pi-pi interactions and a shorter H-bond between molecules of the host and PYR compared with other complexes. SCXRD experiments were not possible for OED, SED and 1,4-DAT owing to either the inability of the host compound to complex with these guests or poor crystal quality of the resultant complexes.

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.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 188111-79-7 is helpful to your research. SDS of cas: 188111-79-7.

Heterogeneous Aza-Michael Addition Reaction by the Copper-Based Metal-Organic Framework (CuBTC)

The copper benzene-1, 3, 5-tricarboxylate metal-organic framework (CuBTC) was found to be an effective heterogeneous catalyst for the aza-Michael addition reaction of the four types of amines to electron deficient alkenes at room temperature. The catalytic protocol showed high product yields and outstanding chemo selectivity. The cyclic amines (piperidine and pyrrolidine) and aliphatic amines (n-dibutylamine) provided aza-Michael addition with a high yield of product (similar to 98%) within shorter reaction period (2 h) at room temperature under mild reaction conditions using CuBTC. However, it was observed that the aza-Michael reaction proceeded more slowly, giving 62% yield of product after 24 h in the case of aromatic amine (aniline) with n-butyl acrylate in the presence of CuBTC under identical reaction conditions. The catalyst could be reused four recycles without losing its initial catalytic activity and selectivity. XRD and SEM analysis further confirmed that the crystallinity of catalyst was retained during the reaction. A reaction mechanism is proposed for the aza-Michael addition reaction over heterogeneous CuBTC catalyst. [GRAPHICS] .

Synthesis of ERB-1 by a steam-environment crystallization method and further application in the post-synthesis of Ti-MWW zeolite

Sustainable synthesis of MWW zeolites have been the focus of attention but still a significant challenge. In this study, an innovative synthesis strategy of the EniRicerche-Boralite-1 (ERB-1) precursor is reported via an interesting steam-environment crystallization method (SEC). Compared with the conventional hydrothermal synthesis, this method not only simplified the synthetic process but also reduced 85% amount of boric acid and solvent and half amount of the piperidine (PI, SDA, structure-directing agent). Moreover, the crystallization time was also reduced from 7 d to 2 d. The Ti-MWW prepared with this ERB-1 precursor showed the same catalytic performance as typical post-synthesized Ti-MWW (Ti-MWW-PS) in the liquid-phase epoxidation of 1-hexene with H2O2. XRD and SEM techniques explained the effects of boron content and crystallization time on the preparation of ERB-1. The physicochemical properties of the ERB-1 and corresponding Ti-MWW in different preparation conditions were investigated systematically by the FT-IR, UV-vis, ICP, NH3-TPD and N-2 absorption-desorption techniques. This method is both eco-friendly for the synthesis of ERB-1 and effective for the preparation of MWW-type zeolites in industrial production on a large scale in the future.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 108-26-9. HPLC of Formula: C4H6N2O.
