New optimized piperamide analogues with potent in vivo hypotensive properties

We describe herein the structural optimization of new piperamide analogues, designed from two natural prototypes, piperine 1 and piper-dardine 2, obtained from Piper tuberculatum Jacq. (Piperaceae). Molecular modeling studies using semiempirical AMI method were made in order to establish rational modifications to optimize them by molecular simplification. The targeted compounds (10) and (11) were respectively obtained using benzaldehyde (12) and para-anisaldehyde (13) as starting materials. H-1 NMR spectra showed that the target compounds were diastereoselectively obtained as the (E)-isomer, the same geometry of the natural prototypes. These new synthetic amides presented significant hypotensive effects in cardiovascular essays using in vivo methodologies. Compound 11 (N-[5-(4′-methoxyphenyl)2(E)-pentenoyl]thiomorpholine) showed a potency 10,000 times greater than its prototype 5, evidencing an optimization of the molecular architecture for this class of hypotensive drug candidates.

Evaluation and optimization of synthetic routes from dihydroartemisinin to the alkylamino-artemisinins artemiside and artemisone: A test of N-glycosylation methodologies on a lipophilic peroxide

10-Alkylamino-artemisinins including artemiside and artemisone display enhanced activities against malaria. Earlier, dihydroartemisinin (DHA) TMS ether was converted by trimethylsilyl bromide into the 10-beta-bromide that with amine nucleophiles provided the amino-artemisinins. In an attempt to develop more economic approaches, direct N-glycosylation of DHA was examined but 2-deoxyartemisinin was invariably obtained. However, hydroxyl group activation by conversion into the 10 beta-halide in non-polar solvents with anhydrous HCl and Group I and II metal halides, oxalyl chloride or thionyl chloride with catalytic DMSO, and oxalyl bromide did succeed. The beta-halides were converted in situ by thiomorpholine into artemiside, and by thiomorpholine-1,1-dioxide into artemisone respectively in scalable reactions. Hydrogen peroxide-acetonitrile or the urea-hydrogen peroxide complex efficiently oxidized the sulfide artemiside to the sulfone artemisone. Overall, a generalized approach to 10-alkylamino-artemisinins is now available. (C) 2018 Elsevier Ltd. All rights reserved.

Antihypertensive Properties of a Novel Morphologic Derivative (4-tert-buthyl-2,6-bis(thiomorpholine-4-ilmethyl)phenol)

We evaluated the antihypertensive properties of 4-tert-buthyl-2,6-bis(thiomorpholine-4-ilmethyl)phenol (TBTIF). Spontaneously hypertensive rats were treated with TBTIF or captopril (both at 1 mg center dot kg(-1)center dot d(-1) intramuscularly for 4 days), and their blood pressure (BP) was assessed. In some experiments, concentration response curves to angiotensin I or angiotensin II were generated in rat aortic rings and in the absence or presence of Ang-(1-7), N-G-monomethyl l-arginine, or both; additionally, the angiotensin-converting enzyme (ACE) and ACE2 mRNA levels were quantified in the aortic rings using reverse transcription-polymerase chain reaction. TBTIF diminished BP and reduced angiotensin I- or angiotensin II-induced vasoconstriction. The presence of Ang-(1-7) induced a greater reduction in vasoconstriction, and this effect was reversed by l-N-G-monomethyl arginine. Moreover, TBTIF decreased the mRNA of ACE and increased the mRNA of ACE2. In conclusion, TBTIF diminished rat BP through nitric oxide-dependent and nitric oxide-independent mechanisms. In contrast to captopril, TBTIF exhibits better antihypertensive properties through mechanisms that involve ACE2.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 696-62-8, you can contact me at any time and look forward to more communication.

Anti-inflammatory and Hypolipidemic Effect of Novel Conjugates with Trolox and Other Antioxidant Acids

Objectives: A series of esters and amides, incorporating an antioxidant residue, such as trolox or caffeic acid, and various moieties with different biological activities, were synthesised. Results: The obtained compounds demonstrated considerable anti-inflammatory, radical scavenging and antioxidant action. Thus, they could reduce carrageenan-induced rat paw oedema by 31-60% at 150 mu mol/kg and inhibit rat microsomal membrane lipid peroxidation with IC50 values as low as 1.4 mu M which is much lower than that of trolox. Most of them could also inhibit soybean lipoxygenase. The thiomorpholine derivatives decreased significantly all lipidemic indices of Triton-induced hyper-lipidemia in rats. The most active, the caffeic acid derivative (6), decreases triglycerides, total cholesterol and low density lipoprotein, in the plasma of hyperlipidemic rats, by 70%, 67%, and 73%, respectively, at 150 mu mol/kg (i.p.). Conclusion: The synthesised compounds, designed to exhibit two or more pharmacological actions, may be considered useful in the study of agents addressed to conditions involving inflammation and oxidative stress.

Design, Synthesis and Study of Nitrogen Monoxide Donors as Potent Hypolipidaemic and Anti-Inflammatory Agents

Inflammation and oxidative stress are involved in cardiovascular diseases. Nitrogen monoxide participates in the regulation of endothelial processes. Thus, derivatives of classic nonsteroidal anti-inflammatory drugs (NSAIDs), trolox or cinnamic acids esterified with 2-(nitrooxy)ethanol were designed and studied. It was found that the nitrogen monoxide (NO) releasing activity was comparable to that of S-nitroso-N-acetylpenicillamine. The nitrooxy derivatives decreased potently lipid indices in the plasma of hyperlipidaemic rats (30-85%). All compounds presented increased anti-inflammatory activity in vivo, inhibiting carrageenan-induced rat paw oedema as high as 76%, up to six times higher than that of the parent acids. Lipoxygenase inhibitory activity was significant for most of them, although the parent molecules exerted a minor effect (IC50 > 0.2 mM). Those compounds incorporating an antioxidant structure inhibited rat microsomal membrane lipid peroxidation strongly and possessed radical scavenging activity. These results indicated that the described compounds could act at different targets in multifactorial diseases, further limiting the possible adverse effects of drug combinations.

Heterocyclic core analogs of a direct thrombin inhibitor

Thrombin is a serine protease that plays a key role in blood clotting. Pyrrolidine 1 is a potent thrombin inhibitor discovered at Merck several years ago. Seven analogs (2-8) of 1 in which the pyrrolidine core was replaced with various heterocycles were prepared and evaluated for activity against thrombin, clotting factors VIIa, IXa, Xa, and XIIa, and trypsin. The thiomorpholine analog 6 was the most active, essentially matching the thrombin inhibitory activity of 1 with slightly improved selectivity over trypsin. (C) 2014 Elsevier Ltd.

SYNTHESIS AND CHARACTERIZATION OF S,S-, S,S,S-, AND THIOMORPHOLINYL-SUBSTITUTED NITRODIENE COMPOUNDS AND A STRUCTURAL STUDY

S,S- and S,S,S-substituted nitrodienes 3a, 3b, and 4a were synthesized by reactions of 1,1,2,4,4-pentachloro-3-nitro-1,3-butadiene with some thiols 4-chlorobenzylmercaptan and 2-chlorobenzylmercaptan in ethanol in the presence of sodium hydroxide. Thiomorpholine ring substituted nitrodienes 6c and 6d and were obtained from the reactions of the mono(thio)substituted nitrodienes with thiomorpholine in dichloromethane. The single crystal X-ray structure of 4-(1-thiomorpholinyl)-4-(butylsulfanyl)-1,1,2-trichloro-3-nitro-1,3-butadiene (6c) is reported. In this present paper, the structures of new compounds were characterized by using nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), and Fourier transform infrared (FTIR) spectroscopy spectroscopic data.

Redox-Neutral alpha-Sulfenylation of Secondary Amines: Ring-Fused N,S-Acetals

Secondary amines react with thiosalicylaldehydes in the presence of catalytic amounts of acetic acid to generate ring-fused N,S-acetals in redox-neutral fashion. A broad range of amines undergo alpha-sulfenylation, including challenging substrates such morpholine, thiomorpholine, and piperazines. Computational studies employing density functional theory indicate that acetic acid reduces the energy barriers of two separate steps, both of which involve proton transfer.

Development of a Safe and High-Throughput Continuous Manufacturing Approach to 4-(2-Hydroxyethyl)thionnorpholine 1,1-Dioxide

Continuous processing enabled the highly energetic double conjugate addition of ethanolamine to divinylsulfone to prepare 2 kg of 4-(2-hydroxyethyl)thiomorpholine 1,1-dioxide, as an intermediate in the synthesis of HIV Maturation Inhibitor BMS-955176. In situ IR was employed to monitor the steady state of the transformation for increased robustness via appearance of the thiomorpholine dioxide moiety and disappearance of the divinylsulfone. Surprisingly, a series of oligomers formed as intermediates, which converted to product with extended aging or heating, consistent with computational predictions. By running this process in flow, the highly exothermic reaction could be safely executed in an equal volume of water as the only solvent, despite an adiabatic temperature rise of 142 degrees C, leading to a streamlined and efficient process.

Future efforts will undeniably focus on the diversification of the new catalytic transformations.

Novel Functional Ionic Liquids as Metal-Free, Efficient and Recyclable Catalysts for the Carbonylation of Formaldehyde

Methyl glycolate (MG) was synthesized as a precursor to ethylene glycol from the catalytic carbonylation of formaldehyde followed by esterification with methanol by using metal-free, efficient and recyclable SO3H-functionalized ionic liquids (BAILs) as catalysts. Among the studied BAILs, N-butyl-N-(3-sulfonylpropyl) thiomorpholine-1,1-dioxide triflate showed excellent activity and MG selectivity. The effects of reaction parameters such as reactant, solvent, catalyst loading, molar ratio of H2O to H2CO, temperature, pressure, and reaction time were studied. MG was obtained in high yield under mild conditions. At 160 degrees C, 5.0 MPa, and reactant mole ratio of BAIL: H2CO:H2O = 1:40: 80, 98 % conversion of formaldehyde was achieved with 94 % selectivities of MG. Catalysts did not show any significant deterioration in performance in repeated use up to eight batches.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Welcome to check out more blogs about 624-31-7, in my other articles. Category: thiomorpholine.
