Synthesis and Preliminary Antibacterial Evaluation of 2-Butyl Succinate-based Hydroxamate Derivatives Containing Isoxazole Rings

Two series of novel 2-butyl succinate-based Hydroxamate derivatives containing isoxazole rings were synthesized, characterized and evaluated for antibacterial activity. The synthesized compounds were found to exhibit weak to moderate inhibitory activity against Staphytlococcus aureu and Klebsiellar pneumonia in vitro. All the compounds synthesized were found to be more effective against Klebsiellar pneumonia compared to Staphytlococcus aureu.

Identification of an N-oxide pyridine GW4064 analog as a potent FXR agonist

According to the docking studies and the analysis of a co-crystal structure of GW4064 with FXR, a series of 3-aryl heterocyclic isoxazole analogs were designed and synthesized. N-Oxide pyridine analog (7b) was identified as a promising FXR agonist with potent binding affinity and good efficacy, supporting our hypothesis that through an additional hydrogen bond interaction between the pyridine substituent of isoxazole analogs and Tyr373 and Ser336 of FXR, binding affinity and functional activity could be improved.

Synthesis and pharmacological characterization of new analogs of broxaterol

A series of isoxazole derivatives structurally related to broxaterol 1 has been prepared and tested for their potency to beta(1) and beta(2) adrenergic receptors. At variance with broxaterol, none of the tested compounds displayed agonistic activity. The 3-isopropenyl derivative 5f is the most potent antagonist both in the trachea and atria preparations.

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 71119-23-8, in my other articles.

Design, synthesis and cytotoxic activities of scopoletin-isoxazole and scopoletin-pyrazole hybrids

12 novel scopoletin-isoxazole and scopoletin-pyrazole hybrids were designed, synthesized and their chemical structures were confirmed by HR-MS, IR,1H NMR and13C NMR spectra. The anticancer activities of the newly synthesized compounds were evaluated in vitro against three human cancer cell lines including HCT-116, Hun7 and SW620 by MTT assay. The screening results showed that six compounds (9a, 9c, 9d, 12a, 18b and 18d) exhibited potent cytotoxic activities with IC50values below 20?muM. Besides, we have further evaluated the growth inhibitory activities of six compounds against the human normal tissue cell lines HFL-1. Especially, compound 9d displayed significant anti-proliferative activity with IC50values ranging from 8.76?muM to 9.83?muM and weak cytotoxicity with IC50value of 90.9?muM on normal cells HFL-1, which suggested that isoxazole-based hybrids of scopoletin were an effective chemical modification to improve the anticancer activity of scopoletin.

4-((R)-2-{[6-((S)-3-Methoxypyrrolidin-1-yl)-2-phenylpyrimidine-4-carbonyl]amino}-3-phosphonopropionyl)piperazine-1-carboxylic Acid Butyl Ester (ACT-246475) and Its Prodrug (ACT-281959), a Novel P2Y12 Receptor Antagonist with a Wider Therapeutic Window in the Rat Than Clopidogrel

Recent post hoc analyses of several clinical trials with P2Y12 antagonists showed the need for new molecules being fully efficacious as antiplatelet agents and having a reduced propensity to cause major bleeding. We have previously reported the discovery of the 2-phenylpyrimidine-4-carboxamide analogs as P2Y12 antagonists with nanomolar potency in the disease-relevant platelet aggregation assay in human plasma. Herein we present the optimization steps that led to the discovery of clinical candidate ACT-246475 (30d). The key step was the replacement of the carboxylic acid functionality by a phosphonic acid group which delivered the most potent molecules of the program. In addition, low in vivo clearance in rat and dog was achieved for the first time. Since the bioavailability of 30d was low in rat and dog, we developed the bis((isopropoxycarbonyl)oxy)methyl ester prodrug (ACT-281959, 45). Compound 30d showed efficacy in the rat ferric chloride thrombosis model when administered intravenously as parent or orally as its prodrug 45. Moreover, 30d displays a wider therapeutic window as compared to clopidogrel in the rat surgical blood loss model.

Synthesis of Quinolinium Salts from N-Substituted Anilines, Aldehydes, Alkynes, and Acids: Theoretical Understanding of the Mechanism and Regioselectivity

Secondary anilines were first utilized in the four-component coupling of aniline, aldehyde, alkyne, and acid to synthesize a variety of N-substituted quinolinium salts. This method was carried out under mild reaction conditions and exhibited excellent chemo- and regioselectivities. DFT calculation was performed to analyze the cyclization step, where the interaction/distortion model provided better insight into the singular selectivity of terminal/internal alkynes in reaction.

The Reverse Vilsmeier Approach to the Synthesis of Quinolines, Quinolinium Salts and Quinolones

N-Methylformanilide (MFA) reacts with various electron-rich alkenes in POCl3 solution to give N-methylquinolinium salts generally in good yield.The alkenes can be vinyl acetate, an aldehyde or ketone enamine (preferably the morpholine enamine), a methyl aryl ketone (reacting as its enol) or it may be generated from an alkanoamide bearing alpha-protons (which produces an alpha-chloroenamine in situ).The reaction is effective for a variety of other alkyl-, aryl- and benzyl-formanilides as well as ring substituted anilides though electron-withdrawing groups tend to inhibit cyclisation.The mechanism of the cyclisation has been elucidated and shown to involve an electrophilic ?6s process.The reactions of MFA with amides in POCl3 gives 4-quinolones on alkaline workup.

Antimitotic Agents. Alterations at the 2,3-Positions of Ethyl (5-Amino-1,2-dihydropyrido<3,4-b>pyrazin-7-yl)carbamates

The reaction of ethyl (6-amino-4-chloro-5-nitropyridin-2-yl)carbamate (2) with alpha-amino ketone oximes gave 4-<(2-oxoethyl)amino>pyridine oximes 3, which were reductively cyclized to give a series of ethyl (1,2-dihydropyrido<3,4-b>pyrazin-7-yl)carbamates (6).In another approach, alpha-nitro ketones, alpha-oximino ketones, and alpha-nitro alcohols were reduced to give alpha-amino alcohols, which were reacted with 2 to give 4-<(2-hydroxyethyl)amino>pyridines (5).Oxidation of these alcohols with the chromium trioxide-pyridine reagent gave the corresponding ketones (4), which were also reductively cyclized to give 6.Structure-activity relationship studies indicated that alterations at the 2- and 3-positions of the pyrazine ring of 6 had a significant effect on cytotoxicity and the inhibition of mitosis in cultured lymphoid leukemia L1210 cells.Compounds that exhibited in vitro cytotoxicities at less than 1 nM showed the same level of in vivo activity, whereas the less potent compounds showed wide variations in their in vivo activity.
