The HIV-1 capsid (CA) protein plays essential roles in both early and late stages of HIV-1 replication and is considered an important, clinically unexploited therapeutic target. As such, small drug-like molecules that inhibit this critical HIV-1 protein have become a priority for several groups. Therefore, in this study we explore small molecule targeting of the CA protein, and in particular a very attractive inter-protomer pocket. We report the design, parallel synthesis, and anti-HIV-1 activity evaluation of a series of novel phenylalanine derivatives as HIV-1 CA protein inhibitors synthesized via Cu(I)-catalyzed alkyne-azide 1,3-dipolar cycloaddition (CuAAC) reaction. We demonstrate robust inhibitory activity over a range of potencies against the HIV-1 NL4-3 reference strain. In particular, compound 13m exhibited the greatest potency and lowest toxicity within this new series with an EC50 value of 4.33 muM and CC50 value of >57.74 muM (SI > 13.33). These values are very similar to the lead compound PF-74 (EC50 = 5.95 muM, CC50 > 70.50 muM, SI > 11.85) in our assay, despite significant structural difference. Furthermore, we demonstrate via surface plasmon resonance (SPR) binding assays that 13m interacts robustly with recombinant HIV-1 CA and exhibits antiviral activity in both the early and late stages of HIV-1 replication. Overall, the novel parallel synthesis and structure-activity relationships (SARs) identified within this study set the foundation for further rational optimization and discovery of CA-targeting compounds with improved potency.

1,3-Dipolar cycloaddition reaction of trimethylstannylacetylene with nitrile oxides yielded 3-substituted 5-(trimethylstannyl)isoxazoles. On the other hand, the same reaction of (trimethylstannyl)phenylacetylene, -1-hexyne, and -(trimethylsilyl)acetylene gave 3,5-disubstituted 4-(trimethylstannyl)isoxazoles almost regioselectively. The regioselectivity of the cycloaddition reaction is interpreted by application of the frontier-electron theory.

A KI-mediated multi-component cyclocondensation of hydroxylamine hydrochloride, aromatic/hetero-aromatic aldehydes, and ethyl acetoacetate or 4-chloroethyl acetoacetate to form isoxazole-5(4H)-one heterocycles is described. The reaction employs readily accessible starting reactants and provides a range of synthetically isoxazole-5(4H)-ones in good to high yields. Reactions were performed in water as a green medium at room temperature (rt) without heating, microwave irradiation or sonication. Reusability of the reaction medium is also a noteworthy characteristic of this reaction.

The farnesoid X receptor (FXR) is a nuclear receptor that acts as a master regulator of bile acid metabolism and signaling. Activation of FXR inhibits bile acid synthesis and increases bile acid conjugation, transport, and excretion, thereby protecting the liver from the harmful effects of bile accumulation, leading to considerable interest in FXR as a therapeutic target for the treatment of cholestasis and nonalcoholic steatohepatitis. We identified a novel series of highly potent non-bile acid FXR agonists that introduce a bicyclic nortropine-substituted benzothiazole carboxylic acid moiety onto a trisubstituted isoxazole scaffold. Herein, we report the discovery of 1 (tropifexor, LJN452), a novel and highly potent agonist of FXR. Potent in vivo activity was demonstrated in rodent PD models by measuring the induction of FXR target genes in various tissues. Tropifexor has advanced into phase 2 human clinical trials in patients with NASH and PBC.

The new anticonvulsant N-(5′-methylisoxazol-3-yl)-2,6-dimethylbeazamide (D2916), which presents two kinds of methyl groups which could be oxidized, was submitted to various chemical oxidizing agents. Several sites and degrees of oxidation were observed. The main oxidized site was the arylmethyl group without cleavage of the isoxazole ring, leading via carboxylic acid and primary alcohol intermediates to phthalimide and lactame derivatives. In no case was the methyl group of the isoxazole moiety hydroxylated.

This study reports an efficient four-step method to synthesize a series of new (4S,8aS)-3,4-diphenyl-6,7,8,8a-tetrahydro-4H-isoxazolo[3,4-a]pyrrolizines. The first step involves a copper(II) acetylacetonate catalyzed three component coupling of aldehyde, (S)-pyrrolidin-2-ylmethanol, and alkynes (A3 coupling) to form propargylamines (4 a?4 n). The coupling reaction is applicable to various aldehydes, amines, and alkynes and provides the propargylamines in good to excellent yields with excellent distereoselectivities. Products (4 a?4 n) were converted into aldehydes (5 a?5 n) by Swern oxidation, aldehydes (5 a?5 n) were reacted with hydroxyl amine hydrochloride to form aldoxime (6 a?6 n), respectively. Further aldoximes (6 a?6 n) underwent an intramolecular 1,3-dipolar cycloaddition to form tricyclic-fused isoxazoles (7 a?7 n). The 1,3-dipolar cycloaddition reaction tolerates high structural diversity and generated desired products (7 a?7 n) in moderate to good yields and excellent diastereoselectivities. A proposed mechanism for synthesis of 7 a is reported.

The reaction of 1:1 zwitterionic intermediate generated in situ from dibenzoylacetylene and triphenylphosphine with 2-aminobenzimidazole afforded Benzo[4,5]imidazo[1,2-a]pyrimidine in good yields while as the reaction with 2-amino derivatives of benzothiazole, thiazole and isoxazole gave enamine ketones. Protonation of the highly reactive 1:1 intermediate produced in the reaction between alkyl isocyanides and dibenzoylacetylene by aldehydes (containing acidic hydrogen) gave highly functionalized secondary ketenimines. The products were generated in good yields and characterized by standard analytical techniques such as IR, 1H NMR, 13C NMR and mass spectrometry. Single crystal X-ray diffraction has been established for six structures. Short reaction time, good yields, fairly mild conditions and simple work-up procedure are the notable advantages of this synthetic protocol.
