Novel isoxazole carboxamides as growth hormone secretagogue receptor (GHS-R) antagonists

Novel isoxazole carboxamides have been identified as growth hormone secretagogue receptor (GHS-R) antagonists. Substituent modification off the 5-position of the isoxazole ring led to analogues with potent binding affinity and functional antagonism of GHS-R. A potent analogue (32) with high aqueous solubility and good GPCR selectivity was also identified as a potential pharmacological tool for in vivo studies. (C) 2004 Elsevier Ltd. All rights reserved.

Novel ring transformation of 5-(2,3,5-tri-O-benzoyl-beta-D-ribofuranosyl)-isoxazole-4-carbaldehyde with 1,2-diaminobenzenes to 3-cyano-1,5-benzodiazepine C-nucleosides

Syntheses of 3-cyano-7- and 8-substituted-4-(beta -D-ribofuranosyl)-1H-1,5-benzodiazepines were reported. Treatment of isoxazole carbaldehyde with 1,2-diamino-4-nitrobenzene in chloroform gave a Schiffs base, 4-(2-amino-5-nitrophenyl)iminomethyl-5-(2,3,5-tri-O-benzoyl-beta -D-ribofuranosyl)isoxazole in 82% yield with no trace of the other regioisomer. The cyclocondensation of the resulting Schiffs base in benzene containing trifluoroacetic acid (TFA) gave 3-cyano-8-nitro-4-(2,3,5-tri-O-benzoyl-beta -D-rbofuranosyl)-1H-1,5-benzodiazepine in 49% yield. The same reac tion of isoxazole carbaldeyde with 1,2-diamino-4-methoxy- and 4-chlorobenzenes afforded the corresponding Schiffs bases. Extending the reaction time for Schiff’s base gave the corresponding cyanobenzodiazepines in good yields. Debenzoylation of the compounds with sodium methoxide produced deprotected C-nucleosides.

Novel Hybrid Molecules of Isoxazole Chalcone Derivatives: Synthesis and Study of In Vitro Cytotoxic Activities

Background: Now-a-days, the model of hybrid drugs has acquired recognition in medicine due to their significant role in the treatment of different health problems. Methods: We have synthesized new series of isoxazole-chalcone conjugates (14a-m) by the Claisen-Schmidt condensation of suitable substituted acetophenones with isoxazole aldehydes (12a-d). In vitro cytotoxic activity of the synthesized compounds was studied against four different selected human cancer cell lines by using sulforhodamine B (SRB) method. Results: The adopted scheme resulted in good yields of new series of isoxazole-chalcone conjugates (14a-m). Potent cytotoxic activity was observed for compounds -14a, 14b, 14e, 14i, 14j and 14k against prostate DU-145 cancer cell line. Conclusion: The observed potent cytotoxic activities were due to the presence of 3,4,5-trimethoxyphenyl group.

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 199327-61-2, in my other articles.

Polymorphic and solvate structures of ethyl ester and carboxylic acid derivatives of WIN 61893 analogue and their stability in solution

3-Ethyl ester- (1) and 3-carboxylic acid-isoxazole (2) derivatives of an antiviral drug analogue WIN 61893 were synthesized and characterized by X-ray crystallography and NMR spectroscopy. Crystallization experiments afforded two polymorphic structures for the ethyl ester derivative and two solvate structures for the carboxylic acid derivative based on their ability to form intermolecular hydrogen bonding interactions with the solvent molecules. The conformations of the derivatives depended greatly on the orientation of the planar isoxazole and phenyl-oxadiazole ring systems with respect to one another and were found to take up perpendicular, linear or tilted conformations. The carboxylic acid derivative was furthermore observed to undergo isoxazole ring cleavage by decarboxylation in DMSO solution and transforming into a beta-keto nitrile ring-opening product over several days, whereas, the isoxazole ring of the ethyl ester derivative was not affected.

Effect of isoxazole derivatives of tetrahydrofuran neolignans on intracellular amastigotes of Leishmania (Leishmania) amazonensis: A structure-activity relationship comparative study with triazole-neolignan-based compounds

Isoxazole analogues derived from the neolignans veraguensin, grandisin, and machilin G were previously synthesized with different substitution patterns through the bioisosterism strategy. These compounds were tested on intracellular amastigotes of Leishmania (Leishmania) amazonensis; the derivatives proved to be active against intracellular amastigotes, with IC50 values ranging from 0.4 to 25 mu M. The most active analogues were 4 ‘, 14 ‘, 15 ‘, and 18 ‘, with IC50 values of 0.9, 0.4, 0.7, and 1.4 mu M, respectively, showing high selectivity indexes (SI = 277.0; 625.0; 178.5 and 357.1). Overall, the isoxazole analogues did not induce nitric oxide (NO) production by infected cells; there was no evidence that NO influences the antileishmanial mechanism of action, except for compound 4 ‘. Trimethoxy groups as substituents seemed to be critical for antileishmanial activity. The SAR study demonstrated that the isoxazole compounds were more active than 1,2,3-triazole compounds with the same substitution pattterns, demonstrating the importance of the bioisosterism strategy in drug design.
