Discovery of benzisoxazoles as potent inhibitors of chaperone heat shock protein 90

Heat shock protein 90 (Hsp90) is a molecular chaperone that is responsible for activating many signaling proteins and is a promising target in tumor biology. We have identified small-molecule benzisoxazole derivatives as Hsp90 inhibitors. Crystallographic studies show that these compounds bind in the ATP binding pocket interacting with the Asp93. Structure based optimization led to the identification of potent analogues, such as 13, with good biochemical profiles.

Design, synthesis and biological evaluation of N-hydroxy- aminobenzyloxyarylamide analogues as novel selective kappa opioid receptor antagonists

Aminobenzyloxyarylamide derivatives la-i and 2a-t were designed and synthesized as novel selective kappa opioid receptor (KOR) antagonists. The benzoyl amide moiety of LY2456302 was changed into N-hydroxybenzamide and benzisoxazole-3(2H)-one to investigate whether it could increase the binding affinity or selectivity for KOR. All target compounds were evaluated in radioligand binding assays for opioid receptor binding affinity. These efforts led to the identification of compound lc (kappa K-i = 179.9 nM), which exhibited high affinity for KOR. Moreover, the selectivity of KOR over MOR and DOR increased nearly 2-fold and 7-fold, respectively, compared with ( +/- )LY2456302.

Identification of the structural requirements of the receptor-binding affinity of diphenolic azoles to estrogen receptors alpha and beta by three-dimensional quantitative structure-activity relationship and structure-activity relationship analysis

Three-dimensional (31)) quantitative structure-activity relationship (QSAR) and structure-activity relationship (SAR) analyses were applied concurrently to a data set of highly selective estrogen receptor beta (ER beta) agonists. The data set consisted of diphenolic azoles characterized by similar structural skeletons but with different binding modes to the estrogen receptor site. Models were developed separately with respect to the relative binding affinities (RBAs) to ER alpha and ER beta. Steric and electrostatic fields were calculated for a training set of 72 compounds using comparative molecular field analysis (CoMFA). The model developed for ER alpha RBA yielded R-2 of 0.91 and q(cv)(2) of 0.60. The model developed for ER beta RBA yielded R-2 of 0.95 and q(cv)(2) of 0.40. Both models were validated successfully using an external test set of 32 compounds. A new concept of test set evaluation based on the variability of the biological response due to the variability of the living organism has been introduced. The CoMFA analysis was supported by a SAR study. In addition to the most favorable steric and electrostatic regions identified by CoMFA, a number of structural descriptors were identified as being important for binding. These are the number of substituents attached to the main skeleton of each compound, the largest distance between the oxygen atoms of each molecule, and the angle defined by the planes that split the phenyl or the naphthyl and the benzisoxazole or the benzoxazole moiety in a morphometrically longitudinal way.

A systematic review of quality of life and weight gain-related issues in patients treated for severe and persistent mental disorders: focus on aripiprazole

Aripiprazole is a relatively novel second-generation antipsychotic belonging to the chemical class of benzisoxazole derivatives and is characterized by a unique pharmacological profile which suggests that the drug acts as a dopamine-serotonin system stabilizer. Whereas all previously available antipsychotics are antagonists at D-2 receptors, aripiprazole is the only available partial agonist at these receptors. Thus, it has been suggested that aripiprazole could be associated with a relatively neutral impact on bodyweight, possibly reducing risks of a detrimental impact on the quality of life that often complicates management for a large number of patients diagnosed with severe and persistent mental disorders (SPMDs) treated chronically with antipsychotic medications. However, data from short- and long-term reviewed studies indicate that the prevalence rate of clinically relevant weight gain during therapy with this drug is similar to that occurring during treatments with other antipsychotic agents, either typical or atypical. Moreover, information on the impact of aripiprazole therapy on the quality of life of patients diagnosed with SPMDs is scarce and characterized by conflicting results. Given these results, further, large, well-designed studies are needed before confirming potential advantages of aripiprazole over first-generation antipsychotics and other SGAs.

X-Ray Structures of the LXR alpha LBD in Its Homodimeric Form and Implications for Heterodimer Signaling

Liver X receptors (LXRs) are nuclear receptors that are central regulators of cholesterol homeostasis, and synthetic LXR agonists have shown promise as promoters of reverse cholesterol transport and anti-inflammatory agents. Here, we present three X-ray structures of three different agonists bound to the ligand binding domain of LXR alpha. These compounds are GW3965, F(3)methylAA, and a benzisoxazole urea, and we show that these diverse chemical scaffolds address common structural themes, leading to high binding affinity for LXR. Our structures show the LXR ligand binding domain in its homodimeric form, an arrangement previously thought to be stereochemically difficult. A comparison with existing structures of the LXR beta homodimer and LXR alpha:RXR (retinoid X receptor) heterodimers explains differences in dimer affinity and leads us to propose a model for allosteric activation in nuclear receptor dimers, in which an unactivated RXR partner provides an inhibitory tail wrap to the cofactor binding pocket of LXR.

Death following an intramuscular injection of paliperidone: A case report

Paliperidone (9-hydroxyrisperidone), the primary active metabolite of risperidone, is a benzisoxazole derivative of the second-generation antipsychotics. Paliperidone patmitate or PP (the patmitate ester of paliperidone) is available as a once-daily oral tablet, a once-monthly injection or PP1M, and a 3-monthly injection or PP3M (marketed under the name of Trevicta (R) in the European Union). Despite the recent availability of PP3M, several cases of intoxication have been reported worldwide, including lethal cases. However, in Europe, no case of fatal poising has been reported to date. A 33-year-old man was found dead in his room at his parents’ home. His only medical background was a history of schizophrenia. The external examination was without any particularity except a runny nose of brownish liquid with an alcoholic smell. Given the context and the tack of evidence of a third party intervention, an autopsy was not considered necessary. Toxicological analysis of right femoral blood highlighted the presence of paliperidone (240 mu g/ L) only. The risk associated with the use of PP3M formulation is still imperfectly evaluated and several cases of intoxication have been reported worldwide, including fatal cases. In this case, paliperidone poisoning appears to be the highly likely cause of death. In fact, the blood concentration of paliperidone is high, twice the toxicity threshold used in therapeutic monitoring, and no other substances have been identified. This case highlights: the necessity to always evaluate the benefit-risk balance when prescribing this sustained-release form of paliperidone and the difficulties in interpreting paliperidone concentration in forensic cases.

High-performance liquid chromatographic assay of zonisamide (1,2-benzisoxazole-3-methanesulfonamide) in human plasma using a solid-phase extraction technique

A selective and sensitive liquid chromatographic method was developed for the determination of zonisamide in small volumes of plasma. Zonisamide and the internal standard methyl 4-hydroxybenzoate were extracted from 0.2 mL. of plasma with solid-phase extraction columns and eluted with methanol. Analysis of the extracts was performed on a Symmetry C-18 column with ultra-violet spectrophotometric detection. The calibration curve was linear over the concentration range of 0.05-5 mug mL(-1) in plasma. Recoveries were reasonable for routine analyses; the limit of quantification was 0.05 mug mL(-1) with a signal-to-noise ratio of 5. This method could be useful for the pharmacokinetic study of zonisamide in a limited volume of human plasma and for therapeutic drug monitoring.

A redox-mediated Kemp eliminase

The acid/base-catalysed Kemp elimination of 5-nitro-benzisoxazole forming 2-cyano-4-nitrophenol has long served as a design platform of enzymes with non-natural reactions, providing new mechanistic insights in protein science. Here we describe an alternative concept based on redox catalysis by P450-BM3, leading to the same Kemp product via a fundamentally different mechanism. QM/MM computations show that it involves coordination of the substrate’s N-atom to haem-Fe(II) with electron transfer and concomitant N-O heterolysis liberating an intermediate having a nitrogen radical moiety Fe(III)-N-center dot and a phenoxyl anion. Product formation occurs by bond rotation and H-transfer. Two rationally chosen point mutations cause a notable increase in activity. The results shed light on the prevailing mechanistic uncertainties in human P450-catalysed metabolism of the immunomodulatory drug leflunomide, which likewise undergoes redox-mediated Kemp elimination by P450-BM3. Other isoxazole-based pharmaceuticals are probably also metabolized by a redox mechanism. Our work provides a basis for designing future artificial enzymes.
