Synthesis and biological evaluation of new N-(4-substituted phenyl)glycine derivatives as potential anti-inflammatory agents

Background: Designing new anti-inflammatory agents possessing safe therapeutic profiles and devoid of potential undesirable side effects is an active field in medicinal chemistry. Thus, a series of N-(4-substituted phenyl)glycine derivatives was designed and synthesized. The idea behind the design is to utilize the bifunctionality of 4-aminoacetophenone via converting the amino group into glycine derivative as a side arm to mimic the glycine amino acid enhancing the overall physicochemical and biological characteristics. In addition, the opposite acetyl group was used as a center for modification and derivatization. Methods: The starting N-(4-acetylphenyl)glycine was converted into two intermediates: the chalcone analog 2 and the thiosemicarbazone derivative 8. Both 2 and 8 were derivatized and/or cyclized into different heterocyclic target derivatives (3-7 and 9-12). The target compounds were screened for anti-inflammatory activity using carrageenan-induced rat paw edema assay. Results: The results showed that compounds 6, 7, and 3, were the most active among the tested compounds at 50 mg/kg dose level with % inhibition of edema of 51.82, 43.80, and 40.39, respectively. Conclusion: The authors succeeded to introduce a simple and versatile skeleton with a side arm resembling the glycine amino acid; imparting a potential improvement in physicochemical properties. We utilize the other side of the skeleton?s aromatic ring as a center for derivatization. The chalcone analog and its cyclized heterocyclic derivatives were of remarkably higher anti-inflammatory activity than the thiosemicarbazone and its derivatives.

Targeting putative components of the mitochondrial permeability transition pore for novel therapeutics

Few discoveries have influenced drug discovery programs more than the finding that mitochondrial membranes undergo swings in permeability in response to cellular perturbations. The conductor of these permeability changes is the aptly named mitochondrial permeability transition pore which, although not yet precisely defined, is comprised of several integral proteins that differentially act to regulate the flux of ions, proteins and metabolic byproducts during the course of cellular physiological functions but also pathophysiological insults. Pursuit of the pore’s exact identity remains a topic of keen interest, but decades of research have unearthed provocative functions for the integral proteins leading to their evaluation to develop novel therapeutics for a wide range of clinical indications. Chief amongst these targeted, integral proteins have been the Voltage Dependent Anion Channel (VDAC) and the F1FO ATP synthase. Research associated with the roles and ligands of VDAC has been extensive and we will expand upon 3 examples of ligand:VDAC interactions for consideration of drug discovery projects: Tubulin:VDAC1, Hexokinase I/II:VDAC1 and olesoxime:VDAC1. The discoveries that cyclosporine blocks mitochondrial permeability transition via binding to cyclophilin D, and that cyclophilin D is an important component of F1FO ATP synthase, has heightened interest in the F1FO ATP synthase as a focal point for drug discovery, and we will discuss 2 plausible campaigns associated with disease indications. To date no drug has emerged from prospective targeting these integral proteins; however, continued exploration such as the approaches suggested in this Commentary will increase the likelihood of providing important therapeutics for severely unmet medical needs.

Impurity Occurrence and Removal in Crystalline Products from Process Reactions

The behavior of impurities when subjected to crystallizations, and related processes such as recrystallization and reslurrying, has been reviewed with a particular focus on the years 2000-2015, but also including significant cases from outside that period. Small molecule pharmaceuticals and similar small organic molecules are included but not biomolecules, inorganics, or minerals. Phase impurities are only covered when a phase transformation is involved with the management of an impurity. Introductory examples illustrating some general features of crystallization as a method of purification are presented, as well as approaches to quantifying the effectiveness of purification. The review classifies cases based on the behavior of the specific impurities covered. The classes of behavior observed are the removal by washing, recrystallization, or reslurrying (Class I), impurities not being removed by these operations (Class II), and impurities which are removed in conjunction with a phase transformation (Class III). Examples of each of these types of behavior are presented, with many processes producing impurities which fall into more than one of these classes. Studies on the inclusion of extraneous molecules into crystalline materials are also covered. These particularly include the incorporation of compounds as solid solutions, but also eutectic formation and inclusion at surfaces during crystal growth. The relationship between types of impurities and behavior during processing is also examined.

Thermochemical stability: A comparison between experimental and predicted data

The first step to be performed during the development of a new industrial process should be the assessment of all hazards associated to the involved compounds. Particularly, the knowledge of all substances thermochemical parameters is a primary feature for such a hazard evaluation. CHETAH (CHEmical Thermodynamic And Hazard evaluation) is a prediction software suitable for calculating potential hazards of chemicals, mixtures or a single reaction that, using only the structure of the involved molecules and Benson’s group contribution method, is able to calculate heats of formation, entropies, Gibbs free energies and reaction enthalpies. Because of its ability to predict the potential hazards of a material or mixture, CHETAH is part of the so-called “desktop methods” for early stage chemical safety analysis. In this work, CHETAH software has been used to compile a complete risk database reporting heats of decomposition and Energy Release Potential (ERP) for 342 common use chemicals. These compounds have been gathered into classes depending on their functional groups and similarities in their thermal behavior. Calculated decomposition enthalpies for each of the compounds have also been compared with experimental data obtained with either thermoanalytic or calorimetric techniques (Differential Scanning Calorimeter – DSC – and Accelerating Rate Calorimeter – ARC).

Propesticides and their use as agrochemicals

The synthesis of propesticides is an important concept in design of modern agrochemicals with optimal efficacy, environmental safety, user friendliness and economic variability. Based on increasing knowledge of the biochemistry and genetics of major pest insects, weeds and agricultural pathogens, the search for selectivity has become an ever more important part of pesticide development and can be achieved by appropriate structural modifications of the active ingredient. Propesticides affect the absorption, distribution, metabolism and excretion parameters, which can lead to biological superiority of these modified active ingredients over their non-derivatised analogues. Various selected commercial propesticides testify to the successful utilisation of this concept in the design of agrochemicals. This review describes comprehensively the successful utilisation of propesticides and their role in syntheses of modern agrochemicals, exemplified by selected commercial products coming from different agrochemical areas.

Microwave-Assisted Metal-Free Decarboxylative Iodination/Bromination of Isoxazole-4-carboxylic Acids

A microwave-assisted metal-free route to substituted 4-haloisoxazoles via decarboxylative halogenation of substituted isoxazole-4-carboxylic acids using N-iodosuccinimide (NIS) and N-bromosuccinimide (NBS) in the presence of K3PO4 is described. It was discovered that the substitutions present at the 3-position of differently 3,5-disubstituted isoxazoles influenced the outcome of the protocol. The methodology is compatible for performing decarboxylative halogenation followed by decarboxylative Suzuki-Miyaura and Sonogashira couplings as one-pot process.
