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.

Synthesis and biological evaluation of novel pyrazoline derivatives containing indole skeleton as anti-cancer agents targeting topoisomerase II

In order to develop potent anticaner agents, a novel series of 3-(1H-indol-3-yl)-2,3,3a,4-tetrahydrothiochromeno[4,3-c]pyrazole derivatives were synthesized. Structures of all compounds were confirmed. MTT assay has been employed to study antiproliferative activity of these compounds with four human cancer cell lines (MGC-803, Hela, MCF-7 and Bel-7404) and a normal cell line L929. Most of these compounds showed potential anticancer activity and low cytotoxicity on normal cell in vitro. 7d and 7f showed the best anticancer activity, whose IC50 value is 15.43 muM and 20.54 muM towards MGC-803, respectively. Most of them exhibited topoisomerase II selective inhibitory. Cleavage reaction assay and DNA unwinding assay showed that 7f was a nonintercalative Topo II catalytic inhibitor, which was consistent with the docking results. Laser scanning confocal microscopy system tracks the location of representative compounds 7d and 7f which can be abundantly entering the nucleus. In particular, the most potent compounds 7d and 7f were shown to be able to induce G2/M cell cycle arrest and apoptosis in MGC-803 cells.

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.

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.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 288-14-2, and how the biochemistry of the body works.Reference of 288-14-2
