Transition Metal Directed Synthesis of Moracin M, a Phytoalexin of Morus alba Linn.

2-(5-Resorcinyl)benzofurans have been synthesised by the palladium catalysed cross coupling of 2-trimethylstannyl- or 2-bromozinc benzofurans with the appropriately functionalised 5-iodoresorcinols.These were synthesised by the tri-isopropylsilyloxy directed remote (C-5) lithiation/iodination of the O,O-di(triisopropylsilyl)resorcinoltricarbonylchromium(0) complex.The method was applied to the synthesis of moracin M, a phytoalexin of Morus alba Linn.

Non-linear Least Squares Program for the Analysis of 13C Spin-Lattice Relaxation Data based on a Symmetric Top Model. Description of the Method and Application

A non-linear least squares program has been developed to analyse data for the dipole-dipole relaxation time of carbon (T1DD) based on the symmetric top model of molecular rotational diffusion.The program employs four parameters in the simulation, i.e. two rotational diffusion constants and two angles related to the axis of molecular motion.The internal rotation of methyl groups is also incorporated.The application of the program to methylbenzofurans indicated the reliability and wide applicability of the method.The factors affecting the methyl rotation barrier are also examined with the aid of MNDO MO calculations, and a novel inter-relation is found with the bond length of C-CH3.

Quality by design in pharmaceutical manufacturing: A systematic review of current status, challenges and future perspectives

Quality by Design (QbD) was originated in the broad domain of Quality Management and was recently adapted and formalized in specific terms for assisting pharmaceutical companies efforts towards market and operational excellence. However, despite some impressive success stories, the pharmaceutical industry have not yet fully embraced QbD, particularly in routine commercial manufacturing (Rantanen and Khinast, 2015; Punal Peces et al., 2016). In this review, we aim to analyse the current state of implementation of QbD methodologies and tools in the pharmaceutical industry, extracting patterns and trends and identifying gaps and opportunities that may be considered to improve QbD adoption. For this purpose, a critical analysis of 60 research papers was performed, whose contents were classified, compared and summarized at different abstraction levels. Our analysis reveals the following tools as the frequently adopted for conducting each activity: Risk Assessment (RA) – Ishikawa Diagram, Failure Mode and Effects Analysis (FMEA) and Risk Estimation Matrix (REM); Screening Design of Experiments (DoE) ? 2-level Full and Fractional Factorial Designs; Optimisation DoE ? Central Composite Design (CCD). Emerging trends include the growing interest in quantifying and managing the impact of raw materials? attributes variability on process and product, as well as the development of Retrospective QbD approaches (rQbD) in complement to standard QbD.

3-(Oxazolo[4,5-b]pyridin-2-yl)anilides as a novel class of potent inhibitors for the kinetoplastid Trypanosoma brucei, the causative agent for human African trypanosomiasis

A whole organism high-throughput screen of approximately 87,000 compounds against Trypanosoma brucei brucei led to the recent discovery of several novel compound classes with low micromolar activity against this organism and without appreciable cytotoxicity to mammalian cells. Herein we report a structure-activity relationship (SAR) investigation around one of these hit classes, the 3-(oxazolo[4,5-b]pyridin-2-yl)anilides. Sharp SAR is revealed, with our most active compound (5) exhibiting an IC50 of 91 nM against the human pathogenic strain T.b. rhodesiense and being more than 700 times less toxic towards the L6 mammalian cell line. Physicochemical properties are attractive for many compounds in this series. For the most potent representatives, we show that solubility and metabolic stability are key parameters to target during future optimisation. (Chemical Equation Presented)

In vitro intrinsic clearance-based optimization of N3- phenylpyrazinones as corticotropin-releasing factor-1 (CRF1) receptor antagonists

A series of pyrazinone-based heterocycles was identified as potent and orally active corticotropinreleasing factor-1 (CRF1) receptor antagonists. Selected compounds proved efficacious in an anxiety model in rats; however, pharmacokinetic properties were not optimal. In this article, we describe an in vitro intrinsic clearance-based approach to the optimization of pyrazinone-based CRF1 receptor antagonists wherein sites of metabolism were identified by incubation with human liver microsomes. It was found that the rate of metabolism could be decreased by incorporation of appropriate substituents at the primary sites of metabolism. This led to the discovery of compound 12x, a highly potent (IC50 = 1.0 nM) and selective CRF1 receptor antagonist with good oral bioavailability (F = 52%) in rats and efficacy in the defensive withdrawal anxiety test in rats.

Synthesis and biological evaluation of novel shikonin-benzo[b]furan derivatives as tubulin polymerization inhibitors targeting the colchicine binding site

A novel series of shikonin-benzo[b]furan derivatives were designed and synthesized as tubulin polymerization inhibitors, and their biological activities were evaluated. Most compounds revealed the comparable anti-proliferation activities against the cancer cell lines to that of shikonin and simultaneously low cytotoxicity to non-cancer cells. Among them, compound 6c displayed powerful anti-cancer activity with the IC50 value of 0.18 muM against HT29 cells, which was significantly better than that of the reference drugs shikonin and CA-4. What’s more, 6c could inhibit tubulin polymerization and compete with [3H] colchicine in binding to tubulin. Further biological studies depicted that 6c can induce cell apoptosis and cell mitochondria depolarize, regulate the expression of apoptosis related proteins in HT29 cells. Besides, 6c actuated the HT29 cell cycle arrest at G2/M phase, and influenced the expression of the cell-cycle related protein. Moreover, 6c displayed potent inhibition on cell migration and tube formation that contributes to the antiangiogenesis. These results prompt us to consider 6c as a potential tubulin polymerization inhibitor and is worthy for further study.

Highly soluble phenylethynyl terminated oligoimides derived from 5(6)-amino-1-(4-aminophenyl)-1,3,3-trimethylindane, 4,4?-oxydianiline and mixed thioetherdiphthalic anhydride isomers

Novel highly soluble phenylethynyl-endcapped oligoimides derived from mixed thioetherdiphthalic anhydride isomers (m-TDPA) and 5(6)-amino-1-(4-aminophenyl)-1,3,3-trimethylindane (DAPI), 4,4?-oxydianiline (4,4?-ODA) with 4-phenylethynylphthalic anhydride (PEPA) as a reactive endcapping agent were synthesized. The calculated molecular weights of all the oligoimides were 2500?g¡¤mol?1.The effect of the mole ratio of DAPI/4,4?-ODA on solubility and melt viscosity of oligoimides as well as the thermal and mechanical properties of cured polyimide films was investigated. Experimental results indicated that DAPI greatly improved the solubility (>30?wt.%) of the oligoimides in low boiling points solvents when the content of DAPI was more than 10?mol% per total diamine. All the oligoimides exhibited very good processability with minimum melt viscosity lower than 60?Pa¡¤s at about 330?C. Tough and brown films were obtained after thermally cured at 370?C for 1?h and dynamic mechanical analysis (DMA) showed that glass transition temperatures of the cured films increased up to 340?C with the increasing content of DAPI. However, the thermal stability and mechanical properties decreased with the increase of DAPI content. The temperature of 5% weight loss was higher than 470?C in both air and N2 atmosphere obtained by thermogravimetric analysis (TGA). And the tensile strengths of the cured films were about 60?MPa.
