Aryl ethynyl terminated imide oligomers and their cured polymers

As part of a program to develop resins for high-performance/high-temperature aerospace structural applications, preliminary neat resin properties of naphthylethynyl terminated imide oligomers were determined and compared with the corresponding phenylethynyl terminated imide oligomers. Prior to oligomer work, four naphthylethynyl and phenylethynyl phthalimide and four naphthylethynyl and phenylethynyl naphthalimide model compounds were prepared and their thermal properties compared. The naphthylethynyl end-caps in N-phenyl- or N-naphthylphthalimide model compounds reacted at a lower temperature than the phenylethynyl end-cap in the same compounds, as previously reported. In contrast to these results, replacement of the phthalimide groups with naphthalimide groups showed that the phenylethynyl end-cap reacted at a lower temperature than the naphthylethynyl end-cap. Four aryl ethynyl terminated imide oligomers having the same imide backbone and molecular weight but different terminal units were prepared and the properties of the cured polymers compared. Phenylethynyl end-capped or naphthylethynyl end-capped oligomers, cured at 340 or 371C, exhibited similar tensile properties in thin films. The chemistry and properties of these materials are presented.

Design and synthesis of tailored human caseinolytic protease P inhibitors

Human caseinolytic protease P (hClpP) is important for degradation of misfolded proteins in the mitochondrial unfolded protein response. We here introduce tailored hClpP inhibitors that utilize a steric discrimination in their core naphthofuran scaffold to selectively address the human enzyme. This novel inhibitor generation exhibited superior activity compared to previously introduced beta-lactones, optimized for bacterial ClpP. Further insights into the bioactivity and binding to cellular targets were obtained via chemical proteomics as well as proliferation- and migration studies in cancer cells.

LOW DIELECTRIC CONSTANT, LOW DIELECTRIC DISSIPATION FACTOR COATINGS, FILMS AND ADHESIVES

Curable functionalized imide-linked polyimides compounds have been synthesized that have been found to possess very low dielectric constant and extremely low dissipation factor. These compounds also have a range of high to low modulus, extremely low moisture uptake and are very thermally stable. The combination of these materials in formulation along with functionalized polyethylene, polypropylene, polybutadiens have been found to be ideal for forming films and coatings for the microelectronic applications, multiplayer capacitors and interconnects, and high power cables and wire coatings. The addition of perfluorinated hydrocarbons, and POSS nanoparticles to the formulations have decreased the dielectric constant and dielectric dissipation factor further, and have also improved the flammability of the compositions.

Structure-activity relationships of a series of substituted benzamides: Potent D2/5-HT2 antagonists and 5-HT1a agonists as neuroleptic agents

A series of substituted (4-(4-(1,2-benzisothiazol-3-yl)-1-piperazinyl)butyl)benzamide derivatives was prepared and evaluated as potential atypical antipsychotic agents. The target compounds were readily prepared from their benzoyl chloride, benzoic acid, or isatoic anhydride precursors, and they were evaluated in vitro for their ability to bind to dopamine D2, serotonin 5-HT2, and serotonin 5-HT1a receptors. To assess the potential antipsychotic activity of these compounds, we investigated their ability to inhibit the apomorphine-induced climbing response in mice. Selected compounds were evaluated further to determine their side-effect potentials. Structure-activity relationships of both mono- and polysubstituted benzamides are discussed herein. While several analogues had potent in vitro and in vivo activities indicative of potential atypical antipsychotic activity, anthranilamide 77 (1192U90) demonstrated a superior pharmacological profile. As a result of this investigation, 1192U90 (2-amino-N-(4-(4-(1,2-benzisothiazol-3-yl)-1-piperazinyl)butyl)benzamide hydrochloride) was selected for further evaluation and is currently in phase I clinical trials as a potential atypical antipsychotic agent.

Design and synthesis of phthalimide-type histone deacetylase inhibitors

Several hydroxamic acid derivatives with a substituted phthalimide group as a linker and/or cap structure, prepared during structural development studies based on thalidomide, were found to have histone deacetylase (HDAC)-inhibitory activity. Structure-activity relationship studies indicated that nature of the substituent introduced at the phthalimide nitrogen atom, introduction of a hydroxamic acid structure, and distance between the N-hydroxyl group and the cap structure are important for HDAC-inhibitory activity.

In Vitro Antitumor Activity of Newly Synthesized Pyridazin-3(2H)-One Derivatives via Apoptosis Induction

Systemic toxicity associated with drug resistance continues to be the major obstacle to curative therapy of cancer. Tumor cell resistance to chemotherapeutic drugs often results in coordinate resistance to other structurally and functionally unrelated drugs and the subsequent development of cross resistance phenotype. Therefore, it seems necessary to identify new molecules as anticancer agents. In this process, we synthesized a series of new pyridazin-3(2H)-one derivatives and evaluated their antitumor potential. These cyclic molecules were synthesized and designed as a combination of benzofuran with pyridazinones. All final compounds have been characterized by spectral and elemental analyses to confirm successful synthesis reactions. To evaluate their anticancer activity, all derivatives were assessed against the human breast adenocarcinoma cell line (MCF-7) and the murine mastocytoma cell line (P815) using the methyl tetrazolium Test (MTT assay). The cytotoxic activity was found to be dose-dependent and the IC50 values of the synthesized compounds ranged from 14.5 to 40 muM against MCF-7 and from 35 to 82.5 muM against P815. At the same time, no cytotoxic activity was observed against normal cells. In order to investigate the molecular mechanism of the most cytotoxic product (6f), apoptosis induction was measured against MCF-7 cells. Using the annexin-V FITC staining technique, we showed that the cytotoxic effect of this product is associated with apoptosis induction.

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.
